STS-4 was the fourth NASA Space Shuttle mission, and also the fourth for Space Shuttle Columbia. Crewed by Ken Mattingly and Henry Hartsfield, the mission launched on June 27, 1982, and landed a week later on July 4, 1982. Due to parachute malfunctions, the SRBs were not recovered.
STS-4 was the final test flight for the Space Shuttle; it was thereafter officially declared to be operational. Columbia carried numerous scientific payloads during the mission, as well as military missile detection systems.
