The engines of a Russian Progress spacecraft were used Tuesday to boost the International Space Station's altitude. The unpiloted vehicle, which docked with the station Feb. 4 hauling supplies for the Expedition Six crew, also carried additional fuel to raise the station's orbit.

Beginning at 5:34 a.m. CST (1134 GMT), its engines were fired for 22 minutes, increasing the station's altitude from 394 by 376 kilometers (213 by 203 nautical miles) to 406 by 385 kilometers (219 by 208 nautical miles).
The station is now in the correct altitude for a Soyuz taxi flight, which is scheduled to arrive at the station in late April.
