Lakes in Noctis Labyrinthus: ancient habitable environments?
Groundwater circulation beneath a massive tectonic rift zone located along the flanks of some the Solar System’s largest volcanic plateaus resulted in the formation more than 3 billion years ago of some the deepest basins on Mars, according to a … Continue reading
Antarctic fungi survive Martian conditions for 18 months on ISS
European scientists have gathered tiny fungi that take shelter in Antarctic rocks and sent them to the International Space Station. After 18 months on board in conditions similar to those on Mars, more than 60% of their cells remained intact, … Continue reading
Antarctic Dry Valleys reveal limits to life?
Failure to find active microbes in coldest Antarctic soils has implications for search for life on Mars. It took Jackie Goordial over 1000 petri dishes before she was ready to accept what she was seeing. Or not seeing. Goordial, a … Continue reading
