SpaceX recently tweeted that it has completed a static fire test and is planning to launch the Double Asteroid Redirection Test (DART) on November 23rd. Therefore, on the mentioned day, at 10:21 pm, the company will “intentionally crash the DART spacecraft into an asteroid to see if that is an effective way to change its course, should an Earth-threatening asteroid be discovered in the future.”
The Double Asteroid Redirection Test is looking for a binary asteroid with two bodies dabbed Didymos. The binary asteroid wasn’t on track to meet our planet and would have safely crossed Earth in 2022 and 2024. Didymos A measures 780 meters while the other, Didymos B is 160 meters large.
In terms of objects that could potentially collide with our planet over the next century, NASA has recognized at least 23 objects and is coming up with a protection strategy to keep things safe.
