If a mission requires returning to Earth, what specific ethical dilemma related to parental rights must be addressed concerning a Martian-born child?

Whether the parents are obligated to risk the child’s health in a transition back to $1g$

One of the profound ethical debates surrounding extraterrestrial birth concerns the transition of a child adapted to the Martian environment back to Earth. Since the Martian-born child would never have experienced the full $1g$ environment, moving them back introduces significant physiological risks, particularly to their skeletal density and cardiovascular systems, which developed under reduced gravitational loading. The ethical dilemma forces a conflict between the perceived mission necessity of returning to Earth and the fundamental obligation of parents to protect their non-consenting child from potentially severe health risks associated with that transition.
