STS-51F

For Story Musgrave, the flight engineer on Challenger’s Mission 51F, his ascent to orbit on 29 July 1985, was arguably dramatic, when the shuttle suffered a hair-raising main engine shutdown 108 km above Earth … after already enduring its own RSLS abort on the pad, three weeks earlier. “The ground made the call ‘Limits to Inhibit’,” he recalled to a Smithsonian interviewer, years later, “which is, for us, an extremely serious omen, [because it] means the ground is seeing problems that are going to shut you down.

‘I Wouldn’t Call it Fear’: The Shuttle Launch Pad Aborts (Part 2)
by Ben Evans March 30, 2014


The closest the shuttle ever came to a launch at the time of abort was T-1.9 seconds, on 18 August 1994. So close was the shuttle to launch, the on-board General Purpose Computers had already moded to their 102 ascent software configuration at the time of the abort. Photo Credit: NASA
