A Russian cargo spacecraft carrying food and supplies blasted off Saturday for the international space station, mission control said.

The spacecraft, which is scheduled to dock at the orbiting space station on Monday, is transporting almost 3 tons of fuel, food and water, along with equipment.
　　
Russian cosmonaut Pavel Vinogradov and U.S. astronaut Jeffrey Williams began a six-month mission on the station April 1.
