The flight was scrubbed on Wednesday night, and the astronauts will return to the launchpad for their trip to the International Space Station.

NASA and SpaceX on Friday will count down to a long-awaited crewed rocket launch that will allow them to bring home U.S. astronauts Butch Wilmore and Suni Williams, who have been stuck on the International Space Station for nine months.

NASA and SpaceX successfully launched their SPHEREx and PUNCH missions into orbit Tuesday night from Vandenberg Space Force Base in California, to "collect" data on the sun and millions of galaxies.
