He said the correction was made without the participation of the space station's crew.

The ISS's orbit has been adjusted for the upcoming arrival of the U.S. shuttle Endeavor, whose launch date is scheduled for March 11, to compensate for the Earth's gravity and ensure a successful docking.

The space station's orbit was last corrected in January, when the station was raised 5.25 kilometers (3.26 miles) to an altitude of around 340 kilometers (about 211 miles) over the Earth's surface.
