Mars Had Oxygen-Rich Atmosphere 4 Billion Years Ago, Shows New Study


  According to a new study reported in the journal Nature, the atmosphere of Mars could have been rich in oxygen almost 4 billion years ago.
  
  “This result is surprising because while the meteorites are geologically young, around 180 million to 1.4 billion years old, the Spirit rover was analyzing a very old part of Mars, more than 3.7 billion years old.”
  
  Whilst it is possible that the geological composition of Mars varies immensely from region to region the team believes that it is more likely that the differences arise through a process known as subduction – in which material is recycled into the interior.
  
  The scientists suggest that the Martian surface was oxidized very early in the history of the planet and that, through subduction, this oxygen-rich material was drawn into the shallow interior and recycled back to the surface during eruptions 4 billion years ago. The meteorites, by contrast, are much younger volcanic rocks that emerged from deeper within the planet and so were less influenced by this process.
  
  “The implication is that Mars had an oxygen-rich atmosphere at a time, about 4 billion years ago, well before the rise of atmospheric oxygen on earth around 2.5 billion years ago. As oxidation is what gives Mars its distinctive color it is likely that the red planet was wet, warm and rusty billions of years before Earth’s atmosphere became oxygen rich,” Prof Wood said.

The Guardian Revealed An NSA ‘Scoop’ Then Deleted It From The Website
The Guardian released another shocking NSA scoop on Saturday, revealing collusion and mass harvesting of personal communications among the United States and at least six European Union countries — only to delete it from their website hours after publication.
The article, titled “Revealed: secret European deals to hand over private data to America,” was written by Jamie Doward, who reported information from Wayne Madsen, a former Navy Lt. and NSA employee for 12 years.



Doward wrote:
Madsen said the countries had “formal second and third party status” under signal intelligence (sigint) agreements that compels them to hand over data, including mobile phone and internet information to the NSA if requested.
Under international intelligence agreements, confirmed by declassified documents, nations are categorised by the US according to their trust level. The US is first party while the UK, Canada, Australia and New Zealand enjoy second party relationships. Germany and France have third party relationships.
He went on to say that seven European countries and the U.S. have access to a fiberoptic cable network, intercepting phone calls, emails, and user logs from websites. The article describes Madsen as having “been attacked for holding controversial views on espionage issues.” 
That’s a light way of putting it. 
Some of Madsen’s controversial views include the belief that President Obama is secretly a homosexual and that the Boston bombing suspects were government agents. He’s also reported on a “former CIA agent” alleging the 2000 USS Cole bombing was perpetrated not by al Qaeda terrorists, but by a missile fired from an Israeli submarine.
John Schindler, a professor at the Naval War College and intelligence expert, called Madsen "batsh— crazy, to use the technical term."
The pulled article now bears the message, “this article has been taken down pending an investigation” but appears to still be on tomorrow’s front page of the print edition. It was originally published in The Observer, a Sunday newspaper owned by The Guardian and hosted on their website.
