Ice Volcanoes Reshape Europa's Chaotic Surface . Ice-spewing volcanoes and the grinding and tearing of tectonic plates have reshaped the chaotic surface of Jupiter's frozen moon Europa, images from NASA's Galileo spacecraft reveal. ... Although the images do not show currently active ice volcanoes or geysers, they do reveal flows of material on the surface that probably originated from them, said Galileo imaging team member Dr. Ronald Greeley of Arizona State University, Tempe. ... Europa . ...

... It can · · obtain ice sample from 20 cm or deeper surface layer, then melt it and extract biomass from the ice surface water by filtration; Laser TOF MS for the measurements of element composition of the biomass; Gas TOF MS for the detection of: 1) volatile components, generated at the heating of biomass sample (closed window mode); 2) secondary ions , emitted from ice matrix by the influence of energetic magnetosphere ... Spectrum of yeast sample. ... Laser TOF MS 6. ...

... They had expected to see impact craters like those on the other terrestrial bodies and from their number per unit area to estimate the age of Io's surface. ... This may have been the most important single discovery of the Voyager missions; it was the first real proof that the interiors of other "terrestrial" bodies are actually hot and active. ... A nalysis of the Voyager images led scienties to believe that the lava flows on Io's surface were composed mostly of various compounds of molten sulfur. ...
