Double Asteroid Redirection Test (DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs).[4][5] It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on.[6] The selected target asteroid, Dimorphos, is a minor-planet moon of the asteroid Didymos; neither asteroid poses an impact threat to Earth, but their joint characteristics made them an ideal benchmarking target. Launched on 24 November 2021, the DART spacecraft successfully collided with Dimorphos on 26 September 2022 at 23:14 UTC about 11 million kilometers (6.8 million miles) from Earth. The collision shortened Dimorphos' orbit by 32 minutes, greatly in excess of the pre-defined success threshold of 73 seconds.[7][8][9] DART's success in deflecting Dimorphos was due to the momentum transfer associated with the recoil of the ejected debris, which was substantially larger than that caused by the impact itself.
Asteroid 99942 Apophis is a near-Earth object (NEO) that is estimated to be about 1,100 feet (335 meters) across. It was discovered in 2004 and was identified as one of the most hazardous asteroids that could impact Earth.
In December 2004, initial observations indicated a 2.7% probability that Apophis would hit Earth on April 13, 2029. This caused a brief period of concern and a great deal of media attention. However, NASA has stated that Earth is safe from Apophis for 100-plus years.
Scientists have to consider a range of possible trajectories for Apophis as it approaches Earth in the coming years. Some of these trajectories line up with regions of space called gravitational keyholes. If Apophis were to pass through a keyhole, Earth's gravity would bend its path in just the right way to cause an impact on a subsequent orbit.
NASA has a mission called OSIRIS-APEX to shadow Apophis just after it barely avoids hitting Earth.
