And besides, the lessons the research offers for asteroid trajectory calculation could reduce concerns about potential impacts by other asteroids more than enough to compensate. Technically, that’s a small increase in risk, but the scientists behind the new research say they aren’t worried about a potential impact. While a slightly higher risk than past estimates, it represents a minuscule change in an already minuscule risk, NASA said. Estimates produced before OSIRIS-REx arrived at the space rock tallied the cumulative probability of a Bennu impact between the years 21 at 1 in 2,700, according to NASA. And with that incredibly detailed view of the asteroid, experts studying potential space rock impacts with Earth have been able to fine-tune their existing models of Bennu’s future.Īs a result, scientists behind new research now say they’re confident that the asteroid’s total impact probability through 2300 is just 1 in 1,750. The agency’s OSIRIS-REx spacecraft spent more than two years closely orbiting the space rock. space.The latest tech news, global tech news daily, tech news today, startups, usa tech, asia tech, china tech, eu tech, global tech, in-depth electronics reviews, 24h tech news, 24h tech news, top mobile apps, tech news daily, gaming hardware, big tech news, useful technology tips, expert interviews, reporting on the business of technology, venture capital funding, programing language NASA's OSIRIS-REx spacecraft captured this series of images of asteroid Bennu on April 14, 2020, during the first rehearsal of the mission's sample collection event. (Image credit: NASA/Goddard/University of Arizona)In its first practice run, OSIRIS-REx went through two of the four maneuvers it would perform during a real asteroid-sampling attempt: the orbit departure burn and the "checkpoint" burn.

On Tuesday (April 14), during what NASA calls a "checkpoint rehearsal," OSIRIS-REx got closer to Bennu's surface than ever before while practicing the sample collection process. NASA's OSIRIS-REx spacecraft, which is getting ready to scoop a sample of asteroid Bennu, has successfully completed a partial dress rehearsal for its historic trip to the asteroid's surface.
