By Jennifer Chu – In 1964, physicist John Bell took on this seeming disparity between classical physics and quantum mechanics, stating that if the universe is based on classical physics, the measurement of one entangled particle should not affect the measurement of the other—a theory, known as locality, in which there is a limit to how correlated two particles can be. Bell devised a mathematical formula for locality, and presented scenarios that violated this formula, instead following predictions of quantum mechanics.
However, scientists have also identified several major loopholes in Bell’s theorem. These suggest that while the outcomes of such experiments may appear to support the predictions of quantum mechanics, they may actually reflect unknown “hidden variables” that give the illusion of a quantum outcome, but can still be explained in classical terms. more> http://tinyurl.com/nxe7ge2

NASA Center Renamed in Honor of Neil A. Armstrong
NASA – This photograph shows Neil Armstrong next to the X-15 rocket-powered aircraft after a research flight.
President Barack Obama has signed HR 667, the congressional resolution that redesignates NASA’s Hugh L. Dryden Flight Research Center as the Neil A. Armstrong Flight Research Center, into law. The resolution also names Dryden’s Western Aeronautical Test Range as the Hugh L. Dryden Aeronautical Test Range.
Both Hugh Dryden and Neil Armstrong are aerospace pioneers whose contributions are historic to NASA and the nation as a whole. NASA is developing a timeline to implement the name change.
Neil A. Armstrong was born Aug. 5, 1930, in Wapakoneta, Ohio. He earned an aeronautical engineering degree from Purdue University and a master’s in aerospace engineering from the University of Southern California. He was a naval aviator from 1949 to 1952. During the Korean War he flew 78 combat missions. In 1955 he joined the National Advisory Committee for Aeronautics (NACA), NASA’s predecessor, as a research pilot at Lewis Laboratory in Cleveland.
Armstrong later transferred to NACA’s High Speed Flight Research Station at Edwards AFB, Calif., later named NASA’s Dryden Flight Research Center. As a research project test pilot over the course of seven years at the center from 1955 through 1962, he was in the forefront of the development of many high-speed aircraft. He was one of only 12 pilots to fly the hypersonic X-15 as well as the first of 12 men to later walk on the moon. In all, he flew more than 200 different types of aircraft.

Pathfinding Operations for Orion Spacecraft at Kennedy Space Center
NASA – At NASA’s Kennedy Space Center in Florida, the Orion ground test vehicle has been lifted high in the air by crane in the transfer aisle of the Vehicle Assembly Building. The ground test vehicle is being used for pathfinding operations, including simulated manufacturing, assembly and stacking procedures.
Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of Orion, Exploration Flight Test (EFT)-1 is scheduled to launch in 2014. EFT-1 will be Orion’s first mission, which will send an uncrewed spacecraft 3,600 miles into Earth’s orbit. As part of the test flight, Orion will return to Earth at a speed of approximately 20,000 mph for a splashdown in the Pacific Ocean.

By Mihir Zaveri – As several new private ventures to take people on trips to space come closer to becoming reality, California lawmakers are racing other states to woo the new space companies with cushy incentives.
They are debating a bill now in Sacramento that would insulate manufacturers of spaceships and parts suppliers from liability should travelers get injured or killed on a voyage, except in cases such as gross negligence or intentional wrongdoing. Last year, the state enacted a law that shields space tourism companies such as Sir Richard Branson’s Virgin Galactic from similar lawsuits.
“We’re still in the fledgling part of space flight and space travel, and we need people to be able to take a risk,” said California Republican Sen. Steve Knight, who introduced both state bills. more> http://tinyurl.com/myxh3n6

Feeling the Heat
NASA – Super heated exhaust is a byproduct of engine testing in the Engine Research Building (ERB) at NASA’s Glenn Research Center. Generally, the tests involve burning fuel or using heated air in engine test cells. The exhaust from the tests can approach 1,000 degrees Fahrenheit.
To protect the building systems and for the safety of the occupants, water is sprayed into the hot exhaust to cool the air quickly. The water is then sent to cooling towers to recirculate for the duration of the tests. The buildings in the ERB complex are some of the first buildings constructed at NASA Glenn. This building contains the electrical switchgear that operates support systems for engine testing and other facilities at Lewis Field. Image Credit: NASA Marvin G.
