MOSCOW, July 10 (Itar-Tass) - RKA Mission Control Center will correct the orbit of the International Space Station for the docking of a Progress M-20M cargo ship that is expected to be launched from the Baikonur cosmodrome later this month.
Engines of Europe’s robotic ATV-4 known as Albert Einstein will be used to raise the orbit. They will be switched on at 09:35 Moscow time for 593 seconds to give the ISS an additional boost of 1.45 meters per second. For this time the orbit will be raised by approximately 2.5 kilometers and the orbit’s average altitude will reach 417.3 kilometers.
Earth gravity and other factors reduce an orbital altitude by 150-200 meters per day.
