Astronauts Mark C. Lee (left) and Carl J. Meade were photographed in the midst of 15-minute pre-breathe exercise in preparation for their Extravehicular Activity (EVA) of Sept. 16, 1994. On that day the two performed an in-space rehearsal or demonstration of a contingency rescue using the never-before flown Simplified Aid for EVA Rescue (SAFER) system some 130 nautical miles above Earth. During the EVA the two STS-64 mission specialists took turns using the SAFER hardware. The test was the first phase of a larger SAFER program leading finally to the development of a production version for future shuttle and space station applications.
