SETI Institute Reporting  |  JUL 2003 – JUN 2004

The NASA Astrobiology Roadmap asks three fundamental questions: (1) How does life begin and evolve? (2) Does life exist elsewhere in the universe? and (3) What is the future of life on Earth and beyond? The SETI Institute NASA Astrobiology Institute (NAI) team is conducting a set of coupled research projects in the co-evolution of life and its planetary environment. These projects begin by examining certain fundamental ancient transitions that ultimately made complex life possible on Earth. They will conclude with a synthesis that will bring many of the team’s investigations together into an examination of the suitability of planets orbiting M stars for either single-celled or more complex life.


The astrobiology roadmap calls for a strategy "for recognizing novel biosignatures" that "ultimately should accommodate a diversity of habitable conditions, biota and technologies in the universe that probably exceeds the diversity observed on Earth." ... Continue reading.
