📅 On This Day in Aviation History — September 5, 1984
On this day in 1984, a new chapter in American spaceflight touched down on a California dry lakebed.
At 6:37 a.m. PDT, Space Shuttle Discovery landed at Edwards Air Force Base, successfully completing STS-41D—its very first mission into space.
Over six days, Discovery and its six-person crew circled Earth 97 times and traveled approximately 2.5 million miles. Along the way, they deployed three communications satellites and put an unusual piece of technology through its paces: a lightweight experimental solar array that unfurled to more than 100 feet in length from a remarkably compact container in the Shuttle's payload bay. The experiment tested lightweight, deployable solar-array technology envisioned for powering large future structures in orbit.
The mission also carried another piece of aviation and space history. Charles D. Walker became the first commercial payload specialist to fly aboard the Shuttle, operating a McDonnell Douglas biotechnology experiment during the mission.
And if some of STS-41D looks unusually cinematic in archival footage, there's a reason for that. The crew carried an IMAX camera into orbit and filmed satellite deployments, experiments, and life aboard Discovery. Some of that footage later appeared on enormous theater screens in the 1985 IMAX film The Dream Is Alive.
After six days, Commander Henry 'Hank' Hartsfield Jr. brought Discovery down on Runway 17 at Edwards, bringing Discovery's maiden voyage to a successful conclusion.
It turned out to be just the beginning.
Discovery ultimately completed 39 missions, more than any other Space Shuttle. During that remarkable career, it would deploy the Hubble Space Telescope, carry John Glenn back into orbit, and fly both of NASA's "Return to Flight" missions following the Challenger and Columbia tragedies.
But all 39 missions started with STS-41D—and on September 5, 1984, Discovery proved for the first time that it could make the journey to orbit and safely come home again. 🚀
Aviation Trivia: Discovery was NASA's third space-qualified orbiter to join the Shuttle fleet. Can you name the two orbiters that flew before it?
