What time will SpaceX launch NASA's Roman Space Telscope on Aug. 30? (Full mission timeline)

A huge SpaceX rocket is just days away from launching NASA's next great observatory into space: the Roman Space Telescope. But if you're hoping to watch it live online, you'll have to get up pretty early on Sunday (Aug. 30) or you'll miss it. NASA's Roman Space Telescope, named after the late NASA astronomer Nancy Grace Roman, will launch no earlier than Sunday on a mission to map the galaxy like never before. Liftoff is set for 7:26 a.m. EDT (1126 GMT) from a NASA pad in Cape Canaveral, Florida
