Indian-origin NASA astronaut Sunita Williams, alongside her fellow astronaut Butch Wilmore, is facing an extended stay at the International Space Station (ISS) due to serious complications with their return spacecraft which may create dire consequences on their return to earth.
The astronauts were originally scheduled to return within 8 days of their June 5, 2024, launch on Boeing's Starliner, their timeline has now potentially stretched to over eight months.
The Risks In Astronauts Return:
NASA is actively exploring options to ensure the astronauts' safe return, but several potential risks need to be addressed,
- Lack Of Oxygen
- Failure to Re-enter Earth's Atmosphere
- Vaporization upon Reentry
Lack of Oxygen:
According to Rudy Ridolfi, a former commander of US military space systems, there is a risk that the astronauts could face a shortage of oxygen, with just 96 hours of supply remaining.
Failure to Re-enter Earth's Atmosphere:
Another significant concern is the potential failure of the spacecraft to re-enter Earth's atmosphere correctly. Faulty alignment could prevent the capsule from descending properly, leaving it stranded in space indefinitely.
Vaporization upon Reentry:
There is also a risk that the spacecraft could burn up upon reentry if it attempts to enter the atmosphere at too steep an angle. This would put the astronauts' lives in grave danger if the Starliner's heat shield fails under extreme friction and heat.
Health Issues:
Sources say, that in addition to these technical challenges, Sunita Williams, 58, is experiencing vision issues related to long-term exposure to microgravity. This condition, known as Spaceflight Associated Neuro-ocular Syndrome (SANS), affects fluid distribution in the body, leading to blurred vision and changes in eye structure.
