South polar CO2 ice could double Mars’ atmosphere
Results from the Shallow Radar (SHARAD) instrument on NASA’s Mars Reconnaissance Orbiter show that the south polar layered deposits on Mars hold about 30 times as much carbon dioxide ice as previously known. If this CO2 were released into the … Continue reading
Mars in the Mojave?
Where do you go to order up some Mars on Earth? Several places, actually, such as the Atacama Desert in Peru (which is very dry), the Dry Valleys of Antarctica (dry and cold), and Houghton Island in Canada’s high arctic … Continue reading
