Boeing Starliner's crewed debut delayed by NASA.

Boeing's first crewed mission to space aboard its Starliner capsule has been delayed until at least the summer, as last-minute tests and technical debates nixed a plan for an April launch. The Starliner mission is now slated to launch after a private astronaut mission scheduled for May "as teams assess readiness and complete verification work" for the spacecraft, NASA's space operations chief Kathy Lueders said on Twitter. A successful 10-day test mission with Starliner docked to the International Space Station would mark a crucial milestone for Boeing's space unit.
