Hera's Juventas CubeSat – being developed for ESA by the GomSpace company in Luxembourg and Denmark with GMV in Romania, Emtronix in Luxembourg and Astronika in Poland – will be much smaller than these planetary missions, measuring just 30 x 20 x 10 cm. Juventas’s low frequency radar will unfurl a quartet of 1.5 m-long antennas, larger than the CubeSat itself, placed perpendicular to each other to provide a circular polarisation radar signal, placing fewer constraints on spacecraft operations and providing easier-to-interpret data on both Didymos asteroids.
