Scientists are exploring the possibilities of human reproduction in space to prepare for future interplanetary colonisation. Japanese researchers are examining freeze-dried mouse sperm stored on the International Space Station (ISS) to assess its viability in space. This research, led by Professor Teruhiko Wakayama, aims to safeguard Earth’s genetic diversity against potential catastrophes and establish a foundation for extraterrestrial reproduction. With advancements in space missions like NASA’s Artemis programme and SpaceX’s Mars ambitions, understanding reproduction in space could become critical for sustaining life beyond Earth.
