Active Missions AGILE - first and unique combination of a gamma-ray and an hard X-ray imager. (2007 - present) Chandra - 64-hour highly-eccentric Earth orbit with unprecedented x-ray imaging. (1999 - present) Fermi Gamma-ray Space Telescope (formerly GLAST) - studies the cosmos in the 30 MeV to 10 GeV range with unprecedented sensitivity and spatial resolution. (2008 - present) INTEGRAL - International Gamma-Ray Astrophysics Laboratory. High spectral and spatial resolution. (2002 - present) RXTE - Rossi X-ray Timing Explorer. Very large collecting area and all-sky monitoring of bright sources combined with good timing. (1995 - present) Suzaku - First satellite to carry a new type of X-ray spectrometer, the X-ray micro-calorimeter. Broad energy range. (2005 - present) Swift - Autonomous spacecraft response to GRB. Accurate position estimates within minutes. Multiwavelength observations. (2004 - present) XMM-Newton - Very large collecting area. Simulataneous X-ray & Optical observations. (1999 - present)
