Dale Andersen’s Astrobiology Antarctic Status Report: 18 February 2026: Eclipse Watching And Base Camp Packing
Dale: A partial eclipse over Lake Untersee yesterday—an ordinary piece of celestial clockwork that felt anything but ordinary from the icy shores of Lake Untersee in the mountains of Antarctica. […]
What Cold-water Geysers On Earth Reveal About The Habitability Of Ocean Worlds
In the eastern Utah desert, carbon-dioxide-saturated water bubbles, sprays and foams from the ground. These cold-water geysers, sometimes called ‘soda pop geysers,’ are a new and reliable Earth-based analog for […]
Dale Andersen’s Astrobiology Antarctic Status Report: 15 February 2026: Diving Under The Ice At Lake Untersee
Keith, Sorry for the quiet—our days have been packed, and out here every usable hour feels borrowed. Since my last report the weather has changed its mind a few times. […]
Conceptual Challenges In Astrobiological Analog Environments And Paths Toward Resolution
Analog environments are terrestrial environments that resemble extraterrestrial sites; this concept originated in space sciences for defining methods to study planetary geology, training for missions and testing research instruments.
Orbital Recon: A Decade Of Carbon Dioxide Sublimation At Mars’ South Pole
We’ve monitored the so-called Happy Face Crater in the South Polar region of Mars for over a decade. Two images that we took, one in 2011 and the other in […]
Ice Planet Recon: Looking For Avalanches At Mars’ North Pole
The North Polar Layered Deposits (NPLD) are large layered deposits of dusty water-ice in the northern polar region of Mars. The layering we see is caused mainly by slight variations […]
Crossovers In Ice Planet Exploration – Earth, Europa, And Beyond
Keith’s note: On 11 February 2026 NOVA PBS Host / NewsHour reporter Miles O’Brien conducted a live broadcast from a ship in the southern ocean around Antarctica where Thwaites glacier […]
Active High-Latitude Dune-Gullies On Mars
Gully and defrosting activity have been visible here along the edge of a dune field, along with blocks of frost. Observations of the same area help us check for repeat […]
Sculpting Of Martian Brain Terrain Reveals The Drying Of Ancient Mars
The Martian brain terrain (MBT), characterized by its unique brain-like morphology, is a potential geological archive for finding hints of paleoclimatic conditions during its formation period.
