Craft's Space Station docking fails

An unmanned Russian cargo spacecraft has failed to dock with the International Space Station due to a technical failure, officials said.

Russian Mission Control said the spacecraft will make another attempt at docking on Sunday.

The Progress cargo ship separated from the station last Sunday to perform engineering tests and try out a new docking system.

There are currently six people on the Space Station - three Russians, two Americans and a Japanese astronaut.

Russia's Mission Control did not name the specific cause of the failure, but said they are looking into it.
