WASHINGTON, May 29: NASA astronauts Butch Wilmore and Suni Williams have successfully concluded their physical rehabilitation following an unexpected nine-month stay aboard the International Space Station (ISS). Their mission, initially planned as an eight-day test flight aboard Boeing's Starliner capsule, was extended due to propulsion system issues, leading to their prolonged stay in space.

Upon returning to Earth in March, Wilmore and Williams underwent a 45-day recovery program to readjust to Earth's gravity, a standard procedure for astronauts after long-duration missions. During this period, they engaged in daily physical therapy sessions with NASA's medical team while resuming their roles in supporting Boeing's Starliner program and NASA's space station operations.

Both astronauts have reported gradual improvements in their physical well-being. Williams noted a return to her usual early morning routine, while Wilmore experienced relief from pre-flight neck and back discomfort that had resurfaced upon reentry.

The extended mission highlighted the challenges of long-duration spaceflight, including muscle atrophy and balance issues. In response to the Starliner's technical difficulties, NASA is considering conducting another uncrewed test flight before allowing crewed missions to resume.

As they continue their recovery and contribute to ongoing spaceflight programs, Wilmore and Williams remain dedicated to advancing human space exploration and ensuring the safety and effectiveness of future missions.
