Efforts to find a new planet other than Earth as a new location for human life are still being carried out.
Mars is one of the planets that is predicted to be the most suitable to replace Earth if humans have to move to another planet.
Recently, researchers discovered a new fact that is quite interesting to discuss.
According to researchers, humans have a high chance of living on Mars because sperm can survive there for up to 200 years.
This new fact opens up new hope for many people. At least, efforts to create new colonies in space are starting to show a bright spot.
Even so, there are still a number of questions that still need to be answered by researchers. Take, for example, the question of how people can have sex on Mars in microgravity.
Previously, experts thought that radiation in space would damage human DNA, making it impossible for reproduction to occur.
This assumption immediately changed when the researchers tried to store mouse sperm on the International Space Station (ISS) for six years. As a result, the sperm was found to be healthy.
Sperm from 66 mice were put into more than 30 glass tubes in 2012. The scientists then selected the best sperm that could produce offspring.
Three sperm were then launched to the ISS on August 4, 2013. While the other three sperm were stored in Tsukuba, Japan, under almost the same conditions.
The hope is that the sperm can be tested for exposure to malignant radiation from outer space.
The first box was returned to Earth on May 18, 2014 to see if this test worked well or not.
After the samples were examined and compared, the researchers decided to continue with the experimental program.
Then, the second box was returned on May 11, 2016, exactly two years and nine months after it was launched from the first day.
While the third box, returned on June 3, 2019 or five years and 10 months later. This is the longest space experiment in the history of biological research.
According to the Daily Mail , Professor Sayaka Wakama said the experiment yielded genetically normal results.
He hopes that this discovery will become an important asset for mankind.
"When the time comes to migrate to other planets, we need to maintain diversity, not only for humans, but also for pets," he said.
The research itself comes three days after a NASA helicopter named Ingenuity made its seventh successful flight on Mars.
The helicopter successfully landed at an airfield previously only visible to the Mars orbiter.
The trip took place on June 6, about two weeks after his last flight. The drone also took some black-and-white photos during the flight.
