STS-51-F Abort-to-Orbit (1985)

Wikipedia recounts NASA's 1985 STS-51-F Challenger mission, the shuttle program's only Abort-to-Orbit.

The Wikipedia page describes STS-51-F, the 19th Space Shuttle flight and the eighth mission of Challenger, launched on July 29, 1985. A failed center-engine sensor forced the program's only Abort-to-Orbit, and the crew flew a lower orbit than planned. The primary payload was Spacelab 2, alongside astronomy instruments and a carbonated-beverage experiment. The page is historical spaceflight material, not cybersecurity or AI news.
