The ice-covered world Europa—one of the four large Galilean satellites of Jupiter— may be the best place in the solar system to look for currently existing life beyond Earth. Europa is about the same size as Earth s Moon, but its surface is much more dynamic. Its young, bright, icy landscape is criss- crossed by a network of cracks and ridges, inte...

[1] Certain important molecules of the interstellar medium (ISM), such as H2 and CO2, are believed to have been formed on surfaces of dust grains. We describe experimental methods that we used to study the formation of H2 and CO2 on dust grain analogues in conditions approximating the ones found in key interstellar environments. By using state‐of‐t...

Galileo has now completed 7 years exploring Jupiter. The spacecraft obtained breathtaking views of the four major satellites, and studied Jupiter s clouds and atmospheric composition, rings, small satellites, and magnetic field. It had five successful close flybys and many distant observations of Io. Scientists already knew from Voyager and Earth-b...

[1] We address the problem of compiling bathymetric data sets with heterogeneous coverage and a range of data measurement accuracies. To generate a regularly spaced grid, we are obliged to interpolate sparse data; our objective here is to augment this product with an estimate of confidence in the interpolated bathymetry based on our knowledge of th...

Observations of recent volcanic eruptions in Iceland and detailed studies of sub- glacially erupted deposits and the interaction of lava and pyroclastic flows with snow and ice have provided important new data that should lead to significant advances in the understanding of volcano/ice interaction on Earth and Mars. A conference on this subject, th...
