How to watch NASA launch its DART anti-asteroid spacecraft tonight

By

NASA is about to launch a spacecraft with a daring mission: To crash into an asteroid, in order to test our planetary defense options. The mission, dubbed DART (Double Asteroid Redirection Test), will head toward a pair of asteroids called Didymos and Dimorphos and will crash into the smaller one in an attempt to knock it off-course. Don’t worry — the asteroid pair doesn’t actually threaten Earth — but this test will demonstrate what defense options Earth might have if an incoming body threatened our planet.

The launch of DART is scheduled for 1:20 a.m. ET on Wednesday, November 24 (10:20 p.m. PT on Tuesday, November 23) and will be livestreamed by NASA. We’ve got all the details on how to watch the launch as it happens.

DART will be launched on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California. It will travel through space until arriving at the double asteroid system in fall 2022 and beginning its collision test.

As SpaceX gears up for the big sixth test flight of its Starship vehicle, NASA has announced its longer term plans for the next generation of SpaceX craft. The company is in the process of developing a human lander for the moon, which NASA intends to use along with a lander from Blue Origin to potentially carry astronauts to the lunar surface as part of the Artemis program.

But NASA won't just be carrying people in its two shiny new spacecraft. The agency announced today that it also intends to use the vehicles to carry cargo such as equipment and infrastructure to the moon.
