Watch live: SpaceX Crew-10 launch to ISS

Four astronauts preparing for a routine mission that sets the stage for the Boeing Starliner crew to depart from the International Space Station could potentially get off the ground Friday night from Florida. A mission known as Crew-10, jointly operated by NASA and SpaceX, was called off Wednesday night less than an hour before it was due to launch. The delay, prompted by an issue with the launchpad’s ground system, further hindered the return of the two NASA astronauts who in June flew to the space station aboard the troubled Starliner. Butch Wilmore and Suni Williams have for more than nine months anticipated the arrival of the Crew-10 team, who will replace the outgoing Crew-9 astronauts for a routine stint doing science and maintenance at the orbital laboratory.
