NASA tested its first method of deflecting a dangerous asteroid: crashing a space probe into it. DART hit the bullseye and beamed back the footage.

NASA's DART mission was a success. Images taken by satellite show plumes from the asteroid impact, but it could take weeks to monitor for changes in the asteroid’s trajectory.
The 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]
Original – DART's final 5.5 minutes until impact. This replay movie is 10 times faster than reality, except for the last six images, which are shown at the same rate that the spacecraft returned them. Reason Impact video of the DART asteroid redirection test on September 26, 2022. First video of its kind.
The DART impact on the center of Dimorphos decreased the orbital period, previously 11.92 hours, by 33±1 minutes. This large change indicates the recoil from material excavated from the asteroid and ejected into space by the impact (known as ejecta) contributed significant momentum change to the asteroid, beyond that of the DART spacecraft itself.
Recent images released from NASA have revealed new information on the origins of the asteroid system. Nearly two years ago, the Double Asteroid Redirection Test spacecraft, or DART, collided with ...
The Space Shuttle Columbia was lost as it returned from a two-week mission when previously detected damage to the shuttle's thermal protection system (TPS) resulted in the spacecraft breaking apart during reentry at an altitude of just under 65 km and a speed of about Mach 19. Investigation revealed that a piece of foam insulation had fallen ...
