Russian cargo ship heads to space station

An unmanned Russian space cargo ship blasted off this morning, carrying food and other supplies for the International Space Station.

The Progress 47 supply shiplaunched at8:50 a.m. ET on a Soyuz rocket from the Baikonur Cosmodrome in Kazahkstan, NASA confirmed half an hour before liftoff.

The spaceship is filled with 2.5 tonnes of food, fuel and other supplies. It is scheduled to arrive at the space station on April 22.

This is the third Progress launch since a failed onelast August that was later blamed on a manufacturing flawin the Soyuz rocket. Subsequent launches in October and January were both successful.

Russia has been sending Progress spacecraft up to its ownspace stations since the 1980sand began sending them to the International Space Station in 2000. However, reliance of the space station on unmanned cargo ships, including Progress, has increased since NASA retired its space shuttle fleet last year.
