Watch live: Boeing launches NASA astronauts into space on Starliner space capsule

Boeing is finally ready to send two NASA astronauts to the International Space Station for the first time aboard its Starliner space capsule. The CST-100 Starliner test mission scheduled for Monday night is years in the making and serves as a final demonstration before the spacecraft can be approved for routine trips to orbit. The stakes are high for the third and final orbital flight test for Starliner, as it's the first with a crew on board. Just like Elon Musk's SpaceX capsule, Starliner is intended to be a vehicle that can ferry astronauts to and from the space station as NASA pivots to more partnerships with private industry. But Boeing has largely lagged behind its competitor, which launched its first crewed mission in 2020, according to Reuters.
