9375-402: 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
9500-448: The first pharaohs." The science objectives of the mission are: Telescopic observations have helped define the orbit of 101955 Bennu , a near-Earth object (NEO) with a mean diameter in the range of 480 to 511 m (1,575 to 1,677 ft). It completes an orbit of the Sun every 436.604 days (1.2 years). This orbit takes it close to the Earth every six years. Although the orbit
9625-439: The form of clay . While researchers suspect that Bennu was too small to host water, the hydroxyl groups may have come from water present in its parent body before Bennu split off. OSIRIS-REx entered orbit around Bennu on 31 December 2018 at about 1.75 km (1.09 mi) to start its extensive remote mapping and sensing campaign for the selection of a sample site. This is the closest distance that any spacecraft has orbited
9750-577: The formation of Earth. Organic molecules, such as amino acids , have previously been found in meteorite and comet samples, indicating that some ingredients necessary for life can be naturally synthesized in outer space. The cost of the OSIRIS-REx mission is approximately US$ 800 million, not including the Atlas ;V launch vehicle, which is about US$ 183.5 million. The OSIRIS-APEX extended mission costs an additional US$ 200 million. It
9875-550: The four Great Observatories , and associated programs. The Launch Services Program oversees launch operations for its uncrewed launches . NASA traces its roots to the National Advisory Committee for Aeronautics (NACA). Despite being the birthplace of aviation, by 1914 the United States recognized that it was far behind Europe in aviation capability. Determined to regain American leadership in aviation,
10000-451: 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
10125-546: The latches – which keep the collector head in place – are well secured. Following the test, the mission team received telemetry confirming that the head was properly secured in the Sample-Return Capsule. Thereafter, on 28 October 2020, two mechanical parts on the TAGSAM arm were disconnected – these are the tube that carried the nitrogen gas to the TAGSAM head during sample collection and the TAGSAM arm itself. Over
10250-434: 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
10375-424: The mission team to select the site from which to take a sample of at least 60 g (2.1 oz) of material of the asteroid's surface. Then a close approach (without landing) was carried out to allow extension of a robotic arm to gather the sample. Following the successful collection of material (121.6 grams), the sample was returned to Earth in a 46 kg (101 lb) capsule similar to that which returned
10500-634: 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
10625-400: The new name suggests, its next target will be the near-Earth asteroid (and potentially hazardous object ) 99942 Apophis . Apophis will make an extremely close pass to the Earth on 13 April 2029, although there is no chance for an impact during this or any subsequent flybys in the near future. Observations of Apophis will commence on 8 April 2029, and a few days later, on 21 April, OSIRIS-APEX
10750-429: The next several hours, the mission team commanded the spacecraft to cut the tube that stirred up the sample through the TAGSAM head during sample collection, and separate the collector head from the TAGSAM arm. Once the team confirmed these activities were done, it commanded the spacecraft on 28 October 2020, to close and seal the Sample-Return Capsule, the final step of the sample stowage process of Bennu's samples. To seal
10875-533: The operation required as the spacecraft approached Bennu, searching for natural satellites and other potential hazards. On 12 February 2017, while 673 × 10 ^ km (418 × 10 ^ mi) from Jupiter , the PolyCam instrument aboard OSIRIS-REx successfully imaged the giant planet and three of its moons, Callisto , Io , and Ganymede . OSIRIS-REx flew by Earth on 22 September 2017. On 3 December 2018, NASA confirmed that OSIRIS-REx had matched
11000-495: The performance of Mini-TES in the dusty surface environment of Mars, OTES was designed to be resilient to extreme dust contamination on the optical elements. The Regolith X-ray Imaging Spectrometer (REXIS) provided an X-ray spectroscopy map of Bennu to map element abundances. REXIS was a collaborative development by four groups within Massachusetts Institute of Technology (MIT) and Harvard University , with
11125-532: The potential to involve more than 100 students throughout the process. REXIS was based on flight heritage hardware, thereby minimizing elements of technical risk, schedule risk, and cost risk. REXIS is a coded aperture soft X-ray (0.3–7.5 keV) telescope that images X-ray fluorescence line emission produced by the absorption of solar X-rays and the solar wind by elements in the regolith of Bennu leading to local X-ray emissions. Images were formed with 21 arcminute resolution (4.3 m spatial resolution at
11250-411: The probe then executed a back-away maneuver to depart safely. The plan was then for OSIRIS-REx to perform a braking maneuver a few days later to halt the drift away from the asteroid in case it was necessary to return for another sampling attempt. It would then take images of the TAGSAM head to verify a sample had been acquired. If a sample was acquired, the spacecraft would rotate about the short axis of
11375-570: 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
11500-597: The receiver telescope limiting the effects of background solar radiation. Each pulse provides target range, azimuth, elevation, received intensity and a time-tag. OLA was funded by the Canadian Space Agency (CSA) and was built by MDA at Brampton , Ontario , Canada. OLA was delivered for integration with the spacecraft on 17 November 2015. The lead instrument scientist of OLA is Michael Daly from York University . The sample-return system, called Touch-And-Go Sample Acquisition Mechanism (TAGSAM), consists of
11625-457: The recovered capsule was opened to reveal a "first look" at the asteroid sample contents. Further looks were reported on 13 December 2023 and revealed organic molecules and unknown materials that require study to determine their composition. Some damaged fasteners prevented immediate opening, but, after three months, on 13 January 2024, NASA reported fully opening the recovered container. In total, 121.6 g (4.29 oz) of asteroidal material
11750-517: The regolith of asteroid Bennu while Apophis Explorer corresponds to the study of Apophis asteroid. When its heritage concept was proposed in the Discovery Program in 2004, it was called only OSIRIS, with REx for "Regolith Explorer" used descriptively rather than as part of the name. The asteroid for the second mission is named after the ancient Egyptian god Apophis , who was associated with chaos and destruction. The mission name itself
11875-456: The respective projects: Each of these words was chosen to represent an aspect of this mission. For example, the S, for security means the security of Earth from impact by hazardous near-Earth objects (NEOs). Specifically it refers to better understanding the Yarkovsky effect , which can alter the trajectories of orbiting bodies. Regolith Explorer means that the mission will study the texture, morphology, geochemistry , and spectral properties of
12000-434: The sample arm to determine sample mass by measuring momentum of inertia and determine if it was in excess of the required 60 g (2.1 oz). Both the braking and rotation maneuvers were canceled when images of the sample container clearly showed a large excess of material was collected, some of which was able to escape through the container's seal because some material had jammed the mechanism open. The collected material
12125-473: The sample through the flaps, NASA canceled the previously planned spinning maneuver meant to determine the mass of the sample as well as a navigational braking maneuver, and decided to stow the sample on 27 October 2020 rather than 2 November 2020 as originally planned, which was completed successfully. The collector head was observed hovering over the Sample Return Capsule (SRC) after
12250-460: The sampler had made contact. The spacecraft touched down within 92 cm (36 in) of the target location. A sample of the asteroid which was estimated to weigh at least 2 ounces (57 grams) was collected by OSIRIS-REx following the touch down. After imaging the TAGSAM head, NASA concluded that there were rocks wedged in the mylar flap meant to keep the sample inside, causing the sample to slowly escape into space. In order to prevent further loss of
12375-576: The samples of Comet 81P/Wild on the space probe Stardust . The return trip to Earth was shorter than the outbound trip. The capsule landed by parachute at the Utah Test and Training Range on September 24, 2023 and was transported to the Johnson Space Center for processing in a dedicated research facility. The launch was on 8 September 2016 at 23:05 UTC on a United Launch Alliance Atlas V 411 from Cape Canaveral , Space Launch Complex 41 . The 411 rocket configuration consists of
12500-507: 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
12625-676: 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
12750-560: 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
12875-549: 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
13000-481: 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,
13125-553: The spacecraft and provides mission operations. The science team includes members from the United States, Canada, France, Germany, the United Kingdom, and Italy. After traveling for approximately two years, the spacecraft rendezvoused with asteroid 101955 Bennu in December ;2018, and began 505 days of surface mapping at a distance of approximately 5 km (3.1 mi). Results of that mapping were used by
13250-399: The spacecraft carries a suite of instruments to image and analyze the asteroid on many wavelengths, and retrieve a physical sample to return to Earth. The Planetary Society coordinated a campaign to invite interested persons to have their names or artwork on the mission's spirit of exploration saved on a microchip now carried in the spacecraft. The OSIRIS-REx Camera Suite (OCAMS) consists of
13375-467: The speed and orbit of Bennu at a distance of about 19 km (12 mi), effectively reaching the asteroid. OSIRIS-REx performed closer passes of the Bennu surface, initially at about 6.5 km (4.0 mi) through December to further refine the shape and orbit of Bennu. Preliminary spectroscopic surveys of the asteroid's surface by the OSIRIS-REx spacecraft detected the presence of hydrated minerals in
13500-515: The surface before performing a back-away burn. A second rehearsal was successfully completed on 11 August 2020, bringing OSIRIS-REx down to 40 m (130 ft) from the surface. This was the final rehearsal before the sample collection scheduled for 20 October 2020, at 22:13 UTC. At 22:13 UTC , on 20 October 2020, OSIRIS-REx successfully touched down on Bennu at a distance of 200 million miles (320 million kilometers) from Earth. NASA confirmed via images taken during sampling that
13625-493: The surface of Bennu, a total of at least 133 events/asteroid pixel/energy band were expected under 2 keV; enough to obtain significant constraints on element abundances at scales larger than 10 m. On 11 November 2019, while observing the asteroid with REXIS, university students and researchers involved in the mission unexpectedly discovered an X-ray burst from a black hole named MAXI J0637-430 located 30,000 light-years away. The OSIRIS-REx Laser Altimeter (OLA)
13750-475: The surface to find a suitable site from which to extract a sample. On 20 October 2020, OSIRIS-REx touched down on Bennu and successfully collected a sample. OSIRIS-REx left Bennu on 10 May 2021 and returned its sample to Earth on 24 September 2023, subsequently starting its extended mission to study 99942 Apophis , where it will arrive in April 2029. Bennu was chosen as the target of study because it
13875-579: The use of fuel cells instead of batteries, and conducted the first American spacewalks and rendezvous operations . The Ranger Program was started in the 1950s as a response to Soviet lunar exploration, however most missions ended in failure. The Lunar Orbiter program had greater success, mapping the surface in preparation for Apollo landings and measured Selenography , conducted meteoroid detection, and measured radiation levels. The Surveyor program conducted uncrewed lunar landings and takeoffs, as well as taking surface and regolith observations. Despite

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
14250-489: Was a joint NASA–U.S. Air Force program, with 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
14375-454: Was a reference to the god Osiris . Dante Lauretta, deputy PI of the mission, was called "a mythology buff" by the mission PI Michael Drake: "he was doodling on a pad and trying to capture the principal themes of what we are trying to do with this mission study life origins, identify resources, planetary security in the form of asteroid deflection and he realized he got the name of Osiris out of that, an ancient god of Egypt who may have been one of
14500-683: 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,
14625-545: 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,
14750-399: Was detected using accelerometers, and the impact force was dissipated by a spring in the TAGSAM arm. Upon surface contact by the TAGSAM instrument, a burst of nitrogen gas was released to blow regolith particles smaller than 2 cm (0.8 in) into the sampler head at the end of the robotic arm. A five-second timer limited the collection time to mitigate the chance of a collision, and
14875-403: Was interleaved with the event data to account for Bennu rotation. Images were reconstructed on the ground after downlink of the event list. Images were formed simultaneously in 16 energy bands centered on the dominant lines of abundant surface elements from O-K (0.5 keV) to Fe-Kß (7 keV) as well the representative continuum. During orbital phase 5B, a 21-day orbit 700 m from
15000-497: 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
15125-484: Was near the equator. NASA planned to perform the first sampling in late August 2020; NASA's originally planned Touch-and-Go (TAG) sample collection was scheduled for 25 August 2020, but was rescheduled for 20 October 2020, at 22:13 UTC. On 15 April 2020, the first sample collection rehearsal was successfully performed at the Nightingale sample site. The exercise took OSIRIS-REx as close as 65 m (213 ft) from
15250-431: Was recovered from the sample container. The samples became available to the world’s scientists for research by request on 1 April, 2024. On 15 May 2024, an overview of preliminary analytical studies on the returned samples was reported. On 25 April 2022, NASA confirmed that the mission would be extended. After dropping off its sample to Earth on 24 September 2023, the mission became OSIRIS-APEX ('APophis EXplorer'). As
15375-509: Was safely stored and ready for its journey to Earth. With the collector head secure inside the SRC, pieces of the sample would no longer be lost. On 7 April 2021, OSIRIS-REx completed its final flyover of Bennu and began drifting away from the asteroid. On 10 May 2021, the spacecraft departed the vicinity of Bennu and began its two-year journey to Earth with the asteroid sample. On 24 September 2023, at 4:42 a.m. MDT ( UTC-06:00 ), at
15500-414: Was scheduled for immediate storage in the Sample-Return Capsule. On 28 October 2020, the sample collector head was secured in the return capsule. Following the separation of the head from the collector arm, the arm was retracted into its launch configuration, and the Sample-Return Capsule lid was closed and latched preparing to return to Earth. In addition to the bulk sampling mechanism, contact pads on
15625-514: Was used to search for a class of near-Earth objects known as Earth-Trojan asteroids as it passed through Sun–Earth L 4 Lagrange point . Between 9–20 February 2017, the OSIRIS-REx team used the spacecraft's MapCam camera to search for the objects, taking about 135 survey images each day for processing by scientists at the University of Arizona. The search was beneficial even though no new trojans were found, as it closely resembled
