The Nature of Things
Escape From Earth
S39 • E9 Feb 18, 1999 45m
In some ways Mars is like Earth: there are clouds, wind, fog and frost. But it's also as cold as Antarctica, its atmosphere is poisonous to humans, and the sky glows pink with billions of suspended dust particles. Some scientists believe the planet's ecology could be re- engineered to make it habitable for Earth's life forms. This would be humanity's greatest adventure, a mission unlike any we've ever known.
