Juventas [ESA]

The Juventas probe is a 6U CubeSat mission to perform low-frequency radar for subsurface sounding as well as a gravimetry measurements of both asteroids' gravity fields in the binary asteroid system (65803) Didymos / Dimorphos.

It will also perform radio science measurements and measure the forces involved in its concluding landing on the smaller of the two asteroids, at the end of its month-long mission.

Juventas is planned to launch with Hera in October 2024 and rendezvous with asteroid Didymos in 2026. It was baselined for an Ariane-62 Astris launch, but in October 2022 a SpaceX Falcon-9 v1.2 (Block 5) was selected.
