It was then moved to its the Destiny laboratory. location in the Destiny laboratory, where it was subject to Class 100,000 protected environment experiment facility the on-orbit commissioning. After successful conclusion of BACKGROUND this phase, it was ready to start its operational life. The design and development of the MSG has evolved substantially from the former Spacelab and Middeck The Microgravity Science Glovebox is an International Standard Payload Rack size facility where experiments in the field of Experiments can be launched/retrieved within stowage Gloveboxes that have been flown on numerous Space material science, biotechnology, fluid science, combustion science and crystal growth research can be conducted in a closed drawers (EXPRESS Racks or Re-supply/Stowage Racks) or Shuttle missions and on the Mir space station. and protected environment.

International OPERATIONAL CONCEPT Standard Payload Rack The MSG can operate in an open mode, with air circulating The MSG has been designed as a modular multi-user facility from the working volume to the MSG rack interior and for performing a wide variety of materials, combustion, in a closed mode, with air circulating within the MSG fluids and biotechnology investigations in the microgravity working volume only. Further, the MSG has the capability environment. Primarily it provides an enclosed and sealed to maintain in the working volume an inert atmosphere Work Volume equipped with lighting, mechanical, electrical, with dry nitrogen such that the oxygen volume is kept data, gas and vacuum connections, and thermal control. equal or less than 10%.
