The goal of today’s moon mission is to send astronauts around the moon and have them return alive. It’s a test of life support systems. The long-term plan is to build a moon base where we can mine moon materials, advance science, and test things for Mars missions.
Scientists could not find a way to explain the position of certain minerals on Mars other than by life. But, scientists have been wrong about Mars before, and they may just not know about the non-life mechanisms for creating these patterns.
“Much of the land within the proposed new city limits belongs to the company. Most of the voters are SpaceX employees. Gunnar Milburn, Space X’s security manager, was listed as the town’s first potential mayor. His name has since been replaced by Robert Peden, a vice president at SpaceX. Two other employees, the engineering manager and the senior director of environmental health and safety, would serve as city commissioners. As is the case nationally, Musk would serve as an unelected overseer.”
Mars doesn’t have a magnetic field, so any atmosphere someone tries to terraform will just be blown away by solar winds.
