Video: Orion flight preps

Construction crews at NASA’s Kennedy Space Center are making steady progress outfitting the Space Launch System’s mobile platform with umbilical connections and access arms, and the walkway for astronauts to board the rocket is the most recent arrival at the Florida spaceport.

The pressurized crew module and European-built service module for NASA’s first Orion spacecraft to travel to the moon will be joined together for the first time in the coming weeks at the Kennedy Space Center, with preparations — at least for Orion — on a pace to be ready for launch on an unpiloted test flight next year.

Fueled segments of the solid rocket boosters that will lift off on the first flight of NASA’s Space Launch System have arrived at the Kennedy Space Center in Florida, but officials will hold off on stacking the boosters until the SLS core stage completes a crucial test-firing later this year.
