Russia's space agency says an unmanned cargo ship has blasted off successfully on a mission to deliver supplies to the international space station.
The agency said the Progress M-08M spacecraft lifted off Wednesday from the Baikonur cosmodrome in Kazakhstan. It's scheduled to dock with the station Saturday.
The Progress is carrying more than 2.5 metric tons of food, water, oxygen, fuel and other supplies for the station. It will also deliver letters and presents from home for the crew of six.
The space outpost is manned by U.S. astronauts Douglas Wheelock, Shannon Walker and Scott Kelly and Russians Alexander Kaleri, Oleg Skripochka and Fyodor Yurchikhin.
