NasaThe Dual Asteroid Redirection Test, or DART, is the world’s first large-scale planetary defense test, demonstrating a method of asteroid deflection technology. True to its name, DART is a focused mission, proving that a spacecraft can autonomously navigate to and intentionally collide with a target asteroid (called kinetic impact) at around 4 miles per second (6 kilometers per second). . Its target, which poses no threat to Earth, is the moonlet asteroid Dimorphos (Greek for “two shapes”), which orbits a larger asteroid named Didymos (Greek for “twin”).
As part of NASA’s broader planetary defense strategy, DART will simultaneously test new technologies and provide important data to improve our modeling and forecasting capabilities and help us better prepare for an asteroid that could pose a threat. for Earth, if it were to be discovered.
NASA will cover the upcoming pre-launch and launch activities of the agency’s first planetary defense test mission, the Double Asteroid Redirection Test (DART). The mission will help determine if the intentional crash of a spacecraft on an asteroid is an effective way to change its course. DART’s target asteroid is not a threat to Earth.
DART is scheduled to launch no earlier than 1:20 a.m. EST on Wednesday, November 24 (10:20 p.m. PST Tuesday, November 23) an EspaceX Falcon 9 rocket from Vandenberg space base in California.
Coverage of the launch live on NASA Television will begin at 12:30 a.m. EST on Wednesday, November 24, 2021 (9:30 p.m. PST on Tuesday, November 23, 2021), on NASA Television, the NASA app and the agency’s website, with pre-launch and scientific briefings starting Sunday, November 21.
The spacecraft is designed to head toward an impact on an asteroid while traveling at a speed of approximately 15,000 miles per hour (24,000 kilometers per hour). Its target is the moonlet asteroid Dimorphos (Greek for “two shapes”), which orbits a larger asteroid named Didymos (Greek for “twin”). In the fall of 2022, DART will impact Dimorphos to alter its orbit within the Didymos binary asteroid system. The Didymos system is the ideal candidate for DART because it poses no threat of real impact to Earth, and scientists can measure Dimorphos’ orbit change with ground-based telescopes.

wednesday 24 november
12:30 a.m. – NASA TV live launch coverage begins.
Only audio of press conferences and launch coverage will be shown on NASA’s “V” circuits, which can be accessed by dialing 321-867-1220, -1240, -1260 or -7135 . On launch day, “mission audio,” the countdown activities of the launch official without commentary on the NASA TV launch, will be played on 321-867-7135.
Planetary Defender Campaign
To allow the public to share in the enthusiasm of DART, NASA launched the Planetary Defenders campaign. Participants can answer a short series of planetary defense questions to earn their Planetary Defender Certificate, which they can download or print, as well as a digital badge to share on social media using the hashtag #PlanetaryDefender.
The public can register to attend the launch virtually. NASA’s Virtual Guest Program for DART includes curated launch resources, a behind-the-scenes look at the mission, and the ability to get a virtual guest launch passport stamp.
NASA Virtual Social Networks
As we finalize preparations for the launch, we are delighted to invite the public to join our NASA virtual social network for the #DARTMission on Facebook. Stay up to date with the latest mission activities, interact with members of NASA and the DART team in real time, and watch the SpaceX Falcon 9 rocket launch that will propel DART to its destination.
