NASA Invites Media to Witness World's First Planetary Defense Test
NASA's Double Asteroid Redirection Test (DART), the world's first mission to test technology for defending Earth against potential asteroid or comet hazards, will impact its target asteroid-which poses no threat to Earth-at 7:14 p.m. EDT on Monday, Sept. 26.
Among other activities, NASA will host a televised briefing beginning at 6 p.m. on Sept. 26 from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland. APL is the builder and manager of the DART spacecraft for NASA. [Ed Comment: For timings please see below-JR]
This test will show a spacecraft can autonomously navigate to a target asteroid and intentionally collide with it to change the asteroid's motion in a way that can be measured using ground-based telescopes. DART will provide important data to help better prepare for an asteroid that might pose an impact hazard to Earth, should one ever be discovered.
