Lifesat - A satellite for biological research

The Lifesat program, which provides for the development and operation of an unmanned, free-flying, recoverable, reusable satellite for microgravity biological research, is briefly reviewed. The payload modules will support research in radiation biology, general biology, and biomedical disciplines. The Lifesat will be capable of long-duration flights of up to 60 days and will be able to fly directly into trapped radiation belts and in circular or eccentric polar orbits. The Lifesat will also serve as a testbed for Space Station Freedom experiments.
