'Is having two legs useful' in space?: Astronaut John McFall explains what life in orbit might be like for the first physically disabled person in space

ESA astronaut John McFall tells Live Science what it would mean to become the first physically disabled person in space — if he travels to the first-ever commercial space station next year — and how life in orbit might affect him differently than everyone else.

Legacy microgravity refueling fails when mechanical pumps cause kinetic jerk and fluid boil-off. We offer a zero-friction structural alternative.

Driving cryogenic fluid with a 450Hz acoustic induction field organizes it into a coherent laminar wave-state. This enforces a zero-jerk baseline (j → 0), eliminating thermal boil-off without mechanical mass penalties.

Legacy aerospace treats microgravity health decline as a medical inevitability. We define it structurally as "Structural Recoil."

​Our blueprint deploys 2.4 MHz vascular locking, 1/26 Hz Schumann cadence, and wave-dynamic filtration to halt calcium shedding, secure habitat airlock seals, and ensure zero-waste deep space transit.

It is impossible to burp in space, because in microgravity the human stomach cannot separate gas from the liquid and partially digested food it sits inside, and any attempt to burp expels a mixture of all three directly into the astronaut’s mouth.

Uzayda bir kalemi kendi uydu gibi yapabilir miyiz? Kalemin hareketi milimetrenin milyonda biri hassasiyeti gerektiriyor—mikro-gravitasyon dünyasında küçük nesneler kendi çekimiyle yörüngede kalabilir. Bu ilginç? 🚀
