What Mars Looked Like 4 Billion Years Ago
Thanks to NASA's Curiosity Mars Rover, we are all very familiar with what the surface of the Red Planet looks like right now, but what it looked like 4 billion years ago, in its infancy, is another question. Today, Mars is a barren and dusty wasteland, but scientists believe that 4 billion years ago it may have been something of a paradise, with a thicker atmosphere allowing warmer temperatures, which in turn could support the presence of liquid water.
Soon, NASA will launch its Mars Atmosphere and Volatile Evolution (MAVEN) mission, which it is hoped will help to explain the evolution of the Red Planet's atmosphere. But until then, we can take a look at this beautiful visualization of a more lush, hospitable Mars that may have existed many, many years ago.
The video, created by the NASA Goddard Space Center is not mere speculation, it is actually based off of hard scientific theory on details ranging from the color of the sky right through to the amount of liquid water that could have existed on the planet surface. The most startling thing about the video is how 'Earth-like' Mars may have once looked, causing me to ask, what will become of the pale blue dot we call home? Will Earth face a similar fate to Mars?
