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.
Swedish politician: US is the true cause of the masses of refugees from the Middle East 2015-05-28 20:13
Editors Note: And who controls US foreign policy? Listen to Jeff Gates.
The present Swedish debate about war refugees from the Middle East is an example of peer restricted expression. In the name of political correctness or perceived decency, any questioning of maximum generosity in opening Swedish borders for the refugees is indignantly rejected by the official mainstream. We have a ...
Even if Patriot Act Expires, Government Will Keep Spying on All Americans 2015-05-28 19:52
Government Will Use "Secret Interpretations" to Get Around Legal Prohibitions
Mass surveillance under the Patriot Act is so awful that even its author says that the NSA has gone far beyond what the Act intended (and that the intelligence chiefs who said Americans aren't being spied on should be prosecuted for perjury).
Specifically, the government is using a "secret interpretation" of the ...
The TPP, Monsanto, Rockefeller, Trilateral Commission, Brzezinski 2015-05-28 19:18
All hands on deck for global, economic, corporate dictatorship
There are dots to connect here. They're real, and they're spectacular.
Let me begin with a brief exchange from a 1978 interview, conducted by reporter Jeremiah Novak. He was speaking with two American members of the Trilateral Commission (TC), a group founded in 1973 by David Rockefeller and his intellectual flunkey, Zbigniew Brzezinski.
Video: Who Owns the Federal Reserve 2015-05-28 19:52
It's not like we don't have half a clue who actually "owns" the Federal Reserve, but we just wanted to know, superficially, who the Fed itself claims it is owned by (and, additionally, how the agency justifies its unchecked power).
Apparently the agency never officially answers that question. See for yourself in the video above.
Monsanto's "Discredit Bureau" really does exist 2015-05-28 18:03
Reuters is reporting that Monsanto is demanding a sit-down with members of the World Health Organization (WHO) and the International Agency for Research on Cancer (IARC). This international scientific body is being called on the carpet for reporting that Monsantoâ€™s most widely sold herbicide, which is inextricably linked to the majority of their genetically engineered products, is probably carcinogenic to ...
