RIME « Radar for Icy Moons Exploration »

The JUICE mission’s RIME instrument (Radar for Icy Moons Exploration) is a radar sounder optimized to penetrate ice on the surfaces of Ganymede, Europa and Callisto down to a depth of 9 km and study the subsurface geology and geophysics of the Galilean icy moons with a view to detecting the water thought to exist there.

The French contribution covers simulation and extraction of surface echoes by the IPAG planetology and astrophysics institute in Grenoble.

Simulation of surface echoes:

  • surface/depth ambiguity
  • photo-interpretation
  • execution in routine mode at JPL
