Also low temperatures freeze water, making liquid water unavailable. Of these, roughly 8,000 worlds had a success rate of less than 50 in 100, and 4,500 of the planets were habitable less than 10 times out of their 100 simulations. 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.. Liquid water is essential to all life on Earth, and so the definition of a habitable zone is based on the hypothesis that extraterrestrial life would share this requirement. As a main sequence star ages, its interior pressure rises and it becomes more luminous. While not all volatiles make for habitability, water ice can if temperatures are right. 1:10:30.
