NASA to crash spacecraft on asteroid to divert its movement: Where to watch

NASA’s Double Asteroid Redirection Test, the world’s first mission to test technology for defending Earth against potential asteroid or comet hazards, will hit a target asteroid on 26 September. 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, NASA said about the mission in its website. Here's how to watch: Monday, Sept. 12 9 a.m. – NASA will host a hybrid media day at APL focused on the technology enabling the DART spacecraft to autonomously navigate to and impact its target asteroid. Thursday, Sept. 22 3 p.m. – Media briefing at NASA Headquarters to preview DART’s final activities before its impact with Dimorphos.
