Mars has been a huge topic of conservation for many space-loving people out there, and for a good reason! It is a planet that has a huge potential to become our second home! Over the last fifty years, the idea that water exists on Mars went from being a mere speculation to a proven reality. This has made a drastic impact on how scientists view space and space travel. This list contains ten different discoveries made over the years about water on Mars.
One of the strongest evidences towards water on Mars was actually an accidental discovery. When one of the Spirit rovers wheels malfunctioned, it began to dig deep into the dirt. Dirt that was turned up by the wheel was tested and scientists found a lot of silica in it. Silica is a substance used in quartz and window glass – and it requires water to form.
