61-482: Parkes Observatory is a radio astronomy observatory, located 20 kilometres (12 mi) north of the town of Parkes, New South Wales , Australia. It hosts Murriyang , the 64 m CSIRO Parkes Radio Telescope also known as " The Dish ", along with two smaller radio telescopes . The 64 m dish was one of several radio antennae used to receive live television images of the Apollo 11 Moon landing. Its scientific contributions over
122-399: A depth charge , with the surrounding water concentrating the force of the explosion on the target. A crucial innovation was to spin the bomb. The spin direction determined the number of bounces/range of the bomb. A change to backspin (rather than top-spin), was put forward by another Vickers designer, George Edwards, based on his knowledge as a cricketer. Spin caused the bomb to trail behind
183-429: A laser guiding system. This primary-secondary approach was designed by Barnes Wallis . The focus cabin is located at the focus of the parabolic dish, supported by three struts 27 metres (89 ft) above the dish. The cabin contains multiple radio and microwave detectors, which can be switched into the focus beam for different science observations. These include: The 18-metre (59 ft) "Kennedy Dish" antenna
244-572: A marine engineer and in 1922 he took a degree in engineering via the University of London External Programme . Wallis left J. Samuel White's in 1913 when an opportunity arose for him as an aircraft designer , at first working on airships and later aeroplanes . He joined Vickers – later part of Vickers-Armstrongs and then part of the British Aircraft Corporation – and worked for them until his retirement in 1971. There he worked on
305-562: A search for radio signals from extraterrestrial technologies for the heavily funded project Breakthrough Listen . The principal role of the Parkes Telescope in the program will be to conduct a survey of the Milky Way galactic plane over 1.2 to 1.5 GHz and a targeted search of approximately 1000 nearby stars over the frequency range 0.7 to 4 GHz. During the Apollo missions to the Moon ,
366-460: A son of Marie Stopes . His son Christopher Loudon Wallis was instrumental in the restoration of the watermill and its building on the Stanway Estate near Cheltenham , Gloucestershire. Wallis was a vegetarian and an advocate of animal rights . He became a vegetarian at age 73. In the 1955 film The Dam Busters , Wallis was played by Michael Redgrave . Wallis's daughter Elisabeth played
427-459: A supersonic development of Wild Goose, designed in the mid-1950s, which could have been developed for either military or civil applications. Both Wild Goose and Swallow were flight tested as large (30 ft span) flying scale models, based at Predannack in Cornwall. However, despite promising wind tunnel and model work, his designs were not adopted. Government funding for "Swallow" was cancelled in
488-583: A technologically advanced nation". On Monday, 31 October 2011, Google Australia replaced its logo with a Google Doodle in honour of Parkes Observatory's 50th anniversary. The Parkes Radio Telescope was added to the National Heritage List in 2020. In November 2020, in NAIDOC Week , the Observatory's three telescopes were given Wiradjuri names. The main telescope ("The Dish") is Murriyang , after
549-777: Is frequently operated together with the Australia Telescope Compact Array at Narrabri , the ASKAP array in Western Australia , and a single dish at Mopra , telescopes operated by the University of Tasmania as well as telescopes from New Zealand, South Africa and Asia to form a Very Long Baseline Interferometry (VLBI) array . 1960s 1990s 2000s Fast radio bursts were discovered in 2007 when Duncan Lorimer of West Virginia University assigned his student David Narkevic to look through archival data recorded in 2001 by
610-557: Is now buried at the local St. Lawrence Church together with his wife. His epitaph in Latin reads "Spernit Humum Fugiente Penna" ( Severed from the earth with fleeting wing ), a quotation from Horace Ode III.2 . They had four children – Barnes (1926–2008), Mary (1927–2019), Elisabeth (b. 1933) and Christopher (1935–2006) – and also adopted Molly's sister's children John and Robert McCormick when their parents were killed in an air raid. His daughter Mary Eyre Wallis later married Harry Stopes-Roe ,

The Science Museum at Wroughton , near Swindon, holds 105 boxes of papers of Barnes Wallis. The papers comprise design notes, photographs, calculations, correspondence and reports relating to Wallis's work on airships, including the R100; geodetic construction of aircraft;
793-703: The CSIRO 's Radiophysics Laboratory. During the Second World War , he had worked on radar development in the United States and had made connections in its scientific community. Calling on this old boy network , he persuaded two philanthropic organisations, the Carnegie Corporation and the Rockefeller Foundation , to fund half the cost of the telescope. It was this recognition and key financial support from
854-774: The TFX programme and the General Dynamics F-111 . In the UK, Vickers submitted a wing-controlled aerodyne for specification OR.346 for a reconnaissance/strike-fighter-bomber, effectively the TSR-2 specification with added fighter capability. When Maurice Brennan left Vickers for Folland he worked on the FO.147, a variable-sweep development of the Gnat lightweight fighter-trainer, offering both tailed and tailless options. Wallis's ideas were ultimately passed over in
915-818: The V-3 supergun bunker, submarine pens and other reinforced structures, large civil constructions such as viaducts and bridges, as well as the German battleship Tirpitz . They were the forerunners of modern bunker-busting bombs . Having been dispersed with the Design Office from Brooklands to the nearby Burhill Golf Club in Hersham , after the Vickers factory was badly bombed in September 1940, Wallis returned to Brooklands in November 1945 as head of
976-618: The Wellesley , the Wellington and the later Warwick and Windsor all employed Wallis's geodetic design in the fuselage and wing structures. The Wellington had one of the most robust airframes ever developed, and pictures of its skeleton largely shot away, but still sound enough to bring its crew home safely, are still impressive. The geodetic construction offered a light and strong airframe (compared to conventional designs), with clearly defined space within for fuel tanks, payload and so on. However
1037-497: The earthquake bomb , including designs such as the Tallboy and Grand Slam bombs. Barnes Wallis was born in Ripley , Derbyshire , to general practitioner Charles George Wallis (1859–1945) and his wife Edith Eyre (1859–1911), daughter of Rev. John Ashby. The Wallis family subsequently moved to New Cross , south London, living in "straitened, genteel circumstances" after Charles Wallis
1098-509: The swing-wing functional. He developed the wing-controlled aerodyne , a concept for a tailless aeroplane controlled entirely by wing movement with no separate control surfaces. His " Wild Goose ", designed in the late 1940s, was intended to use laminar flow , and alongside it he also worked on the Green Lizard cruise missile and the Heston JC.9 manned experimental aeroplane. The " Swallow " was
1159-496: The 1950s and 1960s, including research into supersonic aerodynamics that contributed to the design of Concorde , before finally closing by 1980. This unique structure was restored at Brooklands Museum thanks to a grant from the AIM-Biffa fund in 2013 and was officially reopened by Mary Stopes-Roe , Barnes Wallis's daughter, on 13 March 2014. Although he did not invent the concept, Wallis did much pioneering engineering work to make
1220-523: The 64-metre (210 ft) dish at Parkes. Since they started the spacewalk early, the Moon was only just above the horizon and below the visibility of the main Parkes receiver. Although they were able to pick up a quality signal from the off axis receiver, the international broadcast alternated between signals from Goldstone and Honeysuckle Creek, the latter of which ultimately broadcast Neil Armstrong 's first steps on
1281-600: The Admiralty's first rigid airship HMA No. 9r under H. B. Pratt , helping to nurse it though its political stop-go career and protracted development. The first airship of his own design, the R80 , incorporated many technical innovations and flew in 1920. By the time he came to design the R100 , the airship for which he is best known, in 1930 he had developed his revolutionary geodetic construction (also known as geodesic), which he applied to
SECTION 20
#17328593526291342-489: The Moon worldwide. A little under nine minutes into the broadcast, the Moon rose far enough to be picked by the main antenna and the international broadcast switched to the Parkes signal. The quality of the TV pictures from Parkes was so superior that NASA stayed with Parkes as the source of the TV for the remainder of the 2.5-hour broadcast. In the lead up to the landing wind gusts greater than 100 km/h (62 mph) were hitting
1403-692: The Parkes Observatory was used to relay communication and telemetry signals to NASA , providing coverage for when the Moon was on the Australian side of the Earth. The telescope also played a role in relaying data from the NASA Galileo mission to Jupiter that required radio-telescope support due to the use of its backup telemetry subsystem as the principal means to relay science data. The observatory has remained involved in tracking numerous space missions up to
1464-727: The Parkes radio dish. Analysis of the survey data found a 30- jansky dispersed burst which occurred on 24 July 2001, less than 5 milliseconds in duration, located 3° from the Small Magellanic Cloud . At the time it was theorised FRBs might be signals from another galaxy, emissions from neutron stars or black holes. More recent results confirm that magnetars , a kind of highly magnetised neutron star, may be one source of fast radio bursts. In 1998 Parkes telescope began detecting fast radio bursts and similar looking signals named perytons . Perytons were thought to be of terrestrial origin, such as interference from lightning strikes. In 2015 it
1525-531: The Parkes telescope, and the telescope operated outside safety limits throughout the moonwalk. In 2012 the observatory received special signals from the Mars rover Opportunity (MER-B), to simulate the Curiosity rover UHF radio. This helped prepare for the then upcoming Curiosity (MSL) landing in early August—it successfully touched down on 6 August 2012. The Parkes Observatory Visitors Centre allows visitors to view
1586-816: The R100 was broken up following the crash near Beauvais in northern France of its "sister" ship, the R101 (which was designed and built by a team from the Government's Air Ministry). The later destruction of the Hindenburg led to the abandonment of airships as a mode of mass transport. By the time of the R101 crash, Wallis had moved to the Vickers aircraft factory at the Brooklands motor circuit and aerodrome between Byfleet and Weybridge in Surrey . The prewar aircraft designs of Rex Pierson ,

The inner part of the dish is solid aluminium and the outer area a fine aluminium mesh, creating its distinctive two-tone appearance. In the early 1970s the outer mesh panels were replaced by perforated aluminium panels. The inner smooth plated surface
1708-501: The UK in favour of the fixed-wing BAC TSR-2 and Concorde. He was critical of both, believing that swing-wing designs would have been more appropriate. In the mid-1960s, TSR-2 was ignominiously scrapped in favour of the American F-111, which had swing-wings influenced by Wallis's work at NASA, although this order was also subsequently cancelled. In the 1950s, Wallis developed an experimental rocket-propelled torpedo codenamed HEYDAY. It
1769-405: The United States that persuaded Australian prime minister, Robert Menzies , to agree to fund the rest of the project. The Parkes site was chosen in 1956, as it was accessible, but far enough from Sydney to have clear skies. Additionally the mayor Ces Moon and landowner Australia James Helm were both enthusiastic about the project. The success of the Parkes telescope led NASA to copy features of
1830-539: The United States, and suggested that Britain could dominate air travel by developing a small supersonic airliner capable of short take-off and landing . Wallis became a Fellow of the Royal Society in 1945, was knighted in 1968, and received an Honorary Doctorate from Heriot-Watt University in 1969. Wallis was awarded £10,000 for his war work from the Royal Commission on Awards to Inventors . His grief at

In 1995 the radio telescope was declared a National Engineering Landmark by Engineers Australia . The nomination cited its status as the largest southern hemisphere radio telescope, elegant structure, with features mimicked by later Deep Space Network telescopes, scientific discoveries and social importance through "enhancing [Australia's] image as
2318-643: The dropping aircraft (decreasing the chance of that aircraft being damaged by the force of the explosion below), increased the range of the bomb, and also prevented it from moving away from the target wall as it sank. After some initial scepticism, the Air Force accepted Wallis's bouncing bomb (codenamed Upkeep ) for attacks on the Möhne , Eder and Sorpe dams in the Ruhr area . The raid on these dams in May 1943 (Operation Chastise )
2379-480: The enemy's power supplies, he wrote (as Axiom 3): "If their destruction or paralysis can be accomplished they offer a means of rendering the enemy utterly incapable of continuing to prosecute the war". As a means to do this, he proposed huge bombs that could concentrate their force and destroy targets which were otherwise unlikely to be affected. Wallis's first super-large bomb design came out at some ten tons, far more than any current bomber could carry. Rather than drop
2440-477: The gasbag framing. He also pioneered, along with John Edwin Temple, the use of light alloy and production engineering in the structural design of the R100.

2562-401: The idea, this led him to suggest a plane that could carry it – the " Victory Bomber ". Early in 1942, Wallis began experimenting with skipping marbles over water tanks in his garden, leading to his April 1942 paper " Spherical Bomb – Surface Torpedo". The idea was that a bomb could skip over the water surface, avoiding torpedo nets , and sink directly next to a battleship or dam wall as
2623-547: The ideas he suggested are the same as or closely related to the final design, including the idea of supporting the dish at its centre, the geodetic structure of the dish and the master equatorial control system. Unhappy with the direction it had taken, Wallis left the project halfway into the design study and refused to accept his £1,000 consultant's fee. In the 1960s, Wallis also proposed using large cargo submarines to transport oil and other goods, thus avoiding surface weather conditions. Moreover, Wallis's calculations indicated,

He advocated nuclear-powered cargo submarines as a means of making Britain immune to future embargoes, and to make it a global trading power. He complained of the loss of aircraft design to
2745-400: The lives of his test pilots. His designs were extensively tested in model form, and consequently he became a pioneer in the remote control of aircraft. A massive 19,533 square feet (1,814.7 m ) Stratosphere Chamber (which was the world's largest facility of its type) was designed and built beside the clubhouse by 1948. It became the focus for much R&D work under Wallis's direction in
2806-466: The loss of so many airmen in the dams raid was such that Wallis donated the entire sum to his alma mater Christ's Hospital School in 1951 to allow them to set up the RAF Foundationers' Trust, assisting the children of RAF personnel killed or injured in action to attend the school. Around this time he also became an almoner of Christ's Hospital. When he retired from aeronautical work in 1957, he
2867-554: The power requirements for an underwater vessel were lower than for a comparable conventional ship and they could be made to travel at a much higher speed. He also proposed a novel hull structure which would have allowed greater depths to be reached, and the use of gas turbine engines in a submarine, using liquid oxygen. In the end, nothing came of Wallis's submarine ideas. During the 1960s and into his retirement, he developed ideas for an "all-speed" aircraft, capable of efficient flight at all speed ranges from subsonic to hypersonic . In
2928-548: The present day, including: The CSIRO has made several documentaries on this observatory, with some of these documentaries being posted to YouTube. When Buzz Aldrin switched on the TV camera on the Lunar Module , three tracking antennas received the signals simultaneously.

2989-670: The round of cuts following the Sandys Defence White Paper in 1957, although Vickers continued model trials with some support from the RAE. An attempt to gain American funding led Wallis to initiate a joint NASA -Vickers study. NASA found aerodynamic problems with the Swallow and, informed also by their work on the Bell X-5 , settled for a conventional tail which would eventually lead in turn to
3050-409: The same as the 5-tonne " blockbuster " bomb, which was a conventional blast bomb. Although there was still no aircraft capable of lifting these two bombs to their optimal release altitude, they could be dropped from a lower height, entering the earth at supersonic speed and penetrating to a depth of 20 metres before exploding. They were used on strategic German targets such as V-2 rocket launch sites,
3111-634: The same era contributed to Hydrogen line and OH investigations. As a stand-alone antenna it was used in studying the Magellanic Stream . It was used as an uplink antenna in the Apollo program, as the larger Parkes telescope is receive-only. It is preserved by the Australia Telescope National Facility. The observatory is a part of the Australia Telescope National Facility network of radio telescopes. The 64-metre (210 ft) dish

#17328593526293172-401: The technique was not easily transferred to other aircraft manufacturers, nor was Vickers able to build other designs in factories tooled for geodetic work. After the outbreak of the Second World War in Europe in 1939, Wallis saw a need for strategic bombing to destroy the enemy's ability to wage war and he wrote a paper titled "A Note on a Method of Attacking the Axis Powers ". Referring to
3233-524: Was 34, and her father forbade them from courting. However, he allowed Wallis to assist Molly with her mathematics courses by correspondence, and they wrote some 250 letters, enlivening them with fictional characters such as "Duke Delta X". The letters gradually became personal, and Wallis proposed marriage on her 20th birthday. They were married on 23 April 1925, and remained so for 54 years until his death in 1979. For 49 years, from 1930 until his death, Wallis lived with his family in Effingham, Surrey , and he
3294-423: Was an English engineer and inventor . He is best known for inventing the bouncing bomb used by the Royal Air Force in Operation Chastise (the "Dambusters" raid) to attack the dams of the Ruhr Valley during World War II . The raid was the subject of the 1955 film The Dam Busters , in which Wallis was played by Michael Redgrave . Among his other inventions were his version of the geodetic airframe and
3355-409: Was appointed Treasurer and Chairman of the Council of Almoners of Christ's Hospital, holding the post of Treasurer for nearly 13 years. During this time he oversaw its major reconstruction. Wallis was an active member of the Royal Air Forces Association , the charity that supports the RAF community. In April 1922, Wallis met his cousin-in-law, Molly Bloxam, at a family tea party. She was 17 and he

He was educated at Christ's Hospital in Horsham and Haberdashers' Aske's Hatcham Boys' Grammar School in southeast London, leaving school at seventeen to start work in January 1905 at Thames Engineering Works at Blackheath , southeast London. He subsequently changed his apprenticeship to J. Samuel White 's, the shipbuilders based at Cowes on the Isle of Wight . He originally trained as

When the microwave oven door was opened, 1.4 GHz microwaves from the magnetron shutdown phase were able to escape. Subsequent tests revealed that a peryton can be generated at 1.4 GHz when a microwave oven door is opened prematurely and the telescope is at an appropriate relative angle. The telescope has been contracted to be used in

The Möhne and Eder dams were successfully breached, causing damage to German factories and disrupting hydro-electric power . After the success of the bouncing bomb, Wallis was able to return to his huge bombs, producing first the Tallboy (6 tonnes) and then the Grand Slam (10 tonnes) deep-penetration earthquake bombs . These were not

Mounted on rails and powered by a tractor engine to allow the distance between the antenna and the main dish to be easily varied, it was used as an interferometer with the main dish. Phase instability due to an exposed cable meant that its pointing ability was diminished, but it was able to be used for identifying size and brightness distributions. In 1968 it successfully proved that Radio galaxy lobes were not expanding, and in
