Astronaut Sunita Williams remains on the International Space Station (ISS) longer than initially planned, with her stay expected to last 8-9 months due to a malfunctioning Boeing Starliner.
NASA has revealed that Williams is facing a critical health issue: an accelerated rate of red blood cell destruction during her extended mission in space.
A NASA study reports that astronauts in space experience a significant increase in the destruction of red blood cells, with a rate approximately 54% higher than on Earth. During a six-month mission, this can reach up to 3 million cells per second.
Given Williams’ extended mission duration, this accelerated red blood cell destruction poses a heightened risk, potentially leading to severe health issues.
The excessive destruction of red blood cells can lead to anemia, a condition that impairs oxygen delivery to body tissues. This may result in symptoms such as fatigue, decreased strength, and impaired cognitive and heart function.
Williams has been on the ISS since June 6 and is expected to remain until late February 2025. The extended exposure to space conditions raises concerns about the long-term impacts on her health.
NASA has emphasized the risks associated with anemia, noting that the condition could significantly affect Williams’ physical and mental well-being, complicating her prolonged stay in space.
