How To Livestream Nasa's Asteroid-Smashing Test

Scientists at NASA are getting ready for the first mission in the world to test planetary defence, and they want you to watch.

The space agency's Double Asteroid Redirection Test (DART) will test technology to protect Earth from future asteroids and comets by crashing into an asteroid at about 15,000 mph.

This asteroid doesn't pose a threat to Earth, but it will be used to test technology. The target is a small moonlet of a larger asteroid called Dimorphos. It is about 525 feet wide.

On September 26, NASA plans to live stream the whole event, and people can watch on its website, Facebook, Twitter, or YouTube.

A live briefing will happen at 6 p.m. ET on "Impact Day" from the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, which builds and runs the DART spacecraft.

Scientists sent the small, $330 million probe nearly seven million miles away from Earth when they launched it last fall.

It is carrying a small spacecraft called LICIACube, which will be sent out from DART 10 days before the collision to try to take pictures of the collision and the debris that comes from it.

At this time, astronomers have an estimate that there are approximately 25,000 near-Earth asteroids that are at least 150 metres (500 feet) in size.

DART will hopefully give researchers important information that will help them get ready for an asteroid that could destroy our planet in the future, if they find one.
