Prospects for manned Mars missions

Studies called "EMPIRE" (standing for Early Manned Planetary-Interplanetary Roundtrip Expeditions) were initiated early in 1962 by the Future Projects Office for the Marshall Space Flight Center. These and related studies by other NASA centers were intended to bring to light the technical problems associated with such missions. The emphasis of these studies was on single and multiple planetary fty-bys, with some consideration given to planetary orbital and landing missions. The time period considered was the early 1970's. The contractors were Aeronutronic Division (Philco-Ford Motor Company), Lockheed Missiles and Space Company and General Dynamics/Astronautics. Studies relating to the time period 1975-85 were initiated in early 1963, by contracts with General Dynamics/ Fort Worth and Douglas Aircraft Company. Follow-on EMPIRE studies were carried out by Lockheed and General Dynamics/Astronautics. In addition, studies were made of a Mars Excursion Module by Aeronutronic, a Mars Mission Module (MMM) by North American Aviation's Space and Information Division, and an Earth Return Module (ERM) by Lockheed under the direction of the Manned Spacecraft Center. Complementary to these efforts were studies initiated by the Ames Research Center early in 1963 for a Manned Mars Landing and Return Mission. These studies were conducted by North American Aviation and by the TRW Space Technology Laboratories.
