AGILE is an ASI (Italian Space Agency) space mission with scientific and programmatic participation by INAF, INFN and CIFS, devoted to gamma-ray astrophysics. AGILE is an Italian Research Infrastructure open to the international community. The satellite was launched on 23 April 2007 and is currently in its seventh year of successful operations in space. Its operative phase has been approved by ASI at least until the end of 2013, with the possibility of further extensions.The AGILE space mission is devoted to high-energy astrophysics for the study of the universe and the Earth. Its imaging detectors are sensitive in the energy range 30 MeV – 30 GeV for gamma-ray detection, and in the range 15-60 keV for hard X-ray detection. A non-imaging detector completes the instrument with excellent timing in the energy range 0.4-100 MeV. AGILE is an ASI “Small Scientific Mission” (the first of its class for Italy) with highly optimized resource management. Over the years, AGILE has produced important scientific results on many cosmic gamma-ray sources, both in our galaxy and in other distant galaxies. Among the most relevant results was the unexpected discovery of strong gamma-ray flares from the Crab Nebula. For this discovery the AGILE Principal Investigator, Marco Tavani, and the AGILE Team were awarded the prestigious 2012 "Bruno Rossi Prize" by the American Astronomical Society. The Mission is also making a crucial contribution to the study of the Earth's atmosphere by detecting very energetic terrestrial gamma-ray flashes (TGFs).All AGILE data (i.e. both from the AGILE Team reserved projects and from the Guest Observer Program) are publicly available to the international scientific community after a one-year proprietary period, through the AGILE Data Center (ADC) webpages (http://agile.asdc.asi.it/).
