Telstar I, volume 1

NASA Special Publication SP-32 is being published in accordance with the cooperative agreement executed on July 27, 1961 between the National Aeronautics and Space Administration and the American Telephone and Telegraph Company for the development and experimental testing of active communications satellites. This report consists of four volumes. The first three are composed of papers originally published together as a regular issue of the Bell System Technical Journal. The fourth volume, to be published at a later date, will contain pertinent papers contributed by various authors at the NASA Goddard Space Flight Center; the General Post Office of the United Kingdom; the Centre National d'Etudes des Telecommunications, France; and Telespazio, Italy.

The precision tracker

The precision tracker, a simultaneous lobing, amplitude-comparison, passive, continuous-wave tracker based in principle and design upon a monopulse tracking radar, is employed at the Andover, Maine, and Pleumeur-Bodou, France, stations to find the satellite and direct the horn-reflector antennas when required and, at regular intervals during subsequent passes, to provide the precise tracking data required for prediction of future orbital parameters.

Manned Space Flight Experiments Symposium: Gemini Missions III and IV

This is a compilation of papers on in-flight experiments presented at the first symposium of a series, Manned Space Flight Experiments Symposium, sponsored by the National Aeronautics and Space Administration. The results of experiments conducted during the Gemini Missions III and IV are covered. These symposiums are to be conducted for the scientific community at regular intervals on the results of experiments carried out in conjunction with manned space flights.

Arylenesiloxane copolymers

Arylenesiloxane copolymers with regularly ordered structures were discovered during efforts to develop organosilicon polymers. Arylenesilane and siloxane monomers were both synthesized in these experiments.

Design concept for nonarcing electrical connector

Connector plug automatically minimizes arcing during mating and demating. This plug uses a high-resistivity outer sheath as an extension to the regular pin contact. It is used in atmospheres containing explosive gases, and reduces erosion at the contact surfaces where mating and demating are performed frequently.

Ultra-high-flux heat exchanger

Spherical depressions on the wall of the inner tube increase the heat flux in a concentric tube heat exchanger. Regularly spaced patterns of precisely formed depressions on the inner wall alleviate the film-binding phenomenon without significantly degrading the flow characteristics.
