The Spacecraft Galileo

Scientists preparing for NASA's proposed Jupiter icy Moons Orbiter believe that Jupiter's moons Europa may be a corrosive mixture of acid and peroxide. Thus, it may not be the ideal place for life to exist as was thought possibly to be the case. Virtually , all the information we have about Europa comes from the spacecraft Galileo, which completed its mission to study. Although the general perception of Europa is of a frozen crust of water ice harboring a salty subterranean ocean kilometer below, researchers studying the most recent measurements say light reflected from the moons icy surface bears the spectral fingerprints of hydrogen peroxide and strong acids, however , they accept that it could just be a thin surface dusting and might not come from the ocean below.
