At the request of NASA Hq, MSC contracted with North American to determine what engineering modifications to the basic Apollo spacecraft would be required to extend that vehicle's mission capabilities to a 100-day orbital lifetime.
Although the study contract was handled chiefly by the Space Vehicle Design Branch of the Spacecraft Technology Division, Engineering and Development Director Maxime A. Faget requested that all elements of his directorate lend support as required to achieve a meaningful and useful effort, including in-house study efforts if needed. Also, Faget described the vehicle model that served as the basis for the study: a space laboratory for either a two or three-man crew; an orbital altitude of from 160 km to 480 km; an orbital staytime of about 100 days without resupply; and launch aboard a Saturn IB. He stated that two separate vehicles were under consideration, an Apollo command module and a command module and separate mission module to be used as living quarters.
