NASA snaps monster meteor fireball STREAK over Bering Sea

The US space agency is preparing its Double Asteroid Redirection Test (DART).

This is an ambitious plan slam a spacecraft into an asteroid at 13,500mph to redirect it away from Earth, the mission’s Project Scientist told Express.co.uk.

Dr Nancy Chabot, the DART Coordination Lead, said: “The DART mission is demonstrating technology that could be used in a planetary defence kinetic impactor mission, which is designed to be most effective for asteroids in the size range of roughly 100-500 meters in diameter.

“If an asteroid of this size hit the Earth, it would cause large scale regional devastation.”
