Juventas CubeSat coming in for asteroid landing

Hera's Juventas CubeSat coming in for landing on the smaller Didymos asteroid. ESA’s Hera mission for planetary defence, being designed to survey the smallest asteroid ever explored, is really three spacecraft in one. The main mothership will carry two briefcase-sized CubeSats, which will touch down on the target body. Hera’s Juventas CubeSat will perform the first radar probe of an asteroid, while the APEX CubeSat will perform a multispectral mineral survey of its makeup. These two nanosatellites will fly closer to their target asteroid and take more risks than the main Hera spacecraft, and will both end up landing on the surface once their main mission goals are achieved.
