Microbial communities in the deep basaltic aquifers of Iceland remain poorly characterized, despite their relevance for understanding subsurface biogeochemical processes, including silicate weathering.
Coordinating with the CaSSIS instrument on the ExoMars Trace Gas Orbiter, we acquired an image at this site for seasonal monitoring.
Thermal measurements constrain the physical properties of icy satellite surfaces, including grain size, porosity, and regolith structure. On Europa, analyses of the Galileo Photopolarimeter-Radiometer (PPR) dataset revealed thermal inertia heterogeneities, […]
Editor’s note: when our first missions – human or robotic – arrive at a new world we’ll want to do glean as much information from space – via fly by […]
Noticeable change on Mars often takes millions of years – but the European Space Agency’s Mars Express has captured a blanket of dark ash creeping across the planet in just […]
Researchers have created the first map of a network of subglacial lakes in the Canadian Arctic showing 33 bodies of water under glaciers.
The material on the floor of this crater appears to have flowed like ice, and contains pits that might result from sublimation of subsurface ice. The surface is entirely dust-covered […]
Debris-covered glaciers (DCGs) at the mid latitudes of Mars preserve ice accumulated in multiple episodes of high obliquity during the Amazonian age. The englacial debris layers formed during interglacials are […]
Between 2.4 and 0.6 Gy ago, our planet underwent several episodes of global glaciations, including the Snowball Earth case that ended 635 My ago.
Editor’s note: When we start to mount Astrobiology missions to explore ocean worlds we’ll need ways for our robotic submersibles to observe and interact with whatever life forms they may […]
