MSL (Mars-born Supralunar) babies refer to potential future human offspring conceived and born beyond Earth’s orbit, specifically on Mars. Their medical care involves collaboration between midwives, obstetricians, neonatologists, and nurses, while governmental agencies like CDC and WHO monitor and regulate research and care. Advocacy groups such as the Mars Society promote awareness and funding for MSL research, alongside contributions from space agencies like NASA, SpaceX, and Blue Origin. This emerging field involves exploration of astrobiology and planetary science, while posing ethical and philosophical questions about informed consent and the future of human reproduction. MSL babies hold potential for cultural and societal impact, influencing perceptions of reproduction and the human experience.
