DART – the Double Asteroid Redirect Test – is zeroing in on its target. The first mission to impact and move an asteroid is just days away from its goal. The impact will happen at 7:15 p.m. EDT (23:15 UTC) on September 26, 2022. Earlier this month, NASA reported that DART had its first look at its target, the asteroid system Didymos and its moon Dimorphos (or Didymos b), back in July. The LICIACube, which will witness the impact, successfully separated from DART on September 11. DART is the first real test of our ability to defend Earth from an asteroid on a collision course with our world. For this test, DART is targeting Dimorphos, a little moonlet that’s just 500 feet (150 m) in diameter. NASA hopes the nudge from DART will push it slightly from its regular orbit. This test will show if we’re ready to take on any threatening asteroids that could be headed our way. https://earthsky.org/space/dart-impac...
