NASA, Boeing Push Back Starliner’s Crewed Return To June 18

NASA and Boeing BA.N said they expect to bring Starliner and its first astronaut crew back to Earth from the International Space Station as soon as June 18, later than previously scheduled as mission analysts examine issues that could affect its return.

Boeing’s CST-100 Starliner spacecraft was originally expected to undock on Friday and return to Earth after launching its inaugural crew of two NASA astronauts from Florida on June 5. The mission is a crucial test before the U.S. space agency can certify Starliner for routine flights.

In scheduling Starliner’s return, NASA officials in Houston are juggling various factors: fixes to faulty components on Starliner, weather conditions, and ISS scheduling matters such as spacewalks by other astronauts aboard the station. More changes to Starliner’s return date could be announced during its mission.
