WEBDESK (Azaad English): NASA astronauts Sunita Williams and Butch Wilmore have been stranded at the International Space Station (ISS) for over 250 days (approximately 7 months).
In a recent statement, NASA said that the mission to bring back Sunita Williams and Butch Wilmore has been delayed further and they are now expected to return to Earth in March.
The two astronauts have been stuck on the ISS since June due to problems with their spacecraft Boeing’s Starliner.
Initially scheduled to return at the conclusion of their mission in September 2024, their timeline was extended indefinitely after an unforeseen technical issue came about with the spacecraft that was designated for their return.
Their new return date is expected to be 19th March.
However, the two astronauts might find it difficult to adapt to Earth’s gravity once they return to Earth.
Health Challenges Sunita Williams, Butch Wilmore could face:
While the delays have been primarily due to technical reasons, there is another issue that has been concerning for both NASA and the wider astronaut community. Being stuck in space for 7 months could have health risks for the two astronauts.
- Bone Density Loss: In a previous report, experts had confirmed that NASA astronaut Sunita Williams is suffering from bone density loss.
- Muscle Atrophy: Studies have shown that when the human body is exposed to a zero-gravity environment, the muscles start to weaken over time. Extended stays can lead to muscle wasting, which requires physical therapy and exercise regimens post-mission.
- Cardiovascular effects: The abscene of gravity can also affect the cardiovascular system. The heart muscles start to weaken over time as it no longer has to work as hard to pump blood around the body.
NASA has equipped the two astronauts with rigorous exercise routines and monitoring systems to reduce these effects. However, experts still remain concerned about Sunita Williams’ and Butch Wilmore’s prolonged stay in space that will affect their health.
