Astronauts' return delayed again as Boeing and NASA try to learn more about spacecraft issues

Two astronauts to extend stay on International Space Station as issues with Boeing spacecraft are investigated #

Two astronauts on the International Space Station will remain aboard the station longer than initially planned as engineers on the ground investigate the problems with the Boeing-built spacecraft that transported them. The delay in their return home is due to issues encountered during the spacecraft’s journey, including malfunctioning thrusters and helium leaks. The astronauts will continue to gather data and work through the technical problems while still docked at the space station. Despite the delays, the mission’s overall success is not at risk, according to NASA officials.
