Apollo Earthrise Crater: Spacecraft Uses Lunar Feature for Alien Detection
# JUICE Probe’s Radar Instrument Proves Ready for Deep Space Exploration with Lunar Test
The European Space Agency’s (ESA) jupiter Icy Moons Explorer (JUICE) mission has successfully tested it’s Radar for Icy Moons Exploration (RIME) instrument, a crucial step in its ambitious journey to study Jupiter‘s largest moons. The RIME instrument, designed to peer beneath the icy crusts of moons like Ganymede, Europa, and Callisto, underwent a vital calibration using a unique lunar target: Anders’ Earthrise crater.
## A Quite Moment for Sensitive Science
The RIME instrument operates by emitting radio waves and meticulously analyzing the echoes that return. This process requires an exceptionally quiet environment, free from interference, to capture the subtle changes in radio wave signals that reveal subsurface structures. To achieve this, ESA scientists strategically maneuvered the JUICE spacecraft to fly past Anders’ Earthrise crater, a prominent feature on the Moon. During this flyby, all other instruments on the JUICE probe were temporarily silenced, allowing RIME to conduct an uninterrupted eight-minute observation.
