Planetary Group Seminar: AIDA: Asteroid Impact & Deflection Assessment (J.-B. Vincent)

The AIDA mission will be the first space experiment to demonstrate asteroid impact hazard mitigation by using a kinetic impactor to deflect an asteroid. It consists of ESA's orbiter AIM which will orbit the binary asteroid Didymos in 2022, and NASA's DART projectile scheduled for impact on the secondary in October 2022, while Didymos is at its closest approach to Earth. Both AIM and ground based telescopes will measure the change of orbit of the secondary. AIDA will return vital data to determine the momentum transfer efficiency of the kinetic impact and measure key physical properties of the target asteroid. Additionally, a lander and a full suite of instruments will give us the first tomographic map of an asteroid interior.
