title: Survey of Earth orbital telescopes and their potential for exobiology.
abstract: A series of Workshops on Exobiology in Earth Orbit held at NASA Ames Research Center has recently concluded.  The draft of the final report from these Workshops contains a prioritized list of telescopic observations (possible only from above the Earth's atmosphere) that relate to the origin and evolution of the biogenic elements and compounds from their nucleosynthetic creation within stars to their inclusion in living systems.  These orbital observations and the ground based laboratory and theoretical research necessary to support them have been termed Observational Exobiology.  The details available on spacecraft, platforms and instrumentation most likely to be launched in the near future by the U.S. and Europe were considered in the Workshops.  The purpose was to determine what observational programs would be tractible and what area of interest to exobiology required hardware and/or mission capabilities not yet envisioned.  This paper summarizes the exciting opportunities that exist for Observational Exobiology.
