NASA spacecraft hits asteroid

NASA estimates the size of Asteroid Dimorphos to be the equivalent of a football stadium, although this asteroid does not threaten Earth.

However, scientists will be able to put technology that could save an asteroid impact from becoming disastrous to the test thanks to this mission.

The refrigerator-sized plane, which was launched in November atop a SpaceX Falcon 9 rocket, covered over 7 million miles .

The Greek word "dimorphos" translates to "two forms," and its diameter is 525 feet (or 160 metres).

The Didymos Reconnaissance and Asteroid Camera will be used to capture photos for use in DART's optical navigation system.

DART was moving at 14,000 mph when it collided with the ground, a speed that would have allowed it to cross the previous four miles in a single second.
