In August this year, NASA decided to return Boeing’s Starliner to Earth without humans aboard the spacecraft – keeping in view the safety of astronauts Sunita Williams and Butch Wilmore.

NASA is uncertain when Boeing’s Starliner will fly Sunita Williams again, as propulsion issues and delays push its next mission to 2025. Williams will now return on SpaceX's Crew Dragon.

NASA has released the schedule for its commercial launches in 2025, and the Boeing Starliner is slated to get another chance at spaceflight. In a blog post on Tuesday, the agency listed the "Next Starliner Flight" as the last of its three launches in its 2025 schedule.

NASA has officially given SpaceX the next two missions to the International Space Station under its Commercial Crew Program with Boeing’s Starliner still potentially available for a late visit in 2025 if it achieves certification.
