Miniature Integrated Camera Spectrometer (MICAS)

NSSDCA ID: 1998-061A-01

Mission Name: Deep Space 1
Principal Investigator:Dr. Lawrence A. Soderblom


This experiment consists of two visible imaging channels, an ultraviolet imaging spectrometer, and an infrared imaging spectrometer, designed to return imaging data both for scientific purposes and also for use by the autonomous navigation test. The experiment itself will also serve as a test of the lightweight imaging technology. MICAS is mounted in a box-shaped compartment on one of the eight sides of DS1, away from the two solar panels. It is protected on top by a sun shade.

The two visible detectors operate between wavelengths of 500 and 1000 nm. One detector consists of a 1024 x 1024 CCD at 13 microrad per pixel. The other is a 256 x 256 CMOS active pixel sensor at 18 microrad/pixel. The ultraviolet spectrometer covers wavelengths from 80 to 185 nm with a spectral resolution of 2.1 nm at 316 microrad/pixel. The infrared spectrometer covers 1200 to 2400 nm with a spectral resolution of 12 nm at 53 microrad/pixel. Both spectrometers operate in puchbroom fashion. All four sensors share a single 10 cm diameter telescope. The sensors are directed by spacecraft pointing, there are no moving parts.
