Nodes Packaging Option for Space Station Application 881035

Space Station nodes packaging analyses are presented relative to moving environmental control and life support system (ECLSS) equipment from the habitability (HAB) module to node 4 in order to provide more living space and privacy for the crew, remove inherently noisy equipment from the crew quarter, retain crew waste collection and processing equipment in one location, and keep objectionable odor away from the living quarters. In addition, options for moving external electronic equipment from the Space Station truss to pressurized node 3 were evaluated in order to reduce the crew extravehicular activity (EVA) time required to install and maintain the equipment. Node size considered in this analysis is 3.66 m (12 ft) in diameter and 5.38 m (17.67 ft) long. The analysis shows that significant external electronic equipment could be relocated from the Space Station truss structure to node 3 and non-life critical ECLSS HAB module equipment could be moved to node 4.
