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 […]
The Mars Reconnaissance Orbiter was captured into Mars orbit on 10 March 2006. Exactly 20 years later on 10 March 2026, we acquired this image of the South Polar layered […]
The ice along Antarctica’s ‘grounding lines’ has been largely stable over the past 30 years – but ice has retreated by more than 40 km in some areas, a new […]
Hi Keith, The team and I have been home for about two weeks now, settling back into the familiar rhythms of home and work after our time in Antarctica. Our […]
