Lee floats free as he tests the new SAFER (Simplified Aid for EVA Rescue) system. The image was exposed with a 35 mm camera in the environment of the Space Shuttle Discovery. Astronauts Lee and Carl J. Meade took turns using the SAFER equipment during their joint EVA on September 16, 1994. The SAFER test is the first phase of a larger SAFER program whose objectives are to establish a common set of requirements for the Shuttle and Space Station programs, to develop a flight demonstration of SAFER, to validate the system's performance and, finally, to develop a production version of SAFER for the Shuttle and Space Station programs.
