How is the health of the 2 astronauts stuck for 9 months?

Astronaut Wilmore said he overcame the symptoms of vestibular disorders, but astronaut Williams still had difficulty waking up in the morning, persistent fatigue, and even exhaustion.

American astronauts Butch Wilmore and Suni Williams are recovering after returning to Earth in March 2025, ending a test mission of Boeing's Starliner spacecraft that was unexpectedly extended to nine months due to technical problems.

The mission was originally scheduled to last only eight days, but technical problems prevented the spacecraft from making the planned return trip. However, a nine-month rescue effort resulted in the two astronauts returning safely to Earth earlier this year.

After returning, astronauts Wilmore and Williams underwent 45 days of physical therapy to restore muscle tone, balance and basic daily functions. Each day, they spent at least two hours with rehabilitation specialists from the National Aeronautics and Space Administration (NASA) medical team.

In addition, both are gradually getting used to the increasing workload within the framework of Boeing's Starliner program, NASA's unit operating the International Space Station (ISS) in Houston and its affiliated research teams.

Sharing with the press, astronaut Wilmore said that gravity was a big obstacle in the early stages of treatment. However, thanks to time and the right treatment, he overcame the symptoms of vestibular disorders.

Meanwhile, astronaut Williams said she had difficulty waking up in the morning, persistent fatigue, and even exhaustion - post-space effects that made the recovery process more challenging.

Wilmore also revealed that before the flight, he had suffered from severe neck and back pain that made it difficult to turn his head completely. However, the zero-gravity environment of space helped alleviate the pain. Unfortunately, these symptoms returned shortly after he returned to Earth.

According to experts, the human body - which evolved for millions of years in the Earth's gravity - is not "designed" to adapt to the environment of space. Weightlessness can cause many physiological changes such as muscle atrophy, changes in blood circulation and many other health problems.

In addition, living in a confined space, exposure to high radiation and lack of atmospheric protection also greatly affect the health of astronauts.

The incident that left two astronauts stranded on the ISS has forced NASA to return the Starliner to Earth without a pilot. In this context, Boeing - the developer of Starliner - is facing great pressure, especially as NASA considers the possibility of requiring an additional unmanned test flight before granting permission for further human missions.

Boeing has spent more than $2 billion on the Starliner program, including $410 million for an unmanned test flight in 2022, after an initial failure in 2019. NASA said the results of Starliner's technical tests this summer will determine whether the spacecraft is fit to continue carrying humans.
