UK-DMC 2 is a British Earth imaging satellite which is operated by DMC International Imaging.[5] It was constructed by Surrey Satellite Technology, based on the SSTL-100 satellite bus.[1][5] It is part of Britain's contribution to the Disaster Monitoring Constellation, which is coordinated by DMC International Imaging. It is the successor to the UK-DMC satellite.


UK DMC-2 was launched into a sun-synchronous low Earth orbit. The launch was conducted by ISC Kosmotras, using a Dnepr carrier rocket, with DubaiSat-1 being the primary payload. UK-DMC 2, along with the Deimos-1, Nanosat 1B, AprizeSat-3 and AprizeSat-4 satellites, were the rocket's secondary payload. The launch occurred at 18:46 GMT on 29 July 2009, with the rocket lifting off from Site 109/95 at the Baikonur Cosmodrome in Kazakhstan.

The satellite has a mass of 120 kilograms (260 lb)[1] and a design life of five years. It carries a multi-spectral imager with a resolution of 22 metres (72 ft) and 660 kilometres (410 mi) of swath,[6] operating in green, red and near infrared spectra.

The satellite is also known as Blue Peter 1, and its construction and launch were followed by children's television.[7]
