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.
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]
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.
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.
NASA's mission to change an asteroid's path, as a test of a way to deflect planetary objects that threaten Earth, succeeded at striking a tiny moonlet 7 million miles away. Correspondent David ...
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.
NASA’s Dart mission ship successfully slammed into the tiny asteroid Dimorphos at 7:14 p.m. Monday, the space agency announced.
65803 Didymos (provisional designation 1996 GT) is a sub-kilometer asteroid and binary system that is classified as a potentially hazardous asteroid and near-Earth object of the Apollo group. [ a ] The asteroid was discovered in 1996 by the Spacewatch survey at Kitt Peak , and its small 160-meter minor-planet moon , named Dimorphos , was ...
