Space Shuttle astronauts were able to walk out of the orbiter due to gravity readaptation and specialized support suits
the verdict
REFUTED
the evidence says no
confidence 9/100
Astronauts returning from space do not immediately experience gravity readaptation; instead, they suffer from significant cardiovascular deconditioning and orthostatic intolerance, requiring specialized garments and assistance rather than simply walking out of the orbiter unaided.

Post-flight orthostatic intolerance and cardiovascular deconditioning actually make astronauts prone to fainting or dizziness upon standing, rather than experiencing immediate gravity readaptation.

Returning astronauts require specialized gradient compression garments precisely because they suffer from orthostatic vulnerability rather than having readily adapted to gravity.
