"From changing size, to crushed immune systems and childbirth complications, humanity colonizing Mars could come with a host of problems for the human body. Elon Musk believes Mars settlement is possible by 2050, but there are considerable challenges and questions that still need to be answered before a permanent presence on the planet can be seriously considered, Rice University professor Scott Solomon believes."
"It is unknown whether a child could be born in space or on another planet, where gravity is weaker or non-existent and radiation levels are far higher than on our pale, blue dot. In Becoming Martian, Solomon explains that there have been no confirmed cases of people having sex in space, and there has been little research on what the development of a fetus and giving birth in a low-gravity environment might look like."
Colonizing Mars would expose humans to low gravity, elevated radiation, and environmental stresses that could impair fetal development, complicate childbirth, and weaken immune systems. There is no confirmed evidence of sexual activity in space and research on conception, embryonic development, and delivery in reduced-gravity settings is minimal. Multigenerational habitation could drive evolutionary changes such as smaller body size and reduced tolerance for Earth's gravity, potentially preventing return migration. Proposed settlement timelines remain speculative given the unresolved reproductive, physiological, and genetic risks that require extensive study before establishing a permanent human presence off Earth.
