NASA Study: Asteroid’s Orbit, Shape Changed After DART Impact

The asteroid Dimorphos was captured by NASA’s DART mission just two seconds before the spacecraft struck its surface on Sept. 26, 2022. Observations of the asteroid before and after impact suggest it is a loosely packed “rubble pile” object. NASA/Johns Hopkins APL After NASA’s historic Double Asteroid Redirection Test, a JPL-led study has shown that […]
