Abstract
The Constellation-X mission is a large collecting area x-ray facility, emphasizing observations at high spectral resolution while covering a broad energy band. By increasing the telescope aperture and utilizing efficient spectrometers the mission will achieve a factor of 100 increased sensitivity over current high resolution x-ray spectroscopy missions. The use of focusing optics across the 10-40 keV band will provide a similar factor of 100 increased sensitivity in this band. Key technologies under development for the mission include lightweight high throughput x-ray optics, multilayer coatings to enhance the hard x-ray performance of x-ray optics, micro-calorimeter spectrometer arrays with 2 eV resolution, low power and low weight CCD arrays, lightweight gratings and hard x-ray detectors. When observations commence towards the end of the next decade, Constellation-X will address many pressing questions concerning the extremes of gravity and the evolution of the Universe.
