The Microgravity Science Glovebox (MSG) is a glovebox aboard the International Space Station. It provides a safe contained environment for research with liquids, combustion and hazardous materials in the microgravity conditions of the ISS. Without the MSG, many types of hands-on investigations would be impossible or severely limited on board the Station. The Microgravity Science Glovebox (MSG) occupies a floor-to-ceiling rack inside the Destiny module of the International Space Station (ISS). It is more than twice as large as gloveboxes flown on the Space Shuttle and can hold larger investigations that are about twice the size of an airline carry-on bag. 〔http://www.nasa.gov/mission_pages/station/science/experiments/MSG.html Microgravity Science Glovebox (MSG) - NASA〕 ==Description== The Core Facility of MSG occupies the upper half of the overall rack and includes the large work volume (WV), an airlock and electronics for control, housekeeping and investigation resources. The WV holds the experiment and related equipment. The work volume is approximately 3 feet wide (906 mm), 2 feet high (637 mm), and 1.5 feet deep (442 mm) with a usable volume of about 255 litres. This area can be sealed and held at a negative pressure, isolating the crew and the Station from possible hazards associated with the investigations that are taking place inside. An airlock under the WV can be accessed to bring objects in safely while other activities are going on inside MSG. The MSG has 40 cm diameter side ports (equipped with rugged gloves that are sealed to prevent leaks) for setting up and manipulating equipment in the WV. A cold-plate provides cooling for experiment hardware and the air is continuously circulated and filtered. Experiments are provided with 1 kW of power and cooling. Vacuum, venting, nitrogen gas input (that can keep the oxygen volume at 10 percent or less), power and data interfaces are also provided within MSG. A video system consists of a self-standing subsystem of four colour cameras, two monitors, two analogue recorders and two digital recorders integrated into an International Sub-rack Interface Standard (ISIS) drawer. The command and monitoring panel monitors the facility status and performance and provides for manual operation of MSG by the crew. MSG was delivered to ISS during Expedition 5, whereupon it was installed in the Destiny module. On March 21 2008, during Expedition 16, MSG was relocated to the Columbus module.〔 On October 21 2010, during Expedition 25, MSG was transferred back to the Destiny module. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Microgravity Science Glovebox」の詳細全文を読む スポンサード リンク
