One of the scientific goals of the main instrument of l GLAST is the study of gamma-ray bursts (GRBs) in the energy range from ∼20 MeV to ∼300 GeV. In order to extend the energy measurement towards lower energies, a secondary instrument, the l GLAST Burst Monitor (GBM), will measure GRBs from ∼10 keV to ∼25 MeV and will therefore allow the investigation of the relation between the keV and the MeV--GeV emission from GRBs over six energy decades. These unprecedented measurements will permit the exploration of the unknown aspects of the high-energy burst emission and the investigation of their connection with the well-studied low-energy emission. They will also provide new insights into the physics of GRBs in general. In addition, the excellent localization of GRBs by the Large-Area Telescope will stimulate follow-up observations at other wavelengths which may yield clues about the nature of the burst sources.
