Summary
COSMOS 2427 (also known as Kosmos-2427) is a reconnaissance satellite launched by Russia on June 7, 2007, from the Plesetsk Cosmodrome LC16/2 using a Soyuz-U-PVB launch vehicle. The spacecraft, based on the Yantar'-4K2M bus, measures 6.3 meters in length and has a diameter of 2.7 meters with a span of 6.3 meters. It weighs 3186 kilograms both at launch and as its dry mass. The satellite's mission is reconnaissance through photography using film return technology, equipped with two small reentry capsules and deployable solar arrays for power generation. Manufactured by ARSL (Arsenal) under the ownership of KVR (Central Research Institute of Machine Building), COSMOS 2427 was operational for a reported lifetime of 130 days.

The Satellite That Found 22 Photons and Changed Astronomy
On April 27, 1961, a Scout rocket lifted a 37-kilogram NASA satellite into orbit from Wallops Island carrying the first serious instrument for detecting cosmic gamma rays. Explorer 11 operated for seven months before its tape recorder failed. In that time it registered 22 gamma-ray photons - a pitiful number by modern standards, but enough to launch an entire branch of astronomy.
