Water on Mars in its past
Water on Mars. Image 2 of 4. Artwork of water and clouds on Mars billions of years ago. It is thought that liquid water existed on Mars early in its history, but was lost to space over time. This may have been due to Mars weak gravity, thin atmosphere and weakening magnetic field. If liquid water did exist on Mars, there is the possibility that life may have begun there. Numerous probes have so far failed to find any evidence for this, however. In the future, it may be possible to return Mars to this wet state artificially, and create an environment suitable for life once again. This process is called terraforming.

EDITORS COMMENTS
This artwork titled "Water on Mars in its past" takes us back billions of years ago, depicting a scene that might have existed on the red planet. The image showcases water and clouds gracefully adorning the Martian landscape, hinting at the possibility of liquid water's existence during Mars' early history. However, as time passed, this precious resource was lost to space due to various factors such as Mars' weak gravity, thin atmosphere, and weakening magnetic field. Despite numerous probes searching for evidence of life originating from this ancient water source, none have been successful so far. Nevertheless, scientists speculate about the potential future of Mars through terraforming - a process that could artificially restore the planet's wet state and create an environment suitable for life once again. This ambitious concept holds promise for transforming Mars into a habitable world. The thought-provoking illustration reminds us of our fascination with planetary exploration and our relentless pursuit to uncover extraterrestrial secrets. It serves as a reminder that even though we may not have found conclusive evidence yet, there is still hope in unraveling the mysteries hidden within our neighboring celestial bodies like Mars.
