2002 Annual Science Report
NASA Johnson Space Center Reporting | JUL 2001 – JUN 2002
Executive Summary
In their searches into the history, occurrence, and nature of life, astrobiologists and other scientists have developed a multitude of techniques for locating some of the telltale tracks that ancient microorganisms left behind. The tracks they search for are the residue of complex interactions that characterize those places in nature where the animate and inanimate met in times past. By learning how to recognize and identify those tracks of life, researchers not only advance their understanding of the processes that produced them, but are also able to use the identifying characteristics of life?s traces in their hunt for life signs in the Solar System and in other star systems.
Introduction
The Johnson Space Center (JSC) node of the NASA Astrobiology Institute is the Institute for the Study of Biomarkers, and is part of the Astromaterials Research and Exploration Science division at JSC. Our institute ...

Project Reports
-
Biogenic Mineral Weathering
- Continued with our experimental project to compare biogenic weathering, sterile controls, and strictly abiogenic weathering
- Developed new morphologic criteria that appear to be distinctive for biogenic weathering textures
- Cataloged existing morphologic features of each type of weathering
- Determined chemical changes on the micrometer and submicrometer level associated with each type of weathering
- Cataloged weathering features in ancient Earth Archean samples and in Martian meteorites ALH84001, Nakhla, and others
