After years of delay that have put it behind SpaceX, Boeing is set to launch its new Starliner capsule with two crew members to the International Space Station.

It’s the first flight of Boeing’s Starliner capsule with a crew on board, a pair of NASA pilots who will check out the spacecraft during the test drive and a weeklong stay at the space station.

After a bumpy few years, NASA’s Starliner is finally ready for takeoff. The agency says the Boeing spacecraft is set to begin its inaugural crewed mission to the International Space Station (ISS) next week, nearly a decade after originally intended.
