Live coverage: Soyuz sends Russian and two Americans to space station

Crew members on the International Space Station over the weekend continued trying to pinpoint the location of a small air leak in the research outpost’s Russian Zvezda service module, one of the oldest sections of the orbiting laboratory.

The launch of a Japanese H-2B rocket was called off Tuesday after a fire broke out on the launch pad a few hours before liftoff. A new target launch date has not been confirmed. The mission will carry an HTV cargo ship into orbit on a resupply run to the International Space Station.
