EQM Thermal Cycle Testing Underway for the Europa Clipper Stellar Reference Unit

NASA’s Europa Clipper will conduct detailed reconnaissance of Jupiter’s moon Europa and investigate whether the icy moon could harbor microbial extraterrestrial life.

NASA JPL selected Sodern in early 2018 to supply the star tracker for this mission. Sodern proudly accepted the challenge and adapted its Hydra star tracker for Jupiter, the harshest radiation environment of the solar system. The mission will study Jupiter’s atmosphere and magnetosphere and characterize the composition and physical properties of Europa, Ganymede, and Callisto.

Earlier this year, Sodern started the qualification testing including vibration, shock, and thermal vacuum testing. Despite the pandemic, Sodern maintained schedule and is nearing the end of the qualification campaign. The Stellar Reference Unit (SRU) recently entered a new qualification phase: Electro Magnetic Compatibility (EMC) qualification campaign.
