The Alkali Metal Thermal-To-Electric Converter for Solar System Exploration

AMTEC, the Alkali Metal Thermal to Electric Converter, is a direct thermal to electric energy conversion device; it has been demostrated to perform at high power densities, with open circuit voltages in single electrochemical cells up to 1.6 V and current desities up to 2.0 A/cm(sup 2).

High Resolution UV Spectroscopy for Solar System Exploration

A new generation of high resolution UV imaging spacecraft (Polar, Galileo, HST) are studying the airglow and aurora of the Earth and the jovian planets. To keep pace with these technological improvements we have developed a laboratory program to provide electron collision cross sections of the major molecular planetary gasses. Molecular spectra under optically thin conditions have been measured with a high resolution UV spectrometer in tandem with an electron impact collision chamber. The results of various studies are reported in this paper.

Miniature Low Power Submillimeter-Wave Spectrometer for Detection of Water in the Solar System

The mass and power of a heterodyne spectrometer must be greatly reduced to satisfy small space mission constraints. We report on a 220 GHz receiver, requiring less than 4.8 W, with a mass of 1.25 kg. The mass and power savings are achieved through reducing components to a minimum, while providing performance for a Martian atmospheric sounder.

IUE Views the Solar System

The ultraviolet spectral region is important to the entire community of astronomers from those who study nearby objects such as the earth's moon to those who study objects at the edge of the observable universe.
