Boeing's Starliner spacecraft is designed to accommodate seven passengers, or a mix of crew and cargo, for missions to low Earth orbit. For the NASA missions to the ISS, it will carry four passengers and a small amount of cargo. Starliner uses a weldless structure and is reusable up to 10 times with a six-month turnaround time. Boeing plans to alternate between two reusable crew modules for all planned Starliner missions. Each flight uses a new service module, which provides propulsion and power-generation capacity for the spacecraft.
