Scientists reported Thursday that NASA’s Curiosity rover has discovered potential constructing blocks of life in an historical Martian lakebed. Hints have been discovered earlier than, however that is one of the best proof but. (June 7)

Humans will “completely” be on Mars sooner or later, NASA chief scientist Jim Green advised USA TODAY. And the primary individual to go is probably going residing in the present day, he mentioned. 

After the “building blocks of life” were discovered on the Red Planet, life on Mars and residing on Mars appears to be much less like a scene from the film The Martian and extra like a actuality. 

“Now, we see Mars is an excellent higher location for having previous life,” Green mentioned. “It’s simply getting higher and higher.”

Mars is extra Earth-like than every other planet within the photo voltaic system, making it a beautiful second choice for the human race. There’s additionally a pure magnificence on the planet: a grand canyon that measures almost your complete width of the U.S. and a volcano the size of Arizona.

The planet may supply people a “model new life with model new vistas,” Green mentioned. 

The plan is to ship somebody to the planet by 2040. But that is depending on fairly a couple of elements.

Here are some obstacles, outlined by Green:

We need to land. Right now, NASA is ready to land a 1-ton car on the floor of Mars. For a human to land, it could have to park about 10 tons on the floor. That car would additionally have to land with precision — primarily not mountains or hills or rocks. 

We would want to blast off from Mars. It’s not a one-way ticket, at the least proper now. That’s why NASA is engaged on a Mars 2020 rover. “Sometime within the subsequent decade, we plan to blast off the floor of Mars and return.”

We would want to put on spacesuits — on a regular basis. Weather on Mars is excessive. The distinction between Monday and Tuesday could possibly be 170 levels. The common temperature is nicely beneath zero. The air can also be largely carbon dioxide — good for planets, unhealthy for individuals. 

We’d need to get used to mud storms. About each 26 months, it is summer season on Mars, that means prime mud storm season. These storms, made up of advantageous mud that will get caught within the environment, can darken daylight to a twilight stage and final months. 

We have to construct a complete infrastructure. “The individuals that will go there are actual pioneers,” Green mentioned. The first people on Mars would want to farm and set up a meals supply. Scientists consider beans, asparagus and potatoes are viable crops for soil there. Homes would additionally should be constructed. Green mentioned 3D printers would possibly be capable of use mud on the planet to create habitats.
