The rupee is the currency of the Seychelles. It is subdivided into 100 cents. In the local Seychellois Creole (Seselwa) language, it is called the roupi. The international currency code is SCR. The abbreviations SR and SRe are sometimes used. Several other currencies are also called rupee.

British Colony

The British Legislative Council authorized the establishment of a Board of Commissioners of Currency through the Paper Currency Ordinance of 1914, which was enacted by C. R. M. O’Brien, the governor of the Colony of the Seychelles on 10 August 1914. In 1914, the government produced emergency issues of notes for 50 cents, 1, 5 and 10 rupees.

Standard issue notes began to be issued in 1918, with notes for 50 cents and 1 rupee, followed by 5, 10 and 50 rupees in 1928. The 50 cents and 1 rupee notes were issued until 1951 and phased out in favor of the coins. 20- and 100-rupee notes were first introduced in 1968, whilst the 5-rupee note was replaced by a coin in 1972.

The Space Capsule Recovery Experiment (SCRE or more commonly SRE or SRE-1) is an Indian experimental spacecraft which was launched at 03:53 GMT on January 10, 2007 from Sriharikota by the Indian Space Research Organisation (ISRO). The launch was conducted using the PSLV C7 rocket, along with three other satellites. 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 GMT on January 22.

Overview

SRE-1 was designed to demonstrate the capability to recover an orbiting space capsule, and the technology of an orbiting platform for performing experiments in microgravity conditions. It was also intended to test reusable Thermal Protection System, navigation, guidance and control, hypersonic aero-thermodynamics, management of communication blackout, deceleration and flotation system and recovery operations.

Design

SRE-1 is a 555 kg capsule. 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. It also houses two microgravity payloads. It has a sphere-cone-flare configuration with a spherical nose of about 0.5 m radius, base diameter of 2 m and 1.6 m height. 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-1 capsule. Parachutes for SRE capsule were provided by ADRDE.
