Outer atmospheric research - One tether capability

One specific tether application of far-reaching promise would be to conduct outer atmospheric research by using a tethered subsatellite deployed downward from an orbiting 'mother' craft such as the Shuttle Orbiter. This capability would gather scientific and engineering/technology information about the outer atmosphere, primarily from 150 km down to perhaps 90 km. This paper presents current determinations of specific user needs, tether capabilities, and technological and program requirements to fulfill this application of tethers in space.

A systems engineering view of the human in space

A model of the human as an 'engineered' system provides a starting point for determining human requirements and performance on an equivalent basis with technological systems. The human as an engineered system with performance requirements is defined to consist of four subsystems: cognitive, psychological, biomechanical, and biomedical. It is suggested that the treatment of the psychological subsystem as one that modulates the efficiency and quality of human performance offers a particular approach for examining and characterizing psychological effects.

Technology and applications - Convergence to a tether capability

In this paper, a convergence of interest from many potential tether applications is synthesized into one application that could be satisfied by a tethered satellite capability. This application is the use of a tethered research satellite deployed downward from the Shuttle Orbiter to gather scientific and engineering/technology data about the outer atmosphere from about 90 to 130 km. The atmospheric and aerothermodynamic information needed about this region of the atmosphere is identified, and the specific applications of that information, the tether capability, and the technology needed to gather the data are described.
