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.
