  Wow. It's crazier than I realized! I always wished it at least included the orbiter name in it. But I suppose the orbiter choice could change closer to actual launch. STS-41B-ATL2

It's doubly confusing that STS-51-F, with the Challenger, is the only exercised launch abort; while STS-51-L is the famous launch disaster for which Challenger is most well known.

I think I know this: the F means it doesn’t have an igpu, right?

Shuttle missions began and ended with simple numeric designators (STS-1, STS-2 ... STS-135). In between was the above system, because of triskaidekaphobia. <https://en.wikipedia.org/wiki/List_of_Space_Shuttle_missions#Flight_numbering https://en.wikipedia.org/wiki/List_of_Space_Shuttle_missions...>

  To be fair, the previous history of American space missions numbered 13 did have a 100% rate of near-catastrophic failure...

    technically, sts-13 was a catastrophic failure, but they also technically renamed it.

      STS-13 was renamed to STS-41-C which was a reasonably routine mission.

        you're right, my mistake. I was thinking of a different mission by that particular shuttle

I guess computer science doesn’t have a monopoly over the difficulty of naming things.
