HAMMER Spacecraft

HAMMER stands for Hypervelocity Asteroid Mitigation Mission for Emergency Response. It is a nuclear spacecraft made by a joint venture between NASA, the US National Security Administration and a weapons lab from the US Energy Department. The spacecraft aims to blow any harmful looking asteroids out of the sky before they have a chance to hit out planet. The asteroid that is targeted is Bennu which is circling the sun at 63,000 mph. It is now at a comfortable 54 million miles from Earth.
