October 7 is target launch date for resupply mission to ISS

NASA and SpaceX have announced October 7, 2012, as the target launch date for SpaceX's first resupply mission to the International Space Station (ISS). The launch of the Falcon 9 rocket and Dragon spacecraft is scheduled for 8:34 p.m. EDT from Cape Canaveral, Florida.

Norman Augustine to chair Fermilab director search committee

Norman R. Augustine, the retired chairman and chief executive officer of Lockheed Martin Corp., has agreed to chair the search committee for the new Director of Fermilab.

JSC’s historic vacuum chamber ready to test Hubble’s successor

An upgrade eight years in the making is complete, and Johnson Space Center is now home to the only vacuum chamber in the world that is large enough and cold enough to provide a space-like environment for the James Webb Space Telescope.

Fermilab physicists rework plans for LBNE

On August 28, officials from Fermilab presented their revised plan for the first stage of the Long-Baseline Neutrino Experiment (LBNE) to a federal advisory panel.

X-rays reveal spin waves in two-dimensional high-temperature superconductors

Physicists working at Brookhaven National Laboratory and Switzerland’s Paul Scherrer Institute have revealed key quantum characteristics of high-temperature superconductors, demonstrating new experimental methods and breaking fundamental ground on these mysterious materials.

Larsen & Toubro Ltd to manufacture ITER Cryostat

The ITER cryostat will be the largest high-vacuum pressure chamber ever built. On August 17, a contract for the manufacturing of the 3,800-ton steel structure was signed with the Indian company Larsen & Toubro (L&T) Ltd.

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...
