Scientists have discovered that humans will be able to reproduce on Mars because sperm can live there for up to 200 years.
Hopes are getting closer to the possibility of living on Mars, but there are many questions about how humans will reproduce on the Red Planet. Experts previously believed that radiation in space would corrupt our DNA and make reproduction impossible. But that changed when scientists kept the sperm of a rat on the International Space Station for six years and found that it was still healthy.
Liquid from 66 mice was first put into more than 30 glass ampoules in 2012. The scientists then identified the best ones for producing offspring.
3 ampoules were launched to the International Space Station on August 4, 2013, and the remaining three were kept on Earth in Tsukuba, Japan, in roughly the same conditions.
On May 19, 2014, the first ampoule was returned to the ground, examined and compared with samples on the ground, and the scientists decided to proceed with the search.
The second sample was returned on May 11, 2016, two years and nine months after its release. The third sample was returned on June 3, 2019 to Earth, and after examining all the samples, it was found that the sperm were still in good health. Scientists have estimated the time that semen can remain in good condition on Mars, at least two hundred years.
Professor Sayaka Wakayama said: “These experiments have demonstrated the possibility of reproduction on Mars. When the time comes to migrate to other planets, we will need to preserve the diversity of genetic resources, not only for humans but also for pets.”
The discovery came three days after NASA’s Ingenuity helicopter made its seventh successful flight to the surface of Mars, the British Daily Mail reported.
