Looking into the reflective image of a vital structure for life and future planetary exploration missions, American scientists have made a surprising breakthrough.
According to Space, a study led by planetary scientist and geologist Tyler Meng from the University of Arizona has discovered a way to observe the glaciers on Mars—structures that space agencies hope contain the most sought-after “treasure”: Water.
On another planet, water not only brings hope for life but also serves as a source of sustenance and energy for future missions, especially in places like Mars, where NASA and the European Space Agency (ESA) expect to establish long-term bases.

However, humans do not have much time or resources when exploring space, making precise mission planning essential. Directly studying glaciers with robots and orbiting spacecraft exploring the Red Planet is quite challenging. But Dr. Meng has found an alternative solution.
The new research indicates that data collected by NASA and ESA show that Martian glaciers are in fact rock glaciers, containing more stones and sand, significantly smaller than Earth’s glaciers but still moving slowly over time, sharing many similar characteristics.
Therefore, observing Earth’s glaciers can serve as a mirror reflecting the very image of Martian glaciers. The research team focused on four rocky glaciers in Colorado, Wyoming, and Alaska, creating a three-dimensional map using radar technology.
“In this process, we have provided the most accurate estimates of the geometry and composition of glaciers to date,” Dr. Meng stated. This data can be used to study the water reserves in those mountainous regions, which may also be present in their Martian “siblings.”
By mapping the models of Earth’s glaciers, scientists can relatively simulate Martian glaciers, which will help in better guiding future missions.
Accessing glaciers to find water sources and clues about life is also considered an easier approach for space agencies compared to reaching ice masses in extremely cold polar regions. This area would also be more conducive for building bases.
