SpaceX postponed the planned launch of four replacement astronauts to the International Space Station on Wednesday, further delaying the long-awaited return of U.S. astronauts Butch Wilmore and Suni Williams. The two have been stuck in space for nine months after their trip on Boeing’s faulty Starliner spacecraft. The latest setback raises concerns over NASA’s crew rotation schedule, as officials work to resolve the ongoing challenges with both Boeing’s and SpaceX’s spaceflight missions. A new launch date has yet to be confirmed.
