OSIRIS-REx spacecraft provides insight into asteroid Bennu's future orbit

Post by Dragon Fri Aug 13, 2021 8:35 pm

n a study released Wednesday, NASA researchers used precision-tracking data from the agency's Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft to better understand movements of the potentially hazardous asteroid Bennu through the year 2300, significantly reducing uncertainties related to its future orbit, and improving scientists' ability to determine the total impact probability and predict orbits of other asteroids.

On September 25, 2135, an asteroid called Bennu will make a close flyby of Earth.

Our planet’s gravity will tweak Bennu’s path, making it a challenge to calculate its future trajectory.

During the flyby, there is an extremely small chance that Bennu will pass through a “gravitational keyhole” – a region of space that would set it on just the right path to impact Earth, late in the 22nd century.

Although it is difficult to determine the odds of this actually happening, new data from NASA’s OSIRIS-REx spacecraft have allowed scientists to better model how Bennu’s orbit will evolve over time, and to better calculate the probability of an impact.
