Skylab. NASA Skylab space station

This chart describes the Skylab student experiment Bacteria and Spores, proposed by Robert L. Staehle of Rochester, New York. This experiment was intended to determine the effect of the Skylab environment (particularly weightlessness) on the survival, growth rates, and mutations of certain bacteria and spores. In March 1972, NASA and the National Science Teachers Association selected 25 experiment proposals for flight on Skylab. Science advisors from the Marshall Space Flight Center aided and assisted the students in developing the proposals for flight on Skylab.
