Space Capsule Recovery Experiment (SRE – 1) is a 550 kg
capsule intended to demonstrate the technology of an orbiting platform for
performing experiments in micro gravity conditions. After completion of the
experiments, the capsule was de-orbited and recovered. SRE – 1
mission provided a valuable experience in fields like navigation, guidance
and control during the re-entry phase, hypersonic aero thermodynamic,
development of reusable thermal protection system (TPS), recovery through
deceleration and flotation, besides acquisition of basic technology for
reusable launch vehicles.
SRE – 1 carries two experiments, an Isothermal Heating Furnace (IHF) and a
Bio-mimeic experiment. SRE was launched into a 635 km polar SSO in January 2007
as a co-passenger with CARTOSAT -2 and stayed in orbit for 10 days during which
its payloads performed the operations they are intended to. The SRE capsule was
de-boosted and recovered successfully back on earth on 22nd January 2007.
