It’s been a tough few years on planet Earth, with a pandemic ripping across the globe, and an onslaught of record-breakingheatwavesandnatural disasters.
Events like these are good examples of why humans need to finda new place to live, according to proponents of the futuristic idea. Outposts on the moon or Mars could act as an insurance policy against extinction due to catastrophe or self-destruction, they say.
But there’s a lot we don’t know about our ability to survive and thrive in space – including if we can reproduce. Now, freeze-dried mouse sperm, stored aboard the International Space Station (ISS) in a radiation protection box, could help give us a better understanding of mammals’ ability to procreate off Earth.

Maximize your growth potential by staying updated on market movements. When the specimens get back to terra firma next year, Teruhiko Wakayama, a professor at the University of Yamanashi’s Advanced Biotechnology Centre, will study them to determine the impact of the space environment, and if they can be used to create healthy offspring.
Back in his laboratory in Japan, Wakayama is developing a device that will allow astronauts to conduct rodent in vitro fertilization (IVF) aboard the ISS in the coming years. Ultimately, the experiments could help save humankind, he says.
“Our aim is to establish a system for safely and permanently preserving Earth’s genetic resources somewhere in space – whether on the moon or elsewhere – so that life can be revived even if Earth faces catastrophic destruction.”
It may sound straight out of a sci-fi movie, but Wakayama has long been pushing the boundaries with his reproductive studies. In 1997, he and another academic developed a novel method that they used to clone the world’s first mouse from adult cells.
He led a study on the development of mouse embryos in space – something that had previously only been done with creatures like amphibians and fish. And he and his team pioneered a freeze-drying method used to send mouse sperm to the ISS, where it was stored in a freezer for up to six years. When the samples got back to Earth, the researchers rehydrated them and produced healthy baby mice.
From that study, they determined that freeze-dried sperm could stay viable for 200 years in space. Although that’s impressive, Wakayama says it’s “absolutely not long enough for our future.” With his latest space specimens, he’s using a new device to protect sperm stored at room temperature, from radiation, to see if it might be possible to store samples in space indefinitely.
Fordecades,scientists have been launching Earthly creatures into space to study how microgravity and cosmic radiation impact biological processes – including reproduction.
In 1989, for example,32 fertilized chicken eggswere sent into orbit to study how they’d develop without gravity, in an experiment sponsored by the American fast-food chain KFC, and nicknamed “Chix in Space.”

And in 2007, a cockroach named Nadezhda (which means “Hope” in Russian) gave birth to33 offspringconceived in orbit. They were mostly normal, aside from abnormally dark exoskeletons.
“We have seen that most of the specific phases of the reproductive cycle can occur in space, at least in a species or two, not always completely successfully,” saidVirginia Wotring, a professor at the International Space University, a private non-profit institution in Strasbourg, France, devoted to space education.

When it comes to mice, the freeze-dried mouse sperm Wakayama is currently storing aboard the ISS will return to Earth in 2025 for study. “Our goal is to preserve [reproductive cells] at room temperature forever,” he says.
Humans are a long way from becoming a multi-planet species, but we are making progress. In late 2026, the NASA-led Artemis program will return astronauts to the moon for the first time since 1972, where it hopes to develop an ongoing presence. And if SpaceX founder Elon Musk’s predictions are accurate, the first crewed mission to Mars could be on its wayin the next four years.

That means that there are more pressing concerns than reproduction, says Wotring. “There is other information that we need right now in order to care of the astronauts we’re sending to space now,” she says. “That has to take priority.”
But Wakayama believes his work will be crucial as humans spend more time in space. Damaged DNA in sperm and eggs, for example, could pass genetic abnormalities on to the next generation, he says.

And without the directional pull of gravity, a fertilized embryo might not be able to develop properly. “The formation of the nervous system and the development of limbs … we don’t know if this will happen properly in microgravity, where there is no up or down,” he says.
He adds that the work could be replicated and built upon for other species, which could be helpful for transporting animals like dogs for companionship and livestock like cattle for food, to other planets.

His IVF project has been accepted by Japan’s space agency, but the device that will be used to complete the IVF is still under development. He hopes that it will be ready for launch to the ISS within two years.
“In sci-fi movies, people live on other planets and babies are born, but we don’t even know if that’s possible yet,” he says.
He hopes his experiments can help shed light on whether humans can reproduce and develop normally in the harsh environment of space.
“If we can confirm that, it will bring reassurance,” says Wakayama. “And if it doesn’t work, we need to understand how to address that challenge.”
