At what point can an astronaut take off their helmet and why do they need to wear one for take off? (Asked by an actual 5 year old)
In: Physics
I would imagine because it’s like taking off in an airplane x100, your ears pop due to a change in pressure. In a space ship, your body can’t handle the pressure change and the speed at which you are going. Even with a pressurized cabin, your body is still not designed to be in other atmospheres or other levels of high pressure and less oxygen such as a space ship.
