Organic chemistry is ubiquitous in the Solar System, and both Mars and a number of icy satellites of the outer Solar System show substantial promise for having hosted or hosting […]
During 2019 field tests near Greenland’s Summit Station, a high-elevation remote observing station, the WATSON (Wireline Analysis Tool for the Subsurface Observation of Northern ice sheets) instrument is put through […]
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 […]
Cornell University astrobiologists have devised a novel way to determine ocean temperatures of distant worlds based on the thickness of their ice shells, effectively conducting oceanography from space.
Double ridges are sprawling features observed globally across the icy surface of Europa. They consist of two topographic highs flanking a trough.
NASA-supported scientists have published a review of current knowledge regarding how ice-covered moons operate compared to Earth. The paper focuses on the interaction between ice and the liquid ocean of […]
Editor’s note: we currently have a fleet of spacecraft studying Mars – a cold planet with a large variety of geological features governed by frozen water and carbon dioxide. Earth […]
The addition of a high-gain antenna will enable the agency’s Europa Clipper spacecraft in August 2023 – set to launch in October 2024 – to communicate with mission controllers hundreds […]
Editor’s note: as we prepare to visit ice-covered ocean worlds such as Europa and Enceladus – and one day to actually drill beneath their outer surface – we’re certainly going […]
NASA-supported scientists have provided new information about the behavior of organic molecules frozen in brine (e.g. salty water) under conditions similar to the surface of Saturn’s moon Enceladus. The results […]
