Humans will "absolutely" be on Mars in the future, NASA chief scientist Jim Green told USA TODAY. And the first person to go is likely living today, he said.
After the "building blocks of life" were discovered on the Red Planet, life on Mars and living on Mars seems to be less like a scene from the movie The Martian and more like a reality.
"Now, we see Mars is an even better location for having past life," Green said. "It’s just getting better and better."
Mars is more Earth-like than any other planet in the solar system, making it an attractive second option for the human race. There's also a natural beauty on the planet: a grand canyon that measures nearly the entire width of the U.S. and a volcano the size of Arizona.
