Survey of earth orbital telescopes and their potential for exobiology

The opportunities that exist for observational exobiology (OE) are examined. The potential uses of free-flying spacecraft, the Space Shuttle, and the Space Station for OE are considered. Proposed experiments are summarized, including research on extrasolar planetary systems, the solar nebula and its analogs, the solar system, giant-planet atmospheres, Titan, comets and asteroids, and molecules in space. A table listing appropriate NASA and ESA telescopes is given.
