SROSS (Stretched Rohini Satellite Series)
 |
SROSS B
|
Spacecraft developed by the Indian Space Research
Organisation (ISRO) as follow-ons to the successful Rohini
satellite series. SROSS satellites, which measured 1.1 × 0.8 m, were
designed to carry small scientific and technology payloads, including astrophysics,
remote sensing, and upper atmospheric monitoring experiments. They were
launched aboard developmental flights of India's new ASLV
(Advanced Space Launch Vehicle) from Sriharikota.
Both SROSS 1 and SROSS 2 were lost due to launch failures. The third vehicle,
SROSS C, was successfully placed in orbit, but one much lower than planned.
The vehicle decayed on Jul. 14, 1992, and although it returned some scientific
data was deemed only partially successful. SROSS C2 was the first unqualified
success of the SROSS and ASLV programs. SROSS C and C2 carried a gamma-ray
burst (GRB) experiment that monitored celestial gamma-ray bursts in the
energy range 20-3,000 keV, and a Retarded Potential Analyzer (RPA) experiment
that measured temperature, density, and characteristics of electrons in
the ionosphere.
