It has been recently revealed that the rover `Opportunity' sent to Mars has been able to uncover a scintillating fact about the planet. It has been found that there was once liquid water on the red planet.

There has been the discovery of a bright vein on the planet, which is something that scientists claim to be gypsum. This is formed only when water has been flowing there before.

"This stuff is a fairly pure chemical deposit that formed in place right where we see it. That can't be said for other gypsum seen on Mars or for other water-related minerals Opportunity has found", revealed Steve Squyres, from the Cornell University. This sort of discovery is said to be groundbreaking and it might further be able to reveal many interesting facts about the planet and possibility of life there, which has been speculated since decades.

For now, the scientists have named the gypsum `Homestake' and it has been revealed that after examination, it was found to be made of gypsum. This is the first time such a concrete detail about the possibility of water on Mars has been found and it might prove to be really interesting with the passage of time, with more facts surfacing.

The Opportunity was recently sent by scientists to discover as much possible about Mars. This is because there has been long time speculations made about possible life on the planet, and scientists are working on the same for decades. This rover might be able to find some more groundbreaking facts about the planet, in the time to come.

There has been a new craft sent as well, named Curiosity, which is one of the most high-tech space crafts, ever, and is surely going to help in throwing light on the possibility of life on Mars.
