STS-50 (U.S. Microgravity Laboratory-1) was a NASA Space Shuttle mission, the 12th mission of the Columbia orbiter. Columbia landed at Kennedy Space Center for the first time ever due to bad weather at Edwards Air Force Base caused by the remnants of Hurricane Darby .

In June 1992, the USML-1 Spacelab mission -- designated STS-50 -- will be launched into a 160-nautical-mile orbit aboard the Space Shuttle Columbia. It will be a 13-day mission to perform scientific investigations using some of the latest high-technology research equipment.

1992年6月25日 · Supporting the overall program objective, the STS-50 mission provided additional data on the polymer precipitation process-1. By analyzing the composition and the atomic structure of crystals grown without the dominating influence of gravity, scientists will gain insight into correlations between fluid flows during solidification and the ...

STS-50 not only marked the first U.S. Microgravity Laboratory flight, but also the first Extended Duration Orbiter flight. To prepare for long-term (months) microgravity research aboard Space Station Freedom, scientists and NASA need practical experience in managing progressively longer times for their experiments.

STS-50 was the first flight of the regenerable C02 removal subsystem (RCRS). The RCRS was activated shortly after orbital insertion and operated satisfactorily for the first 25 hours of the mission. The RCRS uses regenerable solid amine to adsorb C02 and water from the Orbiter cabin environment instead of non-regenerable lithium hydroxide (LiOH).
