Testing the Juventas CubeSat radar system in ESA's Hertz chamber during November 2021. Part of ESA's Hera mission to the Didymos asteroid system, the 6-unit CubeSat will deploy a quartet of 1.5 m long antennas. This is much much longer than the spacecraft body itself, so the radar testing incorporates a structural model of Juventas to help investigate how it may affect the antenna signals. The test team are using Hertz to measure the entire spherical radiation pattern around the antennas as well as the total radiated power.
