1983 - Aboard OV-099 Challenger, Astronauts Story Musgrave and Don Peterson perform the shuttle program’s first EVA during mission STS-6. One can see clearly the hand-holds integrated into the payload bay for Astronauts to utilize on spacewalks. 

STS-6 was Challenger’s maiden flight, launching 3 days earlier on April 4th. The first Tracking and Data Relay System satellite (TDRS) was also deployed during STS-6.
