#DARTmission: Engineer Builds Spacecraft to Impact Asteroid

  • english

Before NASA’s #DARTmission could launch on its journey to slam into an asteroid — in the name of science — it had to be designed, built, launched, and flown.

Johns Hopkins APL systems engineer Elena Adams worked to make sure that the mission will hit its mark: Dimorphos, the moonlet orbiting asteroid Didymos.

The DART mission is a test of a technique that could be used to mitigate the threat of an asteroid on a collision course with Earth, should one be discovered in the future.

DART’s target is not a threat to Earth.

While no known asteroid larger than 140 meters in size has a significant chance to hit Earth for the next 100 years, only about 40% of those asteroids have been found.
