SROSS 3 was an Indian remote sensing spacecraft launched by an ASLV booster from the Sriharikota Center in India. This Stretche Rohini Satellite Series spacecraft provided India with its first astrophysics observatory, albeit temporarily. The primary purpose of the flight was to test the ASLV launch vehicle which had failed on the two previous attempts. The SROSS 3 was a payload of opportunity which carried a geophysics package and a gamma ray burst detector. The latter was tuned to the energy range of 20 keV-3 MeV and consisted of high voltage scintillation detectors. The observational program was concentrated on the southern celestial sky. Unfortunately, the 106-kg spacecraft decayed after only 55 days instead of an anticipated one year due to the less-than-nominal performance of the launch vehicle.
