Instruments
Large Area Telescope (LAT)
The LAT is an imaging high-energy gamma-ray telescope covering the energy
range from about 20 MeV to more than 300 GeV.
GLAST Burst Monitor (GBM)
The GBM complements the LAT in its observations of transient sources and is
sensitive to X-rays and gamma rays with energies between 8 keV and 40 MeV.
Objectives of the Fermi Mission
• Explore the most extreme environments in the universe, where nature
harnesses energies far beyond anything possible on Earth
• Search for signs of new laws of physics and what composes the mysterious
dark matter
• Explain how black holes accelerate immense jets of material to nearly light
speed
• Help crack the mysteries of the stupendously powerful explosions known as
gamma-ray bursts
• Answer long-standing questions across a broad range of topics, including
solar flares, pulsars and the origin of cosmic rays
