NASA to Provide Update on Agency's First Asteroid Sample Collection Attempt
NASA will hold a teleconference to provide an update on the agency's first attempt to make contact with the surface of asteroid Bennu and collect a sample next month.
NASA will hold a media teleconference to provide an update on the agency's first attempt to make contact with the surface of asteroid Bennu and collect a sample next month.
The Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer spacecraft will travel to the asteroid's surface during its first sample collection attempt Oct. 20. Its sampling mechanism will touch Bennu's surface for several seconds, fire a charge of pressurized nitrogen to disturb the surface, and collect a sample before the spacecraft backs away.
Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona Lunar and Planetary Laboratory, will be joined by four other team members on Thursday, Sept. 24, 12 p.m. (MT), in a livestreamed teleconference. Lauretta will provide background on the mission, the science of Bennu and what will happen with the sample once it is collected.
In response to rocky conditions discovered on the asteroid's surface when OSIRIS-REx began orbiting Bennu in 2018, the mission team has reduced the sample area to one-tenth of the area in the original plan. This means the spacecraft must target Bennu's surface with even greater accuracy.
A building-size boulder situated on Nightingale crater's eastern rim could pose a hazard to the spacecraft as it backs away from the asteroid after collecting the sample. The OSIRIS-REx team performed two rehearsal operations to prepare for these challenges and is ready.
The spacecraft is scheduled to begin the journey back to Earth next year, arriving with the sample in 2023.
Studying Bennu helps researchers learn more about the origins of our solar system, sources of water and organic molecules on Earth, and hazards and resources in near-Earth space. For more information on OSIRIS-Rex, visit https://www.nasa.gov/osiris-rex and https://www.asteroidmission.org.
