SpaceX has shifted its focus to constructing a self-sustaining city on the Moon, aiming to achieve this milestone within the next decade. The company highlights the feasibility of launching missions to the Moon every 10 days, with a travel time of just two days, allowing for rapid iteration and development. In contrast, Mars missions can only occur every 26 months, with a six-month travel time, making the Moon a more immediate target for establishing a human settlement. Despite this shift, SpaceX remains committed to its long-term goal of building a city on Mars, planning to initiate efforts in approximately 5 to 7 years. However, the immediate priority is to secure the future of civilization by first focusing on the Moon, which offers a faster path to achieving a self-sustaining extraterrestrial presence.
