The European Space Agency (ESA) has announced a significant milestone in space exploration: John McFall, a reserve astronaut with a prosthetic leg, has been medically cleared for long-duration missions to the International Space Station (ISS). This marks the first time an astronaut with such a disability has received this medical certification.

“John is today certified as an astronaut who can fly on a long-duration mission on the International Space Station, and I think this is an incredible step ahead in our ambition to broaden the access to society to space,” stated Daniel Neuenschwander, ESA’s director of human and robotic exploration. The certification follows a comprehensive feasibility study, “Fly!”, which addressed concerns about safety and operational issues related to McFall's disability.

“Let’s not underestimate all elements linked to safety procedures when you operate on the International Space Station,” Neuenschwander cautioned. “In all honesty, I was personally expecting some eventual showstoppers there, and I’m really happy to see that we went through that and it’s behind us.”

McFall expressed his pride in the achievement, noting the positive reception from international partners. The “Fly!” study examined over 80 topics, including training, ISS operations, medical considerations, and crew support. Jerome Reineix, the study manager, highlighted that the main challenge wasn't technical but rather involved overcoming preconceived notions about the capabilities of individuals with physical disabilities.

While McFall is cleared for an ISS mission, an assignment hasn't been made yet. He remains eligible for flight opportunities along with other reserve astronauts, including those who have already flown to the ISS through private missions. ESA aims to send all five of its full-time career astronauts on long-duration missions before the ISS’s projected retirement around 2030.

A potential private astronaut mission, potentially commanded by Tim Peake, is also under consideration by the U.K. Space Agency, in collaboration with Axiom Space. McFall confirmed that discussions are ongoing. Liz Johns of the U.K. Space Agency expressed excitement about the achievement and the agency's support for McFall's future endeavors. Neuenschwander emphasized that while the U.K. Space Agency will ultimately decide on a private mission, the crucial point is that McFall is now medically cleared for flight.

“I feel hugely proud,” McFall said. “The reception has been very warm and positive from the international partners there because of the detailed, methodical, exhaustive work we’ve done here with the feasibility study.”
