Lifeforms from Earth might momentarily endure a Mars-like atmosphere, according to a brand-new Nasa research study, which will help scientists to even more understand the possibility of exploiting environments beyond our own planet.
The joint research study by Nasa and German Aerospace Centre (DLR) scientists evaluated the endurance of microbes after launching them into conditions similar to the Red Planet through balloons that drifted up to high elevations, finding that a minimum of a few of them survived the journey.
” We successfully checked a new method of exposing germs and fungis to Mars-like conditions by using a clinical balloon to fly our experimental devices approximately Earth’s stratosphere,” stated DLR’s Marta Filipa Cortesão, joint-lead author of the study.
Released in Frontiers in Microbiology, the research study picked microorganisms connected with life in the world and introduced them into the stratosphere in order to develop conditions closest to those on Mars and almost impossible to recreate in the world itself.
” With crewed long-term missions to Mars, we need to understand how human-associated microorganisms would endure on the Red Planet, as some may posture a health risk to astronauts,” says joint very first author Katharina Siems, also based at the German Aerospace Centre.
” In addition, some microbes could be vital for space exploration. They could help us produce food and product supplies separately from Earth, which will be essential when far from house,” she stated.
The microbes were introduced inside “MARSBOx” (Microbes in Atmosphere for Radiation, Survival and Biological Outcomes experiment) which was kept at a pressure equivalent to the atmosphere of Mars and filled with an artificial environment throughout the mission.

” The box carried two sample layers, with the bottom layer protected from radiation,” discussed Ms Cortesão. “This permitted us to separate the results of radiation from the other tested conditions: desiccation, atmosphere, and temperature fluctuation throughout the flight.
” The leading layer samples were exposed to more than a thousand times more UV radiation than levels that can trigger sunburn on our skin,” she stated.
The study discovered that while not all the microbes made it through the journey, the black mould Aspergillus niger could be revived after it was restored. The same mould has previously been identified on the International Space Station.
The research emphasises the value of microbes in checking out possibilities for life and human survival outside our planet.
