A power related fault which occured on 29 March has ended operations of the Canadian Spce Agency’s Radarsat 1. Unless engineers can recover the craft, the spacecraft will be retired due to failure. The spacecraft had exceeded its five year design life by over 12 years. A second radarsat spacecraft, Radarsat 2, remains in operation in orbit having been launched in 2007. Both Radarsats were designed to take Synthetic Aperture Radar (SAR) imagery of the Earth.
