NASA NEWS BRIEFS RELEASE: 02-70AR June 12, 2002 NASA Astrobiology Institute: The NASA Astrobiology Institute congratulates two new members of the National Academy of Sciences (NAS). Dr. John P. Grotzinger of the NAI Harvard lead team and Dr. Gerald Schubert of the NAI University of California Los Angeles lead team join 13 other NAI researchers as members of the academy. Only 72 new members of the NAS were selected this year. Election to membership is considered one of the highest honors that can be accorded a U.S. scientist or engineer. NASA Scientist Elected: Dr. Lynn Rothschild of NASA Ames Research Center has been elected president of the Society of Protozoologists. The society has an international membership of nearly 1,000. Founded in 1947, the society covers all aspects of protists (unicellular eukaryotic organisms, ranging from the amoeba and paramecium to the causative agents for malaria, giardiasis and sleeping sickness). Protists are critical to modern biology in fields from aging research and photosynthesis to parasitology and AIDS. They played a pivotal role in evolutionary biology as the first organisms with nuclei, and as such gave rise to animals, plants and fungi. Scientist Chosen for Mars Rover Mission: Dr. Nathalie A. Cabrol, a SETI scientist based at NASA Ames, was selected to study sedimentary processes resulting from water activity at the sites to be studied by the 2003 Mars Exploration Rovers. She will join the Athena science team, led by Dr. Steve Squyres of Cornell University. The first rover is due to touch down on Mars in January 2004. Cabrol's primary role will be to identify landforms and deposits from images taken by Mars Global Surveyor cameras and to recommend optimal rover traverses.
