11. The Valles Marineris: Mars' Grand Canyon

The Valles Marineris is a vast canyon system on Mars, stretching over 2,500 miles long and up to 7 miles deep. Images of this colossal feature, captured by orbiters like Mars Reconnaissance Orbiter, reveal complex geological structures and evidence of past tectonic and erosional processes. These images have reshaped our understanding of Mars' geological history and its potential for past habitability. The Valles Marineris serves as a reminder of the dynamic forces that shape planetary surfaces and the potential for discovering ancient life on Mars.
