Scientists insisted Dart would not shatter Dimorphos. The Italian Cubesat was released from Dart two weeks ago. Launched last November, the vending machine-size Dart - short for Double Asteroid Redirection Test - navigated to its target using new technology developed by Johns Hopkins University’s Applied Physics Laboratory, the spacecraft builder and mission manager.Ī mini satellite followed a few minutes behind to take photos of the impact. The pair have been orbiting the sun for eons without threatening Earth, making them ideal save-the-world test candidates. Watch our LIVE broadcast at 6pm ET: /czGqnYJIGJ- NASA September 26, 2022 Today, our #DARTMission is set to crash into a non-hazardous asteroid to test deflection technology, should we ever discover a threat. □️ This is only a test – of planetary defense. It’s actually a moonlet of Didymos, Greek for twin, a fast-spinning asteroid five times bigger that flung off the material that formed the junior partner. Monday’s target: a 525-foot (160-meter) asteroid named Dimorphos. The #DARTmission is the world’s first mission to test technology for defending Earth against potential asteroid or comet hazards! /XCBtdsgVV0- Bill Nelson September 26, 2022 Tonight will crash an uncrewed spacecraft into an asteroid. ![]()
