Space Station - The first step

The United States Space Station program, begun in Fiscal Year 1985 under significant cost constraints, should cause all those involved in the planning of manned interplanetary flight to revise their impressions of the cost and practicality of planetary missions. The presence of the Space Shuttle, as well as arrival of a capable Space Station, will provide a major impetus to planetary programs, both by removing most of the real barriers to extended manned space flights and by proving that significant manned space ventures may be performed very economically.

The cost of landing man on Mars

In a period where the space program budget is generally static at about 1/3 of the level reached during the Apollo program, manned planetary flight is not considered by NASA planners to be a realistic near term goal. Much of NASA's current planning is based on the perception that manned planetary flight would be more costly than the Apollo lunar landing. This paper demonstrates that with current technological improvements in avionics, structure, and space transportation, the landing of an American on Mars would cost only 1/3 to 2/3 of the lunar landing; on a per capita basis such a program would cost less than $200, compared to Apollo's $325 (all dollars in 1981 base). Given the fact that a manned Mars landing is the last such exploration feat left to this generation, the cost should clearly not be a major deterrent.
