New NASA satellite blasts off on space-map mission

NASA launched Monday a new breed of satellite called WISE on a mission to orbit Earth and map the skies to find elusive cosmic objects, including potentially dangerous asteroids.

The Wide-field Infrared Survey Explorer (WISE) will use infrared rays to map the locations and sizes of roughly 200,000 asteroids and give scientists a clearer idea of how many space rocks loom and what danger they pose.

“When we find them, we will give the information to policy-makers to decide what to do to try to prevent these near-Earth asteroids colliding with our planet,” NASA public affairs officer J. D. Harrington told AFP.

The launch, which had been delayed from Friday after problems were discovered in a rocket booster steering engine, went ahead flawlessly at 6:09 am (1409 GMT) from Vandenberg Air Force Base in California.

WISE, which has been called “the most sensitive set of wide-angle infrared goggles ever,” will orbit 300 miles (500 kilometers) above Earth's surface for 10 months as it hunts for and collects data on dim objects such as dust clouds, brown dwarf stars and asteroids in the dark spaces between planets and stars.

      The oligarchs openly talking about a coup d'état in America?
     

    Multi-millionaire lobbyist Grover Norquist is calling for the impeachment of President Obama. In an interview with the right-wing National Journal - Norquist warned that if President Obama wins re-election and decides to let the Bush tax cuts for the top 2% expire at the end of the year - then Republicans will "have enough votes in the Senate in 2014 to impeach [him]."
     
    What does that mean? It means that the super rich in America - and their political operatives like Norquist in Washington, DC - have now compared a tiny tax increase on the wealthy to high crimes and treason - the only Constitutional basis Congress can use to impeach a President. It sounds like the oligarchs are now openly talking about a coup d'état in America.
