U.S. Neutron Accelerator Sets World Record
500081
The $1.4 billion Spallation Neutron Source facility at the Oak Ridge Lab in Tennessee is the world's most powerful accelerator-based source of neutrons for scientific research -- reaching 183 kilowatts this month. The more wattage, the more neutrons, the more researchers can see as they work to make materials lighter, cheaper and stronger.

Fifty years ago today, the 70-foot (21-meter) tall Juno 1 rocket, a modified Redstone missile, launched the Explorer I satellite, marking the first U.S. built payload to enter Earth orbit. Three of the booster's four stages fell into the ocean while the fourth, which was used to boost Explorer I's velocity, entered orbit behind the satellite.

The U.S. Department of Energy's National Nuclear Security Administration (NNSA) is getting ready to do some serious number crunching at the Los Alamos National Laboratory. The NNSA recently selected IBM to construct the world's first supercomputer using Cell Broadband Engine (B.E.) processors that can perform a mind-boggling 1,000 trillion calculations per second, or one petaflop.
