Granat was used to study both interstellar x rays and gamma rays. The instruments on board were developed by Russia and France. For the first few years of its nine years of service, the satellite made targeted observations. In 1994, Granat began operating in survey mode because its fuel supply was exhausted so the spacecraft could no longer aim. Besides its cosmic ray detections, a highlight of the mission is its deep imaging of the galactic center.
