Launch from Cape Canaveral (KSC); landing Cape Canaveral (KSC)

This was the reflight of mission STS-83 (Microgravity Science Lab). MSL was a collection of microgravity experiments housed inside a European Spacelab Long Module (LM). MSL featured 19 materials science investigations in 4 major facilities. These facilities were the Large Isothermal Furnace, the EXpedite the PRocessing of Experiments to the Space Station (EXPRESS) Rack, the Electromagnetic Containerless Processing Facility (TEMPUS) and the Coarsening in Solid-Liquid Mixtures (CSLM) facility, the Droplet Combustion Experiment (DCE) and the Combustion Module-1 Facility. Finally the crew performed experiments with flame balls. There were also experiments on measuring microgravity. They included the Space Acceleration Measurement System (SAMS), the Microgravity Measurement Assembly (MMA), the Quasi-Steady Acceleration Measurement System and the Orbital Acceleration Research Experiment (OARE).
