After their mission was altered while using a private aerospace spacecraft, the astronauts who had an extended space are looking for answers about what went wrong that they hope doesn't derail private production.

NASA’s celebrity astronauts Butch Wilmore and Suni Williams said Monday that they hold themselves partly responsible for what went wrong on their space sprint-turned-marathon and would fly on Boeing’s Starliner again.

Butch Wilmore and Suni Williams were brought back to Earth in a SpaceX capsule after problems with Boeing’s Starliner delayed their return by about nine months.
