Over the next 7 months, the ESA Hera mission will study asteroid Dimorphos, measure its mass as well as its shifted orbit and perform its own ‘crash scene investigation’ of the asteroid moon’s impact crater and surrounding surface.

Hera will also deploy two CubeSats, which will fly closer to the asteroid. CubeSat Milani will prospect the mineral make-up of Dimorphos. Juventas will perform the first radar sounding of an asteroid. They might even attempt landing.
