DART
DART
Overview:

The Double Asteroid Redirection Test (DART) will be the first demonstration of the kinetic impact technique to change the motion of an asteroid in space. This is a science-driven test of one of the technologies for preventing the Earth impact of a hazardous asteroid, with the primary objective to demonstrate and measure the effects of a kinetic impact on a small asteroid. The target is the binary near-Earth asteroid (65803) Didymos. 

DART is a simple, single-string (limited or no redundancy) spacecraft design and carries a single instrument, the Didymos Reconnaissance and Asteroid Camera for OpNav (DRACO), for targeting and observation (determine impact site and geologic context) during the impact rendezvous. DRACO is a high-resolution imager derived from the one flown on New Horizons LORRI (link is external). The spacecraft will weigh about 500kg, and impact Didymos B (the smaller secondary, moonlet) with a relative velocity of about 6 km/s (13,000 mph).
