An overview of United States manned space flight from Mercury to the Shuttle

Technical considerations in the design, development and operation of United States manned spacecraft from Project Mercury to the Space Shuttle are reviewed. The design and mission philosophies, launch vehicle and spacecraft characteristics, mode of operation, flight results and influence on later programs are discussed for Project Mercury, and Gemini Apollo and Skylab programs, the Apollo-Soyuz Test Project and the Space Shuttle program. The Space Shuttle is shown to represent a major departure from the trend established in previous programs, requiring major advancements in the fields of flight control, thermal protection, and liquid-propellant rocket technology.

Effects of prolonged exposure to pure oxygen on human performance

In view of the pure oxygen atmosphere selected for Project Mercury, and in anticipation of subsequent manned space missions of increasing duration, it was apparent that there was a need to obtain more extensive physiological data on the prolonged effects of pure oxygen environments on the crews. This study, conducted by Republic Aviation Corporation under Contract NASR-92, was initiated in collaboration with General Charles Roadman, USAF (MC), Director of Aerospace Medicine (formerly the Office of Life Sciences, NASA Headquarters), and his staff in an effort to provide a greater breadth of scientific data on the prolonged effects of such an environment on human performance. Although the 5 psi environment of Project Mercury was the focal point of the study, a broader appraisal of the effects of pure oxygen in the absence of nitrogen was attempted by including studies at 7.4 psi and 3.8 psi in addition to a control group at sea level atmospheric conditions. After award of the contract, the technical monitoring of the study was provided by the Manned Spacecraft Center, Houston, Texas, where Mr. Edward Michel served as monitor and coordinator for these and related studies subsequently established in laboratories of the U.S. Navy and U. S. Air Force.

FLIGHT EXPERIENCES IN THE MERCURY PROGRAM

At this time, the National Aeronautics and Space Administration (NASA) has successfully completed five manned space flights in Project Mercury. Two of these were suborbital, and of approximately 19 minutes duration, and each of these subjected the pilot to about 5 minutes of weightlessness. The remaining three manned flights were orbital. Two of these flights involved the completion of three orbital passes, or about hours of weightlessness. The last orbital flight was extended to six orbital passes with nearly 10 hours of weightlessness. As a result of these flights, we have gained a wealth of information about space and man's ability to function in this new environment. There is, however, much which is yet to be learned regarding both of these aspects.
