A Roadmap for NASA's Search for Other Earths

This viewgraph document describes NASA's plan for searching for other planets capable of supporting life. As part of the Vision for Space Exploration, the President requested that NASA pursue the use of advanced telescope searches for Earth-like planets and habitable environments around other stars. Several science questions are asked in the presentation and the answers to some of the questions that NASA has are shown. Plans for future telescopes are reviewed. Three missions, SIM, TPF-C and TPF-I, that are planned to examine possible extra-solar planets, how the information they will give will assist us in further understanding the process of planetary formation, and the possibility that any planet discovered is capable of life is explained.
