NASA's two stuck astronauts may end up back on Earth a little sooner than planned. The space agency said Tuesday that SpaceX will switch capsules for upcoming crew flights to bring Butch Wilmore and Suni Williams home in mid-March instead of late March or April.

NASA on Tuesday swapped out the astronaut capsule it plans to use for an upcoming routine flight to the International Space Station over SpaceX production delays, a scheduling move that allows for a slightly earlier return for the two astronauts who have been on the station far longer than expected.
