On Sept. 16, 1994, astronaut Mark C. Lee tested out the Simplified Aid for EVA Rescue (SAFER) system, a system designed for use in the event a crew member becomes untethered while conducting a spacewalk. Occurring during the STS-64 mission, this was the first untethered U.S. spacewalk in 10 years.
This SAFER test was the first phase of a larger SAFER program whose objectives were 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.
