The location of a repeat plume detected at Europa is found to be coincident with the strongest ionosphere detection made by Galileo radio occultation in 1997. Melissa A. McGrath, William […]

An Impacting Descent Probe for Europa and the other Galilean Moons of Jupiter
We present a study of an impacting descent probe that increases the science return of spacecraft orbiting or passing an atmosphere-less planetary body of the solar system, such as the […]
Webb Telescope Will Study Our Solar System's Ocean Worlds
NASA’s James Webb Space Telescope will use its infrared capabilities to study the “ocean worlds” of Jupiter’s moon Europa and Saturn’s moon Enceladus, adding to observations previously made by NASA’s […]
A Novel Strategy to Seek Bio-signatures at Enceladus and Europa
A laboratory experiment is suggested in which conditions similar to those in the plume ejecta from Enceladus and, perhaps, Europa are established. Using infrared spectroscopy and polarimetry, the experiment might […]
Pebble Accretion at the Origin of Water in Europa
Despite the fact that the observed gradient in water content among the Galilean satellites is globally consistent with a formation in a circum-Jovian disk on both sides of the snowline, […]
Building A Mass Spectrometer To Land on Europa
An instrument originally developed to search for organic molecules on Mars is being repurposed to potentially hunt for life on a handful of moons in the outer solar system that […]
The Seismic Noise Environment of Europa
Seismic data will be a vital geophysical constraint on internal structure of Europa if we land instruments on the surface. Quantifying expected seismic noise on Europa is an important consideration […]
Taking the Pulse of an Ocean World
Jupiter’s moon Europa is definitely an odd place. Discovered in 1610 by Galileo Galilei, it was first seen in detail only in the late 1970s, after spacecraft visited the Jovian […]
Active Cryovolcanism on Europa?
Evidence for plumes of water on Europa has previously been found using the Hubble Space Telescope (HST) using two different observing techniques. Roth et al. (2014) found line emission from […]
NASA Tests Robotic Tools For Use on Ice Worlds
Want to go ice fishing on Jupiter’s moon Europa? There’s no promising you’ll catch anything, but a new set of robotic prototypes could help. Since 2015, NASA’s Jet Propulsion Laboratory […]
