'Stranded' NASA astronauts will be carried away on stretchers after return from space. Here's why.
- NASA astronauts Sunita Williams and Butch Wilmore are set to return to Earth after over nine months in space, likely being carried out on stretchers due to temporary changes in the body from space travel.
- Astronauts experience motion sickness upon return due to adaptation to weightlessness in space, prompting precautionary stretcher transport after landing.
- The inner ear's sensory vestibular system is impacted by space travel, leading to balance issues upon re-entry and a sensation of 'space motion sickness'.
- Long durations in space can cause muscle and bone loss due to reduced gravity, leading to muscle atrophy in astronauts.
- To counteract spaceflight effects, astronauts follow a rigorous exercise routine onboard the ISS to maintain strength and readiness for Earth's gravity.
- NASA astronauts Williams, Wilmore, Hague, and Gorbunov are part of the Crew-9 mission returning aboard a SpaceX Dragon spacecraft on March 18.
- The Crew-9 mission faced setbacks with the Boeing Starliner capsule, including thruster malfunctions, but the astronauts are in good spirits and confident about their return.
- Research on the effects of long-term spaceflight on the human body continues, with Russian Cosmonaut Valeri Polyakov holding the record for the longest consecutive time in space at 437 days aboard the Mir space station.
