NASA confirmed the existence of water on Mars six years ago, and six months ago it was able to synthesize oxygen through the Perseverance rover.
We are practically approaching the moment predicted by Elon Musk, who wants the massive colonization of the red planet. Okay, there’s still a lot of water on the Bega until then, but we’re closer, that’s for sure.
From the beginning, all space agencies, not just NASA, have said that a possible Martian colonization is unlikely as long as we do not discover water sources, methods of generating oxygen and being able to use resources on the planet for daily survival.
Although it was mentioned that the first missions will find on the ground supplies previously sent from Earth and will disassemble the ships they get there to build their settlements, it is clear that the food and building materials needed later must come from Mars.
Even possible ships, along with their fuel, which will allow some to return to Earth will have to be built with local materials.
A recent study shows that building materials can be produced from Martian or lunar soil by mixing it with a protein found in the blood and urea (which, incidentally, is not only found in urine, but also in sweat or tears).
