Elon Musk's Starship Updates: From Boring to Exciting

During a discussion at the International Astronautical Congress, Elon Musk stated that it is feasible for SpaceX's Starship to achieve a Mars landing without people on board in three or four years. However, there are numerous challenges that need to be overcome before this can happen, including reaching low-Earth orbit, solving the problem of refilling the rocket with cryogenic propellants in space, recovering the vehicle after reentry into Earth's atmosphere, and navigating through deep space. Musk's vision is to build a self-sustaining city on Mars, and the Starship is central to that goal. SpaceX's current focus is to get the Starship into orbit and eventually recover the rocket's first-stage booster.
