FYI: Before we can journey to the stars, we must first go to Mars.
That’s Elon Musk’s philosophy, anyways – and just days ago he revealed new details on his ambitions to colonize the Red Planet, including sending two cargo rockets by 2022 and four rockets (two manned, two cargo) by 2024.
In 40 to 100 years, Musk suggested that up to a million people could live there.
