Photo of Fermi (IMAGE)
Caption
This photograph, taken in May 2008 as the Fermi Gamma-ray Space Telescope was being readied for launch, highlights the detectors of the spacecraft's Gamma-ray Burst Monitor (GBM). An identical set of detectors is mounted on the opposite side of the spacecraft. The GBM is an array of 14 crystal detectors designed for transient lower-energy gamma-ray outbursts, such as TGFs.
