Elon Musk has devoted over two decades to his ambition of reaching Mars through his rocket company, SpaceX. Recently, he has intensified efforts to plan for life on the Red Planet. Musk has instructed SpaceX employees to delve into the specifics of building a Martian city, including designing dome habitats and creating spacesuits to survive the harsh conditions. Additionally, a medical team is exploring the possibility of human reproduction on Mars, with Musk even offering his sperm to help establish a colony. This shift towards concrete planning for a Mars settlement comes as Musk accelerates his timeline, now aiming for one million people living on the planet within the next 20 years, compared to his previous estimate of 40 to 100 years. These initiatives signal a significant step forward in Musk's vision of establishing a self-sustaining civilization on Mars.
