In April 2009 Russian news media reported that a 'perpetual motion' space engine had been tested on spacecraft: "Specialists of the Institute for Space Systems conducted successful tests of the perpetual motion machine in space," wrote 'Pravda' in Moscow. "Valery Menshikov, the director of the institute, said that the machine was installed at Yubileiny satellite which was launched into orbit almost a year ago. The satellite can now move from one orbit to another with the help of the engine, which discharges no reaction mass."

Menshikov continued, in a claim not verified by any Western space source: "The first tests were conducted in June and July of 2008. The tests revealed some problems that need further developments of the machine, but the orbital experiment was conducted successfully in general."
