This chart describes the Skylab student experiment Motor Sensory Performance, proposed by Kathy L. Jackson of Houston, Texas. Her proposal was a very simple but effective test to measure the potential degradation of man's motor-sensory skills while weightless. Without knowing whether or not man can retain a high level of competency in the performance of various tasks after long exposure to weightlessness, this capability could not be fully known. Skylab, with its long-duration missions, provided an ideal testing situation. The experiment Kathy Jackson proposed was similar in application to the tasks involved in docking one spacecraft to another using manual control. It required one of the greatest tests of the motor-sensory capabilities of man. 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.

KENNEDY SPACE CENTER, Fla. -- STS-108 Mission Specialist Daniel M. Tani arrives at KSC in a T-38 jet trainer. He and the rest of the crew will be preparing for launch Nov. 29 on Space Shuttle Endeavour. Liftoff is scheduled for <A HREF="javascript:convertit(7:41:00pm','ED')" TITLE="Convert to alternate measure">7:41 p.m.</a> EST. Top priorities for the STS-108 (UF-1) mission of Endeavour are rotation of the International Space Station Expedition Three and Expedition Four crews, bringing water, equipment and supplies to the station in the Multi-Purpose Logistics Module Raffaello, and completion of spacewalk and robotics tasks. Mission Specialists Linda A. Godwin and Tani will take part in the spacewalk to install thermal blankets over two pieces of equipment at the bases of the Space Station's solar wings. Other crew members are Commander Dominic L. Gorie and Pilot Mark E. Kelly
