The Spectacular Sea of Salt: Salar de Uyuni
The largest and highest salt flats in the world, Salar de Uyuni in Bolivia, has to be seen to be believed. Quite an unearthly experience, your attention is first drawn to the mysterious mounds of sand that dot the landscape. But that’s not all. Salar de Uyuni even has rock trees and a locomotive graveyard to boot.
You may not have heard of Uyuni, but our astronauts have. It is used as a target for calibrating and testing remotes sensing systems on satellites in orbit. Why? It is big – very big – and has an incredibly smooth surface which is highly reflective when it is covered in water, making it perfect for that task.
