Overview
- US astronauts Suni Williams and Barry Wilmore have been stranded on the ISS for nine months due to technical issues with Boeing's Starliner spacecraft.
- Originally intended to stay for just one week, their mission was extended after the Starliner was deemed unsafe and returned to Earth unmanned in September.
- SpaceX's Crew Dragon spacecraft docked with the ISS on Sunday, bringing a new four-member crew to replace the current team, including Williams and Wilmore.
- The return flight for Williams and Wilmore is planned for Tuesday, though weather conditions could cause delays; the spacecraft is set to land off Florida's coast.
- Their extended stay has provided a unique opportunity for research on the physical and mental effects of long-term space missions, including bone density loss and psychological resilience.
