Lost Russian satellite found in wrong orbit
A Russian telecommunications satellite that was launched on Thursday disappeared from the view of ground controllers and the U.S. space surveillance network, along with the rocket upper stage that carried it into orbit, according to industry officials and the Russian space agency, Roscosmos. After the 5,800-kilogram Express-AM4 satellite separated from the Proton rocket’s Breeze-M upper stage, neither object could be found, officials said. The U.S. Space Surveillance Network of ground radars was tracking a single object that one official said was neither the Breeze-M nor the Express-AM4, but rather an auxiliary propellant tank from the Proton rocket.
But by midday ET on Friday, the U.S. Space Surveillance Network had located the Express-AM4 satellite, saying it was in an orbit with an apogee of 20,317 kilometers, a perigee of 1,007 kilometers and an inclination relative to the equator of 51.3 degrees. One industry official said it would be difficult, from this position, to maneuver Express-AM4 into operational position in geostationary orbit with sufficient life remaining to make the effort worthwhile.
