SpaceX, NASA, and other entities are aiming to send people to Mars with the long term goal of establishing a permanent human presence.
Neuroscientist and fiction author Erik Hoel predicted in a blog post published August 25, 2021:
By 2050 there will be an established and growing civilian presence on Mars—a city on the Red Planet. [...] the first city will experience surprisingly explosive economic growth, adding population in a way no Earth city is at the time. It’s very possible someone you know right now will be living on Mars by 2050.
Hoel later doubled-down on his prediction with some nearer-term predictions, including the first human permanent residents and initial base construction by 2030.
