(FGST, GLAST, Fermi Gamma-ray Space Telescope, Gamma-ray Large Area Space Telescope)
(satellite for studying gamma rays)
Fermi (i.e., the Fermi Gamma-ray Space Telescope or FGST,
formerly the Gamma-ray Large Area Space Telescope or GLAST)
is a NASA space telescope for observing gamma rays.
Fermi was launched in 2008, is still operational as of June 2026,
and has the potential to continue operating for another decade or more.
USA budgeting efforts propose to eliminate funding of its operation
in 2027 even if it is still operational.
