 Boeing's Starliner spacecraft and its crew have been in space for more than a month and there's still no return date on the horizon. It's been a much longer trip than the roughly week-long stay initially expected. The vehicle has suffered technical issues that have delayed its return from the International Space Station. The Starliner experienced helium leaks on the first leg of the trip and then several thrusters unexpectedly failed as it approached its docking port at the station.
