The Chandra X-ray Observatory is the world's most powerful X-ray telescope. Chandra is designed to observe X-rays from high-energy regions of the universe, such as the remnants of exploded stars. Along with the Hubble Space Telescope, the Spitzer Space Telescope, and the now de-orbited Compton Gamma Ray Observatory, Chandra is one of NASA's "Great Observatories."

The Smithsonian Astrophysical Observatory in Cambridge, Mass., is responsible for the day-to-day flight operations and science activities for Chandra from the Operations Control Center and Chandra X-ray Center facilities.
