Procedure for Failure Mode, Effects, and Criticality Analysis (FMECA)

This document provides guidelines for the accomplishment of Failure Mode, Effects, and Criticality Analysis (FMECA) on the Apollo program. It is a procedure for analysis of hardware items to determine those items contributing most to system unreliability and crew safety problems.

Analysis of inflight sleep, experiment M008

The feasibility of recording the electroencephalogram during space flight is demonstrated. The precise information that is collected with the electroencephalograph regarding the duration, depth, and number of sleep periods implies that electroencephalogram monitoring should be considered for routine use in the long-duration space flights that are contemplated for the Apollo Program and other programs. The importance of such information in the direction and execution of the flight, both to the medical monitors and to the crewmembers, is obvious.

Apollo experience report: Acceptance checkout equipment for the Apollo spacecraft

The acceptance checkout equipment for the Apollo spacecraft is described, and the history of the major equipment modifications that were required to meet the Apollo Program checkout requirements is traced. Some major problem areas are outlined, and a discussion of future checkout methods is included. The concept of the future checkout methods presented provides for an increase in test equipment standardization among NASA programs and among all testing phases within a program. The capability for increased automation and reduction in the test equipment inventory is provided in the proposed concept.

Apollo experience report: Crew provisions and equipment subsystem

A description of the construction and use of crew provisions and equipment subsystem items for the Apollo Program is presented. The subsystem is composed principally of survival equipment, bioinstrumentation devices, medical components and accessories, water- and waste-management equipment, personal-hygiene articles, docking aids, flight garments (excluding the pressure garment assembly), and various other crew-related accessories. Particular attention is given to items and assemblies that presented design, development, or performance problems: the crew optical alinement sight system, the metering water dispenser, and the waste-management system. Changes made in design and materials to improve the fire safety of the hardware are discussed.

Soil mechanics experiment

The Apollo 15 soil-mechanics experiment has offered greater opportunity for study of the mechanical properties of the lunar soil than previous missions, not only because of the extended lunar-surface stay time and enhanced mobility provided by the lunar roving vehicle (rover), but also because four new data sources were available for the first time. These sources were: (1) the self-recording penetrometer (SRP), (2) new, larger diameter, thin-walled core tubes, (3) the rover, and (4) the Apollo lunar-surface drill (ALSD). These data sources have provided the best bases for quantitative analyses thus far available in the Apollo Program.

Surface refractivity measurements at NASA spacecraft tracking sites

High-accuracy spacecraft tracking requires tropospheric modeling which is generally scaled by either estimated or measured values of surface refractivity. This report summarizes the results of a worldwide surface-refractivity test conducted in 1968 in support of the Apollo program. The results are directly applicable to all NASA radio-tracking systems.

Look to the future - NASA/Space.

The remainder of the Apollo program is considered, giving attention to an increased lunar stay time of about 3 days for the J series. The Skylab program is the second program, whose missions are fairly well outlined. There are three flights associated with it which are planned for 1973. The objectives of the flight are to study man, his performance, habitability, and medical responses. Solar and terrestrial studies are also planned. Other projects discussed include the Shuttle, an earth orbiting space station, a space tug, and deep space missions such as the exploration of Mars.

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.

Application of NASA management approach to solve complex problems on earth

The application of NASA management approach to solving complex problems on earth is discussed. The management of the Apollo program is presented as an example of effective management techniques. Four key elements of effective management are analyzed. Photographs of the Cape Kennedy launch sites and supporting equipment are included to support the discussions.

The relationship of NASA occupational medicine and environmental health with the Advisory Center on Toxicology

Preventive measures of occupational medicine and industrial hygiene are coordinated to identify toxicities of industrial products and safety standards in manned space flight applications. Emphasized is the off-gassing of construction materials in spacecraft with the resulting contamination of the cabin atmosphere and the establishment of criteria for the quality of drinking water for astronauts during Gemini and Apollo programs.
