Scientists are exploring a potential solution for humanity’s survival in space by studying the reproductive abilities of mice frozen-dried in orbit. Teruhiko Wakayama, a professor at the University of Yamanashi’s Advanced Biotechnology Centre, has been developing a device that can conduct rodent in vitro fertilization (IVF) on the International Space Station (ISS).
The goal is to establish a system for preserving Earth’s genetic resources in space, which could be revived even if the planet faces catastrophic destruction. Wakayama believes his work will be crucial as humans spend more time in space, where damaged DNA and lack of gravity can impact reproduction.
Previous studies have shown that freeze-dried mouse sperm can survive for up to 200 years in space, but Wakayama is working to improve this record. His current study aims to determine the impact of space environment on mammalian reproduction and develop a method to preserve reproductive cells at room temperature forever.
While some scientists argue that there are more pressing concerns, such as cancer risk from cosmic radiation, Wakayama’s research could provide valuable insights into human reproduction in space. The potential applications extend beyond humans, including transporting animals like dogs for companionship and livestock like cattle for food, to other planets.
Wakayama hopes his experiments can shed light on whether humans can reproduce and develop normally in the harsh environment of space, providing reassurance for future space travelers.
