This week, Space Shuttle mission STS-93 deployed the Chandra X-Ray Observatory, the world's most powerful X-Ray telescope. The third of NASA's "Great Observatories," the Chandra X-Ray Observatory will study X-Rays rather than visible light (the Hubble Space Telescope) or gamma rays (the Compton Gamma Ray Observatory). This site offers overviews and news of the Observatory and its mission. This resource is the official site of the STS-93 mission. The site offers mission synopses, breaking news, an overview of its primary payload -- the Chandra Observatory (with videos) -- and a collection of related links.
