98-490: Polaris Dawn was a private crewed spaceflight operated by SpaceX on behalf of Shift4 CEO Jared Isaacman , the first of three planned missions in the Polaris program . Launched 10 September 2024 as the 14th crewed orbital flight of a Crew Dragon spacecraft, Isaacman and his crew of three — Scott Poteet , Sarah Gillis and Anna Menon — flew in an elliptic orbit that took them 1,400 kilometers (870 mi) away from Earth,
196-617: A government agency , such as NASA or ESA . During the early decades of the Space Age , the government space agencies of the Soviet Union and United States pioneered space technology in collaboration with affiliated design bureaus in the USSR and private companies in the US. They entirely funded both the development of new spaceflight technologies and the operational costs of spaceflight . Following
294-429: A commercial entity. The history of full private space transportation includes early efforts by German company OTRAG in the 20th century. Founded in 1975 as the first private company to attempt to launch a private spacecraft, testing of its OTRAG rocket began in 1977. The history also covers numerous modern orbital and suborbital launch systems in the 21st century. More recent commercial spaceflight projects include
392-500: A component of US space law for over 25 years, and during this time, "has never been invoked in any commercial launch mishap". In 1992, a Resurs-500 capsule containing gifts was launched from Plesetsk Cosmodrome in a private spaceflight called Europe-America 500 . The flight was conceived by the Russian Foundation for Social Inventions and TsSKB-Progress , a Russian rocket-building company, to increase trade between Russia and
490-538: A crew gantry access arm and white room to allow for crew and cargo ingress to the vehicle. The existing Space Shuttle evacuation slide-wire basket system was re-purposed to provide a safe emergency egress for the Dragon crew in the event of an emergency on the pad that does not necessitate using the Crew Dragon 's launch abort system". In 2019, SpaceX began substantial modification to LC 39A in order to begin work on phase 1 of
588-546: A few hundred dollars per kilogram as the technology of a second private spaceflight startup of ~2000 comes into service. The first privately funded rocket to reach the boundary of space, the Kármán line , (although not orbit) was Conestoga I , which was launched by Space Services Inc. on a suborbital flight to 309 kilometres (192 mi) altitude on 9 September 1982. In October 1995, their first (and only) attempt at an orbital launch, Conestoga 1620, failed to achieve orbit due to
686-523: A flexible launch window for the Polaris Dawn mission, allowing them to select a time with minimal debris in the targeted orbit. The Dragon capsule was initially placed in an elliptic orbit with an apogee of 1,200 kilometers (750 mi), passing through the South Atlantic Anomaly at a low altitude of 190 kilometers (120 mi). This exposed the crew to the equivalent radiation of three months on
784-436: A formal solicitation for proposals for commercial use of the pad. There were two competing bids for the commercial use of the launch complex. SpaceX submitted a bid for exclusive use of the launch complex, while Jeff Bezos ' Blue Origin submitted a bid for shared non-exclusive use of the complex, so that the launchpad would handle multiple vehicles, and costs could be shared over the long-term. One potential shared user in
882-486: A guidance system failure. On April 5, 1990, Orbital Sciences Corporation 's Pegasus , an air launched rocket, was the first launch vehicle fully developed by a private company to reach orbit. In the early 2000s, several public-private corporate partnerships were established in the United States to privately develop spaceflight technology. Several purely private initiatives have shown interest in private endeavors to
980-546: A large vacuum chamber . The crew also spent two days in a chamber at the Johnson Space Center to validate their pre-breathing protocol and on another occasion also tested their EVA suits in full vacuum in the chamber. The mission also saw the first crewed operational test of Dragon laser interlink communication via Starlink . SpaceX hopes that the technology can decrease communication latency and increase data bandwidth for human spaceflight. Within an hour of launch,
1078-465: A mission between NASA , SpaceX , and Intuitive Machines . This event marked the first successful landing of a privately owned spacecraft on the Moon and the United States' first lunar landing in over 50 years and the first lander to do so with cryogenic propellants . Today many commercial space transportation companies offer launch services to satellite companies and government space organizations around
SECTION 10
#17328481209981176-564: A new clause to NASA's mission statement : Yet one of NASA's early actions was to effectively prevent private space flight through a large amount of regulation. From the beginning, though, this met significant opposition not only by the private sector, but in Congress. In 1962, Congress passed its first law pushing back the prohibition on private involvement in space, the Communications Satellite Act of 1962 . While largely focusing on
1274-555: A private company had begun transporting cargo to and from the International Space Station , while a second private company was scheduled to begin making deliveries in 2013, ushering in a time of regular private space cargo delivery to and return from the government-owned space facility in low Earth orbit (LEO). In this new paradigm for LEO cargo transport, the government contracts for and pays for cargo services on substantially privately developed space vehicles rather than
1372-704: A private flight to the Moon, from the FAA's Office of Commercial Space Transportation. On 30 May 2020, Crew Dragon Demo-2 operated by SpaceX became the first crewed mission to the International Space Station in the Commercial Crew Program . After 2015, European-based private small-lift launch vehicle development got underway, particularly in Germany, Italy, and the United Kingdom, but "France has largely been left out of this new commercial launch industry". In 2021,
1470-476: A record, flying further from Earth than any women before them. On flight day two, the Dragon's apogee was lowered to its "cruising orbit" of 730 kilometers (450 mi) while the crew prepared their EVA suits and conducted experiments. On this day, the crew also contributed to breaking the record for the most people (19) simultaneously in space, set after the Soyuz MS-26 mission launched on 11 September along with
1568-689: A similar model of space technology development, the European Space Agency was formed in 1975. Arianespace , born out of ESA's independent spaceflight efforts, became the world's first commercial launch service provider in the early 1980s. Subsequently, large defense contractors began to develop and operate space launch systems , which were derived from government rockets. Private spaceflight in Earth orbit includes communications satellites , satellite television , satellite radio , astronaut transport and sub-orbital and orbital space tourism . In
1666-459: A total of 72 MN (16,000,000 lbf) liftoff thrust when departing 39A. In August 2019, SpaceX submitted an Environmental Assessment for the Starship launch system at Kennedy Space Center. This document included plans for the construction of additional structures at LC-39A to support Starship launches, including a dedicated pad, liquid methane tanks, and a Landing Zone. These are separate from
1764-620: Is flaring back into life, and it's not massive institutions such as NASA that are in the running. The old view that human space flight is so complex, difficult and expensive that only huge government agencies could hope to accomplish it is being disproved by a new breed of flamboyant space privateers, who are planning to send humans out beyond the Earth's orbit for the first time since 1972," particularly noting projects underway by Mars One , Inspiration Mars Foundation , Bigelow Aerospace and SpaceX . The Commercial Space Launch Act of 1984 required encouragement of commercial space ventures, adding
1862-630: Is marketed via Starsem . The Sea Launch project flew the Ukrainian Zenit rocket . In 2003, Arianespace joined with Boeing Launch Services and Mitsubishi Heavy Industries to create the Launch Services Alliance . In 2005, continued weak commercial demand for EELV launches drove Lockheed Martin and Boeing to propose a joint venture called the United Launch Alliance to service the United States government launch market. Since
1960-556: The Commercial Space Launch Act . This enabled an American industry of private operators of expendable launch systems . Prior to the signing of this law, all commercial satellite launches in the United States were restricted by Federal regulation to NASA's Space Shuttle . On 11 February 1988, the Presidential Directive declared that the government should purchase commercially available space goods and services to
2058-706: The Delta IV and Atlas V EELVs remain in active service. Commercial launches outnumbered government launches at the Eastern Range in 1997. The Commercial Space Act was passed in 1998 and implements many of the provisions of the Launch Services Purchase Act of 1990 . Nonetheless, until 2004 NASA kept private space flight effectively illegal. But that year, the Commercial Space Launch Amendments Act of 2004 required that NASA and

#17328481209982156-467: The Draco thrusters fired, propelling them to their highest apogee of the mission, 1,400 kilometers (870 mi) away from Earth, the highest orbit of the planet ever flown by a crewed spacecraft, breaking the record set by Gemini 11 , and the farthest anyone has been from Earth since the 1972 Apollo 17 mission of NASA's Apollo program . Because these earlier missions had all-male crews, Menon and Gillis broke
2254-501: The Federal Aviation Administration legalise private space flight. The 2004 Act also specified a "learning period" which restricted the ability of the FAA to enact regulations regarding the safety of people who might actually fly on commercial spacecraft through 2012, ostensibly because spaceflight participants would share the risk of flight through informed consent procedures of human spaceflight risks, while requiring
2352-453: The Government of France announced a plan to fund the "France-based rocket firm ArianeGroup to develop a new small-lift rocket called Maïa by the year 2026," which would be a government-funded but commercially developed rocket. On 22 February 2024, Intuitive Machine's private Odysseus successfully landed on the Moon after taking off on a SpaceX Falcon 9 liftoff on 15 February 2024 in
2450-658: The International Space Station . In 2015, SpaceX built the Horizontal Integration Facility (HIF) just outside the perimeter of the existing launch pad in order to house both the Falcon 9 and the Falcon Heavy rockets, and their associated hardware and payloads, during preparation for flight. Both types of launch vehicles are transported from the HIF to the launch pad aboard a Transporter Erector (TE) which rides on rails up
2548-705: The Rotating Service Structure (RSS) and removed it beginning in February 2016. NASA removed the Orbiter Servicing Arm—with intent to use the space later to build a museum—and the white room by which astronauts entered the Space Shuttle. SpaceX indicated in late 2014 that additional levels to the FSS would not be added in the near term. SpaceX planned to eventually add at least two additional levels to
2646-451: The U.S. civilian space program and Soviet space program were operated using mainly military pilots as astronauts . During this period, no commercial space launches were available to private operators, and no private organization was able to offer space launches. Eventually, private organizations were able to both offer and purchase space launches, thus beginning the period of private spaceflight. The first phase of private space operation
2744-537: The inner Solar System . In 2006, NASA initiated a program to purchase commercial space transport to carry cargo to the International Space Station , while funding a portion of the development of new technology in a public-private partnership . In May 2015, the Japanese legislature considered legislation to allow private company spaceflight initiatives in Japan. In 2016, the United States granted its first clearance for
2842-413: The 1980s, various private initiatives have started up to pursue the private use of space . Traditional costs to launch anything to space have been high—on the order of tens of thousands of US dollars per kilogram—but by 2020, costs on the order of a few thousand dollars per kilogram are being seen from one private launch provider that was an early 2000s startup, with the cost projected to fall to less than
2940-821: The 1990s–2000s. From 2000 through the end of 2015, a total of US$ 13.3 billion of investment finance was invested in the space sector, with US$ 2.9 billion of that being venture capital . In 2015, venture capital firms invested US$ 1.8 billion in private spaceflight companies, more than they had in the previous 15 years combined. As of October 2015 , the largest and most active investors in space were Lux Capital , Bessemer Venture Partners , Khosla Ventures , Founders Fund , RRE Ventures and Draper Fisher Jurvetson . Increasing interest by investors in economically driven spaceflight had begun to appear by 2016, and some space ventures had to turn away investor funding. CBInsights in August 2016 published that funding to space startups
3038-464: The Blue Origin plan was United Launch Alliance . Prior to the end of the bid period, and prior to any public announcement by NASA of the results of the process, Blue Origin filed a protest with the U.S. General Accounting Office (GAO) "over what it says is a plan by NASA to award an exclusive commercial lease to SpaceX for use of mothballed space shuttle launch pad 39A". NASA had planned to complete

3136-619: The Cape to adjacent Merritt Island to the north and west. First named Launch Complex 39C, Launch Complex 39A was designed to handle launches of the Saturn V rocket, the largest and most powerful launch vehicle, which would propel the Apollo spacecraft to the Moon. The first launch from Launch Complex 39A occurred in 1967 with the first Saturn V launch, which carried the uncrewed Apollo 4 spacecraft. The second uncrewed launch, Apollo 6 , also used Pad 39A. With
3234-611: The Constellation program was cancelled. Talks for use of the pad were underway between NASA and Space Florida —the State of Florida 's economic development agency —as early as 2011, but no deal materialized by 2012, and NASA then pursued other options for removing the pad from the federal government inventory. By early 2013, NASA publicly announced that it would allow commercial launch providers to lease LC-39A, and followed that, in May 2013, with
3332-506: The Crew Dragon lacks an airlock , the entire capsule was depressurized during the EVA, exposing all crew members to the vacuum of space, though only two partially exited the spacecraft. Depressurization of the capsule took about 30 minutes. Isaacman went first, spending seven minutes and 56 seconds outside. Gillis went next, spending seven minutes and 15 seconds outside. From hatch open to hatch close
3430-408: The EVA suits for this mission based on the intravehicular activity (IVA) suits typically worn during launch and landing. The EVA suits are designed to keep astronauts safe in the vacuum of space while also being comfortable and flexible enough for launch and landing, eliminating the need for separate IVA suits. Flame-resistant, stretching fabric and soft joints provide mobility, while boots are made from
3528-401: The EVA took about 26 minutes and 40 seconds. During the EVA, Isaacman and Gillis performed several tests of their suit mobility including trials of hand/body control, vertical movement, and using a foot restraint, only their lower legs were still inside the spacecraft. Gillis, at 30 years old, became the youngest person to date to participate in a spacewalk. At the end of the final day on orbit,

Since 1995 Khrunichev's Proton rocket has been marketed through International Launch Services , while the Soyuz rocket
4410-453: The United States, the FAA has created a new certification called Commercial Astronaut , a new occupation. In the 2000s, entrepreneurs began designing—and by the 2010s, deploying—space systems competitive to the governmental systems of the early decades of the space age. These new offerings have brought about significant market competition in space launch services after 2010 that had not been present previously, principally through
4508-493: The advent of the Space Shuttle program in the early 1980s, the original structure of the launch pads were remodeled for the needs of the Space Shuttle. The first usage of Pad 39A for the Space Shuttle came in 1979, when Enterprise was used to check the facilities prior to the first operational launch. Since then, Pad 39A hosted all Space Shuttle launches until January 1986, when Space Shuttle Challenger would become

The right does not extend to biological life , so anything that is alive may not be exploited commercially. The Act further asserts that "the United States does not [(by this Act)] assert sovereignty , or sovereign or exclusive rights or jurisdiction over, or the ownership of, any celestial body ". The SPACE Act includes
4900-584: The comparatively limited pool of the 1990s. For example, as of June 2013 and in the United States alone, ten billionaires had made "serious investments in private spaceflight activities" at six companies, including Stratolaunch Systems , Planetary Resources , Blue Origin , Virgin Galactic , SpaceX , and Bigelow Aerospace . The ten investors were Paul Allen , Larry Page , Eric Schmidt , Ram Shriram , Charles Simonyi , Ross Perot Jr. , Jeff Bezos , Richard Branson , Elon Musk , and Robert Bigelow . At

The capsule splashed down in the Gulf of Mexico near Florida's Dry Tortugas islands on 15 September 2024 at 07:36:54 UTC (3:36:54 am EDT, local time at the landing site). The landing site was one of two new options SpaceX added for this mission as it planned for challenging weather conditions. Isaacman, 41, headed
5390-446: The early 2020s some of these investments have paid off, with Musk's SpaceX coming to dominate the launch market in mass to orbit and with a $ 100 billion valuation. Other companies such as Bigelow Aerospace though have collapsed and left the market. Some aerospace startups, such as Rocket Lab , have gone public via special-purpose acquisition company , but their SPAC values have been affected by market volatility. Some investors see
5488-544: The exception of Apollo 10 , which used Pad 39B (due to the "all-up" testing resulting in a 2-month turnaround period), all crewed Apollo-Saturn V launches, commencing with Apollo 8 , used Pad 39A. Launch Complex 39A was used for the uncrewed launch of the Skylab space station on May 14, 1973. This used a modified Saturn V originally built for the cancelled Apollo 18 mission. The subsequent Skylab crewed missions launched from Launch Complex 39B using Saturn IB launch vehicles. With

On February 6, 2018, Pad 39A hosted the successful liftoff of the Falcon Heavy on its maiden launch , carrying Elon Musk's Tesla Roadster car to space; and
7154-430: The mid-launch explosion/loss of Challenger came the suspension of the government -operated shuttle flights, allowing the formation of a commercial launch industry. On 4 July 1982, the Reagan administration released National Security Decision Directive Number 42 which officially set its goal to expand United States private-sector investment and involvement in civil space and space-related activities. On 16 May 1983,
7252-440: The mission as Commander, with primary spacecraft operation duties. Retired Air Force fighter pilot Scott Poteet, 50, served as spacecraft pilot, assisting Isaacman with spacecraft operation duties. Completing the crew were SpaceX employees Sarah Gillis, 30, and Anna Menon, 38, as Mission Specialists. Gillis is the company's senior space operations engineer who leads crew training for private spaceflight missions, she joined Isaacman on
7350-535: The mission was part of the program, including extravehicular activity (EVA) spacesuits , intersatellite laser communication links between the Dragon spacecraft and the Starlink constellation, and accommodation for the lack of an airlock in the Dragon capsule. Originally slated to fly in late 2022, the program suffered delays over the design of the EVA spacesuits and technical problems with SpaceX testing inter-satellite laser communication links. By October 2022,
7448-408: The nine crew members of the International Space Station and the three crew members of China's Tiangong space station . Flight day three was dedicated to the first-ever extravehicular activity (EVA) on a commercial spaceflight mission. After extensive preparations, all four crew members donned their EVA suits, which are pressurized with 100% oxygen at 5.1 pounds per square inch (35 kPa). Since
7546-499: The other and how they would manage the facility". On December 13, 2013, NASA announced that it had selected SpaceX as the new commercial tenant. On April 14, 2014, SpaceX signed a lease agreement that gave it a 20-year exclusive lease on LC-39A. SpaceX planned to launch their launch vehicles from the pad and build a new hangar nearby. Elon Musk , CEO of SpaceX, stated that he wanted to shift most of SpaceX's NASA launches to LC-39A, including commercial cargo and crew missions to
7644-581: The reduction of the cost of space launch and the availability of more space launch capacity . Private spaceflight accomplishments to date include flying suborbital spaceplanes ( SpaceShipOne and SpaceShipTwo ), launching orbital rockets , flying two orbital expandable test modules ( Genesis I and II ). On the opposite, launching astronauts to the International Space Station and certain satellite launches are performed on behalf of and financed by government agencies. Planned private spaceflights beyond Earth orbit include personal spaceflights around
7742-480: The same thermal material used on Falcon 9's interstage and Dragon's trunk. Compared to the IVA suits, thermal management has been improved and the helmet has received thermal insulation and an anti-fog treatment. A heads-up display was added to the helmet to provide real-time information on suit metrics during the spacewalk. An umbilical provided life support for these suits, similar to early Gemini suits , as opposed to
7840-536: The satellites of its namesake, this was described by both the law's opponents and advocates of private space, as the first step on the road to privatisation. While launch vehicles were originally bought from private contractors, from the beginning of the Shuttle program until the Space Shuttle Challenger disaster in 1986, NASA attempted to position its shuttle as the sole legal space launch option. But with
7938-573: The self-contained EMUs used on the ISS . This mission broke the record for the most people in the vacuum of space at once, set at three during Apollo 9 and later repeated just five more times on Apollo 15 , 16 , 17 , Skylab 2 , and STS-49 . Due to the unique depressurization protocol, the crew conducted research on decompression sickness and spaceflight associated neuro-ocular syndrome (SANS). To validate their procedures, SpaceX subjected Resilience to multiple cycles of venting and repressurization in
8036-400: The spacewalk. Menon is a lead space operations engineer and mission director for the company, who acted as onboard medical officer for the mission. She has six years of experience as a biomedical flight controller at NASA , where she oversaw International Space Station operations, including several spacewalks. To minimize the risk of micrometeorite impacts, SpaceX mission controllers had
8134-413: The start of the private space era it was not yet clear to what extent these entrepreneurs see "legitimate business opportunity, [for example], space tourism and other commercial activities in space, or [are] wealthy men seeking the exclusivity that space offers innovators and investors." There has been speculation as to whether these investments are a "gamble", and whether they will prove lucrative. As of
8232-745: The suborbital flights of Virgin Galactic and Blue Origin , the orbital flights of SpaceX and other COTS participants. Development of alternatives to government-provided space launch services began in earnest in the 2000s. Private interests began funding limited development programs, but the US government later sponsored a series of programs to incentivize and encourage private companies to begin offering both cargo, and later, crew space transportation services. Lower prices for launch services after 2010, and published prices for standard launch services, have brought about significant space launch market competition that had not been present previously. By 2012,
8330-400: The three crew members of China's Tiangong space station . After a mission lasting nearly five days, the crew safely splashed down in the Gulf of Mexico on 15 September. The Polaris program was announced by Jared Isaacman in February 2022, five months after the first all-private astronaut mission, Inspiration4 , which was also backed by Isaacman. Development of technologies necessary for
8428-432: The traditional spaceflight industry as ripe for disruption , with "a 100-fold improvement [relatively straightforward and] a thousand-fold improvement [possible]". Between 2005 and 2015, there was US$ 10 billion of private capital invested in the space sector, most of it in the United States. This liberalized private space sector investments beginning in the 1980s, with additional legislative reforms in
8526-551: The trench in place. The damage had been exacerbated by the fact that hydrochloric acid is an exhaust by-product of the solid rocket boosters. Just as for the first 24 shuttle flights, LC-39A supported the final shuttle flights, starting with STS-117 in June 2007 and ending with the retirement of the Shuttle fleet in July 2011. In total, Pad 39A hosted 94 launches from 1967 to 2011, including 12 Saturn V rockets and 82 space shuttles. Prior to
8624-403: The world. In 2005, there were 18 total commercial launches and 37 non-commercial launches. Russia flew 44% of commercial orbital launches, while Europe had 28% and the United States had 6%. China's first private launch, a suborbital flight by OneSpace , took place in May 2018. In recent years, the funding to support private spaceflight has begun to be raised from a larger pool of sources than
8722-414: The youngest person to date to participate in a spacewalk. During the spacewalk, a new record was set for the number of people (four) simultaneously exposed to the vacuum of space. The crew also contributed to breaking the record for the most people (19) simultaneously in orbit, set after the Soyuz MS-26 mission launched on 11 September along with the nine crew members of the International Space Station and
8820-520: Was "in a slump", although the number of space investment deals per quarter had gone from 2 or 3 in 2012 to 14 by 2015. In 2017, CB Insights ranked the most active space tech investors, ranked from highest to lowest, were Space Angels Networks, Founders Fund, RRE Ventures, Data Collective, Bessemer, Lux Capital, Alphabet , Tencent Holdings , and Rothenberg Ventures . In June 2019, Miriam Kramer of Axios wrote that private spaceflight companies and investors were poised to capitalize on NASA's plan to open up
8918-506: Was 31 July 2024. The mission was delayed again following the failure of a Falcon 9 rocket's upper stage on 12 July 2024. After SpaceX addressed the cause of the mishap, SpaceX's Dragon mission management director Sarah Walker announced in a 26 July news conference that Polaris Dawn would launch "in late summer" after the Crew-9 mission for NASA, which had been scheduled to launch no earlier than 18 August before its delay. SpaceX then said that it
9016-484: Was launched on November 15, 2020 . SpaceX launched the IM-1 robotic lander for NASA's Commercial Lunar Payload Services program on 15 February 2024, returning the pad to Lunar missions since the end of the Apollo program. The Starlink Group 6-56 mission launched on 8 May 2024, and was the Falcon 9's 83rd launch from LC-39A. That milestone made the rocket family the pad leader for launches from that launch complex, surpassing
9114-527: Was notable as it marked the first time that SpaceX was able to successfully soft-land all three of the reusable booster stages , which were to be refurbished for future launches. The Crew Dragon Demo-2 test flight launched with astronauts Bob Behnken and Doug Hurley from Launch Complex 39A on 30 May 2020, and docked to pressurised mating adapter PMA-2 on the Harmony module of the ISS on 31 May 2020. The first operational Commercial Crew mission Crew-1
9212-483: Was scrubbed due to poor predicted weather during the recovery period five days after launch. Because the mission would not rendezvous with the International Space Station and had limited life support consumables, the capsule had to be able to splash down as scheduled, which made favorable weather conditions a must. The launch was further delayed because of poor weather causing a lack of favorable launch and return conditions. As of 8 September 2024, SpaceX said it
9310-431: Was targeting a 26 August launch date on 7 August. SpaceX pushed the launch date back a day to 27 August in order to allow "additional time for teams to complete preflight" checkouts. The flight was further delayed by weather at the landing site and was scheduled for the early morning of September 6, 2024. A number of design changes were made to Dragon capsule Resilience before the launch. Several modifications were made to
9408-473: Was targeting no earlier than (NET) 10 September for launch, with weather conditions being 40% favorable for liftoff and splashdown. Polaris Dawn successfully launched on 10 September 2024 at 09:23:49 UTC (5:23:49 am EDT , local time at the launch site). Note: times are local to the launch site ( Eastern Daylight Time ). Private spaceflight Private spaceflight refers to spaceflight developments that are not conducted by
9506-496: Was the launch of the first commercial communications satellites . The U.S. Communications Satellite Act of 1962 allowed commercial consortia owning and operating their own satellites, although these were still deployed on state-owned launch vehicles. In 1980, the European Space Agency created Arianespace , a company to be operated commercially after initial hardware and launch facilities were developed with government funding. Arianespace has since launched numerous satellites as
9604-422: Was underway to support an annual launch cadence of 40+ Starship launches. The first SpaceX launch from pad 39A was SpaceX CRS-10 on February 19, 2017, using a Falcon 9 launch vehicle; it was the company's 10th cargo resupply mission to the International Space Station, and the first uncrewed launch from 39A since Skylab. While Cape Canaveral Space Launch Complex 40 (SLC-40) was undergoing reconstruction after
