Boeing’s CST-100 Starliner Crew Flight Test vehicle will be the second to go to space, and the first to fly crew on a test flight to the International Space Station. In this picture, the upper dome is actually mated to the lower dome, but only electronically. The Boeing team is making sure all the hardware and software in the two pieces are working together correctly, before they will be put together for a final time. Then, the interior of the spacecraft will be outfitted and the outside will be covered with thermal protection.
