Russia launches 4 more satellites

Russia has successfully launched four satellites into orbit, an Associated Press report said, quoting local media.

The ITAR-TASS news agency says a booster rocket, launched from a northern base, has placed three military satellites and one experimental one into a designated orbit.

The report says the experimental satellite will maneuver in space using a solar-powered engine. It does not discharge a jet to generate thrust and is moved by whirling fluid and solid elements inside.

The satellite will also broadcast a radio program and images describing the history of the Soviet space program. The broadcasts will commemorate the launch of Sputnik, the satellite that opened the space age in 1957. Russia has about 100 satellites in orbit.
