Russia's space agency says an unmanned cargo ship carrying 2.6 tons of supplies and equipment has lifted off for the International Space Station.
Roskosmos says the Progress M-14M blasted off early Thursday from the Baikonur cosmodrome in Kazakhstan atop a Soyuz-U booster rocket.
The ship is scheduled to dock at the space station early Saturday with a cargo of oxygen, food, scientific equipment and gifts for the crew.
The space station's six members include three Russians, two Americans and a Dutchman.
The decade-old station is orbiting about 225 miles (360 kilometers) above Earth and consists of 13 modules.
