Rotational Dynamics of Europa
The rotational state of Europa is only rather poorly constrained at present. It is known to rotate about an axis that is nearly perpendicular to the orbit plane, at a rate that is nearly constant and approximates the mean orbital rate. Small departures from a constant rotation rate and oscillations of the rotation axis both lead to stresses that may influence the location and orientation of sur...

recently than others; Europa could experience current cryovolcanic and tectonic activity. Global-scale patterns of tectonic Images of Europa from the Galileo spacecraft show a surface features suggest deformation resulting from non-synchronous with a complex history involving tectonic deformation, impact rotation of Europa around Jupiter. Some regions of the lithocratering, and possible emplace...
متن کاملThermal infrared spectroscopy of Europa and Callisto
The trailing hemispheres of Europa and Callisto were observed at 913/•m, and a spectrum of Europa with better spectral resolution and a better signal-to-noise ratio than was previously possible has been derived. The ratio spectrum of the two satellites has a signal-to-noise ratio of approximately 30 for a spectral resolving power of approximately 50. The disk-integrated, effective color tempera...
متن کاملThe state of hydrogen peroxide on Europa
[1] We report infrared reflectance studies in the laboratory that reveal the state of hydrogen peroxide on Europa. Detailed analysis of the 3.5 mm infrared absorption band for hydrogen peroxide grown in a number of water ice environments shows that, for temperatures and concentrations relevant to Europa (80– 130 K), hydrogen peroxide molecules exist in isolated trimers H2O2.2H2O. If the tempera...
