The successful launch of the Fermi Gamma-ray Space Telescope marked a significant milestone in astronomical research. Lifted into orbit on a Delta II rocket from Cape Canaveral Air Force Station in Florida, Fermi is equipped with advanced instruments designed for sensitive detection of gamma-ray emissions from cosmic sources. The telescope's name honors the physicist Enrico Fermi, who made crucial contributions to the understanding of cosmic radiation and particles.

Fermi's mission is to observe gamma rays, a form of high-energy radiation resulting from some of the hottest and most violent phenomena in the universe. These include supernova explosions, the regions surrounding black holes, and active galactic nuclei. By monitoring gamma rays, Fermi helps to unlock mysteries about the origins and makeup of cosmic rays and the phenomena associated with dark matter. It also plays a key role in improving our understanding of fundamental particle physics and high-energy astrophysics.

Post-launch operations involved placing the telescope into its correct orbit and conducting in-orbit commissioning to ensure the instruments were functioning as designed. Once operational, Fermi began sending back data that scientists analyze to comprehend better the complexities of the universe. The mission's long duration aims to observe transient gamma-ray events across various astrophysical contexts and contribute significantly to multi-wavelength astronomy.
