After the recent discovery of extensive fossilized riverbeds on Mars, the idea that the Red Planet could have been habitable 4 billion years ago has gained more traction.
In the study, the scientists used very high-resolution imagery to determine the riverbeds on Arabia Terra. A resolution of 6 metres per pixel, compared to the 100 metres per pixel, confirmed that the features were created by giant rivers on Ancient Mars. The researchers now hope to study the features in greater detail.
Here are some questions:
- Could life still exist on Mars in a form we do not expect?
- What else do we know about Ancient Mars? How do we confirm it?
