Astrobiology Droid Update: Juice Rerouted To Venus After The First lunar-Earth Flyby

ESA’s Jupiter Icy Moons Explorer (Juice) has successfully completed a world-first lunar-Earth flyby, using the gravity of Earth to send it Venus-bound, on a shortcut to Jupiter through the inner […]

Marine Science Can Contribute to the Search for Extra-Terrestrial Life

Abstract: Life on our planet likely evolved in the ocean, and thus exo-oceans are key habitats to search for extraterrestrial life. We conducted a data-driven bibliographic survey on the astrobiology […]

Energy And Temperature Dependencies For Electron-induced Sputtering From H2O-ice: Implications For The Icy Galilean Moons

To better assess the role that electrons play in exosphere production on icy-rich bodies, we measured the total and O2 sputtering yields from H2O-ice for electrons with energies between 0.75 […]

Properties of Electrons Accelerated by the Ganymede-magnetosphere Interaction: Survey of Juno High-latitude Observations

The encounter between the Jovian co-rotating plasma and Ganymede gives rise to electromagnetic waves that propagate along the magnetic field lines and accelerate particles by resonant or non-resonant wave-particle interaction. […]

Contribution Of PRIDE VLBI Products To The Joint JUICE-Europa Clipper Moons’ Ephemerides Solution

In the coming decade, JUICE and Europa Clipper radio-science will yield the most accurate estimation to date of the Galilean moons’ physical parameters and ephemerides. JUICE’s PRIDE (Planetary Radio Interferometry […]

Astrobiology Recon Missions: Using Ice-penetrating Radar To Find Liquid Water On Other Worlds

The first clue for finding life on other planets is finding liquid water. The moons of Saturn and Jupiter like Enceladus, Ganymede, Europa, and Callisto are suspected of holding oceans […]

Iceworld Morphology: Dome Craters on Ganymede and Callisto May Form by Topographic Relaxation of Pit Craters Aided by Remnant Impact Heat

The icy Galilean satellites display impact crater morphologies that are rare in the Solar System. They deviate from the archetypal sequence of crater morphologies as a function of size found […]
