Space Station Orbit Readjusted for Progress Docking

RIA Novosti

15:59 29/02/2012 MOSCOW, February 29 (RIA Novosti) - Russian Mission Control specialists on Wednesday readjusted the orbit of the International Space Station (ISS) by 2.1 kilometers to ensure the best conditions for the docking of Russia’s Progress M-15M cargo spacecraft.

The main engines of the Russian Zvezda Service Module were turned on for about one minute to conduct the readjustment.

“As a result, the ISS received an additional impulse of 1.2 meters per second. The average orbital altitude of the station increased by 2.1 kilometers and is now at 391.3 kilometers,” a spokeswoman for the ISS said.

The launch of the Progress M-15M spaceship from the Baikonur Space Center in Kazakhstan is scheduled for April 20.

Corrections to the space station's orbit are conducted periodically before spacecraft launches to compensate for the Earth's gravity and to safeguard successful dockings and landings.
