Hera’s mini-radar will probe asteroid’s heart

The smallest radar to fly in space has been delivered to ESA for integration aboard the miniature Juventas CubeSat, part of ESA’s Hera mission for planetary defence. The radar will perform the first radar imaging of an asteroid, peering deep beneath the surface of Dimorphos – the Great Pyramid-sized body whose orbit was shifted last year by the impact of NASA’s DART spacecraft.
