As Europa moves slightly away from +Jupiter, Jupiter's gravitational force decreases, causing Europa to relax back into a more +spherical shape, and creating tides in its ocean. The orbital eccentricity of Europa is +continuously pumped by its mean-motion resonance with Io. +Thus, the tidal flexing kneads Europa's interior and gives it a source of heat, possibly +allowing its ocean to stay liquid while driving subsurface geological processes. +The ultimate source of this energy is Jupiter's rotation, which is tapped by Io +through the tides it raises on Jupiter and is transferred to Europa and Ganymede by the +orbital resonance. + + spase://CNES/Person/CDPP-AMDA/NAIF + PrincipalInvestigator + + + jup-moons-orb + PartOf + Jupiter Moons + + + + spase://SMWG/Repository/CDPP/AMDA + Online + Open + + CDPP/AMDA HAPI Server + https://amda.irap.omp.eu/service/hapi + + europa-orb-all + Web Service to this product using the HAPI interface. + + CSV + Thank you for acknowledging the use of AMDA in publications with wording like "Data analysis was performed with the AMDA science analysis system provided by the Centre de Données de la Physique des Plasmas (CDPP) supported by CNRS, CNES, Observatoire de Paris and Université Paul Sabatier, Toulouse".
