NAI
2003 Annual Science Report
NASA Jet Propulsion Laboratory
Reporting | JUL 2002 – JUN 2003
Executive Summary
The fifth year of the JPL/Caltech/USGS NAI group was a great success with regard to discovery, publication of seminal work, representation of the work to the public, and overall adherence to the roadmap objectives espoused by the NAI. The work was highlighted by several keynote publications in the areas of life detection and biosignature development and testing, and set the stage for future work in the area: work critical to the assessment and testing of instruments for life detection missions. Each Co-I trained several students and postdocs, presented papers at the NAI annual meeting, and many of them presented plenary lectures at national and international meetings. Some of these are highlighted below.
As has been stated previously, the goal of our program slowly evolved from that of the co-evolution of Earth and its life, to that of a goal focused more centrally on ...
