What is AIDA?

The Asteroid Impact & Deflection Assessment (AIDA) mission is a joint project of ESA and NASA. It is a technology demonstration of the kinetic impactor concept to deflect a small asteroid and to characterize its physical properties. It started in 2011 as a joint study between JHU/APL, NASA, the Côte d’Azur Observatory (OCA, Nice, France) and DLR. The mission went into phase A/B1 at ESA in early 2015 for 15 months and will enter into Phase A at NASA in spring 2015 (see News below). You can watch the Video explaining the concept on the ESA website (click here).

AIDA is composed of the projectile called DART (Double Asteroid Redirection Test) and an observer satellite called AIM (Asteroid Impact Mission), each under study by NASA and ESA, respectively.The combination of both spacecrafts is referred to as AIDA. As in the separate DART and AIM studies, the target of this mission is the binary asteroid system (65803) Didymos. For a successful joint mission, one spacecraft, DART would impact the secondary of the Didymos binary system in October 2022 while AIM would first characterize the target asteroid (surface and internal properties), observe the impact event and measure any change in the relative orbit.
