Precious stones – opals – were discovered on Mars

NASA’s Curiosity Rover found opals while exploring Gale Crater. Potentially, these rocks could become a source of water on Mars, reports Space.com. Since opal is mostly water and silica, this may indicate that Gale Crater once contained water. In the future, missions on Mars will be able to use this stone as a source of water.

Also, Gabriel and his colleagues believe that the cracks on the surface of Mars, where the gems were found, were among the last places on this planet where there was liquid water. On Earth, similar stones occur in geysers and hot springs, as well as at the bottom of oceans and other bodies of water. It will be recalled that the Chinese rover discovered traces of floods on Mars that occurred more than 1.6 billion years ago.
