Elon Musk, the CEO of SpaceX and Tesla, mentioned that human colonies on Mars are possible in our lifetime. He also described the options for expanding to a space-bearing civilization and the advantages of Mars. He compared possible spaceships and rockets designs and performance features.
At present, the major challenge that faces engineers and scientists is the need to reduce cost per tonne of transporting materials to Mars by five million percent.
Musk also mentioned that as seen in history, there always is an extinction event at some point that wipes the entire civilization aka doomsday event. Human will be extinct if they stay on Earth forever. And the alternative to that will be to become a multi-planetary species.
Musk is right. There will be an extinction event in the far future, however most of the people are sure that humans won’t need an extinction event if the current trend in population and pollution keeps growing, leading to a man-made catastrophe.
