"Concerns over British Astronaut's Prosthetic Leg's Potential Threat to ISS Crew"
Experts have raised concerns that British astronaut John McFall's prosthetic leg could release toxic gases in the confined environment of the International Space Station (ISS). McFall, the world's first parastronaut, had his right leg amputated following a motorcycle accident in 2000. The European Space Agency (ESA) is now conducting tests on his prosthetic leg to ensure it does not emit dangerous gases over time. The feasibility study aims to assess the impact of being an amputee in space and find solutions to any potential problems. A decision on McFall's participation in a space mission will likely be made after the study concludes in 2025.
