A rock crushed under the Curiosity Mars rover’s wheels has dazzled mission scientists in more ways than one.
Mars is supposed to be the Red Planet, but the rock - dubbed "Tintina" - is a brilliant shade of white.
The unusual colour indicates the presence of hydrated minerals that formed when water flowed through the robot’s landing site in ancient times.
Water-bearing minerals in Tintina and elsewhere add to the growing catalogue of water evidence at this location.
Rover team members have been presenting mission findings at the 44th Lunar and Planetary Science Conference (LPSC) in The Woodlands, Texas.
It was also announced that the rover has suffered another computer glitch; Curiosity had already been recovering from a memory problem discovered earlier in the month.
The description of hydrated minerals at Gale Crater follows an announcement last week that Curiosity had found clay minerals in a rock it had drilled. These clays indicate formation in, or substantial alteration by, neutral water.
That is significant for showing that conditions on the Red Planet could have supported life in the distant past, because many rocks studied previously were probably deposited in acidic water.
Speaking here in The Woodlands, near Houston, chief scientist John Grotzinger described Curiosity’s landing site as the first truly habitable environment found on Mars.
"What we’re really excited about is that this is the first time we’ve been able to follow through with a whole suite of different measurements that really demonstrate the place we found at Gale Crater was a very viable, habitable environment," he told BBC News.
Prof Grotzinger added that the team "felt really good" about the Martian location.
The one-tonne Nasa rover has been exploring Gale Crater, near the Martian equator, since touching down in August 2012. It drove over Tintina on 17 January, breaking it open to expose the dazzling white interior.
Is Michael Brown A National Hero? 2014 08 19
From: Brother Nathanael:
I don’t know about you but I revolt against crowning Michael Brown a “national hero.”
Better the crown go to Darren Wilson who according to the Ferguson Police Report shot Brown in self-defense.
Yet there’s already a bounty on his head.
And the media eats it up.
For whether it’s NBC; CNN …or the New York Times; the spin is that ...
