Astronauts Meade and Lee test SAFER system during EVA

Astronauts Carl J Meade and Mark C Lee (red strip on suit) test the new Simplified Aid for EVA Rescue (SAFER) system some 130 nautical miles above Earth during NASA's Mission STS-64, 16th September 1994. The pair was actually performing an in-space rehearsal or demonstration of a contingency rescue using the never-before flown hardware. Meade, who here wears the small back-pack unit with its complementary chest-mounted control unit, and Lee (anchored to the Space Shuttle Discovery's Remote Manipulator System (RMS) robot arm) took turns using the SAFER hardware during their shared space walk.
