msl-1

The primary payload on STS-83 was the Microgravity Science Laboratory (MSL). MSL was a collection of microgravity experiments housed inside a European Spacelab Long Module (LM).
MSL featured 19 materials science investigations in four 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. Additional technology experiments were to be performed in the Middeck Glovebox (MGBX) developed by the Marshall Space Flight Center (MSFC) and the High-Packed Digital Television (HI-PAC DTV) system was used to provide multi-channel real-time analog science video.

The Large Isothermal Furnace was developed by the Japanese Space Agency (NASDA) for the STS-47 Spacelab-J mission and was also flown on STS-65 IML-2 mission. It housed the measurement of diffusion coefficient by shear cell method experiment, the diffusion of liquid metals and alloys experiment, the diffusion in liquid led-tin-telluride experiment, the impurity diffusion in ionic melts experiment, the liquid phase sintering II experiment (LIF), and the diffusion processes in molten semiconductors experiment (DPIMS).

This version has some variations from another STS-83 MSL patch.

STS-83 was a mission of the United States Space Shuttle Columbia. This mission was originally launched on 4 April 1997, and was intended to be on orbit for 15 days, 16 hours. The mission was cut short due to a problem with Fuel Cell #2 and it landed on 8 April, after 3 days 23 hours. NASA decided to fly the mission again as STS-94, which launched 1 July 1997.
The primary payload on STS-83 was the Microgravity Science Laboratory (MSL). MSL was a collection of microgravity experiments housed inside a European Spacelab Long Module (LM). It built on the cooperative and scientific foundation of the International Microgravity Laboratory missions (IML-1 on STS-42 and IML-2 on STS-65), the United States Microgravity Laboratory missions (USML-1 on STS-50 and USML-2 on STS-73), the Japanese Spacelab mission (Spacelab-J on STS-47), the Spacelab Life and Microgravity Science Mission (LMS on STS-78) and the German Spacelab missions (D-1 on STS-61-A and D-2 on STS-55).

The EXpedite the PRocessing of Experiments to Space Station (EXPRESS) Rack is a Space Station International Standard Payload Rack (ISPR) being flown on MSL-1 as a precursor payload. The Spacelab program provides the structure and subsystem hardware to accommodate the EXPRESS Rack with interfaces like those on Space Station. Flown on STS-95 aboard the Microgravity Science Laboratory (MSL-1)

The Combustion Module-1 (CM-1), NASA's largest (over 1800 lb) and one of the most sophisticated combustion experiments ever to fly on the Spacelab, will be carried on the first Microgravity Science Laboratory (MSL-1) mission aboard the space shuttle flight STS-83 in April 1997. The combustion module 1 (CM-1) is being developed to accommodate microgravity combustion experiments designed to help explain and predict the behavior of combustion processes. CM-1 is planned for flight in the Microgravity Science Laboratory 1 (MSL-1) Spacelab module

Intended for STS-83, but was reflown on STS-94 after mission was ended prematurely.

The Physics of Hard Spheres Experiment (PHaSE) is a NASA Lewis Research Center fluid physics space flight experiment whose purpose is to investigate the behavior and physical properties of a colloidal dispersion of hard spheres. The Microgravity Science Division of the NASA Lewis Research Center has the responsibility of implementing the PHaSE space flight experiment. Onboard STS-94 and STS-83 MSL-1.

The National Aeronautics and Space Administration's (NASA 's) Protein Crystal Growth (PCG) program has been developed to learn how protein crystals grow in space and how to optimize the growth process, while producing large, high-quality crystals of selected proteins. Flown onboard MSL-1 on STS-94, STS-57, STS-60, STS-62, STS-95
