LAUREL, Md. (NASA PR) — NASA’s Double Asteroid Redirection Test (DART), the world’s first mission to test technology for defending Earth against potential asteroid or comet hazards, will impact its target asteroid—which poses no threat to Earth—at 7:14 p.m. EDT on Monday, Sept. 26.

Among other activities, NASA will host a televised briefing beginning at 6 p.m. on Sept. 26 from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland. APL is the builder and manager of the DART spacecraft for NASA.

This test will show a spacecraft can autonomously navigate to a target asteroid and intentionally collide with it to change the asteroid’s motion in a way that can be measured using ground-based telescopes. DART will provide important data to help better prepare for an asteroid that might pose an impact hazard to Earth, should one ever be discovered.

The following is a list of activities for DART’s impact with the asteroid Dimorphos (all times Eastern):

Monday, Sept. 26 (DART Impact Day)

  • 6 p.m. – Live coverage of DART’s impact with the asteroid Dimorphos will air on NASA TV and the agency’s website. The public also can watch live on agency social media accounts on FacebookTwitter, and YouTube.
  • ​7:14 p.m. –DART’s kinetic impact with asteroid Dimorphos.
  • ​​8 p.m. – Media briefing at Johns Hopkins APL to hear from mission experts immediately following DART’s successful impact with asteroid Dimorphos.

    I dare Cyclone Ian to blow that away

    I sincerely admire the title.

    You know, based on the legal theory that defined Celestial Bodies in the 1960’s, the object they impact will no longer be a Celestial Body since it will cease to be “in Situ” and will now be on an “artificial” orbit as the result of human action. Technically NASA will be the owner of an asteroid if this is successful.

    what a waste
