Milestone in Space Reproduction: Mouse Embryos Successfully Grown, Paving the Way for Humans

Mouse embryos have been successfully grown aboard the International Space Station (ISS), marking the first-ever study showing that mammals can thrive in space. The experiment, led by researchers from the University of Yamanashi and National Research Institute Riken, aimed to determine if mammalian fetuses can develop normally in microgravity. The embryos were cultured under microgravity conditions for four days and developed into blastocysts with normal cell numbers. The study suggests that humans may be able to reproduce in space, which could become a reality as humanity prepares for long-duration space missions and potential colonization of the moon and Mars.
