Nathalie Cabrol ( - ) http://web99.arc.nasa.gov/~ncabrol/ Notable Achievements Leads Mars Rover field experiments. Expeditions include the Andes to some of the highest lakes in the world. Occupation/Field of Study: Planetary Geologist specializing in Mars Exploration Zone: Air and Space: Mars, Solar System, outer space, extra-terrestrial life; Land: exobiology, planetary geology, volcanic lakes, volcanoes; Location of Activity: South America: Andes, Ecuador; Period of Activity: 1951-2000; 2001- current; Biography Nathalie Cabrol is a planetary geologist who works with NASA Ames Research Center analyzing images and data from the Mars mission launches for evidence of water to find out if Mars developed environments that could have been, or still could be, habitable by living organisms. She has led rover field experiments and helped to determine the landing sites for the latest Mars Expeditions. Searching for a better understanding of Martian environments, Cabrol has been leading the Licancabur Expeditions to the highest lake on Earth (5916 m or 19523 ft) on the boundary of Chile and Bolivia where the conditions are analogous to those of ancient Martian lakes: low oxygen, intense UV (ultraviolet) radiation, and an atmospheric pressure only 50 percent of what it is at sea level. Cabrol is also a principal investigator with the Search for Extraterrestrial Intelligence (SETI) Institute hoping to find evidence of life beyond earth.
