Ganymede's surface temperature varies strongly throughout the day, and around noon near the equator it may become sufficiently warm that the ice surface releases (or sublimates) some small amounts of water molecules.

The mission -- 45 times fly by the moon -- aims to produce high-resolution images of Europa's surface, determine its composition, look for signs of recent or ongoing geological activity, measure the thickness of the moon's icy shell, search for subsurface lakes, and determine the depth and salinity of Europa's ocean, NASA said.
