text:  Elsewhere, NASA says two astronauts will stay in space a little bit longer this week to continue troubleshooting Boeing's capsule. Butch Wilmore and Sonny Williams arrived on Boeing's new space capsule about a month ago. I want to make it very clear that Butch and Sonny are not stranded in space. This was the first astronaut launch for Boeing after years of delays and setbacks. NASA's Steve Stitch says engineers are troubleshooting some problems. We'll have a little bit more work to do to get there for the final return.
