Abstract : The work carried on under this contract was directed towards participation in the Aeronomy Laboratory's program devoted to the measurement of upper atmosphere density, temperature, and pressure through the medium of the free-falling sphere technique. Included therein were payload integration and field support for experimental rocket systems used to determine upper atmosphere density in the altitude region above 100 km, as well as the fabrication of the basic rocket payload hardware, such as special nose cones, upper and lower sphere holders, sphere ejection devices, radar transponder assemblies, and the transitions sections for mating the rocket and payload components. Also included were the improvement of the ground-based telemetry apparatus for the experimental payload, the investigation of devices for increasing the range and reliability of high altitude density measurements, participation in the launching of the rocket-borne experiments at sites designated by the Air Force Cambridge Research Laboratories, and the processing of flight data.
