Astronaut Mark Lee floats free of tether during EVA

STS064-45-028 (16 Sept. 1994) --- Astronaut Mark C. Lee, STS-64 mission specialist, tests the new Simplified Aid for EVA Rescue (SAFER) system 130 nautical miles above Earth. The forward cargo bay is reflected in Lee's helmet visor in the 35mm frame, exposed through the space shuttle Discovery's aft flight deck windows. Part of the hardware for the LIDAR-in-Space Technology Experiment (LITE) is in center foreground. Astronauts Lee and Carl J. Meade, mission specialist, 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.
