VANDENBERG AIR FORCE BASE, Calif. -- Inside the Astrotech payload processing facility at Vandenberg Air Force Base in California, Orbital Sciences technicians conduct an ultraviolet light cleanliness inspection on the payload load isolators of the Taurus XL launch vehicle for the Orbiting Carbon Observatory, or OCO, before installation on the ballast ring. From left are Dana Frederic, Bill Nelson and Randy Bone. The OCO is an Earth-orbiting mission sponsored by NASA's Earth System Science Pathfinder Program. The observatory will collect precise global measurements of carbon dioxide in the Earth's atmosphere. Scientists will analyze the data returned to better understand the natural processes and human activities that regulate the abundance and distribution of this important greenhouse gas. Launch is targeted for Feb. 24 from Space Launch Complex 576-E at Vandenberg. Photo credit: NASA/Richard Nielsen, KSC KSC-2009-1624

Production of butylene glycol. Dr. Lynferd J. Wickerham selects the bacteria that will convert corn into butylene glycol at the Northern Regional Research Laboratory of the U.S. Department of Agriculture at Peoria, Illinois. This is one step in the research that led to the development of a fermentation process for converting corn into butylene glycol, which has proved successful on a semi-commercial scale. Butylene glycol, hitherto a relatively rare chemical, can be used in making anti-freeze for automobiles and in the production of commercial solvents for various purposes. In the laboratory, the scientists have succeeded in turning butylene glycol into butadiene, from which synthetic rubber can be made. The next step is to find a way to carry out this process on a larger scale
