CAPE CANAVERAL - NASA has set May 31 for the next space shuttle launch and said that Russia's investigation into last month's rocky landing of its own spacecraft shouldn't interfere.
Senior NASA managers agreed Monday to proceed as planned with Discovery's two-week trip to deliver a Japanese lab to the International Space Station. A Russian Soyuz ship is always docked there as an emergency "lifeboat" in case the crew needs it.
The most recent Soyuz that flew made an off-course, steeper-than-usual descent on April 19. One of the three astronauts returning in it ended up in the hospital with back pain. The Russian Space Agency is investigating what went wrong.
Bill Gerstenmaier, NASA's space operations chief, said the Russians hope to wrap up the probe by the end of the month. Even if it's not complete before Discovery launches, officials think the Soyuz at the space station is reliable in case of an emergency.
NASA astronaut Gregory Chamitoff is flying up on Discovery and is supposed to remain at the space station for six months. He will replace another American, Garrett Reisman, who was dropped off in March.
Gerstenmaier said there would be no benefit to delaying the shuttle mission to allow the Russians more time to figure out what went wrong with their Soyuz. It was the second flawed landing in a row for a Soyuz spacecraft.
Just in case, NASA has looked at what it would take to bring eight astronauts back in the shuttle instead of seven - Chamitoff being No. 8 - and would be prepared to do so, Gerstenmaier said. However, he stressed that would be extremely unlikely.
Estimated odds are 1 in 124 that a Soyuz would be needed.
