摘要
The Constellation-X Observatory is currently planned as NASA's next major X-ray observatory to be launched towards the end of the next decade. The driving science goals for the mission are to: 1) Trace the evolution of Black Holes with cosmic time and determine their contribution to the energy output of the Universe; 2) Observe matter spiraling into Black Holes to test the predictions of General Relativity; 3) Use galaxy clusters to trace the locations of Dark Matter and follow the formation of structure as a function of distance; 4) Search for the missing baryonic matter; 5) Directly observe the dynamics of Cosmic Feedback to test models for galaxy formation; 6) Observe the creation and dispersion of the elements in supemovae; and 7) Precisely constrain the equation of state of neutron stars. To achieve these science goals requires high resolution (R > 1250) X-ray spectroscopy with 100 times the throughput of the Chandra and XMM-Newton. The Constellation-X Observatory will achieve this requirement with a combination of four large X-ray telescopes on a single satellite operating in the 0.25 to 10 keV range. These telescopes will feed X-ray micro-calorimeter arrays and grating spectrometers. A hard X-ray telescope system will provide coverage up to at least 40 keV. We describe the mission science drivers and the mission implementation approach.
