All human space missions, regardless of destination, require significant logistical mass and volume. The amount required is a function of the mission duration. Reducing this logistical mass and volume by reusing items that would otherwise become trash can reduce launch weight and mission costs. During the summer of 2012, the Forward Osmosis Bag (FOB) flown on STS-135 in July 2011 was redesigned to improve overall efficiency of the fresh water production from grey water sources and to implement as part of the International Space Station (ISS) Crew Transfer Bags (CTB). CTBs are fabric cargo containers, which conform to specific dimensional and material requirements for space flight. This poster describes the development of a Forward Osmosis Crew Transfer Bag (FO-CTB) that can be reused on orbit to provide radiation shielding and water recycling capacity. The design, construction, and testing of several prototype versions of FO-CTB are discussed. It has not yet been determined which design will be pursued for implementation.
