NASA Astronauts' Return Delayed Due to Starliner Issues

Astronauts Sunita Williams and Barry Wilmore have been unexpectedly extended on the International Space Station (ISS) due to technical issues with Boeing’s Starliner spacecraft, including helium leaks and thruster problems, which have delayed their return. Williams is experiencing Spaceflight Associated Neuro-ocular Syndrome (SANS), causing vision problems linked to prolonged microgravity exposure. NASA is weighing options, including the possibility of utilizing SpaceX’s Crew Dragon for their return, requiring adaptation to different spacesuits. The Starliner mission, initially intended to last just over a week, may now extend up to eight months. Meanwhile, the Polaris Dawn mission, scheduled for August 2024, aims to conduct the first commercial spacewalk, led by pilot Scott Poteet, raising funds for St. Jude Children's Research Hospital.
