'The impact probability went up just a little bit but it's not a significant change, the impact probability is pretty much the same,' lead author Davide Farnocchia, who works at NASA's Center for Near Earth Object Studies in California, said during a news conference held Wednesday (Aug. 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. 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. Technically, that's a small increase in risk, but the scientists behind the new research say they aren't worried about a potential impact. scientists study the rugged surface of near-Earth asteroid Bennu.

While a slightly higher risk than past estimates, it represents a minuscule change in an already minuscule risk, NASA said. that are at first unfocused and use them to slowly fine-tune the Webb telescope. From the report: 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. As a scientist with college degree in Astronomy, minor in Physics and. 'As 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,' reports. NASA's OSIRIS-REx spacecraft has been orbiting an asteroid called Bennu for more than two years to fine-tune the agency's existing models of its trajectory.
