NASAs DART spacecraft will intentionally crash into an asteroid to test if impacting an object is a viable way to deflect an asteroid, should a threat ever be discovered in the future. Watch as NASA astronaut Shane Kimbrough and European Space Agency astronaut Thomas Pesquet demonstrate how DARTs mission will work. Spoiler alert: its like a pillow fight in microgravity.
DART is a spacecraft designed to impact an asteroid as a test of technology. DARTs target asteroid is NOT a threat to Earth. This asteroid system is a perfect testing ground to see if intentionally crashing a spacecraft into an asteroid is an effective way to change its course, should an Earth-threatening asteroid be discovered in the future.
