NASA's Sunita Williams, along with Barry "Butch" Wilmore, is set for an extended ISS mission until 2025, due to Boeing Starliner's technical malfunction, posing significant challenges.
1
Prolonged ISS missions pose significant risks for Sunita Williams, including bone density loss, vision problems, muscle atrophy, and increased exposure to harmful cosmic radiation.
2
In microgravity, Sunita Williams may experience bone loss 12 times faster than severe osteoporosis on Earth, increasing her risk of fractures and other serious bone issues.
3
Sunita Williams could lose up to 50% of her muscle mass and experience heart shape and function alterations due to prolonged microgravity exposure during her extended mission.
4
Sunita Williams may suffer from vision problems due to changes in intracranial pressure, with potential cognitive issues arising from the extended time in the microgravity environment.
5
Daily exposure to cosmic radiation on the ISS significantly increases Sunita Williams' risk of cancer, emphasizing the urgency of resolving the Starliner issues for her safe return.
6
Microgravity increases the risk of kidney stones for Sunita Williams, among other medical concerns that require continuous monitoring during her extended stay on the ISS.
