It remained in orbit for 12 days before re-entering the Earth's atmosphere and splashing down into the Bay of Bengal at 04:16 UTC on January 22.

It comprises aero-thermo structure, internal structure, Mission Management Unit, Altitude sensors and Inertial measurement unit, S-band transponder with unique belt array antenna embedded to ATS, power and electronics packages to support deceleration and flotation system.

Parachutes for SRE capsule were provided by Aerial Delivery Research and Development Establishment (ADRDE).

[10] To withstand the heat of re-entry, the cone-shaped SRE-1 has a thermal protection system composed of 264 silica tiles of 14 different types over conical surface,[11] and an ablative nose cap of carbon-phenolic composite.

Scaled replica of SRE with this thermal protection system was validated in Plasma Wind Tunnel facility of CIRA, Italy.

During its reentry, the capsule was protected from the intense heat by carbon phenolic ablative material and silica tiles on its outer surface.
