Dale Andersen’s Astrobiology Antarctic Status Report: 1 February 2026: Drilling Diving Holes
Dale: Hi Keith, We’ve had a productive few days since I last checked in. Yesterday and today we worked on the eastern slopes adjacent to the Anuchin Glacier – Denis […]
What The Earliest Evidence For Life Tells Us About The Early Evolution Of The Biosphere
Life emerged on Earth in an ultramafic world under anaerobic conditions and conditioned by particular environmental characteristics for which no record remains.
Setting A Polyphasic Approach To Study Antarctic Cryptoendolithic Communities As A Toolkit For Astrobiology
The present study has set up a pilot experiment to optimise the most promising assays for investigating the survival of Antarctic microbial cryptoendolithic communities – a natural astrobiological benchmark – […]
Dale Andersen’s Astrobiology Antarctic Status Report: 24 January 2026: Lake Untersee Base Camp Weather Conditions and Forecast
Keith’s note: A quick snapshot of the weather at Lake Untersee and A forecast for the coming week. Dale’s team has a small Ambient WS-4000 weather station set up near […]
Dale Andersen’s Astrobiology Antarctic Status Report: 21 January 2026: Lake Untersee Base Camp Weather
Hi Keith, The past couple of days brought low clouds, some drifting snow, and steady winds that peaked around 30 m/s (~67 mph).
Regolith as a Refuge: Differential Survival of Bacteriophage Qβ in Mars-Analog Environments
Viruses are among the simplest biological entities capable of replication. Their robustness and adaptability make them relevant not only to terrestrial ecosystems but also to astrobiological exploration.
Dale Andersen’s Astrobiology Antarctic Status Report: 18 January 2026: Lake Untersee Base Camp Is Operational
Keith: We just completed the camp last night, and today a storm will move in with 50 mph winds (more?) and perhaps some snow. Should provide a quick test of […]
Organisms In The Atacama Desert Soil Are Remarkably Diverse
A new study shows that resilient and remarkably diverse populations of organisms can persist in the soil despite harsh and extremely dry conditions. An international team led by researchers from […]
Dale Andersen’s Astrobiology Antarctic Status Report: 14 January 2026: Setting Up Base Camp At Lake Untersee
Hi Keith, Since our arrival we have been working hard to get shelter in place. That is always our first priority: establish safe, warm protection from the elements, then we […]
