Scientists are eager to find more about the planet and the water existence possibility over there as it would indicate whether life ever formed on Mars in its ancient past. If more water sources are found it would help humans survive for future missions on this neighboring planet.
The lake water is not drinkable and lies almost 1.5 kilometers beneath the icy surface in a harsh and frigid environment. Some experts are even skeptical that its water is mixed with a heavy dose of dissolved Martian salts and minerals. The temperature here is below freezing point but the water remains in liquid form due to the presence of magnesium, calcium, and sodium.
The discovery was made using radar instruments. The tool is known as Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS). It was designed to find subsurface water by sending radar pulses that penetrate on the surface and ice caps.
