NASA's Jet Propulsion Laboratory built and shipped the receiver, transmitter, and electronics necessary to complete the radar instrument for Jupiter Icy Moons Explorer (JUICE), the ESA (European Space Agency) mission to explore Jupiter and its three large icy moons.
In this photo, shot at JPL on April 27, 2020, the transmitter undergoes random vibration testing to ensure the instrument can survive the shaking that comes with launch.
Part of an instrument called Radar for Icy Moon Exploration, or RIME, the transmitter sends out radio waves, which can penetrate surfaces of icy moons and help scientists "see" underneath. A collaboration between JPL and the Italian Space Agency (ASI), RIME is one of 10 instruments that will fly aboard ESA's Jupiter Icy Moons Explorer (JUICE) mission, set to launch in 2022.
