Astronaut Mark Lee floats free of tether during EVA

STS064-45-014 (16 Sept. 1994) --- Backdropped against a massive wall of white clouds 130 nautical miles below, astronaut Mark C. Lee floats freely as he tests the new Simplified Aid for EVA Rescue (SAFER) system. The image was exposed with a 35mm camera from the shirt-sleeve environment of the space shuttle Discovery. Astronauts Lee and Carl J. Meade took turns using the SAFER hardware during their shared Extravehicular Activity (EVA) on Sept. 16, 1994. The test of SAFER is the first phase of a larger SAFER program whose objectives are to establish a common set of requirements for both space shuttle and space station program needs, develop a flight demonstration of SAFER, validate system performance and, finally, develop a production version of SAFER for the shuttle and station programs.
