Astrobiology assesses the habitability of planetary bodies and the potential for extraterrestrial life.
Halite pinnacles from the Yungay area in the hyperarid core of the Atacama Desert harbor cryptoendolithic microbial colonies.
The objective of this observation is to examine a group of gullies that are quite wide, but have short channels, on the eastern side of an impact crater.
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 […]
The search for life on Mars involves the efforts of scientists from many different disciplines. An important aspect of that search is to study Martian sedimentary rocks for information about […]
This roadmap outlines research pathways to determine whether Mars could be warmed with non-biological methods. It does not presuppose that warming Mars is desirable; its purpose is to identify what […]
Earlier this week strong winds over the Saharan Desert blew westwards pushing clouds of dust and sand over southern and central Morocco and out into the Atlantic Ocean. This is […]
