CAPE CANAVERAL, Fla. – Kennedy Space Center Director Bob Cabana, right, Florida State Surgeon General John Armstrong, other Kennedy managers and guests prepare for an early morning run at the center's Pathfinder Trail near the Operations and Support Building II at Kennedy Space Center in Florida, to officially kick off National Employee Health and Fitness Month with the NASA Moves! challenge. NASA Moves! challenged the workforce from each of the agency's field centers to engage in at least 20 minutes of activity, or 10,000 steps, each day from May 18-31. About 100 people participated in the kickoff event on the Pathfinder Trail in the heart of the center's Launch Complex 39. The one-third-mile-long gravel walkway traces the iconic shape of a space shuttle orbiter and features a set of exercise stations. The friendly contest is part of NASA's new Health4Life initiative, a Web-based health initiative designed to help employees track their health, fitness and nutrition.

jsc2012e039800_alt (5 March 2012) --- This is a composite of a series of images photographed from a mounted camera on the Earth-orbiting International Space Station, from approximately 240 miles above Earth. Expedition 31 Flight Engineer Don Pettit relayed some information about photographic techniques used to achieve the images: "My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then
