Space shuttle program: Shuttle Avionics Integration Laboratory. Volume 7: Logistics management plan

The logistics management plan for the shuttle avionics integration laboratory defines the organization, disciplines, and methodology for managing and controlling logistics support. Those elements requiring management include maintainability and reliability, maintenance planning, support and test equipment, supply support, transportation and handling, technical data, facilities, personnel and training, funding, and management data.

New technology from 100 ampere-hour Ni-Cd space battery program

The present paper describes some of the results of a 100 Ah battery development program. Background, module design, cell terminal design, and other technology newly used are described. It is shown that the program led to successful production of both cell and module, and that several areas utilized new technology and contributed advances to the sealed secondary battery state-of-the-art.

A study to define an in-flight dynamics measurement and data applications program for space shuttle payloads

Data measurement and interpretation techniques were defined for application to the first few space shuttle flights, so that the dynamic environment could be sufficiently well established to be used to reduce the cost of future payloads through more efficient design and environmental test techniques. It was concluded that: (1) initial payloads must be given comprehensive instrumentation coverage to obtain detailed definition of acoustics, vibration, and interface loads, (2) analytical models of selected initial payloads must be developed and verified by modal surveys and flight measurements, (3) acoustic tests should be performed on initial payloads to establish realistic test criteria for components and experiments in order to minimize unrealistic failures and retest requirements, (4) permanent data banks should be set up to establish statistical confidence in the data to be used, (5) a more unified design/test specification philosophy is needed, (6) additional work is needed to establish a practical testing technique for simulation of vehicle transients.

Large Space Telescope Program status

This paper provides an overview of the current status of the LST Program. The history of the program is treated briefly, with emphasis placed on the recent Phase B definition activity. The background and rationale leading to the decision of the aperture size of the LST primary mirror are discussed. The current technical definition status of the LST Optical Telescope Assembly and Support Systems Module is treated in a summary fashion. Key milestone events during the balance of the Phase B definition effort and schedule and over-all planning for the development phase of the program are described.

Space Shuttle Program Orbiter Approach and Landing Test

The orbiter approach and landing test (ALT) reports are published to provide senior NASA management with timely information on ALT program plans and accomplishments. The ALT reports will be comprised of this pre-ALT report, ALT pre-flight memoranda, and an ALT post-flight report following each flight. The purpose of this pre-ALT report is to provide an overview of the ALT program, describing the flight vehicles involved and summarizing the planned flights.

Guidelines for advanced manned space vehicle program, June 1960

A very broad mission objective was established; i.e., manned circumlunar flight and return to earth. It is implicit that the Saturn will be the primary propulsion system for this mission. The following attempts to: (1) define the objective so as to achieve as much capability in the vehicle as possible; (2) draw on Mercury experience to provide broad guidelines for vehicle performance and safety; (3) provide flexibility in the vehicle capability in the event that the manned lunar mission is proved to be subject to unacceptable risk in the target time period; and (4) indicate problem areas where work appears to be particularly needed.

Notes on Soviet space astronomy

Soviet space programs intended for making astronomical observations are reviewed. The Cosmos, Intercosmos, and Prognoz satellites designed for astronomical measurements are identified, and unmanned lunar and planetary missions are discussed, including the Luna, Lunokhod, Mars, and Venera programs. The Salyut 4 space station is described in detail along with the following major astronomical instruments: the Orbiting Solar Telescope 1, the infrared telescope spectrometer, the two solar spectrometers, the light-nuclei mass spectrometer, and the Filin and RT-4 X-ray telescopes. The future of Soviet space astronomy is assessed, particularly the tasks of the Salyut 5 station and the scheduled launch of Salyut 6.

TDRSS system configuration study for space shuttle program

This study was set up to assure that operation of the shuttle orbiter communications systems met the program requirements when subjected to electrical conditions similar to those which will be encountered during the operational mission. The test program intended to implement an integrated test bed, consisting of applicable orbiter, EVA, payload simulator, STDN, and AF/SCF, as well as the TDRSS equipment. The stated intention of Task 501 Program was to configure the test bed with prototype hardware for a system development test and production hardware for a system verification test. In case of TDRSS when the hardware was not available, simulators whose functional performance was certified to meet appropriate end item specification were used.

Biomedical application in space, pilot program in the southern California region

A pilot program is presented which was to promote utilization of the Shuttle/Spacelab for medical and biological research applied to terrestrial needs. The program was limited to the Southern California region and consisted of the following five tasks: (1) preparation of educational materials; (2) identification of principal investigators; (3) initial contact and visit; (4)development of promising applications; and (5) evaluation of regional program methodology.

The NASA Lewis Research Center program in space solar cell research and technology

Progress in space solar cell research and technology is reported. An 18 percent-AMO-efficient silicon solar cell, reduction in the radiation damage suffered by silicon solar cells in space, and high efficiency wrap-around contact and thin (50 micrometer) coplanar back contact silicon cells are among the topics discussed. Reduction in the cost of silicon cells for space use, cost effective GaAs solar cells, the feasibility of 30 percent AMO solar energy conversion, and reliable encapsulants for space blankets are also considered.
