Astronaut Bruce McCandless II, STS-41-B mission specialist, uses his hands to control his movement above the Earth — just a few meters away from the space shuttle Challenger — during the first-ever spacewalk which didn’t use restrictive tethers and umbilicals. Fellow crewmembers aboard the Challenger used a 70mm camera to expose this frame on Feb. 7, 1984, through windows on the flight deck. McCandless was joined by Robert L. Stewart, one of two other mission specialists for this flight, on two sessions of EVA.
