Help Save the World from Killer Asteroids

The European Space Agency and Johns Hopkins University are collaborating on a trial run to test out the concept behind the Asteroid Impact and Deflection Assessment (AIDA) mission.

The two-part mission will use separate spacecraft to intercept a binary asteroid. The Double Asteroid Redirection Test (DART) craft collides with the smaller of the two asteroids, while the Asteroid Impact Monitor (AIM) surveys the asteroids before and after impact. If the collision changes the relative spin of the asteroid (thus potentially altering its direction and trajectory), the AIM will detect that and relay the information back to Earth.

On Feb. 1, the ESA will release a Call for Experiment Ideas, asking for input on ground or space-based experiments, tests and payload ideas from different domains "including hypervelocity impact and collisional physics, planetary defense, planetary science, human exploration and spacecraft operations related to the goals of the AIDA concept," according to the group's website.
