Summary:
- Boeing's Starliner spacecraft is scheduled to return to Earth without a crew on September 6th, after an unsuccessful attempt to dock with the International Space Station in 2019.
- The uncrewed flight is a crucial test for the Starliner, which is designed to eventually carry astronauts to the ISS, as it will allow Boeing to evaluate the spacecraft's performance and make necessary improvements.
- The successful completion of this test flight will be a significant milestone for the Starliner program, as it works to become a viable alternative to SpaceX's Crew Dragon for NASA's human spaceflight missions.
