STS064-60-012 (16 Sept. 1994) --- Backdropped against the blackness of space and Earth's horizon 130 nautical miles below, astronaut Mark C. Lee (right) floats freely as he continues to test the new Simplified Aid for EVA Rescue (SAFER) system while converging with astronaut Carl J. Meade. Meade's feet are anchored to the space shuttle Discovery's remote manipulator system arm. The image was exposed with a 35mm camera from the shirt-sleeve environment of the space shuttle. Astronauts Lee and 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.
