Space experiments

The National Aeronautics and Space Administration is currently considering proposals for experiments to be carried on manned and unmanned space flights during the next five‐year period. Room for experiments is available on Gemini and Apollo manned flights, weather satellites, sounding rockets, the X‐15 research plane, orbiting observatories, and balloons. A full description of the flights and deadlines for proposals can be obtained from NASA's Office of Space Science and Applications.
