After a treacherous journey, NASA’s Curiosity Mars rover has reached an area that is thought to have formed billions of years ago when the Red Planet’s water disappeared.
This region of Mount Sharp, the Curiosity rover’s Martian stomping ground, is rich in salty minerals that scientists think were left behind when streams and ponds dried up. As such, this region could hold tantalizing clues about how the Martian climate changed from being similar to Earth’s to the frozen, barren desert that Curiosity explores today.
