Find sources: – ( June 2017) () Fermi includes two scientific instruments, the Large Area Telescope (LAT) and the Gamma-ray Burst Monitor (GBM). • The LAT is an imaging gamma-ray detector (a instrument) which detects with energy from about 20 million to about 300 billion (20 MeV to 300 GeV), with a field of view of about 20% of the sky; it may be thought of as a sequel to the instrument on the. • The GBM consists of 14 scintillation detectors (twelve crystals for the 8 keV to 1 MeV range and two crystals with sensitivity from 150 keV to 30 MeV), and can detect gamma-ray bursts in that energy range across the whole of the sky not occluded by the Earth. Fermi on Earth, solar arrays folded Advanced Information Systems (formerly Spectrum Astro and now ) in, designed and built the that carries the instruments. It travels in a low, circular orbit with a period of about 95 minutes.

In condensed matter physics, the Fermi surface is the surface in reciprocal space which separates occupied from unoccupied electron states at zero temperature. The shape of the Fermi surface is derived from the periodicity and symmetry of the crystalline lattice and from the.

Its normal mode of operation maintains its orientation so that the instruments will look away from the Earth, with a 'rocking' motion to equalize the coverage of the sky. The view of the instruments will sweep out across most of the sky about 16 times per day. The spacecraft can also maintain an orientation that points to a chosen target. Both science instruments underwent environmental testing, including vibration, vacuum, and high and low temperatures to ensure that they can withstand the stresses of launch and continue to operate in space. They were integrated with the spacecraft at the General Dynamics ASCENT facility in Gilbert, Arizona. Data from the instruments are available to the public through the Fermi Science Support Center web site.

Software for analyzing the data is also available. GLAST renamed Fermi Gamma-ray Space Telescope [ ] Fermi gained its new name in 2008: On 26 August 2008, GLAST was renamed the 'Fermi Gamma-ray Space Telescope' in honor of, a pioneer in high-energy physics. NASA's, associate administrator for Science at NASA Headquarters, launched a public competition 7 February 2008, closing 31 March 2008, to rename GLAST in a way that would 'capture the excitement of GLAST's mission and call attention to gamma-ray and high-energy astronomy. Something memorable to commemorate this spectacular new astronomy mission. A name that is catchy, easy to say and will help make the satellite and its mission a topic of dinner table and classroom discussion'. Anticipated first year of operations timeline NASA designed the mission with a five-year lifetime, with a goal of ten years of operations. The key scientific objectives of the Fermi mission have been described as: • To understand the mechanisms of particle acceleration in (AGN), pulsars, and (SNR).
