The SCU contains lines for power, communicati on s , oxygen and water re ch a r g e, and waterdrainage. The SCU conserves PLSS consumablesduring EVA preparation.9. Lower TorsoSpacesuit pants, boots, and the lower half of theclosure at the waist.The lower torso also has a waistbearing for body rotation and mobility, and D ringsfor attaching a safety tether.6.BatteryBattery that supplies electrical power for the EMUduring EVA.The battery is rechargeable in orbit.Hard UpperTorso underneathfabric7. Contaminant Control Cartridge (CCC)Cleanses suit atmosphere of contaminants with anintegrated system of lithium hydroxide, activatedcharcoal, and a filter contained in one unit. TheCCC is replaceable in orbit.Lower TorsoReference Numbers 8–11.8. Hard Upper Torso (HUT)Upper torso of the suit, c omposed of a hard fiberglassshell . It provides stru c t u ral support formounting the PLSS, DC M , a rm s , h e l m e t , I n - Su i tDrink Bag, EEH , and the upper half of the waistcl o s u re . The HUT also has prov i s i ons for mountinga mini-work s t a t i on tool ca r ri e r.10. Arms (left and right)Shoulder joint and shoulder bearing, upper armbearings, elbow joint, and glove-attaching closure.11. EVA Gloves (left and right)Wrist bearing and disconnect, wrist joint, and fingers.Thegloves have loops for attaching tethers forrestraining small tools and equipment. Generally,crew members also wear thin fabric comfort gloveswith knitted wristlets under the EVA gloves.2 0 • Suited for Spacewalking An Activity Guide for Technology Education, Mathematics, and Science, EG- 1 9 9 8 - 0 3 - 1 1 2 - H Q
12.HelmetPlastic pressure bubble with neck disconnect ringand ventilation distribution pad. The helmet has abackup purge valve for use with the secondary oxygenpack to remove expired carbon dioxide.14.Maximum Absorption Garment (MAG)An adult-sized diaper with extra absorption materialadded for urine collection.1 3 . Liquid Cooling-and-Ve n ti l a tion Garm e n t(LCVG)Long underwear-like garment worn inside thepressure layer. It has liquid cooling tubes, gas ventilationducting, and multiple water and gas connectorsfor attachment to the PLSS via the HUT.15. Extravehicular Visor Assembly (EVA)Assembly containing a metallic-gold-covered Sunfilteringvisor, a clear thermal impact-protectivevisor, and adjustable blinders that attach over thehelmet. In addition, four small “head lamps” aremounted on the assembly; a TV camera-transmittermay also be added.16.In-Suit Drink Bag (IDB)Plastic water-filled pouch mounted inside theHUT.
