Life on Mars: Why NASA investigates "greatest discovery of mankind" | Science | News

The possibility of living on Mars is a topic of considerable interest to NASA because of its similarities to Earth, but so far no evidence has been found for past or present life as we know it. However, recent advances indicate that the red planet once flowed with water, which means that Mars may once have harvested life in conditions much warmer and wetter than today. On October 8, 2015, NASA published its strategy for human exploration and colonization of Mars, the concept works through three distinct phases that lead to a fully sustainable civilization on the Red Planet, which they hope to implement sometime in the mid-2030s. .

Three years later, Dr. Garvin revealed what the space agency hopes to find under Amazon Prime & # 39; s "Tomorrow & # 39; s World" documentary.

He said 201

8: "When Mars and Earth were formed more than four and a half billion years ago, they were brothers with all the possibilities of growing up to become what they are like in day.

“So now we have a story about two diverting objects and yet we still share some of the basic building blocks that make them so attractive.

"But Mars is much smaller than Earth and one of the things we have known through the solar system is that size does matter.

" The size of the planet has a bearing on how the planet's atmosphere evolved. "

The narrator explained to viewers why a dwindling atmosphere may have obliterated all living organisms on the surface.

He said:" Mars is in fact six times smaller than Earth, its smaller nucleus is cooler than our planet.

"With time, Mars cooled faster and its volcanoes finally died.

" With nothing to feed it, the atmosphere gradually burst into space, leaving Mars in mercy with cosmic rays and cooling off space

He added: "If we knew the self-replicating molecule, that we would call" life "on a planet, existed on Mars, it would be the greatest discovery in the history of humanity.

"It would change everything."

NASA's Mars mission is divided into three distinct phases that lead to a fully sustainable civilization.

The first stage, which is already underway, is the "Earth Reliant" phase, this will continue to use the International Space Station until 2024, which validates deep space techniques and study the effects of long-term space missions on the human body.

The second stage, "Proving Ground", turns into the cislunar space for most of its tasks, to test the depth of living space and validate the capacity required for human exploration of Mars.

Finally, phase three, the stage "Earth Independent" includes long-term missions on the Red Planet with areas requiring only routine maintenance and the harvesting of Martian resources for fuel, water and building materials.
