Jupiter’s moon Europa is the target of NASA’s planned Europa Mission. The mission hopes to provide the most detailed view yet of the surface and subsurface of Europa and answer some fundamental questions, including whether Europa has a liquid-water ocean beneath a thick ice shelf, and if these conditions may harbor life. It is envisioned the multiple flyby mission would be only the first in a s...

NASA's Galileo mission to Jupiter and improved Earth-based observing capabilities have allowed major advances in our understanding of Jupiter's moons Io, Europa, Ganymede, and Callisto over the past few years. Particularly exciting findings include the evidence for internal liquid water oceans in Callisto and Europa, detection of a strong intrinsic magnetic field within Ganymede, discovery of h...

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...

Three species of the pagurid hermit crab genus Pagurixus Melin, 1939, are reported from Europa Island in the Mozambique Strait, western Indian Ocean: P. haigae Komai & Osawa, 2007, P. annulus n. sp., and P. europa n. sp. Pagurixus haigae is recorded from the western Indian Ocean for the first time. Pagurixus annulus n. sp. and P. europa n. sp. are referred to the P. boninensis (Melin, 1939) spe...

[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...

A new fissiparous asterinid seastar Aquilonastra chantalae sp. nov. is described from Europa Island, one of the Scattered Islands (Les îles Éparses) in the Mozambique Channel. It is compared with the fissiparous asterinid Aquilonastra conandae O'Loughlin & Rowe from the Mascarene Islands. A table of distinguishing diagnostic characters is provided. The asterinid Aquilonastra richmondi O'Loughli...

Introduction: Modeling of the surface stresses on Europa has been performed to date, considering tidal, nonsynchronous, and polar wander sources of stress [3-6]. The results of such models can be used to match lineament orientation with the candidate stress patterns. Moreover, stratigraphic analysis can be used in combination with stress modeling to infer the evolution of Europa’s surface back ...
