Zero-Gravity Atmospheric Cloud Physics Experiment Laboratory engineering concepts/design tradeoffs. Volume 1: Study results

The work is summarized which was accomplished from January 1974 to October 1974 for the Zero-Gravity Atmospheric Cloud Physics Laboratory. The definition and development of an atmospheric cloud physics laboratory and the selection and delineation of candidate experiments that require the unique environment of zero gravity or near zero gravity are reported. The experiment program and the laboratory concept for a Spacelab payload to perform cloud microphysics research are defined. This multimission laboratory is planned to be available to the entire scientific community to utilize in furthering the basic understanding of cloud microphysical processes and phenomenon, thereby contributing to improved weather prediction and ultimately to provide beneficial weather control and modification.

Development of a biowaste resistojet propulsion system propellant management and control subsystem.

The subject subsystem is under development as the major portion of an overall biowaste resistojet system development program. The design is based on the Space Station model, but incorporates features compatible with all envisioned/anticipated advancements in the interfacing environmental control life support (EC/LS) system. Results to date, for system design, development plan, component selection, and system acceptance test will be presented. Subsystem usage in functional system tests to be performed at Langley Research Center, and its application to an envisioned and integrated system, and extended manned tests, are delineated. Expanded applications of the subsystem, to control/limit external contamination of manned spacecraft, are identified.-
