MTI (Multispectral Thermal Imager) is a satellite sponsored by the US Department of Energy, Office of Nonproliferation and National Security, to demonstrate advanced multispectral and thermal imaging, image processing, and associated technologies that could be used in future systems for detecting facilities that produce weapons of mass destruction. MTI carries a sophisticated telescope to collect day and night images of Earth in 15 spectral bands ranging from the visible to long-wave infrared. It also carries a High-energy X-ray Spectrometer (HXRS) sponsored by NOAA (National Oceanic and Atmospheric Administration) and the Czech Republic's Astronomical Institute of the Academy of Sciences. As a side benefit, HXRS gathers data needed to better understand powerful solar flares that can endanger astronauts and damage space equipment.
