Growing mouse embryos on the International Space Station (ISS) has shown that mammals may be able to thrive in space, according to Japanese scientists. The researchers sent frozen mouse embryos on a rocket to the ISS in August 2021, where astronauts thawed them and grew them for four days. The embryos developed normally into blastocysts, which are cells that become the fetus and placenta. The study, published in the scientific journal iScience, demonstrated that gravity had no significant effect on the embryos. This research has implications for understanding reproduction in space and potential human colonization missions.
