Still Waters Posted September 23, 2022 #1 Share Posted September 23, 2022 (IP: Staff) · NASA's Double Asteroid Redirection Test (DART) spacecraft is set to slam into an asteroid on Monday (Sept. 26), in the first ever test of humanity's ability to deflect life-threatening space rocks before they collide with Earth. The 1,210-pound (550 kilograms) DART craft, a squat cube-shaped probe consisting of sensors, an antenna, an ion thruster and two 28-foot-long (8.5 meters) solar arrays, will smash into the asteroid Dimorphos while traveling at roughly 13,420 mph (21,160 km/h). The goal of the probe's test is to slow the orbit of the 525-feet-wide (160 m) Dimorphos around its larger partner — the 1,280-feet-wide (390 m) asteroid Didymos. Neither asteroid poses a threat to Earth, as they will be more than 7 million miles (11 million kilometers) from our planet at the time of DART's impact, but NASA scientists want to use the test to study how a more dangerous asteroid might one day be nudged from its deadly collision course. DART will collide with Dimorphos at 7:14 p.m. ET on Monday, with live coverage set to begin at 6 p.m. ET on NASA TV. https://www.livescience.com/dart-test-what-you-need-to-know https://www.nasa.gov/nasalive Related: 7 Top Link to comment Share on other sites More sharing options...
