Europa from Voyager 2, 9 July 1979. Europa, one of Jupiter's moons, seen from the unmanned Voyager 2 spacecraft. The size of our moon, Europa is thought to have a crust of ice 100 kilometres thick which overlies the silicate crust. The complex array of streaks indicate that the crust has been fractured and filled by materials from the interior. The lack of relief, any visible mountains or craters, on its bright limb is consistent with a thick ice crust.
