Description
Paul G Marcotte at Goddard Space Flight Center prepared this January 1964 feasibility study. It asks whether Interplanetary Monitoring Platform spacecraft, called IMP D and IMP E, could be placed in orbit around the Moon. The craft would weigh about one hundred eighty-one pounds.
Marcotte reports that the plan could work. A thrust-augmented Delta rocket with an extra third stage and a retrorocket could do the job. In the improved case, the chance of a stable lunar orbit was better than ninety percent. The study gave planners a concrete option, with odds stated plainly.
