NASA launches new mission to defend Earth

A NASA spacecraft is on a mission to test technology that could defend Earth in the future. The spacecraft will deliberately crash into an asteroid to see if it can change its path. CBS News senior space analyst Bill Harwood joins CBSN's Lana Zak with more.

The asteroid still not as dangerous as the leaders of these countries.

Why isn't Space Force sending Republicans at the asteroid to make it fake?

Almost like a ping-pong effect sounds like really cool technology that could get behind this🤔

If the JW telescope can’t handle a vibration from a breaking tensioner, how the heck is it going to survive the violent vibrations it’ll endure during the launch?

Whats so funny is Leonard made a new movie called Don't Look up...about a asteroid heading towards Earth. 🤔

Send 2 in case the first one directs it our way

A waste of tax payer money, the impactor does not have enough mass to effect anything larger than itself. That being said, that size of matter would not cause any damage here on earth.

Asteroids were passing the earth's orbit since the 80s, and if the likelihood of it hitting the earth is small so why making the weapon is a necessity now ..
