General Dynamics Advanced Information Systems has successfully completed the Launch and Early Orbit Phase (LEOP) of NASA’s Fermi Gamma-ray Space Telescope. Fermi, previously known as the Gamma-ray Large Area Space Telescope or GLAST, is a nexgen, high-energy, gamma-ray satellite designed to make observations of celestial gamma-ray sources. NASA recently renamed the satellite in honor of Prof. Enrico Fermi (1901 - 1954), a pioneer in high-energy physics. The LEOP is a functional checkout of the observatory which demonstrates that all the instruments and subsystems perform to meet Fermi’s mission. NASA Goddard Space Flight Center is now managing daily operations of the observatory. Fermi was launched on June 11, 2008. As system integrator for the GLAST observatory, General Dynamics was responsible for the design and manufacture of the spacecraft bus, integration of the government-furnished instruments, full system testing, supported launch processing, and on-orbit checkout. General Dynamics assembled the spacecraft and integrated the payload at its space-systems factory in Gilbert, Arizona.
