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 DART may refer to: NASA's DART (satellite) , intended to demonstrate an automated navigation and rendezvous capability, launched in April 2005 NASA's Double Asteroid Redirection Test , a planetary defense against near-Earth objects (NEO), launched in November 2021
The game-play mechanic is based loosely on that of the arcade game Missile Command, but with comets falling on cities, rather than missiles.Like Missile Command, players attempt to protect their cities, but rather than using a trackball-controlled targeting cross-hair, players solve math problems that label each comet, which causes a laser to destroy it.
The pioneering NASA spacecraft has made make science fiction a reality - or at least that’s the theory.
NASA’s Dart mission ship successfully slammed into the tiny asteroid Dimorphos at 7:14 p.m. Monday, the space agency announced.
Ever since we learned that an asteroid sucker punched the dinosaurs 66 million years ago, we’ve been a little bit worried it might happen again, but with us in the crosshairs.
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 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.
