Watch live: NASA’s new moon rocket rolls to launch pad tonight

NASA will roll the Space Launch System, a heavy-duty rocket designed to send astronauts to the moon, out of the iconic Vehicle Assembly Building at the Kennedy Space Center on Thursday evening. A crawler-transporter originally built more than 50 years ago for the Apollo program will haul the towering rocket to its launch pad for a countdown dress rehearsal. The rollout is set to begin at 5 p.m. EDT (2100 GMT).
