Far from being simple deposits of frozen rock, the **glaciers covering the slopes and craters of Mars** contain [mostly **water ice**](https://noticiasambientales.com/ciencia/biomass-el-satelite-que-revela-los-secretos-ocultos-de-los-bosques-el-hielo-y-las-consecuencias-del-cambio-climatico/), according to a study published in the journal *Icarus*.
This finding redefines what was known about the **glacial composition of the red planet** and opens up new possibilities for **human exploration and the use of local resources**.
A standardized approach to studying debris-covered glaciers
The study, led by **Yuval Steinberg** from the Weizmann Institute of Science (Israel), along with senior scientist **Isaac Smith** from the **Planetary Science Institute (PSI)**, aimed to **standardize the analysis methods** for Martian glaciers covered in dust and rocks. Until now, studies were fragmented and difficult to compare.
To achieve this, the team measured:
- **Dielectric property**: speed of radar wave propagation in the material
- **Loss tangent**: level of energy dissipation of the wave in the glacier
These measurements allow to **infer the proportion of ice and rock**, something impossible to determine with surface images alone.
Surprising results: similar glaciers across Mars
Using the instrument **SHARAD (SHAllow RADar)** aboard the **Mars Reconnaissance Orbiter**, the team analyzed five sites scattered across Mars. The result was unexpected: **all the studied glaciers exhibit practically identical physical characteristics**, suggesting:
- Homogeneous formation and preservation mechanisms
- Episodes of widespread glaciation in Martian climate history
“This is important because it indicates that the formation and preservation mechanisms are probably the same everywhere,” explained Smith.
Implications for science and human exploration
Knowing that Martian glaciers contain **over 80% water ice** allows:
- Reconstructing the [climate evolution](https://noticiasambientales.com/medio-ambiente/el-cambio-climatico-acelera-la-desaparicion-de-playas-artificiales-en-el-litoral-de-barcelona/) of the red planet
- Planning the use of water as a local resource in human missions
- Optimizing ice extraction and storage technologies
This scientific advancement not only improves the understanding of **Martian geological processes** but also **brings closer the possibility of sustainable human presence on Mars**.
Next steps: expanding the Martian glacier map
The research will continue with the **identification of additional glaciers** to **refine the comparative model** and delve into the **mysteries of Martian ice**.
Each new site analyzed will contribute to **completing the climate puzzle of the red planet** and **designing more efficient exploration strategies**.
