American manned Mars expedition. Study 1964. Unfavorable Manned Planetary - Interplanetary Roundtrip Expedition profiles were studied under NASA Huntsville contracts to General Dynamics and Douglas in June 1963.
The studies looked at manned Mars missions at unfavorable mission opportunities (e.g. 1975, 1977). Convair concluded that only conjunction class long-duration 800-1000 day missions were feasible at such opportunities.
