Live coverage: Veteran three-man crew docks with space station

Engineers are troubleshooting a small air leak aboard the International Space Station that was discovered last September, NASA reported Thursday. While it poses no safety threat, the lab’s three-man crew plans to seal themselves in the Russian segment of the station this weekend to help engineers pin down the leak’s location.

Japan’s HTV supply ship fell to Earth on Sunday more than a week after leaving the International Space Station, burning up in the atmosphere after officials gave up on an experiment looking into ways to remove space junk from orbit.

A logistics-delivery vessel for the International Space Station, launched and operated privately by commercial companies on behalf of NASA, is scheduled to arrive at the lab complex Saturday at 6:05 a.m. EDT (1005 GMT).
