Grumman submitted to NASA its final report on a study of AES for Earth-orbit missions (conducted under the firm's contract for a LEM utilization study). The five-volume report comprised general engineering studies, mission and configuration descriptions for different groups of experiments (both NASA's and those for the Air Force's Manned Orbiting- Laboratory), and a cost and schedule analysis.
Grumman's basic LEM utilization study explored potential uses for that vehicle beyond the initial Apollo lunar landing and examined several configurations, including a LEM laboratory for extended stays in Earth or lunar orbits; the LEM shelter, an unmanned logistics vehicle to afford astronauts a separate shelter for extended stays on the lunar surface; the extended LEM, a personnel carrier to be used in conjunction with the LEM shelter missions; and a LEM truck, an unmanned logistics vehicle without the ascent stage, thus affording an even greater payload capability to the lunar surface.) The scope of this addition to the basic study concerned the value of the LEM lab in conjunction with the command and service module for Earth-orbiting missions as part of the AES program. The study included spacecraft and experiment definition, as well as cost and schedule analyses; the description of spacecraft configurations to accommodate various types of experiments; and an analysis of crew procedures and operational requirements.
