NASA once said that no private company's reaching the red planet without its help. If that's true, then private space corps should be thankful that the agency has a solid plan to get us there. America's space agency has published a document that details the steps it's taking to reach Mars. In it, NASA outlines the three phases of its journey, starting with a step called "Earth Reliant," which is comprised of conducting experiments aboard the ISS and studying how long-duration missions affect the human body. This phase is already ongoing, with the agency testing out different materials and 3D printing on the space station and conducting appropriate research on human behavior and health for the first batch of lucky astronauts.
