Scientists at the US space agency have reachedNASA“To a new conclusion related to Mars, which is that some living things that live on Earth may live” temporarily “on Mars The surface of the red planet.
Scientists from NASA and the German Space Center released several fungal and bacterial organisms into the stratosphere in 2019 as part of the Marsbox experiment.
The stratosphere is the second main layer of Earth’s atmosphere above the ozone layer, and it has conditions largely similar to Mars, and is the ideal place to send samples to it to see if it will live on Mars.
Scientists have now found in their new research that these microorganisms have proven that it is possible to live on Mars only temporarily to be precise, but they have also discovered that these germs can be revived after returning to Earth.
As for the details of the scientific experiment, the NASA research team placed various fungal spores such as “Aspergillus niger” inside the aluminum container “Marspux” and its name is an abbreviation for (microbes in the atmosphere in order to experiment with radiation, survival and biological results), and the container contained two layers of samples. Including the bottom layer, which is protected from radiation so that “NASA” can separate the effects of radiation from the effects of other environmental conditions.
Then the NASA balloon carried a “Marbox” container to the stratosphere, where the bacterial and bacterial samples were subjected to conditions similar to the conditions of Mars, and were exposed to ultraviolet rays more than a thousand times the levels that cause sunburn.
A member of a team from the German Space Center, Katarina Sims, explains the importance of a fungal bacterium such as “Aspergillus niger” surviving during the Mars journey, saying:
“Through long-range manned missions to Mars, we need to know how the microorganisms associated with humans will survive on the red planet, as some of them may pose a threat to the health of astronauts.”
“In addition, some of these microbes may be invaluable to space exploration, and help us produce food and material supplies independently of Earth, which will be necessary when we are far from home,” she added.
In the past 2020, NASA updated its policies to reflect its stronger commitment to preventing human pollution of the moon and Mars, due to its desire to ensure that it does not take living organisms or other pollutants from Earth to other worlds unintentionally, because that may jeopardize the search for life outside the planet. At risk, as repatriation from other worlds could negatively affect the human environment.
Katarina Simms explained that experiments such as the Marspux mission “are a really important way to help us explore all the implications of space travel on microbial life and how we can direct this knowledge towards amazing space discoveries,” she says.
