The space agency announced Tuesday that SpaceX will switch capsules for upcoming astronaut flights in order to bring Butch Wilmore and Suni Williams home in mid-March instead of late March or April. That will shave at least a couple weeks off their prolonged stay at the International Space Station, which hit the eight-month mark last week.
