WASHINGTON—Boeing Starliner’s return to Earth from the International Space Station with its first crew of astronauts has been pushed back to June 26, a NASA official said on Tuesday.
NASA astronauts Butch Wilmore and Suni Williams were launched aboard Starliner June 5 and arrived at the ISS following a 24-hour flight in which the spacecraft encountered four helium leaks and five failures of its 28 maneuvering thrusters.
