Petermann Glacier ( Danish : Petermann Gletsjer ) is a large glacier located in North-West Greenland to the east of Nares Strait . It connects the Greenland ice sheet to the Arctic Ocean at 81°10' north latitude, near Hans Island .

188-430: The glacier and its fjord are named after German cartographer August Heinrich Petermann . The tidewater glacier consists of a 70 km (43 mi) long and 15 km (9 mi) wide floating ice tongue whose thickness changes from about 600 m (2,000 ft) at its grounding line to about 30–80 metres (100–260 ft) at its front. Rough mass balance estimates using these scales suggest that about 80% of its mass

376-588: A 750 km long subglacial canyon running from the center of the island northward to the fjord of the Petermann Glacier. Dubbed " Greenland Grand Canyon " by media, the bottom is below sea level, and the canyon is likely to have influenced basal water flow from the ice sheet interior to the margin. The canyon predates ice sheet inception and has influenced basal hydrology in Greenland over past glacial cycles. The US Coast Guard icebreaker " USCGC Healy " entered

564-402: A clear summer's day descry snow-covered mountains at a great distance to the north." Heinrich Berghaus, Petermann's teacher, included this information in the right hand corner on his isotherm map of 1838 for his Physikalische Atlas with the text 'possible polar land' [Wahrscheinliches Polar-Land]. So it might be that Petermann based his views on this information. He published the same map of

752-607: A decade of reliance on the Russians. In 2019, NASA announced the Artemis program , intending to return to the Moon and establish a permanent human presence. This was paired with the Artemis Accords with partner nations to establish rules of behavior and norms of space commercialization on the Moon. In 2023, NASA established the Moon to Mars Program office. The office is designed to oversee

940-466: A few well-known sorts, like the stereographic and orthographic equatorial projections and the projections of Lambert , Flamsteed and Mercator , remained the most popular. Petermann did publish reports on the new projection methods of J. Babinet (1854) and J. James (1857), and G. Jäger, but he hardly used them. Though Petermann and Ernst Behm (1830–1884; like many of the famous Gothaer geographers and cartographers Behm had first another profession. He

1128-719: A fifth of the time and a fourth of the costs. In 1857 the President of the Royal Geographical Society, Sir Roderick Murchison , praised PGM for its fast reporting of diverse explorations, and spoke against the jealousy of those in his own Society who felt that exploration supported primarily by the British should first be published in Britain: he thought the Perthes Institute enriched the scientific geographic discourse. Since he

1316-595: A finger of permanent pack ice stretching from the north to approximately 76°, which made progress further north impossible. Petermann was undaunted in his endeavors to reach the North Pole and demonstrate a possible passage to the Pacific Ocean , even after this expedition had failed in that respect. In 1869 he published a map of the Arctic Ocean north of Wrangel Island with all exploration routes between 1648 and 1867 and

1504-466: A human in space, develop tracking and control systems, and identify other issues associated with human spaceflight. While much of NASA's attention turned to space, it did not put aside its aeronautics mission. Early aeronautics research attempted to build upon the X-1's supersonic flight to build an aircraft capable of hypersonic flight . The North American X-15 was a joint NASA–U.S. Air Force program, with

1692-660: A lot of time on the active promotion of his exploratory missions, especially the polar regions. For this he wrote more articles than for any of his other ventures. Up to 1871 he published seventeen maps of the Arctic and Antarctic in the regular issues and eight in the 'supplement' issues. He began publishing notices on the geography and exploration of the polar regions in PGM 38, 1871 ( Geographie und Erforschung der Polar-Regionen started in 1865 and nos. 51–135 appeared in PGM volumes 16, 1871 to 23, 1878), and from that time onwards 195 maps covered

1880-669: A map with sea-temperatures in the Greenland Sea and the Norwegian Sea as observed by the German expedition, and again two maps of the German expedition in Ergänzungsheft 28. In 1874 he again published an overview map of the Arctic at a scale of 1:16,000,000, this time with exploration routes from 1616 to the end of 1874, complemented by the new meteorological weather stations. Strangely enough,

2068-630: A map, concerning among other things lake Uniamesi , he tends to disagree with Jakob Erhardt , one of the missionaries of the Church Mission Society of London, concerning its situation and extension. Erhardt was erroneous in that he situated the lower tip of the lake around 13° South 36° East and made it bend westward to 28° East, with a probable extension to 24° East. Furthermore, he thought that Lake Victoria , Lake Tanganyika and Lake Nyassa were one inland sea extending to 6° North. A lack of data led Petermann to agree with his erroneous shape of

2256-570: A permanently manned space station and to do it within a decade. In 1985, NASA proposed the Space Station Freedom , which both the agency and President Reagan intended to be an international program. While this would add legitimacy to the program, there were concerns within NASA that the international component would dilute its authority within the project, having never been willing to work with domestic or international partners as true equals. There

2444-628: A possible source of antimatter at the center of the Milky Way and observing that the majority of gamma-ray bursts occur outside of the Milky Way galaxy. The Chandra X-ray Observatory was launched from the Columbia on STS-93 in 1999, observing black holes, quasars , supernova , and dark matter . It provided critical observations on the Sagittarius A* black hole at the center of the Milky Way galaxy and

2632-519: A preamble by Behm) and map appeared four months after the Vega had arrived in Irkutsk . Hassenstein drafted the new map, maybe using the older draft. The title was hammered out of the old copperplate and replaced by a new one, while Nordenskiöld's data were engraved, and printed in red, making it look like an overlay on the old map. Because of the use of lighter background colors the newer map looks much fresher than

2820-469: A precursor to natural ice calving from Petermann Glacier. A large chunk estimated to be 100 square miles (260 km) calved off the glacier in August, 2010. The Danish Meteorological Institutes maintains an archive of imagery of Petermann Glacier and adjacent coastal areas of Greenland from both European and US satellites and sensors such as Envisat , MODIS , and AVHRR . Data from Operation IceBridge show

3008-442: A quality corresponding to the then-current view of the geographic sciences. Because of all these contacts, the students were confronted with many opinions and views on the state of science and the world that would not normally have been part of their curriculum. Besides, we may take Poggendorff seriously when he sees Petermann as 'private secretary and librarian of H.K.W. Berghaus' in the years 1839–45, so we can assume that Petermann

3196-480: A reporter for a London periodical ( Athenaeum , journal of literature, science and the fine arts . London, 1828–1921), and in 1850 founded his own establishment: The Geographical Establishment, Engraving, Lithographic and Printing Office, 9 Charing Cross. In 1852 the young Ernst Georg Ravenstein (1834–1913) was apprenticed to him before he went in 1855 into the service of the Topographical Department of

During his time in Edinburgh, he may have come into contact with the publisher G.H. Swanston, for whom he constructed several maps for The Royal Illustrated Atlas, Of Modern Geography , 1st edition published in 27 parts 1854–62. and republished probably in 1872. He also may have met John Bartholomew Jr. (1831–1893) in Edinburgh, who created many maps in

3572-540: A simple presentation of the itinerary by also describing the area explored with all knowledge available and pointing out gaps that remained to be filled in the current knowledge. So the impact was reciprocal. Moreover, Petermann gave directions to explorers in exchange for which he was allowed to publish their results as soon as possible. The influence Petermann tried to wield, even as a young man, can best be illustrated by his interference, together with Bunsen and Ritter, on behalf of Heinrich Barth , who wished to take part in

3760-532: A space station since the agency was created. In 1973, following the end of the Apollo lunar missions, NASA launched its first space station, Skylab , on the final launch of the Saturn   V. Skylab reused a significant amount of Apollo and Saturn hardware, with a repurposed Saturn   V third stage serving as the primary module for the space station. Damage to Skylab during its launch required spacewalks to be performed by

3948-496: A teacher in the 2nd course of Berghaus' school. In April 1845, he followed Lange, who received him in his house in Edinburgh and acquainted him with the friends he had made. Together they went on a tour through the Grampians , applying what they had learned by using barometers for height measurements and taking geological and botanical samples. Meanwhile, they also worked on Johnston's Physical atlas ( Physical geography, illustrating in

4136-583: A true representation of reality (this is illustrated by the depiction of the Liparian Isles , which were not securely situated until Darondeau's French survey in 1858 ), let alone medium- and small-scale maps of the interior of continents and the polar regions. One could still hardly speak of dense topographic, orographic and hydrological information. Though the maps in the Stieler looked dense with information, they were mainly filled out with information where space in

4324-442: A volume containing its ten-year history of exploration and discoveries, but in order not to raise the retail price of the map he satisfied himself with merely citing the volumes of PGM where the information could be found and providing an accompanying 43-page geographical-statistical compendium by C.E. Meinicke. In 1875 a second revised edition appeared, with a small sample in PGM. We unfortunately do not find his famous six-sheet map of

4512-418: A way to honour Petermann. The map shows clearly to what degree the descriptive data of older explorations (i.e. Vasili Pronchishchev , 1735–36; Hariton Laptev, 1739–43; Semyon Čeluskin , 1735–43; Fyodor Minin and Dmitriy Sterlegov, 1740; and Alexander Theodor von Middendorff , 1843) could be trusted when drafting a map from many sources and trying to amalgamate them into a single image. The difference between

4700-418: Is in the modified polar projection first proposed by G. Jäger of Vienna . Jäger had developed this projection specifically to facilitate the palaeontological analysis of the inventory of animal life in the Arctic area. Petermann thought this the best projection for planning the laying of telegraph lines. He not only promoted explorations, but also actively collected funds to realize them, and gave an account of

4888-474: Is inserted (I do not know if it exists in Barth's work). All in all, there is little overlap, also because the scales used for the different works are mostly different. But the smaller maps are clearly generalizations of the maps in Barth's work. The images in Barth's look sharper, but of course that is also because they are engraved on a larger scale, while all the areas outside the routes, of which nothing or not enough

5076-504: Is known are blank. These routes, like many others, were reused in many new maps, such as Barth's route, supplemented with the 1828 routes of René-Auguste Caillé (1799–1838) and Léopold Planet (1850). PGM not only reported the findings of explorers but also was proactive in instigating new explorations. Ergänzungsband II of 1863 contains a 10-part map (210x102 cm) of Africa ( Karte von Inner-Afrika , that contained all routes of explorers between 1701 and 1863. The most important parts of

5264-493: Is lost as basal meltwater, yet little oceanographic data are available to connect Petermann Glacier to its fjord and adjacent Nares Strait. Even the sill depth and location is largely unknown, as modern soundings of the fjord , with its mouth located between Cape Morton and Cape Tyson , are still lacking. Petermann Glacier marks the western limit of Hall Land and the eastern limit of Daugaard-Jensen Land . The Petermann Peninsula flanks its northern end. The grounding line

5452-438: Is relatively stable with on average 470 m variation over the period 1992 to 2011. This indicates that the glacier was dynamically stable. A series of satellite images from 2002 through 2009 illustrate that the terminus of the glacier has advanced towards the ocean, however, several lateral rifts have developed also. The distance of this rifts or cracks back from the terminus has diminished for this time period also and may serve as

That helped him to read as widely as necessary for his further career. His love for

In 1868 he was awarded with the prestigious 'Founders medal' of the RGS. Queen Victoria , at the suggestion of Robert Bunsen , appointed him 'physical geographer-royal'. Early in his career, Petermann already wanted to further the cause of geographical exploration as shown by his concern for and interference with James Richardson 's expedition. The purpose of this expedition, which

8460-631: The STS-1 mission, designed to serve as a flight test for the new spaceplane. NASA intended for the Space Shuttle to replace expendable launch systems like the Air Force's Atlas , Delta , and Titan and the European Space Agency 's Ariane . The Space Shuttle's Spacelab payload, developed by the European Space Agency, increased the scientific capabilities of shuttle missions over anything NASA

The successful completion of the passage during Nordenskiöld's expedition with the steamship Vega was published in 1879 in PGM shortly after Petermann's death. The map was drafted on top of Petermann's 1873 map of Siberia. The route of the Vega had also appeared on a Russian copy of Petermann's 1873 map. The PGM editors also added it in their 1879 map. This might have been

He measures the unexplored area in the Arctic as 140,000 German square miles (approximately 7,700,000 km²), comparing it to Australia's total of 138,000. The unexplored Antarctic he calculates as 396,000 German square miles (approximately 21,800,000 km²). Petermann uses the map specifically to show the benefits of using ships for exploration, rather than

This led to many new German expeditions to Africa (by Theodor von Heuglin , Hermann Steudner , Theodor Kinzelbach, Karl Moritz von Beurmann , Gerhard Rohlfs , Karl Mauch and others), most financed by gifts due largely to Petermann's agitating actions and publications. Many found their death in Africa as shown in the map with the subtitle Four martyrs of German science in Inner-Africa shows, i.c. Overweg, Vogel, Beurmann and Steudner. Petermann first drafted maps of Barth & Overweg's routes for

Though he even tried to get Bismarck involved in an Arctic exploration project, it was shelved for some time because of the Austro-Prussian War and the consequent expansion of the Prussian realm. In PGM that same year, he again turned to the FDH for support. In 1868 Petermann roused so much support for his idea in

In his last article published before his death, Petermann speaks enthusiastically about the newly developed photogravure , which considerably reduced costs per map while also increasing production speed. In his opinion the 715-sheet Austrian map was probably twenty times more efficiently produced than an engraved version would have been, for its production took only

Debes neuer Handatlas , later called Grosser Columbus Weltatlas ), Carl Barich, Arnim Welcker (1840–1859), Ludwig Friederichsen (who worked on the Stieler and PGM from 1859 to 1863, and later founded the geographical society of Hamburg and became very active in German colonial politics.) in

13536-558: The Keplar space telescope confirmed was Kepler-22b , orbiting within the habitable zone of its star. NASA also launched a number of different satellites to study Earth, such as Television Infrared Observation Satellite (TIROS) in 1960, which was the first weather satellite. NASA and the United States Weather Bureau cooperated on future TIROS and the second generation Nimbus program of weather satellites. It also worked with

13724-548: The Martian interior. The 2021 Perseverance rover carried the first extraplanetary aircraft, a helicopter named Ingenuity . NASA also launched missions to Mercury in 2004, with the MESSENGER probe demonstrating as the first use of a solar sail . NASA also launched probes to the outer Solar System starting in the 1960s. Pioneer 10 was the first probe to the outer planets, flying by Jupiter , while Pioneer 11 provided

13912-472: The Moon and going to Mars. Embracing this approach, NASA's Commercial Crew Program started by contracting cargo delivery to the International Space Station and flew its first operational contracted mission on SpaceX Crew-1 . This marked the first time since the retirement of the Space Shuttle that NASA was able to launch its own astronauts on an American spacecraft from the United States, ending

14100-676: The Naval Research Laboratory's Project Vanguard, the Army's Jet Propulsion Laboratory (JPL), and the Army Ballistic Missile Agency under Wernher von Braun . This left NASA firmly as the United States' civil space lead and the Air Force as the military space lead. Plans for human spaceflight began in the U.S. Armed Forces prior to NASA's creation. The Air Force's Man in Space Soonest project formed in 1956, coupled with

14288-494: The North pole starting from Baffin Bay. In several articles he tries to persuade the RGS to support his plan to start the expedition from Spitsbergen and use steamships instead of sledges for transport. In one article he stresses his love for Arctic expeditions by reminiscing: "Who, like us, e.g. has attended the accounts of one capt. Inglefield ( Edward Augustus Inglefield (1820–1894)) during

14476-494: The Perthes collections in Gotha . Berghaus had been riding numerous hobbyhorses (terrain representation, isolines , scale indicators, map projections , etc.) without much success, but now he could finally put them to work with his pupils. He very successfully disseminated many of his ideas and concepts. Moreover, his students somehow learned better than he to limit their endeavors in order to bring more of them to full fruition. Though

14664-514: The Perthes' offer of work in 1854. Early in his German career here Petermann was appointed first professor (1854) and later honorary doctor (1855) of the University of Göttingen by the Duke of Gotha . Bernhardt Perthes hired him with the prospect of playing an important role in the establishment of his geographical institute. At the same time, his friend Henry Lange also started to work with Perthes. When he

14852-700: The Pilotless Aircraft Research Division. The Soviet Union's launch of Sputnik 1 ushered in the Space Age and kicked off the Space Race . Despite NACA's early rocketry program, the responsibility for launching the first American satellite fell to the Naval Research Laboratory 's Project Vanguard , whose operational issues ensured the Army Ballistic Missile Agency would launch Explorer 1 , America's first satellite, on February 1, 1958. The Eisenhower Administration decided to split

15040-680: The Prussian atlas, and the maritime atlas. August Petermann gained commercial insight during his years in the cartography business in Edinburgh and London from 1845 to 1854. Normally he would have been obliged to work in Berghaus' school until 1849, as it was laid down in the contracts the students had to sign. These stated that the students had to work for five years after they finished their studies to pay for their tuition. In 1842, Alexander Keith Johnston (1804–1871) visited Gotha to discuss several projects with Perthes. These negotiations first resulted in

15228-518: The Richardson expedition. He later also persuaded the English government to send Eduard Vogel after them for scientific research and astronomical observations. Petermann published the results under the title Account of the expedition to Central-Africa . When first Barth and later Vogel failed to return at the expected time Germany frantically tried to discover their fate, much as Britain had with Franklin in

15416-599: The Russians be included. In 1993, the Clinton Administration announced that the Space Station Freedom would become the International Space Station in an agreement with the Russian Federation. This allowed the Russians to maintain their space program through an infusion of American currency to maintain their status as one of the two premier space programs. While the United States built and launched

15604-507: The Russians to fly to the International Space Station for four days, despite the opposition of NASA to the idea. Advocates of this new commercial approach for NASA included former astronaut Buzz Aldrin , who remarked that it would return NASA to its roots as a research and development agency, with commercial entities actually operating the space systems. Having corporations take over orbital operations would also allow NASA to focus all its efforts on deep space exploration and returning humans to

15792-422: The Solar System. Mars has long been a planet of intense fascination for NASA, being suspected of potentially having harbored life. Mariner 5 was the first NASA spacecraft to flyby Mars, followed by Mariner 6 and Mariner 7 . Mariner 9 was the first orbital mission to Mars. Launched in 1975, Viking program consisted of two landings on Mars in 1976. Follow-on missions would not be launched until 1996, with

15980-602: The Space Shuttle Columbia disaster in 2003, NASA was forced to rely on Russian Soyuz launches for its astronauts and the 2011 retirement of the Space Shuttle accelerated the station's completion. In the 1980s, right after the first flight of the Space Shuttle, NASA started a joint program with the Department of Defense to develop the Rockwell X-30 National Aerospace Plane. NASA realized that

16168-418: The Space Shuttle allowed NASA to begin recruiting more non-military scientific and technical experts. A prime example is Sally Ride , who became the first American woman to fly in space on STS-7 . This new astronaut selection process also allowed NASA to accept exchange astronauts from U.S. allies and partners for the first time. The first Space Shuttle flight occurred in 1981, when the Columbia launched on

16356-505: The Space Shuttle and expand space exploration beyond low Earth orbit. Constellation was intended to use a significant amount of former Space Shuttle equipment and return astronauts to the Moon. This program was canceled by the Obama Administration . Former astronauts Neil Armstrong , Gene Cernan , and Jim Lovell sent a letter to President Barack Obama to warn him that if the United States did not get new human spaceflight ability,

16544-544: The Space Shuttle began flying, selling it as an orbital laboratory, repair station, and a jumping off point for lunar and Mars missions. NASA found a strong advocate in President Ronald Reagan , who declared in a 1984 speech: America has always been greatest when we dared to be great. We can reach for greatness again. We can follow our dreams to distant stars, living and working in space for peaceful, economic, and scientific gain. Tonight I am directing NASA to develop

16732-660: The Space Shuttle, while a massive technological accomplishment, would not be able to live up to all its promises. Designed to be a single-stage-to-orbit spaceplane, the X-30 had both civil and military applications. With the end of the Cold War , the X-30 was canceled in 1992 before reaching flight status. Following the Space Shuttle Columbia disaster in 2003, President Bush started the Constellation program to smoothly replace

16920-483: The Space Shuttle. Due to technical challenges, the spacecraft was cancelled in 2001. Despite this, it was the first time a commercial space company directly expended a significant amount of its resources into spacecraft development. The advent of space tourism also forced NASA to challenge its assumption that only governments would have people in space. The first space tourist was Dennis Tito , an American investment manager and former aerospace engineer who contracted with

17108-507: The Space Station Freedom was controversial, with much of the debate centering on cost. Several redesigns to reduce cost were conducted in the early 1990s, stripping away much of its functions. Despite calls for Congress to terminate the program, it continued, in large part because by 1992 it had created 75,000 jobs across 39 states. By 1993, President Bill Clinton attempted to significantly reduce NASA's budget and directed costs be significantly reduced, aerospace industry jobs were not lost, and

17296-522: The Swedish icebreaker Oden served as the platform for the research carried out in the sea, on the glacier and on land. The purpose of the Swedish-American research expedition was to collect multibeam bathymetry and sub-bottom profile information along the western continental shelf of Greenland in order to characterize the shape of the seafloor and uppermost sediment properties. The main goal was to increase

17484-578: The U.S. risked become a second or third-rate space power. As early as the Reagan Administration, there had been calls for NASA to expand private sector involvement in space exploration rather than do it all in-house. In the 1990s, NASA and Lockheed Martin entered into an agreement to develop the Lockheed Martin X-33 demonstrator of the VentureStar spaceplane, which was intended to replace

17672-484: The United States ( Neue Karte der Vereinigten Staaten vor Nord-Amerika in 6 Blättern ) in the issues of PGM. It was produced for the sixth edition of the Stieler on scale 1:3,700.000, though a small part appeared in the next annual as an illustration of the exploration of Northwest Texas. Several times Petermann indicated that he disagreed with the reports of explorers, probably basing his arguments on reports and literature at his disposal or on sound geographic reasoning. In

17860-658: The United States' military and civil spaceflight programs, which were organized together under the Defense Department 's Advanced Research Projects Agency . NASA was established on July 29, 1958, with the signing of the National Aeronautics and Space Act and it began operations on October 1, 1958. As the US's premier aeronautics agency, NACA formed the core of NASA's new structure by reassigning 8,000 employees and three major research laboratories. NASA also proceeded to absorb

18048-401: The adjacent territories. (A reasonable number of measuring points for precipitation and temperature maps would be 1,500 and 600 per 100,000 km² respectively to create acceptable isoline maps for these phenomena ). These give schematic negative relief maps, which hardly even approximate the true relief of the territory. Thoulet wanted to show that the few bathymetric measurements available for

18236-574: The authors' different interpretations. This was the case with, for example, the map of the Kerguelen and McDonald Islands sighted by John Heard (1853), William MacDonald (1854), Hutton (1854), Attway (1854), Rees (1854), and Neumayer (1857), with several comparisons of explorations since James Cook . The same with small maps (scale ca. 1:33,000,000) of the central part of southern Africa, which shows different interpretations by Heinrich Kiepert (1855), J. McQueen (1857) and David Livingstone (1857). Or with

18424-503: The coastlines on the two maps sometimes can be as much as ½° latitude and 1° longitude. Looking at the Taimyr peninsula , the channel between it and the mainland is reduced from approximately 10 km to a few kilometres by the Swedish exploration. The only exception was the information derived from P.F. Anjou (1823), which was based on astronomical observations, and is the same in both maps. The article (translations from Swedish and Danish with

18612-511: The considerable information and maps available in the Perthes Institute. This fund of knowledge grew to be so large that the Institute soon had a large library of manuscripts, books, atlases, and maps at its disposal that could vie with any university or society collection. In the 1980s it was thought that the Perthes-archives contained 180,000 printed maps and around 2,800 atlases. In the 1990s

18800-542: The earth is far less than is generally supposed. ... [In the maps,] even the African and Australian terrae incognitae shrink more and more, and there remain [only] a few blank spots, maybe 'wild territories', where there is 'nothing'. In reality everything we see on our maps is just the first step, the beginning of a more accurate knowledge of the earth’s surface." Only in the detailed maps in PGM, where many spaces were left blank, could one really judge how haphazard and incomplete

18988-436: The elucidation of the unknown, and to offer a means for friends at home to follow their moves and to judge the value of their labour. This by creating a cartographic representation of the least known central regions of Africa utilizing all material at hand as completely as possible, to display the range of our contemporary knowledge as well as the way this knowledge is acquired and the degree of its reliability." Petermann spent

19176-564: The end of the 1960s and installed James E. Webb as NASA administrator to achieve this goal. On May   25, 1961, President Kennedy openly declared this goal in his "Urgent National Needs" speech to the United States Congress, declaring: I believe this Nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to Earth. No single space project in this period will be more impressive to mankind, or more important for

19364-517: The estimate was 1,000 m of archive, some 400,000 maps (including manuscripts), and some 120,000 geographical works. All collections (currently estimated at 185,000 sheets of maps, 120,000 geographical works, and 800 m of archives) were acquired in 2003 by the Free State of Thüringen and deposited with the library of the University of Erfurt in its research center in Gotha . But the maps went beyond

19552-564: The event was related to global warming or not. The Select Committee on Energy Independence and Global Warming of the US House of Representatives held hearings on Petermann Glacier and the Greenland icesheet within days of the 2010 break-up. The National Ice Center named the new iceberg, the Petermann Ice Island (2010) to differentiate it from a similar calving event two years earlier which produced Petermann Ice Island (2008). That island

19740-578: The example of the school for engravers at the Archives Militaires Generales in Paris (founded in 1811). During its existence, Berghaus's academy offered only three courses, and only a few students attended: Petermann's father, August Rudolf Petermann, who was a registrar at Bleicherode , could not pay for the further education of his son. When he read the advertisement for Berghaus' school he sent his son's maps and other work for evaluation. One of

19928-543: The exploration of the polar regions probably started in London, for many of the polar explorers, especially after the disappearance of the Franklin expedition , presented their discoveries to the Royal Geographical Society. From 1848 onward he published, among other things, the following articles and maps with English publishers or in English language journals: It is no surprise to see that his sphere of interest in 'current' geography,

20116-584: The exquisite expression copper engravings could reach. So the students mainly learned this art. Only at the end of his life did Petermann became more enthusiastic about lithography, which had advanced by then. Up to and including the 10th edition of the Stieler Handatlas (1920–1925) the Perthes Institute, where he worked from 1854 onwards, used copperplate engravings as the basis for its maps. Some 460 copperplates of this edition are currently preserved in

20304-501: The extension of Greenland. He wrote: "... but such an enormous glacier like the one named after Von Humboldt points at extensive eternal snow and glacier regions and this speaks for an extension of Greenland to the North ..." His view may have been reinforced by some explorers who sighted land at higher latitudes than the tip of Greenland. While Petermann was honored in 1876 by the American Geographical Society , during

20492-420: The first close up view of the planet. Both probes became the first objects to leave the Solar System. The Voyager program launched in 1977, conducting flybys of Jupiter and Saturn , Neptune , and Uranus on a trajectory to leave the Solar System. The Galileo spacecraft, deployed from the Space Shuttle flight STS-34 , was the first spacecraft to orbit Jupiter, discovering evidence of subsurface oceans on

20680-510: The first crew to make it habitable and operational. Skylab hosted nine missions and was decommissioned in 1974 and deorbited in 1979, two years prior to the first launch of the Space Shuttle and any possibility of boosting its orbit. In 1975, the Apollo–Soyuz mission was the first ever international spaceflight and a major diplomatic accomplishment between the Cold War rivals, which also marked

20868-450: The first humans to see the Earth as a globe in space, the first to witness an Earthrise , and the first to see and manually photograph the far side of the Moon. The first lunar landing was conducted by Apollo   11. Commanded by Neil Armstrong with astronauts Buzz Aldrin and Michael Collins , Apollo   11 was one of the most significant missions in NASA's history, marking the end of

21056-865: The first issue of the fifth edition (1866–67) of the Stieler, he frequently referred to maps or articles published in PGM. Furthermore, he mentions that he is working on four other maps of Australia or parts of it. One of these is his famous eight-sheet map of Australia, scale 1:3,500,000, and the other three are concerned with exploration or based on land-property maps. ( Spezialkarte von Neu-Süd-Wales nach den Kataster-Aufnahmen , later published as Spezialkarte eines Theiles von New South Wales (PGM, 12, 1866, table 13); Spezialkarte vom See’ngebiet im Inneren von Australien , later published as Das See’n-Gebiet (Lake District) und die Steinige Wüste (Great Stony Desert) im Innern von Australien (PGM, 13, 1867, table 4); Karte der Entdeckungen im Inneren Australiens, scale 1:2,500,000 , which he probably chose not to publish in PGM due to all

21244-505: The fjord in 2007 and 2009. In 2009, scientists aboard the Greenpeace ship Arctic Sunrise conducted multi-disciplinary measurements at Petermann glacier to document the anticipated detachment of a large area of the glacier to obtain insight into glacier dynamics and to highlight glacier response to ongoing Arctic climate warming ahead of the Copenhagen summit . During the summer of 2015,

21432-688: The fjord on August 11, 2003 to survey bottom topography, ocean currents, and ocean chemistry as part of a larger program funded by the US National Science Foundation to better understand rates and mechanism by which Arctic sources of fresh water may impact the climate states of the North Atlantic. The program was continued as part of the Canadian International Polar Year projects when the CCGS Henry Larsen entered

21620-467: The floating portion of Petermann Glacier reducing its area and volume by about 25% and 10%, respectively. Researchers from the Canadian Ice Service located the calving from NASA satellite images taken on August 5; Patrick Lockerby re-posted cropped NASA images with interpretations on the internet the same day. It was the largest Arctic iceberg to calve since 1962, however, it is unclear whether

21808-485: The geographic knowledge was. J.G. Bartholomew in 1902 phrased Petermann's drive as: "The filling up of the blank spaces of the unknown in his maps had such a fascination for him that rest seemed impossible to him while any country remained unexplored". The results of the exploratory expeditions cried out for presentation in map form, and PGM published exploration results as quickly and accurately as possible. Petermann had all results he received from explorers checked against

21996-481: The great Swiss cartographer, in Berne and Zurich in 1960, and his son John Eric followed in 1977 with Imhof's pupil, Ernst Spiess. "Bartholomew is best known for the development of colour contouring (or hypsometric tints), the system of representing altitudes on a graduated colour scale, with areas of high altitude in shades of brown and areas of low altitude in shades of green. He first showcased his colour contouring system at

22184-458: The higher reaches might later have been used by Hermann Haack (1872–1966) for his Perthes' wall maps. Several maps were co-constructions of Petermann and Bartholomew. In 1847, Petermann moved to London with the intention of furthering his geographical studies and then returning to Germany. Soon, however, he decided to follow a professional career there as the environment he moved into seemed to be favorable for his prospects. In London, he worked as

22372-423: The horizontal positions of and distances between all points and localities, but also clearly distinguish vertical variations, from sea level to the highest summits." Petermann was responsible for drawing most of the maps in the first few years of the journal. His strength was in the analysis and evaluation of all sources available. As such one can say that the indication 'Originalkarte' (original map) in many titles

22560-433: The hypersonic test aircraft becoming the first non-dedicated spacecraft to cross from the atmosphere to outer space. The X-15 also served as a testbed for Apollo program technologies, as well as ramjet and scramjet propulsion. Escalations in the Cold War between the United States and Soviet Union prompted President John F. Kennedy to charge NASA with landing an American on the Moon and returning him safely to Earth by

22748-399: The image allowed, and the cartographers had little choice what to depict by the lack of known phenomena. The density of information did not indicate how thoroughly an area had been explored, for the cartographers selected their data and drafted the maps in such a way as to give a balanced image as possible. As Petermann put it in 1866: "In fact, our cartographic knowledge of the territories of

22936-637: The journal of the German Geographical Society and followed these up with maps in PGM in 1855, 1857, and 1859. These were later worked into the maps for Barth's voluminous work on his African voyage of 1850–55. The route maps were used in new maps up to 1893. When we compare the maps in Barth's work and in PGM we may get an idea of how the information was turned into images. The first map in Barth's work gives an overview of his routes. The routes of Livingstone have already been engraved, but have not been highlighted by coloring. The 1857 issue of PGM uses

23124-701: The journal were: Geographische Nekrologie des Jahres **** (1858–1884), Geographie und Erforschung Polar-Regionen (nr. 51/1871-nr. 135/1878), Monatsbericht über Entdeckungsgeschichte und Kolonisation (1885), Kleinere Mitteilungen (1889–1939), Geographischer Anzeiger (1899–1902), Kartographischer Monatsbericht aus Justus Perthes' Geographischer Anstalt in Gotha (1908–1911), Militärkartographie (1909–1914), Staaten und Völker (1923), Neue Forschung im Felde (1935–1939), (Wehr- und) Militärgeographie (1935–1936), Kartographie (1941–1945). Though Petermanns name appears on hundreds of maps, Wagner suggests he stopped drafting maps himself after 1862. The report concerning

23312-412: The knowledge of the area around Spitsbergen and the central Arctic. It contains articles by Petermann, R. Werner, N. Dunér and A.E. Nordenskiöld , Dr. Malmgrén, Barto von Löwenigh , and G. Jäger, and is accompanied by three maps. Petermann published this supplement issue to encourage people and institutes to support German efforts to explore the central Arctic. The first map, scale 1:40,000,000 covers both

23500-454: The lake or lakes, but he was not convinced of its wide extension to the west and north. As for the sources of the Nile he was not so much mistaken, as they were indicated by a text near the equator between 30° and 36° East, but this was not so hard to induce. When one views the ethnographic and trade information in the map and interprets them from a relative topological point of view we can see this as

23688-500: The large-scale maps of that era as a general basis for their later, more generalized works. They were taught more to draft and engrave medium-scale geographic maps of states, continents etc., or their parts (e.g. the map of upper and middle- Italy in 1847 for Stielers Handatlas , which was based on Attilio Zuccagni-Orlandini 's 1844 topographic map in nearly 100 sheets), small-scale generalised school maps, and especially applied geography and cartography as shown in their collaboration on

23876-451: The last flight of the Apollo capsule. Flown in 1975, a U.S. Apollo spacecraft docked with a Soviet Soyuz capsule. During the 1960s, NASA started its space science and interplanetary probe program. The Mariner program was its flagship program, launching probes to Venus , Mars , and Mercury in the 1960s. The Jet Propulsion Laboratory was the lead NASA center for robotic interplanetary exploration, making significant discoveries about

24064-511: The last of 3 weeks visiting the US, Dr. Isaac I. Hayes disputed the hypothesis of Petermann's land tongue stretching from Greenland to the Bering Sea , though he agreed that the Arctic Ocean would possibly have open water. The Northwest Passage indeed proved to be challenging. Only in 1904 did Roald Amundsen achieve its navigation. As to the Northeast Passage , Nordenskiöld's trip to

24252-484: The long-range exploration of space; and none will be so difficult or expensive to accomplish. Kennedy gave his " We choose to go to the Moon " speech the next year, on September   12, 1962 at Rice University , where he addressed the nation hoping to reinforce public support for the Apollo program. Despite attacks on the goal of landing astronauts on the Moon from the former president Dwight Eisenhower and 1964 presidential candidate Barry Goldwater , President Kennedy

24440-434: The majority of the International Space Station, Russia, Canada, Japan, and the European Space Agency all contributed components. Despite NASA's insistence that costs would be kept at a budget of $ 17.4, they kept rising and NASA had to transfer funds from other programs to keep the International Space Station solvent. Ultimately, the total cost of the station was $ 150 billion, with the United States paying for two-thirds.Following

24628-429: The map are the blank areas, hoping that they would stimulate explorers to go on expeditions to find out what new things there could be. But it was also a case of marketing PGM, as shown in the memoire that accompanied the map, where Petermann wrote: "The basic idea of our map was to give travellers a sure support for the choice of their routes and guarantee the direction of the explorations, to resolve doubts and stimulate

24816-405: The maps, drawn when he was 16, shows South America, and was later published in the journal which was to carry his name. Berghaus recognized the quality of Petermann's work, and therewith his potential and soon took him in as a foster-son. As Berghaus already had a large family to feed, however, he requested an annual subsidy of 60 thaler from the king to support Petermann, which was granted. During

25004-542: The military. The Mercury 7 astronauts included three Air Force pilots, three Navy aviators, and one Marine Corps pilot. On May 5, 1961, Alan Shepard became the first American to enter space, performing a suborbital spaceflight in the Freedom 7 . This flight occurred less than a month after the Soviet Yuri Gagarin became the first human in space, executing a full orbital spaceflight. NASA's first orbital spaceflight

25192-493: The monthly Mittheilungen aus Justus Perthes Geographischer Anstalt über wichtige neue Erforschungen auf dem Gesamtgebiet der Geographie von Dr. A. Petermann (PGM) (Communications from the Justus Perthes Geographical Institute concerning important new studies in the whole field of geography, by Dr. A. Petermann). These were to be published in 'casual issues'. Their relation to several of the Perthes atlases

25380-609: The moon of Enceladus , which could harbor life. Finally launched in 2006, the New Horizons mission was the first spacecraft to visit Pluto and the Kuiper Belt . Beyond interplanetary probes, NASA has launched many space telescopes . Launched in the 1960s, the Orbiting Astronomical Observatory were NASA's first orbital telescopes, providing ultraviolet, gamma-ray, x-ray, and infrared observations. NASA launched

25568-405: The new discoveries). In 1871/72 he published the eight-sheet map as Specialkarte von Australien in 8 Blättern in Ergänzungsheft 29 (volume VI) and 30 (volume VII). It is a superb effort to compile all available knowledge in a colored map-image that measures 194x118 cm altogether, and it reminds us of the ten-sheet map of Africa of 1863. Being Petermann he would have liked to have accompanied it with

25756-471: The next forty years, NACA would conduct aeronautical research in support of the U.S. Air Force , U.S. Army , U.S. Navy , and the civil aviation sector. After the end of World War II , NACA became interested in the possibilities of guided missiles and supersonic aircraft, developing and testing the Bell X-1 in a joint program with the U.S. Air Force . NACA's interest in space grew out of its rocketry program at

25944-431: The older one, though only six years lay between the two. Petermann kept his promise, made in the preface of the first issue of PGM, when he was responsible for the new edition of Stieler's Hand-Atlas. He also had a weakness for Australia. Up to his death he published some 48 maps concerning exploration in (parts of) Australia, though hardly any of the expeditions bore any German influence. In 1866, when he gave an account of

26132-474: The polar regions, but none appeared in the supplements of that period. He actually started to push his interest in this subject in the 1865 issue of PGM and with the publication of supplement 16 ( Ergänzungsband IV ) in 1865. In the PGM-issue he recites the correspondence he has with the Royal Geographical Society (RGS) concerning the proposal of capt. Sherard Osborn (1822–1875) to send another English expedition to

26320-489: The programmed issues to be discussed was the issue of guidelines for the use of a homogeneous meteorological logbook for the German merchant navy. In later years the maps in PGM made much use of the data thus gathered. Petermann jealously reported on the marine surveys in Britain and America, which were realized with governmental support, and he dearly wished such was possible in other nations, especially Germany. Furthermore, he pointed out that Germany had much to gain by exploring

26508-724: The publication of the National Atlas of General Geography , which contained 4 maps by Berghaus. Though Berghaus deemed the commercial and scientific climate in England not ready for scientific maps Johnston persisted in wanting to publish a translation of the Physikalischer Atlas, on which he requested aid from Berghaus. With a letter of recommendation by von Humboldt in October 1844, Heinrich 'Henry' Lange joined Johnston in Edinburgh for this purpose. Petermann stayed behind in Gotha and became

26696-558: The radiation levels on Mars were equal to those on the International Space Station , greatly increasing the possibility of Human exploration, and observed the key chemical ingredients for life to occur. In 2013, the Mars Atmosphere and Volatile Evolution ( MAVEN ) mission observed the Martian upper atmosphere and space environment and in 2018, the Interior exploration using Seismic Investigations Geodesy, and Heat Transport ( InSight ) studied

26884-514: The receipts and expenditures in several issues of PGM. In 1865, Otto Volger of the FDH ( Freies Deutsches Hochstift für Wissenschaft, Künste und allgemeine Bildung , founded in 1859) organised the 'Allgemeine Deutsche Versammlung von Freunden der Erdkunde' (General German Assembly of Friends of Geography). During this two-day meeting Georg von Neumayer stressed the fact that Germany needed a German maritime institute to be independent of other nations. One of

27072-535: The representation of the Gabon countries, which show interpretations by August Petermann, Thomas E. Bowdich , William D. Cooley, Heinrich Kiepert , Paul Belloni du Chaillu and Heinrich Barth . NASA The National Aeronautics and Space Administration ( NASA / ˈ n æ s ə / ) is an independent agency of the U.S. federal government responsible for the civil space program , aeronautics research, and space research. Established in 1958 , it succeeded

27260-425: The results of geographic exploration. In an age hungry for adventure, but not yet totally scientifically literate, this was the best way to attract the largest possible group of interested readers. The maps not only supplemented several of the Perthes atlases, but were also used as a forum to elaborate on new themes, thus widening the thematic scope of cartography. He expresses his emphasis on maps anew when he writes in

27448-491: The route of the 1868 German expedition is not engraved in the image. Petermann still believed however, that Greenland stretched far into the Polar region. The text in the map reads: 'Unerforscht, wahrscheinlich Land oder Inseln (Petermann's Hypothese)' [unexplored, probably land or islands (Petermann's hypothesis)]. In the case of the polar regions, Petermann's point of view deviated from most contemporary views. While many, especially

27636-489: The same atlas. John Bartholomew became Petermann's student in Gotha in 1855 until he was recalled to his father's firm in 1856. The German school of cartography was pre-eminent, and four generations of Bartholomews widened their knowledge by studying with the German masters. John George's son Ian studied in Leipzig (1907–08) with Oswald Winkel. His grandson John Christopher carried on the tradition, studying with Eduard Imhof ,

27824-409: The same copperplate, but with both routes highlighted and another title. Sheets 2–14 of Barth's work are route maps on the scale 1:800,000 and 1:1,000,000. In 1855 PGM gives only a summary of the routes of the first half of the total tour, on scale of 1:2,100,000, with added profiles along the borders that do not appear on the detail maps. This was a corrected issue of a map first published in London. In

28012-502: The satellites were repaired and relaunched. Despite ushering in a new era of spaceflight, where NASA was contracting launch services to commercial companies, the Space Shuttle was criticized for not being as reusable and cost-effective as advertised. In 1986, Challenger disaster on the STS-51L mission resulted in the loss of the spacecraft and all seven astronauts on launch, grounding the entire space shuttle fleet for 36 months and forced

28200-502: The school itself had but few students, its residency in Potsdam, connected by rail to Berlin, and the fame of Berghaus attracted many geographers (e.g. Alexander von Humboldt , Carl Ritter and Zeune), cartographers and explorers. Petermann spoke highly of his encounters with von Humboldt and drew several maps for his Atlas von Asien , on which the rendering of the Asiatic mountain chains was of

28388-557: The second edition of The physical atlas of natural phenomena (1856). Maps in the Journal (Proceedings) of the Royal Geographical Society can be viewed through JSTOR . See footnote "From the early 1850s, Petermann maintained private and business contacts with the two Gotha publishers Wilhelm and Bernhardt Perthes, and in June 1853 he actually spent a short time in Gotha.". Financial difficulties and several other factors prompted him to accept

28576-641: The separation of dark and regular matter during galactic collisions. Finally, the Spitzer Space Telescope is an infrared telescope launched in 2003 from a Delta II rocket. It is in a trailing orbit around the Sun, following the Earth and discovered the existence of brown dwarf stars . Other telescopes, such as the Cosmic Background Explorer and the Wilkinson Microwave Anisotropy Probe , provided evidence to support

28764-477: The session of the Royal Geographical Society of London on 22 November 1852, would be persuaded to know that the natural beauty of the Arctic regions cannot be surpassed by any other in the world." Though the accompanying map shows his theory concerning an extended Greenland he doesn't write about this, but mainly about his errouneous theory concerning the behavior of the Gulf Stream. Supplement IV gives an overview of

28952-458: The setback caused by the Apollo   1 fire, which killed three astronauts, the program proceeded. Apollo   8 was the first crewed spacecraft to leave low Earth orbit and the first human spaceflight to reach the Moon . The crew orbited the Moon ten times on December   24 and   25, 1968, and then traveled safely back to Earth . The three Apollo   8 astronauts— Frank Borman , James Lovell , and William Anders —were

29140-433: The sledges usually used by the Americans and the British. He must have been convinced that the central Arctic contained vast expanses of open water and land, the latter presumably extensions of Greenland and Spitsbergen. Though the routes in the Antarctic map have been engraved, they are not highlighted in color. Instead Petermann has colored the polygons that encompass the areas covered by the several explorers. This highlights

29328-422: The sources, for that might give inaccurate measurements, so many of his maps show large blank spaces. How right he was in this respect was demonstrated in 1911 when Julien Thoulet drafted bathymetric maps for the territory of France. In these four maps he draws hypothetical isobaths, which are based on respectively 15, 31, 154, and 308 altitude measurements per 153,821 square miles (398,390 km ) for France and

29516-438: The space agency where he would serve as the director of the Apollo program. Development of the Saturn   V rocket was led by Wernher von Braun and his team at the Marshall Space Flight Center , derived from the Army Ballistic Missile Agency's original Saturn   I . The Apollo spacecraft was designed and built by North American Aviation , while the Apollo Lunar Module was designed and built by Grumman . To develop

29704-421: The space shuttle be retired. In 2006, the Space Shuttle returned to flight, conducting several mission to service the Hubble Space Telescope , but was retired following the STS-135 resupply mission to the International Space Station in 2011. NASA never gave up on the idea of a space station after Skylab's reentry in 1979. The agency began lobbying politicians to support building a larger space station as soon as

29892-427: The space station spelled an end to the program. In 2003, a second space shuttle was destroyed when the Columbia was destroyed upon reentry during the STS-107 mission, resulting in the loss of the spacecraft and all seven astronauts. This accident marked the beginning of the retiring of the Space Shuttle program, with President George W. Bush directing that upon the completion of the International Space Station,

30080-413: The spaceflight skills and equipment required for a lunar mission, NASA initiated Project Gemini . Using a modified Air Force Titan   II launch vehicle, the Gemini capsule could hold two astronauts for flights of over two weeks. Gemini pioneered the use of fuel cells instead of batteries, and conducted the first American spacewalks and rendezvous operations . The Ranger Program was started in

30268-566: The split. The Peterman glacier has shrunk several kilometers in length since 2002. The development can be seen on NASA Satellite Imagery. A new crack was seen in 2017. As of May 2023, the major Greenland Glacier is melting away which could add to the rise in sea-level. The glaciers grounding line can shift significantly with the tides. The glacier is not growing and claims that it is have been attributed to climate change deniers. August Heinrich Petermann Augustus Heinrich Petermann (18 April 1822 – 25 September 1878)

30456-448: The start, the journal contained small messages concerning developments in geography under the heading Geographische Notizen/Monatsbericht (1855–....). Some of these were concerned with recently published literature, mainly book citations. In 1860 Petermann decided that these should be listed in a more structured way, the latter temporarily as Geographischer Literatur Bericht für ****(1886–1909), maybe inspired by Kroner's literature lists in

30644-436: The strength of the missionaries' reports. As their mission was focused on people and not on the natural environment this kind of information was of great importance to them. But geometrically their information could not be trusted, in part because most of their information was based on verbal reports of the native tribes. At other times he depicted maps of the same area from several authors together in one supplement map to show

30832-407: The understanding about potential pathways of relative warmer water influx towards Greenland's many outlet glaciers. A program involving both seismic data acquisition, multibeam mapping, coring and seismic reflection profiling was conducted in order to study the past behaviour of the Petermann Glacier. In August 2010, a giant iceberg measuring 260 square kilometres (100 sq mi) broke off from

31020-492: The unexplored area clearly, even though it is blank. But Petermann is definitely more interested in having the Germans explore the Arctic than the Antarctic, presumably because the costs of an Arctic expedition can be met more easily than those of an Antarctic one. The more detailed map of Spitsbergen not only shows the Swedish surveys of 1861 to 1864, but also the presence of coal fields, coastal areas with driftwood, and areas where reindeer can normally be found. Petermann's last map

31208-463: The vast oceans would only vaguely approximate the true relief of the ocean floors. Petermann must have had the same idea intuitively for his exploratory maps. He was keen, however, to introduce spot heights and spot depths in the maps he drafted so that others could benefit from them. Having understood well from his teacher, Heinrich Berghaus, the merit of the metric scale he introduced the representative fraction as map scale, without discarding, however,

31396-415: The verbal better known or local scale . The popular acceptance of the metric system and Greenwich as prime meridian was slower in the uptake. Only with the ninth edition of Stieler's Hand-Atlas (1900–1905) was this process completed. In 1870, Petermann advocated the use of a red and blue color scheme for temperature maps of the oceans. Although the number of projection methods increased at a reasonable rate,

31584-399: Was Venus , sharing many similar characteristics to Earth. First visited by American Mariner 2 spacecraft, Venus was observed to be a hot and inhospitable planet. Follow-on missions included the Pioneer Venus project in the 1970s and Magellan , which performed radar mapping of Venus' surface in the 1980s and 1990s. Future missions were flybys of Venus, on their way to other destinations in

31772-455: Was a German cartographer . Petermann was born in Bleicherode , Germany . When he was 14 years old, he started grammar school in the nearby town of Nordhausen . Despite family pressures to become a clergyman , he pursued his passion for cartography instead. Heinrich Berghaus , with the support of Alexander von Humboldt , started the 'Geographische Kunstschule' (Geographical School of Art) in 1839 in Potsdam , close to Berlin , following

31960-467: Was a physician, who learned the geographic trade in practice) wrote many articles about geodesy and surveying , they rarely got involved in other technical and theoretical cartographic issues. Petermann concerned himself much more with printing technology, especially colour-lithography. Although they produced many color maps in this way in the 1870s, more and more maps returned to hand coloring, for it then became cheaper than lithography. According to Stams,

32148-463: Was able to previously accomplish. NASA launched its first commercial satellites on the STS-5 mission and in 1984, the STS-41-C mission conducted the world's first on-orbit satellite servicing mission when the Challenger captured and repaired the malfunctioning Solar Maximum Mission satellite. It also had the capability to return malfunctioning satellite to Earth, like it did with the Palapa B2 and Westar 6 satellites. Once returned to Earth,

32336-424: Was able to protect NASA's growing budget, of which 50% went directly to human spaceflight and it was later estimated that, at its height, 5% of Americans worked on some aspect of the Apollo program. Mirroring the Department of Defense's program management concept using redundant systems in building the first intercontinental ballistic missiles, NASA requested the Air Force assign Major General Samuel C. Phillips to

32524-555: Was aimed at surveying, drafting and engraving. Berghaus's pupils learned only the rudiments of surveying, even less than he himself had learned: their work in this area can be seen in the plan of Potsdam ( Neüester Plan von der Königlichen Residenzstadt Potsdam / nach trigonometrischen Vermessungen, so wie geo- und hydrometrischen Aufnahmen ausgearbeitet in der Geographischen Kunstschule zu Potsdam unter der Leitung ihres Direktors, des Professors Dr. Heinrich Berghaus. 1845). They were not topographers and only used topography as published in

32712-415: Was also a concern with sharing sensitive space technologies with the Europeans, which had the potential to dilute America's technical lead. Ultimately, an international agreement to develop the Space Station Freedom program would be signed with thirteen countries in 1985, including the European Space Agency member states, Canada , and Japan . Despite its status as the first international space program,

32900-531: Was also keen to use physical characteristics as background for thematic maps , an idea followed by his pupils. When Herbert Louis demanded in 1960 that the terrain underlying thematic maps should indicate elevations, hydrological networks, settlements and traffic roads, he cited Petermann as the first cartographer who used a terrain map as basis for population maps. By using hachuring as a basis for his Karte des Österreichischen Kaiserstaates zur Übersicht der Dichtigkeit der Bevölkerung nach dem Census von 1857 (Map of

33088-419: Was at least quite up to date on many affairs to do with geography and cartography, for Berghaus had large collections of maps, books and notes to draw on. During and after their training, students were obliged to take part in most of the school's enterprises. In the years 1839–1848, the school produced maps for Stieler's school atlas, and Berghaus's Physikalischer Atlas , school atlases, the Atlas von Asien ,

33276-445: Was conducted by John Glenn on February 20, 1962, in the Friendship 7 , making three full orbits before reentering. Glenn had to fly parts of his final two orbits manually due to an autopilot malfunction. The sixth and final Mercury mission was flown by Gordon Cooper in May 1963, performing 22 orbits over 34 hours in the Faith 7 . The Mercury Program was wildly recognized as a resounding success, achieving its objectives to orbit

33464-442: Was launched in 1990 on STS-31 from the Discovery and could view galaxies 15 billion light years away. A major defect in the telescope's mirror could have crippled the program, had NASA not used computer enhancement to compensate for the imperfection and launched five Space Shuttle servicing flights to replace the damaged components. The Compton Gamma Ray Observatory was launched from the Atlantis on STS-37 in 1991, discovering

33652-410: Was not appointed head of the Perthes establishment Petermann could only guide the other skills available. Fortunately he could call on cartographers and engravers who had developed their skills through long experience with men like Adolf Stieler , Stülpnagel, Heinrich Berghaus , Emil von Sydow , etc., as well as new cartographers like Carl Vogel and Hermann Berghaus . According to Hermann Wagner it

33840-452: Was not felt wise to have any of these employees appointed as head of the establishment. Instead the firm was led by Adolf Müller, not a cartographer, but an economic manager. The cartographers Petermann trained included Bruno Hassenstein (1839–1902), Hermann Habenicht (1844–1917, who from 1897 onwards trained Hermann Haack, the 20th-century editor of PGM), Ernst Debes (1840–1923. He could have come to rival Carl Vogel, but in 1868 he left

34028-438: Was only sharpened when paired with his updating of Stieler's Hand-Atlas. In stressing the geographic nature of cartography, he showed himself more a Humboldtian than a follower of Ritter's political-historical school. M. Linke et al. wrote in 1986: "There seems to be no doubt that Petermann’s work contributed to the high standards of British cartography during these years". T.W. Freeman has noted that "Fine maps had been produced in

34216-578: Was plainly expounded in the preface to the first issue of 1855: "Our 'Communications' will differ from all similar publications in that they will summarise and graphically illustrate the results of new geographic explorations in precisely executed and carefully detailed maps. Every issue of our periodical will therefore include one or more map supplements, and their design will guarantee a continuous and easily accessible supplement in easy-to-manage form with special regard for those who own Stielers Hand-Atlas, Berghaus's Physical Atlas, and other map publications of

34404-400: Was refused a position equal to Petermann he left Perthes and started to work for Brockhaus in Leipzig. When Petermann went to the Gotha Institute part of the original plan was that he would revive the Geographisches Jahrbuch (Geographical Yearbook), which Heinrich Berghaus had edited from 1850 to 1852. At the suggestion of the manager Adolf Müller (1820–1880) it was decided instead to publish

34592-407: Was right in hypothesizing that the warm Gulf Stream complemented the cold Labrador Stream and that the warm stream extended far north of Spitsbergen and Nova Zembla, his thesis that it warmed the Arctic needed serious revision. Although he thought it to be a deep stream, he overestimated the effect of the warmth from that depth on surface ice east of Svalbard. On the other hand, he was wrong about

34780-408: Was supported by the British government, was to negotiate trade treaties with the rulers of the middle Sudan. Petermann, supported by Carl Ritter and Robert Bunsen, pleaded with the British government to let Heinrich Barth and Adolf Overweg join up with Richardson's expedition to assure that geographical and scientific aspects which they might encounter were taken care of. When still affiliated with

34968-405: Was the first to include them in geographic maps), more accurate engraving and better coloring, for under his directions the maps of the Stieler became more uniform in expression. In this they were also guided by the more than consistent work of Vogel, and Von Sydow's critical remarks concerning the advantages and disadvantages of certain styles in his Kartographischen Standpunkt Europas . Petermann

35156-448: Was tracked by the Canadian Ice Service for over a year as it travelled out into Nares Strait and south through Baffin Bay before losing contact with the remnants in Frobisher Bay in July 2009. On July 15/16 2012, a 130-square-kilometre (50 sq mi) piece (about twice the area of Manhattan ), calved from the northern tip of the glacier. A long crack at the site had been observed by NASA satellites for several years prior to

35344-446: Was well earned, for few slavishly copied what explorers or other experts had sketched. German geographers, like Hermann Wagner (1840–1929), claimed that in other geographical journals explorer's maps were just copied instead of having them evaluated by cartographers first. Maps based on recent exploration reports were always, when possible, complemented with route maps from previous expeditions. He did not like to infer or extrapolate from
