The Cosmic Radiation Satellite, CORSA, had the shape of an octagonal right prism with a maximum size of 80 cm and a height of 65 cm. The spacecraft was spin stabilized and capable of being pointed toward any interesting object in the sky. Three kinds of x-ray detectors were to look parallel and perpendicular to the spin axis of the satellite. With these detectors, x-ray sources could be observed over a wide-band energy range and a short time resolution. A core memory of 4000 words would have stored the data during the time when the satellite was not in contact with a telemetry station. The CORSA satellite was launched on February 6, 1976, but failed to achieve orbit.
