Boeing's Starliner spacecraft, scheduled to return from the ISS with its first crew, faces a postponed return without a new date, raising uncertainty. The crew, Butch Wilmore and Suni Williams, launched on June 5 for a final demonstration. Technical issues, including thruster failures and helium leaks, have caused delays. Boeing's Starliner program has faced challenges, including software glitches and design problems. NASA and Boeing are working to understand these issues before the spacecraft's return, which requires at least 12 of its 28 thrusters to be operational for a safe flight.
