As part of the mission, ISRO's workhorse Polar Satellite Launch Vehicle (PSLV-C7) had put Space Capsule Recovery Experiment satellite into space alongwith three others on January 10, space agency sources said. The capsule splased down around 9.30 am, ISRO sources told PTI, adding that efforts were being made to recover it. "The capsule has splashed down. The Coast Guard has located the area," they said. The 550-kg SRE, which would help ISRO hone its skills in re-entry, recoverable and re-usable technologies, had two payloads to conduct experiments in micro-gravity. SLV-C7 had injected India's Cartosat-2, apart from SRE satellite, and two others from overseas -- LAPAN-TUBSAT, a joint venture of Indonesia and the Technical University of Berlin, and the Pehuensat-1 of Argentina. The 550-kg Space-Capsule Recovery Experiment was intended for demonstrating the capability to recover an orbiting space capsule, as also the associated technologies. "SRE is intended to test reusable thermal protection system, navigation, guidance and control, hypersonic aero-dynamics, management of communication blackout, deceleration and floatation system and recovery experiments," ISRO officials said. SRE, according to ISRO, is made of mild-steel, and comprises aero-thermo structure, spacecraft platform, deceleration and floatation system and micro-gravity payloads. The parachute, pyro devices, avionics packages of triggering unit and sequencer, telemetry and tracking system and sensors for measurement of system performance parameters are placed inside the SRE capsule. Congrats to ISRO SCIENTISTS!!!!!
