Mars is currently inhabited or, at least, the creatures living there have not been discovered yet. Even humans see Mars as a future replacement for our current planet. However, the survival rates are quite low on the Red Planet because the conditions there are extremes.
What keeps humanity from colonizing Mars
High levels of radiation from the sun and shallow temperatures are two extreme conditions that make Mars unlivable for humans at the moment and not only for us. Neither animal and plants could survive on the Red Planet. However, sending people to Mars is a subject widely discussed in the community of scientists, aiming to colonize the Big Red in the future.
Even NASA, the American space agency, thought of finding a new home on Mars for humanity. Before doing that, though, their goal is that, by 2024, to return to the Moon. NASA is trying to send astronauts to Mars by the 2030s, but until then, they are carrying out several Moon missions as a preparation.
The plan to make Mars habitable
Mars could be inhabited by people, not only receive visits from them thanks to a new plan proposed by a new study. Researchers from NASA’s Jet Propulsion Laboratory (JPL), America’s Harvard University and the University of Edinburgh in Scotland joined forces to find a solution.
You can take a look at the study in Nature Astronomy as it explains how living beings on Mars could be protected by aerogel. This is “the lightest solid material known,” as NASA said and it is made out of a substance found in glass, silica. Because it looks like a cloud and weighs so little, it is sometimes called “frozen smoke.” This material blocks harmful ultraviolet light radiation even though it lets the lights pass.
