Abstract

This paper will describe the miniaturization of the Thermal Emission Spectrometer (TES) electronic system for use in the Miniature-TES (Mini-TES) being built for Arizona State University. Mini-TES will be used to measure thermal emission for mapping of surface minerals on Mars. Mini-TES is a single pixel, Fourier Transform Spectrometer, covering 5 - 28 micrometer at 10 cm^-1 resolution. The Mini-TES electronics incorporate modern Field Programmable Gate Array (FPGA) technology, surface mount designs, and simplified command, control and data protocol allowing for a 4 fold reduction in the electronics subsystem. Use of the Lander computer for shared signal processing further help to reduce the Mini-TES complexity. Details of the specific flight hardware design, actual hardware fabrication and initial test results will be discussed.
