OSIRIS-REx Mission Design: Sample Acquisition Campaign

The Origins Spectral Interpretation Resource Identification Security - Regolith Explorer (OSIRIS-REx) spacecraft arrived at near-Earth asteroid Bennu in December 2018. After studying the asteroid for nearly two years, the spacecraft successfully performed a Touch-And-Go (TAG) sample collection maneuver on October 20, 2020. The spacecraft will remain in asteroid Bennu’s vicinity until May 10, when the mission will enter its Return Cruise phase and begin its two-year journey back to Earth. This data visualization presents the mission’s complete trajectory during its time at Bennu. This visualization depicts the OSIRIS-REx spacecraft’s trajectory around the asteroid Bennu from the initial arrival in Dec 2018 through the final departure in April 2021. The trajectory is presented in a Sun Bennu North reference frame. Several mission segments are highlighted in white, leading up to the TAG sample collection maneuver on Oct 20, 2020.

OSIRIS-REx is a mission to study and map near-Earth asteroid Bennu. Its primary science objective is to collect a sample of Bennu in mid 2020 and return it to Earth in late 2023. In preparation, mission planners have identified four candidate sample sites on Bennu s rocky surface where OSIRIS-REx could briefly touch down to collect its sample. The mission will down-select to the final two sites – a primary and a backup – in December 2019. Like the mythological Bennu bird for which the asteroid is named, all of the candidate sample sites refer to birds that can be found in Egypt.Learn more about the candidate sample sites on Bennu.

Recorded audio from the OSIRIS-REx approach media teleconference on August 24, 2018, with accompanying presenter graphics. Individual graphics are available below.Watch this video on the NASA.gov Video YouTube channel. NASA is hosting a media teleconference at 2 p.m. EDT Friday, Aug. 24, to provide an update on upcoming activities related to the agency’s first mission to return a sample of an asteroid to Earth.The Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft, which launched on Sept. 8, 2016, started asteroid science operations last week, began imaging asteroid Bennu for the first time, and is now preparing to conduct the necessary approach maneuvers to rendezvous with Bennu on Dec. 3. The mission represents a valuable opportunity to learn more about the origins of our solar system, the sources of water and organic molecules on Earth, and the hazards and resources in near-Earth space. The briefing participants are:Lori Glaze, acting director of the Planetary Science Division at NASA HeadquartersDante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, TucsonMichael Moreau, OSIRIS-REx flight dynamics system manager at NASA’s Goddard Space Flight CenterSandy Freund, OSIRIS-REx mission support area manager at Lockheed Martin SpaceFor more information, go to nasa.gov/osiris-rex or asteroidmission.org. 1.

The Origins Spectral Interpretation Resource Identification Security - Regolith Explorer spacecraft will travel to a near-Earth asteroid, called Bennu (formerly 1999 RQ36), and bring at least a 2.1-ounce sample back to Earth for study. The mission will help scientists investigate how planets formed and how life began, as well as improve our understanding of asteroids that could impact Earth.OSIRIS-REx launched on Sept. 8, 2016, at 7:05 p.m. EDT. As planned, the spacecraft will reach its target asteroid in 2018 and return a sample to Earth in 2023. These animations depict the journey of OSIRIS-REx to Bennu and back, including the complex maneuvers that the spacecraft will perform in the asteroid s entire surface. OSIRIS-REx scans the surface of Bennu. Video available in both 30fps and 60fps formats. OSIRIS-REx scans one of several potential sample locations.

On September 24, 2023, OSIRIS-REx will return its sample of asteroid Bennu to Earth. The sample return capsule will detach from the spacecraft, perform an entry, descent and landing sequence, and touch down at the UTTR facility in Utah. The Bennu samples will be taken to Johnson Space Center in Houston, Texas for curation, and will be studied by scientists around the world for decades to come. OSIRIS-REx returns to Earth with its sample of asteroid Bennu. After releasing the sample return capsule on September 24, 2023, the spacecraft will go into orbit around the Sun.Watch this video on the NASA.gov Video YouTube channel.

OSIRIS-REx is a solar-powered spacecraft built by Lockheed Martin Space Systems. The spacecraft bus measures 3.2 meters high by 2.4 meters wide (about 10x8 feet). With its solar arrays deployed, the spacecraft spans 6.2 meters in length (over 20 feet). A high-gain antenna on the sun-pointed side of OSIRIS-REx enables communication with Earth. On the opposite side is the TAGSAM, a 3.4-meter-long, folding arm that will reach out and grab a sample of the mission and the student-built REXIS X-ray spectrometer for detecting individual atomic elements.Mission planners will use this suite of instruments to determine the best location on Bennu for collecting the sample, which OSIRIS-REx will return to Earth in 2023.

After leaving Earth in September 2016, OSIRIS-REx spent two years traveling to asteroid Bennu. In September 2017 it flew by Earth for a gravity assist, putting the spacecraft in the right orbital inclination to rendezvous with Bennu in December 2018. OSIRIS-REx makes its outbound cruise to asteroid Bennu.

OSIRIS-REx is on a mission to study asteroid Bennu and return a sample to Earth.
