Spacesuit insulation technologies protect the astronaut from extreme high and low temperatures of the space environment. However, the same insulation technology also works to keep heat released by the astronaut's body inside the suit. Imagine walking around in summer wearing a plastic bag. Because of this retained heat, an active cooling system is employed within the spacesuit. The two investigation activities in this Exploration Brief allow students to demonstrate the principle behind the operation of the space shuttle extravehicular mobility unit, or spacesuit. Students will also be able to experience the water-cooling technology of the EMU.
