MEDIA ADVISORY M21-141
NASA to Hold Double Asteroid Redirection Test Launch Preview Briefing
NASA will hold a virtual media briefing at 1 p.m. EDT Thursday, Nov. 4, to preview the launch of the agency’s first planetary defense test mission, the Double Asteroid Redirection Test (DART). As a technology test, the mission will help determine if intentionally crashing a spacecraft into an asteroid is an effective way to change its course, should an Earth-threatening asteroid be discovered in the future. DART’s target asteroid is not a threat to Earth.
The briefing will livestream on NASA Television, the NASA app, the agency's website, and NASA’s Twitter account.
Briefing participants will be:
To participate in the call, media must RSVP by 11 a.m. Thursday, Nov. 4, to Josh Handal at: joshua.a.handal@xxxxxxxx. Please refer to NASA’s media accreditation policy for teleconferences and onsite activities. Media and the public also may refer to the DART press kit for more information on the mission and ask questions during the briefing on social media using #AskNASA.
DART is scheduled to launch no earlier than 1:20 a.m. EST Wednesday, Nov. 24 (10:20 p.m. PST Tuesday, Nov. 23) on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.
The spacecraft is designed to direct itself to impact an asteroid while traveling at a speed of roughly 15,000 miles per hour (24,000 kilometers per hour). Its target is the asteroid moonlet Dimorphos (Greek for “two forms”), which orbits a larger asteroid named Didymos (Greek for “twin”). In fall 2022, DART will impact Dimorphos to change its orbit within the Didymos binary asteroid system. The Didymos system is the ideal candidate for DART because it poses no actual impact threat to Earth, and scientists can measure the change in Dimorphos’ orbit with ground-based telescopes.
To allow the public to share in the excitement of DART, NASA has launched the Planetary Defenders campaign. Participants can answer a short series of questions about planetary defense to earn their planetary defender certificate, which they can download or print, as well as a digital badge to share on social media.

The Johns Hopkins APL has been directed to manage the DART mission for NASA's Planetary Defense Coordination Office as a project of the agency’s Planetary Missions Program Office. The agency provides support for the mission from several centers, including the Jet Propulsion Laboratory in Southern California, Goddard Space Flight Center in Greenbelt, Maryland, Johnson Space Center in Houston, Glenn Research Center in Cleveland, and Langley Research Center in Hampton, Virginia. The launch is managed by NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida.
