Astronaut Sunita Williams Faces Major Issues During The Mission
NASA astronaut Sunita Williams encountered a series of challenges during her unplanned nine-month mission on the International Space Station (ISS). Originally scheduled for only a week, Williams' mission was extended because of a technical problem with the Boeing Starliner spacecraft that was to transport the astronauts home. Together with her fellow astronaut Butch Wilmore, Williams had to navigate a series of obstacles as they adapted to the extended stay, experiencing physical and psychological difficulties in the process.
Mental Stress and Uncertainty
Perhaps the greatest obstacle Williams encountered was emotional stress due to the uncertainty as to when they would return. With the mission well exceeding the planned duration, there was no clear understanding of when they would come back to Earth. This came to be a great source of stress. Williams termed this experience as a "roller coaster," noting the effect it had on her as well as on the families of the astronauts.
Health Problems Due to Space Radiation
Space radiation was also a concern during the long mission. The astronauts are exposed to more cosmic radiation without Earth's protective covering atmosphere, and this increases the risk of developing long-term medical complications like cancer. During her nine-month residence, Williams was subjected to radiation doses of approximately 270 chest X-rays. This increased exposure is one of the greatest risk factors for astronauts on long-duration space stays, again underlining the importance of protective shielding on long-duration missions, particularly with plans to send missions to Mars in the future.
Physical Impacts of Microgravity
Long-term living in microgravity created a series of physical issues for Williams. The prolonged exposure to the weightlessness environment caused muscle atrophy and bone loss, both of which are common issues for astronauts on long-duration missions.In space, the absence of gravitational force will weaken muscles and reduce bone density, and therefore, it would be challenging for astronauts to walk and coordinate after returning to Earth. Also, microgravity makes the body fluids shift, which may lead to elevated pressure in the head and even produce vision issues.
Operational and Maintenance Responsibilities
Aside from these medical and psychological complications, Williams and Wilmore had to perform over 150 science experiments and provide routine maintenance of the ISS facilities. They repaired intricate systems and kept the functioning of the station in check, placing an extra burden of duty and pressure on their already heavy daily schedule. Their efforts made the mission possible, as it helped continue the research in space and develop newer technologies.
Adjustment to Earth's Gravity
Having spent 286 days in space, Williams had to deal with the issue of adjusting to Earth's gravity. This involved regaining balance, coordination, and muscle strength since extended exposure to space can make even simple movements daunting. To help her recover from the physical effects of microgravity, Williams will undergo a 45-day rehabilitation program. This rehabilitation is crucial to her regaining full mobility and strength, and it highlights the challenge of returning to Earth's environment for astronauts after extended-duration spaceflight.
