1992-034A
STS-50 was launched on 1992 Jun 25. It was the first flight with the EDO cryogenics pallet to provide extra electrical power and oxygen, supporting the USML-1 Spacelab mission. The first landing attempt on Jul 8 at Edwards was waved off due to bad weather.
The USML included a crystal growth facility capable of processing samples up to 1850K. The Drop Physics Module studied coalescence of fluid drops and a compound drop with one fluid inside another. A new `glovebox' mini-laboratory was used for fluid physics and crystal growth experiments.
