OSIRIS-REx in Launch Configuration

OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) is a NASA asteroid-study and sample-render mission.[12] The mission'southward primary goal is to obtain a sample of at least 60 g (2.one oz) from 101955 Bennu, a carbonaceous near-Earth asteroid, and return the sample to Earth for a detailed assay. The material returned is expected to enable scientists to learn more virtually the formation and development of the Solar Organisation, its initial stages of planet formation, and the source of organic compounds that led to the formation of life on Globe.[13]

OSIRIS-Male monarch was launched on eight September 2016, flew past Earth on 22 September 2017, and rendezvoused with Bennu on 3 Dec 2018.[14] It spent the next several months analyzing the surface to find a suitable site from which to extract a sample. On 20 October 2020, OSIRIS-Male monarch touched down on Bennu and successfully collected a sample.[xv] [16] Though some of the sample escaped when the flap that should have closed the sampler head was jammed open up by larger rocks, NASA is confident that they were able to retain between 400 g and over 1 kg of sample material, well in excess of the 60 g (ii.i oz) minimum target mass.[17] [18] OSIRIS-REx is expected to return with its sample to Earth on 24 September 2023.[19]

Bennu was chosen as the target of written report because it is a "time capsule" from the birth of the Solar System.[twenty] Bennu has a very dark surface and is classified every bit a B-type asteroid, a sub-blazon of the carbonaceous C-type asteroids. Such asteroids are considered "archaic", having undergone trivial geological change from their fourth dimension of formation. In item, Bennu was selected because of the availability of pristine carbonaceous material, a cardinal element in organic molecules necessary for life too as representative of thing from earlier 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.[ane]

The cost of the mission is approximately The states$800 meg,[21] non including the Atlas V launch vehicle, which is well-nigh US$183.5 million.[22] It is the third planetary science mission selected in the New Frontiers program, after Juno and New Horizons. The master investigator is Dante Lauretta from the University of Arizona. If successful, OSIRIS-REx will be the first United States spacecraft to return samples from an asteroid. The Japanese probe Hayabusa returned samples from 25143 Itokawa in 2010, and Hayabusa2 returned from 162173 Ryugu in Dec 2020. On 10 May 2021, OSIRIS-Rex successfully completed its departure from Bennu and began its two-year return to Earth.[23] [24]

Mission [edit]

OSIRIS-Rex mission overview video

Overall management, applied science and navigation for the mission is provided past NASA'due south Goddard Space Flying Center, while the University of Arizona's Lunar and Planetary Laboratory provides principal scientific discipline operations and Lockheed Martin Infinite Systems built the spacecraft and provides mission operations.[2] The scientific discipline team includes members from the United States, Canada, France, Frg, Great britain, and Italy.[25]

After traveling for approximately two years, the spacecraft rendezvoused with asteroid 101955 Bennu in Dec 2018,[26] and began 505 days of surface mapping at a distance of approximately 5 km (3.1 mi).[1] Results of that mapping were used past the mission team to select the site from which to take a sample of the asteroid's surface.[27] Then a shut approach (without landing) was carried out to allow extension of a robotic arm to gather the sample.[28]

Post-obit a drove of material (60 grams), the sample volition be returned to Earth in a 46 kg (101 lb) capsule similar to that which returned the samples of a comet 81P/Wild on the Stardust spacecraft. The return trip to Earth will exist shorter and the capsule will country with a parachute at the Utah Exam and Grooming Range in September 2023 earlier beingness transported to the Johnson Space Center for processing in a dedicated inquiry facility.[ane]

Launch [edit]

The launch was on 8 September 2016 at 23:05 UTC on a United Launch Alliance Atlas Five 411 from Cape Canaveral, Space Launch Circuitous 41.[3] The 411 rocket configuration consists of a RD-180 powered first phase with a single AJ-60A solid fuel booster, and a Centaur upper stage.[29] OSIRIS-Rex separated from the launch vehicle 55 minutes subsequently ignition.[two] The launch was alleged "exactly perfect" by the mission'due south principal investigator, with no anomalies worked before or during launch.[30]

Cruise [edit]

OSIRIS-REx entered the cruise phase shortly after separation from the launch vehicle, following successful solar console deployment, propulsion system initiation, and institution of a advice link with Globe.[30] Its hyperbolic escape speed from Earth was about five.41 km/southward (3.36 mi/s).[31] On 28 December 2016, the spacecraft successfully performed its first deep space maneuver to modify its velocity past 431 yard/s (1,550 km/h) using 354 kg (780 lb) of fuel.[32] [33] An additional, smaller firing of its thrusters on eighteen January 2017 further refined its course for an Earth gravity assist on 22 September 2017.[32] The cruise stage lasted until its run into with Bennu in Dec 2018,[26] after which information technology entered its science and sample collection phase.[32]

During its cruise phase, OSIRIS-REx was used to search for a form of near-Globe objects known equally Globe-Trojan asteroids as it passed through Sunday–Globe Fiftyiv Lagrange bespeak. Between 9–twenty February 2017, the OSIRIS-King team used the spacecraft's MapCam photographic camera to search for the objects, taking about 135 survey images each mean solar day for processing by scientists at the University of Arizona. The search was beneficial even though no new trojans were establish,[34] every bit it closely resembled the operation required as the spacecraft approached Bennu, searching for natural satellites and other potential hazards.[33] [35] On 12 February 2017, while 673×10 ^ half dozen km (418×10 ^ 6 mi) from Jupiter, the PolyCam instrument aboard OSIRIS-Rex successfully imaged the giant planet and three of its moons, Callisto, Io, and Ganymede.[36]

OSIRIS-Male monarch flew by Earth on 22 September 2017.[37]

Arrival and survey [edit]

On 3 December 2018, NASA affirmed that OSIRIS-REx had matched the speed and orbit of Bennu at a distance of nigh nineteen km (12 mi), finer reaching the asteroid. OSIRIS-REx performed closer passes of the Bennu surface, initially at most 6.5 km (4.0 mi) through December to further refine the shape and orbit of Bennu. Preliminary spectroscopic surveys of the asteroid'southward surface by OSIRIS-REx spacecraft, detected the presence of hydrated minerals in the form of clay. While researchers doubtable that Bennu was also small to host water, the hydroxyl groups may have come up from water presence in its parent body before Bennu split off.[38] [39]

OSIRIS-Male monarch entered orbit around Bennu on 31 December 2018 at about i.75 km (1.09 mi) to beginning its extensive remote mapping and sensing campaign for the pick of a sample site. This is the closest distance that whatsoever spacecraft has orbited a angelic object, surpassing the Rosetta 's orbit of comet 67P/Churyumov–Gerasimenko at 7 km (4.3 mi).[14] [40] At this distance, information technology takes the spacecraft 62 hours to orbit Bennu.[41] At the end of this detailed survey, the spacecraft entered a closer orbit with a radius of ane km (0.62 mi).[42]

Sample acquisition [edit]

Artist's concept of TAGSAM musical instrument in operation

Procedure [edit]

Rehearsals were performed before the sampling event, during which the solar arrays were to exist raised into a Y-shaped configuration to minimize the chance of dust accumulation during contact and provide more than ground clearance in instance the spacecraft tips over (upward to 45°) during contact.[25] The descent was very tiresome to minimize thruster firings prior to contact in order to reduce the likelihood of asteroid surface contamination by unreacted hydrazine propellant. Contact with the surface of Bennu was to exist detected using accelerometers, and the impact forcefulness was meant to be dissipated by a spring in the TAGSAM arm.[43]

Upon surface contact by the TAGSAM instrument, a outburst of nitrogen gas was released, which was meant to blow regolith particles smaller than 2 cm (0.eight in) into the sampler head at the terminate of the robotic arm. A five-second timer express the collection time to mitigate the adventure of a collision. After the timer expired, the back-away maneuver executed a prophylactic departure from the asteroid.[25]

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 instance it was necessary to return for some other sampling endeavor. It would then accept images of the TAGSAM head to verify a sample had been acquired. If a sample was caused, the spacecraft would rotate almost the brusque axis of the sample arm to decide sample mass by measuring momentum of inertia and decide if information technology was in backlog of the required sixty thousand (2.1 oz).

Both the braking and rotation maneuvers were canceled every bit images of the sample container clearly showed a big backlog of fabric was collected, a portion of which was able to escape through the container's seal due to some material jamming the mechanism open up. The collected material was scheduled for immediate storage in the Sample-Return Capsule.[44] [25] On 28 October 2020, the sample collector head was secured in the render capsule. Post-obit the severance of the caput from the collector arm, the arm will and so be retracted into its launch configuration, and the Sample-Render Capsule hat will exist closed and latched preparing to render to World.[45] [46]

In add-on to the bulk sampling mechanism, contact pads on the terminate of the sampling head fabricated of tiny stainless steel loops (Velcro)[47] passively collected dust grains smaller than 1 mm.

Operations [edit]

OSIRIS-REx successfully stows its sample of asteroid Bennu in October 2020.

NASA selected the final 4 candidate sample sites in August 2019, named Nightingale, Kingfisher, Osprey, and Sandpiper.[48] On 12 December 2019, they announced that Nightingale had been selected as the primary sample site and Osprey was selected as the backup site.[49] Both located inside craters, Nightingale is near Bennu's northward pole while Osprey is well-nigh the equator.[fifty]

NASA's initial plans were to perform the kickoff sampling in late August 2020;[51] NASA'southward originally planned Touch-and-Go (TAG) sample collection outcome was scheduled for 25 Baronial 2020, but was rescheduled for 20 October 2020, at 22:xiii UTC.[52] [53] On 15 Apr 2020, the first sample collection rehearsal was successfully performed at the Nightingale sample site. The practice took OSIRIS-King as close as 65 m (213 ft) from the surface before performing a back-away fire.[54] [55] A second rehearsal was successfully completed on 11 Baronial 2020, bringing OSIRIS-REx down to 40 g (130 ft) from the surface. This was the concluding rehearsal earlier the sample collection scheduled to take place on twenty October 2020, at 22:thirteen UTC.[56] [57]

At 22:thirteen UTC , on 20 October 2020, OSIRIS-REx successfully touched-down on Bennu.[58] NASA confirmed via images taken during sampling that the sampler had made contact. The spacecraft touched down within 92 cm (36 in) of the target location.[59] [60] A sample of the asteroid which was estimated to counterbalance at least 2 ounces (sixty grams) was collected by OSIRIS-King post-obit the touch downward.[xv] After imaging the TAGSAM head, NASA ended that there are rocks wedged in the mylar flap that is meant to go along the sample in, causing the sample to slowly escape into space.[61] In order to preclude further loss of the sample through the flaps, NASA canceled the previously-planned spinning maneuver to decide the mass of the sample likewise as a navigational braking maneuver and decided to stow the sample on 27 Oct 2020 rather than 2 Nov 2020 as was originally planned, which was completed successfully. Information technology was seen that the collector head hovering over the SRC afterward the TAGSAM arm moved it into the proper position for capture and later the collector head secured onto the capture ring in the Sample Return Capsule.[61]

When the head was seated into the Sample-Render Sheathing's capture ring on 28 October 2020, the spacecraft performed a "backout cheque", which commanded the TAGSAM arm to dorsum out of the capsule. This maneuver is designed to tug on the collector caput and ensure that the latches – which keep the collector head in place – are well secured. Post-obit the test, the mission team received telemetry confirming that the caput is properly secured in the Sample-Return Capsule. Thereafter, on 28 October 2020, two mechanical parts on the TAGSAM arm must first be disconnected – these are the tube that carried the nitrogen gas to the TAGSAM caput during sample collection and the TAGSAM arm itself. Over the next several hours, the mission team commanded the spacecraft to cut the tube that stirred up the sample through the TAGSAM caput during sample collection, and separate the collector caput from the TAGSAM arm. Once the squad confirmed these activities were done, information technology 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.[62] To seal the SRC, the spacecraft closes the lid and and then secures two internal latches. Additionally, on inspecting images, information technology was observed that a few particles had escaped from the collector head during the stowage process, but it was confirmed that no particles would hinder the stowage process, since the team was confident that a plentiful amount of material remains inside of the head, existence more than than the needed amount, 60 k (2.1 oz), that is, between 60 g (2.1 oz) and two,000 k (71 oz). The sample of Bennu is safely stored and fix for its journey to Earth. At present that the collector caput is secure inside the SRC, pieces of the sample will no longer be lost.[63]

Sample return [edit]

The OSIRIS-REx squad is now preparing the spacecraft for the next phase of the mission, the return prowl to World.[64] [65] On 7 Apr 2021, OSIRIS-REx completed its final flyover of Bennu and began slowly drifting away from the asteroid.[66] On 10 May 2021, OSIRIS-REx officially left the Bennu asteroid and began its two year journeying to Earth with the asteroid sample.[67]

On 24 September 2023, the OSIRIS-REx return sheathing is scheduled to re-enter World's atmosphere and country nether a parachute at the Air Force's Utah Exam and Preparation Range.[68] The sample would exist curated at NASA's Astromaterials Enquiry and Exploration Science Advisers (ARES) and at Nihon'due south Extraterrestrial Sample Curation Center.[68] [69] The sample material from the asteroid would be distributed to requesting organisations worldwide past ARES.[24]

Extended mission [edit]

An extended mission is under consideration to rendezvous with near-Earth asteroid Apophis in April 2029, but after its close arroyo with Globe. The mission contour would be like to that carried out at Bennu, with a slow approach phase and rendezvous earlier entering orbit almost the asteroid.[70]

Proper noun [edit]

OSIRIS-Rex is an acronym, and each letter of the alphabet or combination of messages relates to office of the projection:[71]

  • O – origins
  • SI – spectral interpretation
  • RI – resource identification
  • Due south – security
  • King – regolith explorer

Each of these words was chosen to represent an aspect of this mission.[71] For case, the S, for security means the security of Earth from hazardous NEO.[71] Specifically it refers to amend understanding the Yarkovsky upshot, that changes the trajectory of the asteroid.[71] Regolith Explorer means that the mission will study the texture, morphology, geochemistry, and spectral properties of the regolith of asteroid Bennu.[71]

When its heritage concept was proposed in the Discovery Programme in 2004, it was called merely OSIRIS, with REx for "Regolith Explorer" used descriptively rather than equally role of the proper name.[72] This mission is too sometimes called New Frontiers three, for it existence the third of the New Frontiers programme missions.[72] [73]

The acronym OSIRIS was chosen in reference to the aboriginal mythological Egyptian god Osiris, the underworld lord of the dead. He was classically depicted as a green-skinned homo with a pharaoh's beard, partially mummy-wrapped at the legs and wearing a distinctive crown with two big ostrich feathers at either side.His name was chosen for this mission [ commendation needed ] equally asteroid Bennu is a threatening Globe impactor, with an estimated 1-in-1800 chance of hit Globe in the twelvemonth 2170. Rex ways "king" in Latin.[74] [75]

Science objectives [edit]

Sample Render Capsule Exploded View

The scientific discipline objectives of the mission are:[76]

  • Return and analyze a sample of pristine carbonaceous asteroid regolith in an amount sufficient to written report the nature, history, and distribution of its elective minerals and organic compounds
  • Map the global properties, chemical science, and mineralogy of a primitive carbonaceous asteroid to characterize its geologic and dynamic history and provide context for the returned samples
  • Document the texture, morphology, geochemistry, and spectral properties of the regolith at the sampling site in situ at scales down to millimeters
  • Measure the Yarkovsky effect (a thermal strength on the object) on a potentially hazardous asteroid and constrain the asteroid backdrop that contribute to this effect
  • Narrate the integrated global properties of a primitive carbonaceous asteroid to permit for direct comparing with ground-based telescopic information of the entire asteroid population

Scope observations have helped define the orbit of 101955 Bennu, a near-Earth object (NEO) with a hateful diameter in the range of 480 to 511 g (1,575 to i,677 ft).[77] 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 is reasonably well known, scientists keep to refine it. It is critical to know the orbit of Bennu considering recent calculations produced a cumulative probability of 1 in 1410 (or 0.071%) of impact with Earth in the menses 2169 to 2199.[78] One of the mission objectives is to refine understanding of non-gravitational effects (such equally the Yarkovsky effect) on this orbit, and the implications of those effects for Bennu's collision probability. Knowing Bennu's physical backdrop will be critical for future scientists to understand when developing an asteroid impact abstention mission.[79]

Specifications [edit]

  • The sample-render sheathing volition reenter the Earth's atmosphere for a parachute assisted landing. The sheathing with encased samples will be retrieved from Earth's surface and studied, as was washed with the Stardust mission.

Instruments [edit]

In addition to its telecommunication equipment, the spacecraft carries a suite of instruments to prototype and analyze the asteroid on many wavelengths,[81] and retrieve a physical sample to render to Earth. The Planetary Society coordinated a campaign to invite interested persons to take their names or artwork on the mission'due south spirit of exploration saved on a microchip at present carried in the spacecraft.[82]

OCAMS [edit]

The OSIRIS-REx Photographic camera Suite (OCAMS) consists of the PolyCam, the MapCam, and the SamCam.[81] Together, they larn data on asteroid Bennu by providing global mapping, sample site reconnaissance and label, high-resolution imaging, and records of the sample conquering.[83]

  • PolyCam, an 20 cm (7.9 in) telescope, acquired visible-light images with increasingly higher resolution on approach the asteroid and high-resolution surface images from orbit
  • MapCam searches for satellites and outgassing plumes. It maps the asteroid in 4 blue, greenish, ruby-red and near infrared channels, and informs the model of Bennu'due south shape and provides high resolution imaging of the potential sample sites
  • SamCam continuously documents the sample acquisitions

OVIRS [edit]

The OSIRIS-King Visible and IR Spectrometer (OVIRS) is a spectrometer which maps minerals and organic substances on the asteroid's surface.[81] It provides full-disc asteroid spectral data at 20 m resolution. It maps blueish to well-nigh-infrared, 400–4300 nm, with a spectral resolution of 7.5–22 nm.[84] This information will be used in concert with OTES spectra to guide sample-site option. The spectral ranges and resolving powers are sufficient to provide surface maps of carbonates, silicates, sulfates, oxides, adsorbed water and a wide range of organic compounds.[ citation needed ]

OTES [edit]

The OSIRIS-King Thermal Emission Spectrometer (OTES) provides thermal emission spectral maps and local spectral information of candidate sample sites in the thermal infrared channel covering 4–l µm, again to map mineral and organic substances.[81] The wavelength range, spectral resolution, and radiometric performance are sufficient to resolve and identify silicates, carbonates, sulfates, phosphates, oxides, and hydroxide minerals. OTES is also used to measure the total thermal emission from Bennu in back up of the requirement to measure emitted radiation globally.[ citation needed ]

Based on the functioning of Mini-TES in the dusty surface environs of Mars, OTES was designed to exist resilient to extreme grit contamination on the optical elements.[ citation needed ]

REXIS [edit]

The Regolith Ten-ray Imaging Spectrometer (REXIS) will provide an X-ray spectroscopy map of Bennu to map element abundances.[81] REXIS is a collaborative development by 4 groups within Massachusetts Institute of Technology (MIT) and Harvard University, with the potential to involve more than 100 students throughout the process. REXIS is based on flight heritage hardware, thereby minimizing elements of technical risk, schedule take chances, and cost risk.[ citation needed ]

REXIS is a coded discontinuity soft X-ray (0.iii–7.five keV) telescope that images 10-ray fluorescence line emission produced by the absorption of solar Ten-rays and the solar current of air with elements in the regolith of Bennu leading to local X-ray emissions. Images are formed with 21 arcminute resolution (4.iii k spatial resolution at a distance of 700 thousand). Imaging is achieved by correlating the detected X-ray paradigm with a 64×64 element random mask (1.536 mm pixels). REXIS will store each X-ray outcome data in order to maximize the data storage usage and to minimize the hazard. The pixels volition exist addressed in 64×64 bins and the 0.3–7.5 keV range volition be covered past v broad bands and eleven narrow line bands. A 24 second resolution time tag will exist interleaved with the event information to business relationship for Bennu rotation. Images will be reconstructed on the ground after downlink of the outcome listing. Images are formed simultaneously in sixteen 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 stage 5B, a 21 day orbit 700 m from the surface of Bennu, a full of at least 133 events/asteroid pixel/energy band are expected under 2 keV; enough to obtain significant constraints on element abundances at scales larger than 10 m.[ citation needed ]

On 11 November 2019, university students and researchers involved in the mission accidentally discovered X-ray burst from a black hole name MAXI J0637-430 locate 30,000 low-cal-years abroad, during observing the asteroid with REXIS.[85]

OLA [edit]

The OSIRIS-REx Light amplification by stimulated emission of radiation Altimeter (OLA) is a scanning and lidar instrument that will provide high resolution topographical data throughout the mission.[81] The information received by OLA creates global topographic maps of Bennu, local maps of candidate sample sites, ranging in support of other instruments, and support navigation and gravity analyses.[ commendation needed ]

OLA scans the surface of Bennu at specific intervals to rapidly map the unabridged surface of the asteroid to achieve its primary objective of producing local and global topographic maps. The data nerveless by OLA will also be used to develop a control network relative to the center of mass of the asteroid and to heighten and refine gravitational studies of Bennu.[ citation needed ]

OLA has a unmarried common receiver and ii complementary transmitter assemblies that enhance the resolution of the information brought dorsum. OLA'south high-free energy laser transmitter is used for ranging and mapping from ane to 7.v km (0.62 to iv.66 mi). The depression-energy transmitter is used for ranging and imaging from 0.5 to i km (0.31 to 0.62 mi). The repetition rate of these transmitters sets the information acquisition rate of OLA. Laser pulses from both the depression and high energy transmitters are directed onto a movable scanning mirror, which is co-aligned with the field of view of the receiver telescope limiting the effects of background solar radiations. Each pulse provides target range, azimuth, top, received intensity and a time-tag.[ commendation needed ]

OLA was funded by the Canadian Infinite Agency (CSA) and was built by MDA at Brampton, Ontario, Canada.[86] OLA was delivered for integration with the spacecraft on 17 November 2015.[87] The lead instrument scientist of OLA is Michael Daly from York University.[88]

TAGSAM [edit]

TAGSAM arm test before launch

The sample-return system, called Touch-And-Go Sample Acquisition Mechanism (TAGSAM), consists of a sampler caput with an articulated 3.35 m (11.0 ft) arm.[2] [81] An on-board nitrogen source will support upwardly to three separate sampling attempts for a minimum total amount of threescore yard (ii.1 oz) of sample. The surface contact pads volition too collect fine-grained material.[ citation needed ]

Highlights of the TAGSAM musical instrument and technique include:

  • Relative approach velocity of 10 cm/s (3.9 in/s)[89]
  • Contact within 25 m (82 ft) of selected location
  • OCAMS documents sampling at 1 Hz
  • Collect samples in less than 5 seconds, direct nitrogen (N2) annular jet fluidizes regolith, surface-contact pad captures surface sample
  • Verify bulk sample collection via spacecraft inertia change; surface sample past imaging sampler head
  • Sampler head stored in sample-return capsule and returned to Earth

Cooperation with JAXA [edit]

Hayabusa2 is a similar mission from JAXA to collect samples from near-Earth asteroid 162173 Ryugu. Information technology arrived at the asteroid in June 2018, left in November 2019 after ii successful sample collections, and returned to Earth in December 2020. The recovery capsule of Hayabusa2 re-entered Earth temper and landed in Commonwealth of australia, every bit planned, on 5 December 2020. The sample contents will be extensively analyzed, including h2o content which will provide clues on the initial formation of the asteroid. The main module of Hayabusa2 is performing a swing-by procedure to "push" information technology onward to its adjacent destination, asteroid 1998KY26. Due to the similarity and overlapping timelines of the two missions (OSIRIS-Rex is withal in the return stage), NASA and JAXA signed an agreement to collaborate on sample exchange and research.[90] [91] The ii teams visited each other, with representatives from JAXA visiting the OSIRIS-REx Science Operations Heart at the University of Arizona, and members of the OSIRIS-REx team traveling to Nippon to meet with the Hayabusa2 team.[92] [93] The teams are sharing software, data, and techniques for analysis, and will eventually exchange portions of the samples that are returned to Earth.[94] [95]

OSIRIS-Rex 2 [edit]

OSIRIS-King 2 was a 2012 mission concept to replicate the original spacecraft for a double mission, with the 2d vehicle collecting samples from the 2 moons of Mars, Phobos and Deimos. It was stated that this mission would be both the quickest and to the lowest degree expensive way to become samples from the moons.[96] [97]
