The Mars Rover Curiosity has been finding many rocks rich in silica, a compound formed from silicon and oxygen, in an area of ​​Mount Sharp on Mars that it’s been exploring for some months. A few months ago the discovery of that kind of rocks was a surprise, so much so that mission managers changed the Curiosity’s research schedule to perform further analyzes. That decision led to the discovery of other silica-rick rocks and to further studies to try to explain their presence.
