Astronauts are ready to test out Boeing’s new spacecraft and a Canadian will be talking them through it [Video]

It’s been a decade in the making, but Boeing’s commercial spacecraft is finally launching with its first passengers.

The final test of its crewed spacecraft, called Starliner — also referred to as its Crew Space Transportation 100 (CST-100) — is scheduled to lift off on Monday at 10:34 p.m. ET from the Kennedy Space Center in Florida on board a United Launch Alliance Atlas V rocket.

In the shiny new capsule will be two astronauts: Butch Wilmore, who will be the commander for this mission, and Suni Williams, who will be the pilot.

“It almost feels unreal,” Williams said in a question-and-answer session last week. That’s because Boeing has faced years-long delays after getting the contract from NASA in 2014 to build a new space capsule.
