Elon Musk, the founder of SpaceX and Tesla, plans to build the first city on Mars by 2050. He posted a statement about it on his Twitter account.
SpaceX will open a second plant in Texas that produces Raptor engines. These engines are used for Starship spacecraft designed to fly to Mars.
Musk said it would take between 800 and 1 000 Raptor engines a year to build a fleet that could build a city on Mars within ten years.
"It will take about 20 years to build the city, so we hope to have it by 2050," Musk said.
