Artist's rendering of the twin spacecraft of the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission, scheduled to launch in May, 2018. GRACE-FO will track the evolution of Earth's water cycle by monitoring changes in the distribution of mass on Earth. Image credit: NASA/JPL-Caltech

During Cassini’s deepest dive through the Enceladus plume, SwRI scientists discovered hydrogen gas in the material erupting from the Saturnian moon. This discovery provides further evidence for hydrothermal activity (illustrated here) and heightens the possibility that the ocean of Enceladus could have conditions suitable for microbial life.

Scalloped Terrain Led to Finding of Buried Ice on Mars This vertically exaggerated view shows scalloped depressions in a part of Mars where such textures prompted researchers to check for buried ice, using ground-penetrating radar aboard NASA's Mars Reconnaissance Orbiter. They found about as much frozen water as the volume of Lake Superior. Credit: NASA/JPL-Caltech/Univ. of Arizona
