After a failed earlier attempt, an European cargo spacecraft has adjusted the orbit of the International Space Station (ISS) to create best conditions for the upcoming docking of Russia's manned spaceship Soyuz, the Russian Mission Control Center said Wednesday.

"The ATV-3 engines have worked as planned. Correction of the ISS orbit is over," the Mission Control Center said.

The orbit has been adjusted twice during the day, elevated by 7.7 km to the average of 420 km.

Last Wednesday, the European Space Agency's Automated Transfer Vehicle Three, ATV-3, failed to raise the ISS to the prescribed orbit due to its booster's early switch-off.

The adjustment of the orbit is needed for the landing and next docking of Russia's manned spaceship Soyuz.

The landing of the outbound Soyuz TMA-04M spaceship, with two astronauts on board, is scheduled for Sept. 17. The docking of the Soyuz TMA-06M spacecraft with the ISS is set for Oct. 15.

ISS orbit adjustments are conducted periodically before launches of the Russian spaceships, to compensate for the Earth's gravity and ensure successful dockings. The next correction of the ISS orbit has been scheduled for Sept. 12.
