The spacecraft will c arry a scientific payload integrated by two co-ordinated solar experim ents to observe solar flares; an instrument to measure the X-ray time profile of gamma-ray bursts and a spectrometer for the measurement of the cosmic diffuse X-ray background. The SAC-B mission will use a low- cost, small spacecraft which is being designed and will be constructed in Argentina. The SAC-B is planned to be launched, using a NASA-provi ded PEGASUS rocket, in December of 1994.
