چکیده
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 emplacement of ice-rich materials and sphere have been fractured, with icy plates separated and roperhaps liquids on the surface. Differences in impact crater distributions suggest that some areas have been resurfaced more tated into new positions. The dimensions of these plates suggest

Contents — P through Z Methods for Detecting Current Geological Activity on Europa
Introduction: Jupiter's satellite Europa could be the site of recent, or current, geological activity. Future missions to the Jovian system, such as the proposed Jupiter Icy Moons Orbiter, should search for evidence of such activity as a way to determine the potential for liquid water, and perhaps the astrobi-ological potential, of Europa. Searches for geological activity can include change det...
متن کاملCombining Galileo Ssi and Nims Spectra for Europa
Introduction: Prior to spacecraft exploration, ground-based observations of Jupiter's moon Europa revealed that the surface had the spectral signature of water ice [1,2]. Later observations, by the Voyager and Galileo spacecraft, have shown that the surface can be divided up into two main geological and colorimet-ric/spectral units [3]. Most of the surface has a bright, whitish color that is at...
متن کاملSearching for liquid water in Europa by using surface observatories.
Liquid water, as far as we know, is an indispensable ingredient of life. Therefore, locating reservoirs of liquid water in extraterrestrial bodies is a necessary prerequisite to searching for life. Recent geological and geophysical observations from the Galileo spacecraft, though not unambiguous, hint at the possibility of a subsurface ocean in the Jovian moon Europa. After summarizing present ...
متن کاملGalileo plasma observations at Europa: Ion energy spectra and moments
Observations from the Galileo plasma analyzer (PLS) recorded during two near encounters with Europa are reported. The measured ion energy spectra show that the ions near Europa are a mix of thermalized torus plasmas with approximately Maxwellian ion velocity distributions and partially thermalized pickup ions with ring distributions. The measurements are used to determine plasma moments includi...
متن کاملSalts and Radiation Products on the Surface of Europa
The surface of Europa could contain the compositional imprint of a underlying interior ocean, but competing hypotheses differ over whether spectral observations from the Galileo spacecraft show the signature of ocean evaporates or simply surface radiation products unrelated to the interior. Using adaptive optics at the W.M. Keck Observatory, we have obtained spatially resolved spectra of most o...
