People on Earth will get a close look at NASA's plan to destroy an asteroid.
The final destination of NASA's Double Asteroid Redirect Test is the surface of an asteroid called Dimorphos, which it will crash into at speeds of over 15,000 miles per hour. The researchers hope that the collision will change the asteroid's trajectory.
Dimorphos and Didymos don't pose any danger to Earth, but the experiment is designed to see if a similar impact could make a difference if an asteroid were to be found.
During its last approach, DART will be on its own. The DART is 163 meters wide and will be guided by an autopilot on board. 163 meters is large on a human scale, but small and so far away that researchers don't know what it looks like, and won't have a good image of the asteroid until after the collision.
People will be able to watch the action behind the scenes thanks to DART.
Elena Adams, DART mission systems engineer, said that an image is coming in every second and that is still amazing.
NASA's coverage of the DART impact will start at 6PM on Monday, September 26th.
This post will be updated with NASA's live stream. You can watch live coverage on NASA's website or on the agency's social media accounts.
NASA's media channel will have a feed of pictures from the craft starting around 6:30PM.
