Mars was once a warm, wet world like our own
In short: This video explores the history of Mars and the immense challenges of human exploration. It provides context on why this planet is humanity's next great frontier and how it evolved from an Earth-like environment into its current desert state.
Mars is often called the Red Planet, a name tied to the God of War. While it is currently much colder and drier than Earth—with a diameter roughly half that of our own planet—it was vastly different 4.6 billion years ago. During that era, Mars was warm and wet, possessing a thick atmosphere and abundant water; it would have appeared blue to any observer.
The journey to colonize Mars is framed as humanity's most challenging feat, requiring astronauts to operate with total self-reliance. Because there is no room for error or outside help during emergencies, the mission demands peak skill and resource management from a future generation of explorers.
