Onward! Here's the view from the @ULALaunch Centaur upper stage as the @BoeingSpace #Starliner began flying on its own, bound for the @Space_Station. https://t.co/HNBMTCX3ut

LIVE: Join us for a post-launch briefing on #Starliner with leads from NASA, @BoeingSpace, and @ULALaunch: https://t.co/o5pwNwJYG3

RT @BoeingSpace: On its trip to @Space_Station, #Starliner has completed a phasing burn to achieve the nominal catch-up rate with ISS, and the spacecraft's entry cover has opened to prepare for docking.

A new @Commercial_Crew spacecraft is safely in orbit, and expected to arrive at the @Space_Station in less than 24 hours.

Get a recap of today's launch of the @BoeingSpace #Starliner aboard a @ULALaunch rocket, and details on how to watch docking: https://t.co/EvfKtyl1De https://t.co/DgJhjm3Bz9

RT @ulalaunch: We've had a successful staging on the #AtlasV. Separation of the first stage and ignition of the Dual Engine Centaur upper stage has occurred  off the coast of the Carolinas. Both engines are up and running. Live coverage available here: https://t.co/VIynIdVS23

RT @ulalaunch: #Starliner is riding 1.6 million pounds of thrust from #AtlasV to take aim on the @Space_Station for docking in 24 hours. Houston has assumed control as the rocket rolls to a northeasterly heading in pursuit of ISS, currently 262 miles above the North Atlantic approaching Europe.

3... 2... 1... Liftoff! #Starliner is headed to space, powered by @ULALaunch's Atlas V rocket.

This @BoeingSpace demo flight aims to certify a new spacecraft to transport astronauts to the @Space_Station. https://t.co/fORr5fRtZ9 https://t.co/4AqEjvFMxO
