Photos: Delta 4’s foggy launch

The towering structure to be used for liftoffs of NASA’s Space Launch System rolled from a construction site to launch pad 39B at the Kennedy Space Center in Florida this week, arriving at the seaside complex Friday for a week of fit checks.

SpaceX is set to resume launches from pad 40 at Cape Canaveral in December with the liftoff of a space station-bound supply ship on top of a Falcon 9 booster, a major step in boosting the company’s flight rate and readying for the debut of the long-delayed Falcon Heavy rocket.
