European scientists found parts of a huge glacier that once covered most of Mars. High-resolution photos captured by the European Space Agency’s (ESA) Mars Express probe show that much of the glacier has now been covered by wind-blown dust and erosion.The underlying sheet of glacial ice seems to be retreating, which may have contributed to a planet wide altitude difference equivalent to several miles. Mars Express has been orbiting the Red Planet since 2003.

Terrain surrounding the area has ridges and troughs that ESA geologists suspect are associated with the glacier. Scientists suspect that Mars was mostly covered in glaciers multiple times within the past several hundred million years.
This discovery of the glacier on Mars is more evidence that the Red Planet may contain habitats that could potentially support life.
