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. Health4Life also provides an array of resources geared toward increasing physical activity. Photo credit: NASA/Dimitri Gerondidakis
