Mars is life insurance for life collectively: Elon Musk

SpaceX CEO Elon Musk said Mars is life insurance for life collectively. "Eventually, all life on Earth will be destroyed by the Sun. The Sun is gradually expanding, and so we do at some point need to be a multi-planet civilisation because Earth will be incinerated," he added. Elon Musk plans to establish self-sustaining human colony on Mars by 2050.
