Conrad gave a lecture entitled, "A Bipolar Year: What We Can Learn About Looking for Life on Other Planets by Working in Cold Deserts." In part 2 of this edited transcript, Conrad describes how her work in cold deserts could aid the search for alien life. 01/12/09



 
 The Nuts and Bolts
The Mars Reconnaissance Orbiter launched on August 12, and when it arrives at Mars it will search for evidence of water in the martian atmosphere, surface, and subsurface. This orbiter also will provide detailed surveys of the planet, identifying any obstacles that could jeopardize the safety of future landers and rovers. 01/12/09

 The Lure of Europa
The discovery that Europa most likely has a cold, salty ocean beneath its frozen icy crust has put Europa on the short list of objects in our solar system that astrobiologists would like to study further 01/12/09

 Deciphering Mars: Follow the Water
At the recent Earth System Processes II conference, Farmer gave a talk on the current state of understanding about Mars: what we know and what we'd like to know. In this, the first of a three-part series, he explains why "following the water" is central to NASA's program of Mars exploration. 01/12/09



 
 Deciphering Mars: The Current Decade
At the recent Earth System Processes II conference, Farmer gave a talk on the current state of understanding about Mars: what we know and what we'd like to know. In this, the second of a three-part series, he discusses what scientists have learned from recent NASA and ESA missions to the red planet. 01/12/09



 
 Comet Cookbook
Now, astronomers using data from NASA's Spitzer Space Telescope and Deep Impact have analyzed that soup and begun to come up with a recipe for what makes planets, comets and other bodies in our solar system. 01/12/09
