An historical overview of NASA manned spacecraft and their crew stations

The first generation of manned spacecraft demonstrated all the types of mission activity planned for the future. Development of these spacecraft and execution of their missions have provided the experience base for the design of current and future spacecraft systems. This paper summarizes the crew station characteristics of the Mercury, Gemini, Apollo, Skylab, Apollo-Soyuz and Space Shuttle spacecraft and the design strategies that dictated those characteristics. Also included are some comparisons with current and planned spacecraft and an assessment of the lessons learned as they might be applied in future spacecraft designs.

Summary of radiation dosimetry results on U.S. and Soviet manned spacecraft

Measurements of the radiation environment aboard U.S. and Soviet manned spacecraft are reviewed and summarized. Data obtained mostly from passive and some active radiation detectors now exist for the case of low-earth-orbit missions. Major uncertainties still exist for space exposure in high-altitude, high-inclination geostationary orbits, in connection with solar effects and that of shielding. Data from active detectors flown in Spacelabs 1 and 2 suggest that a variety of phenomena must be understood before the effects of long-term exposure at the Space Station type of orbit and shielding can be properly assessed.

United States manned spacecraft reliability experience

Attention is given to the reliability controls in manned spacecraft programs, taking into account the project Mercury, the Gemini program, the Apollo program, the Skylab program, and the Apollo-Soyuz test project. Reliability controls used in these programs are related to reliability management, parts and materials control, failure mode and effects analysis, reliability quantitative analysis, problem reporting and corrective action control, test control, limited-life control, and milestone reviews. A summary is presented of the major reliability tasks and innovations being used on the Space Shuttle program. Examples of these innovations include improved management techniques and an early identification of specific certification tests.
