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.

The delayed mission must reach the space station before the two astronauts who've been "stuck" in space can return home.

Depending on weather and clouds, rocket launches from Kennedy Space Center or Cape Canaveral can be seen from Daytona Beach to Melbourne to Vero Beach
