Space Station Crew Closely Watching Russian Rocket Crash Investigation

The Soyuz rocket was carrying Russia's Progress 44 supply ship for the International Space Station, which was expected to deliver 3 tons of supplies to the orbiting lab's six-man crew. Instead, the rocket and cargo ship crashed in eastern Russia after a malfunction in the booster's third stage forced an engine shutdown.

"It's a pity the launch of Progress resupply vehicle didn't go well. Experts have worked on the investigation of its various impacts," station astronaut Satoshi Furukawa of Japan wrote on Aug. 26, two days after the crash, on Twitter, where he posts updates about his mission as @Astro_Satoshi. "But, as there are plenty of supplies to support the crew, we'll be fine for a while."

Since Russia's Federal Space Agency uses similar versions of its Soyuz rocket design to launch unmanned Progress vehicles and its crewed space capsules, officials want to make sure that they are safe to carry astronauts and cosmonauts. The next Soyuz to ferry a crew to the station was slated to launch Sept. 22 to replace three astronauts who are due to return home on Sept. 8.

Those plans may now change, the astronauts said. It's possible that the launch of the new station crew will be delayed until the crash investigation is complete, and that may force the three returning crewmembers to stay in orbit longer than planned.
