NASA’s first major asteroid sample recovery rehearsal for its OSIRIS-REx mission, at Lockheed Martin in Littleton, Colorado, on June 27, 2023. AFPPIX: NASA's first mission to retrieve an asteroid sample and return it to US soil is expected to reach a perilous finale on Sunday with a descent into the Utah desert.
Touchdown is scheduled for Sunday at around 9:00 am local time , at a military testing site in the western state. If all goes well, two successive parachutes will bring the capsule to a soft landing on the desert floor, where it will be retrieved by prepositioned staff. “Sample return missions are hard. There’s a number of things that can go wrong,“ said Sandra Freund, Lockheed Martin’s OSIRIS-REx program manager.
The next day, the sample will be flown to a highly specialized laboratory at NASA's Johnson Space Center in Houston, Texas.Some of the sample will be for studies now, with the rest stored away for future generations equipped with better technology -- a practice first started during the Apollo missions to the Moon.
That mass would be the “largest from beyond the orbit of the moon” NASA program executive Melissa Morris said.The first samples brought to Earth by asteroids were carried out by Japanese probes in 2010 and 2020, with the latter found to contain uracil, one of the building blocks of RNA.
