30 lat temu, 08.04.1993 o 05:28:59,989 z wyrzutni LC-39B na Cape Canaveral wystartował wahadłowiec Discovery do misji
STS-56.
Był to 16. lot orbitalny Discovery.
Czas lotu: 9d 06g 08m 19s.
Głównym ładunkiem był ATLAS-2 (Atmospheric Laboratory for Applications and Science-2), który służył do badania oddziaływania cząstek wiatru słonecznego na ziemską atmosferę oraz do mierzenia wpływu różnych czynników na warstwę ozonową.
11.04.1993 przy pomocy
Canadarm został umieszczony poza orbiterem SPARTAN-201 (Shuttle Pointed Autonomous Research Tool for Astronomy) do badania wiatru słonecznego i obserwacji korony słonecznej.
Platforma naukowa została ponownie umieszczona na pokładzie wahadłowca 13.04.1993.
Został nawiązany po raz pierwszy kontakt radiowy między wahadłowcem a stacją kosmiczną Mir przy wykorzystaniu amatorskiego sprzętu radiowego.
Lądowanie zaplanowano na 16.04.1993, ale zostało odwołane z powodu pogody.
17.04.1993 o 11:37:19 Discovery wylądował na bieżni SLF (RW33) KSC .

The countdown on the night of 6 April proceeded smoothly until the built-in hold at T-9 minutes, when an issue arose relating to higher-than-expected temperatures on a valve in Discovery’s No. 1 SSME. The clock was held for more than an hour, before controllers finally resumed the count at 1:23 a.m. EDT on the 7th. (...)
At T-11 seconds, abruptly, the countdown was automatically halted and the launch attempt scrubbed. It subsequently became apparent that the hydrogen high-point bleed valve’s “closed” indicator was not present and—although the cause was traced to an instrumentation error, not a hardware malfunction—it breached Launch Commit Criteria (LCC) rules.

The box-shaped Spartan, which now resides on display at the National Air and Space Museum (NASM) in Washington, D.C., spent two days in free flight, observing the Sun’s corona. The crew performed three separation “burns” to back away from the payload to a distance of 100 miles (160 kilometers). (...)
All told, STS-56 gathered atmospheric data over 94 percent of Earth, including detailed stratospheric measurements of the Arctic Region. (...)
