Exobiology and Planetary Protection of icy moons
Space Science Reviews, 2010The outer solar system is an important area of investigation for exobiology, the study of life in the universe. Several moons of the outer planets involve processes and structures comparable to those thought to have played an important role in the emergence of life on Earth, such as the formation and exchange of organic materials between different ...

Performances of the Passive SAR Imaging of Jupiter’s Icy Moons
IEEE Transactions on Geoscience and Remote Sensing, 2022With the development of the JUpiter ICy moons Explorer (JUICE)/Radar for Icy Moons Exploration (RIME) [European Space Agency (ESA)] and Europa Clipper/Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON) [National Aeronautics and Space Administration (NASA)] instruments, designed to study the subsurface of the Galilean moons ...

For Principal Investigator Michele Dougherty of the Magnetometer (MAG) team, the Cassini mission highlight occurred in February 2005. This was when she and her colleagues determined that Saturn’s magnetic field lines were unexpectedly bending as they went by the satellite Enceladus. This was possibly a sign that the tiny moon, even with its low gravity,

Spectroscopy of Icy Moon Surface Materials
Space Science Reviews, 2010Remote sensing of icy objects in the outer solar system relies upon availability of appropriate laboratory measurements. Surface deposits of specific substances often provide our most direct route to understanding interior composition, thereby informing theories of endogenic surface modification, exogenic surface processing and processes involving ...

The Dust Halo of Saturn's Largest Icy Moon, Rhea
Science, 2008Saturn's moon Rhea had been considered massive enough to retain a thin, externally generated atmosphere capable of locally affecting Saturn's magnetosphere. The Cassini spacecraft's in situ observations reveal that energetic electrons are depleted in the moon's vicinity.

Trajectories for Flyby Sample Return at Icy Moons [PDF]
Journal of Spacecraft and Rockets, 2018 Ballistic trajectories are computed that aim to achieve a sample-return mission to Europa, Enceladus, or Titan without capturing, descending, or landing.

Habitability potential of icy moons: a comparative study
2014Looking for habitable conditions in the outer solar system our research focuses on the natural satellites rather than the planets themselves. Indeed, the habitable zone as traditionally defined may be larger than originally con-ceived. The strong gravitational pull caused by the giant planets may produce enough energy to sufficiently heat the interiors

Radar Glory from Buried Craters on Icy Moons [PDF]
Science, 1986 Three ice-covered moons of Jupiter, in comparison with rocky planets and Earth's moon, produce radar echoes of astounding strengths and bizarre polarizations. Scattering from buried craters can explain these and other anomalous properties of the echoes. The role of such craters is analogous to that of the water droplets that create the apparition known

Europa Clipper mission: the habitability of an icy moon
2015 IEEE Aerospace Conference, 2015Europa, the fourth largest moon of Jupiter, is believed to be one of the best places in the solar system to look for extant life beyond Earth. The 2011 Planetary Decadal Survey, Vision and Voyages, states: “Because of this ocean's potential suitability for life, Europa is one of the most important targets in all of planetary science”.
