The pilot's role in manned space flight

The present investigation regarding the pilot's role in manned space flight takes into account space missions conducted with the Mercury capsule, Gemini, Apollo, Skylab, and the Shuttle. It is concluded that advancements in digital systems and automation technology have made many of the space pilot's tasks easier. However, these advancements have also made the space pilot's training more complicated. He must be familiar with the interrelated failure effects in highly complex vehicle systems. The nominal performance of the Shuttle fly-by-wire entry control system depends, for instance, on nominal electrical power from three fuel cells, nominal performance of three hydraulic auxiliary power units, five computers, other equipment, and microwave landing systems. The pilot must monitor and manage failures in these systems, and, in addition, must be prepared to intervene if an abort situation creates off-nominal conditions.

SOLID PROPELLANT BOOSTERS FOR MANNED SPACE FLIGHT

Within the past year, large solid propellant rocket motors have become very prominent in discussions of possible launch vehicles for manned space flight. This is partly due to active promotion by the solid propellant rocket industry. The role that large solid rockets may play in space launching vehicles is also indicated, however, by the results of numerous analyses and vehicle studies that have been made in the past two years by government and other unbiased agencies. The promise of the large solid rocket motor has been further substantiated by major development accomplishments which have been achieved in the past year. The purpose of this paper is to review some of the reasons for the dramatic entry of large solid propellant boosters into the manned space flight field, to assess their present position, and to discuss some areas where need for further work is indicated.

LIQUID PROPELLANT LAUNCH VEHICLES FOR MANNED SPACE FLIGHT

Launch vehicle technology has probably been the most controversial aspect of the manned space flight program as it has developed during the past twelve months. This paper is a hopefully concise exposition of the present lunar flight system concept, and necessarily represents the concerted efforts of numerous individuals within government and industry who are engaged in the Apollo/Saturn program, and whose substantial contributions must be acknowledged at the outset.

Man, space flight and medicine.

Review of experience obtained from space flight to evaluate man's physiological capability to function in space. Results of the Mercury, Gemini, and Apollo programs are presented, with emphasis on the latter. The space medicine requirements which were necessary for assuring man's safe journey into and return from space have resulted in hardware and techniques of great value to terrestrial medicine. The need to monitor the physiologic function of crewmen led to the development of miniaturized, nonirritating, and highly reliable sensors.

Manned space flight nuclear system safety. Volume 7: Literature review. Part 1: Literature search and evaluation

A review of the literature used in conducting the manned space flight nuclear system safety study is presented. The objectives of the presentation are to identify and evaluate for potential application to study the existing related literature and to provide the information required to include the related literature in the NASA Aerospace Safety Research and Data Institute. More than 15,000 documents were evaluated and identification forms were prepared for 850 reports.
