On April 7, 1983, astronauts took the first spacewalk outside of a space shuttle during mission STS-6. This was the maiden voyage of the space shuttle Challenger. The goal of this mission was to deploy the first Tracking and Data Relay Satellite, TDRS-1.

NASA now uses a whole fleet of these satellites to relay communications between spacecraft in orbit and ground stations down on Earth.
