A SpaceX Falcon 9 rocket rumbled into the sky Wednesday from NASA’s Kennedy Space Center in Florida, flexing the rocket’s muscles and lofting a massive Intelsat satellite to orbit supporting wireless communications, television broadcasting and trans-Atlantic data relays.

Boeing officials said Monday the company’s Starliner crew capsule will fly a second time without astronauts after software problems and other issues plagued a first test flight in December, preventing the ship from reaching the International Space Station.

The massive 212-foot-long core stage of the Space Launch System rocket arrived at NASA’s Kennedy Space Center late Tuesday morning. Rollout to the VAB is set to begin around 9 a.m. EDT on Wednesday.
