Elon Musk and Donald Trump have made plenty of hay around Suni Williams and Butch Wilmore, two astronauts that have been stuck on the International Space Station since last June. Just a month into the Trump administration, Musk has found that successfully swapping ISS crews on time is easier said than done.
A joint launch between Musk-led SpaceX and NASA was set to send a crew to the orbiting station and begin the process of sending the waiting Wilmore and Williams back to Earth. However, that Wednesday launch was scrubbed when Cape Canaveral crews detected a problem with a clamp that helps to hold the Falcon 9 rocket upright on the launchpad. The postponed launch could be rescheduled as soon as Thursday, provided the issue is addressed.
