NASA’s DART mission to smack an asteroid launches this week. Here’s how to watch online.

NASA’s asteroid impact mission is set to launch, and you can watch the event and several science briefings live.

The Double Asteroid Redirection Test (DART) is scheduled to launch no earlier than 1:20 a.m. EST (0620 GMT) on Wednesday, Nov. 24 on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

Live launch coverage will run on NASA Television, NASA’s YouTube, the NASA app and agency social media channels starting at 12:30 a.m. EST (0530 GMT). You’ll be able to watch all of the events on this page and’s homepage, courtesy of NASA.

DART has an ambitious mission to impact and redirect the path of an asteroid for the first time in history. It is expected to collide with an asteroid moonlet, Dimorphos, in fall 2022. Dimorphos orbits an asteroid called Didymos, which is close enough for scientists to see any effects using ground-based telescopes. A follow-up mission called Hera (by the European Space Agency) should visit the same system in 2026.

Before and during the mission, NASA has several activities for the public to take part.  Members of the public can register to virtually attend the launch to access resources, watch videos and receive a virtual guest launch passport stamp. 

The agency will have a virtual NASA Social on Facebook, where you can interact with NASA and DART team members and watch the launch. You can also take part in a brief Planetary Defenders campaign, where you can answer questions to earn a “planetary defender” certificate. 

Additionally, you can follow the mission on social media using the hashtag #DARTMission. On Twitter, go to @NASA@AsteroidWatch@NASASocial and @NASA_LSP. On Facebook, go to NASA’s page here and NASA LSP. On Instagram, go to NASA’s page here.

NASA also has a series of live briefings that the public can watch and ask questions about on social media. Below is a listing of the briefings, their participants and public engagement opportunities.
