NASA's Kennedy Space Center in Florida hosts a Sustainability Fair in observance of Earth Day.

NASA's Kennedy Space Center in Florida hosts a Sustainability Fair in observance of Earth Day. The fair was held adjacent to the Pathfinder Fitness Trail across the street from the 525-foot-tall Vehicle Assembly Building in Launch Complex 39.

Kennedy Earth Day events included booths by a dozen sustainable companies and environmental organizations, displays on organic gardening, recycling, sustainable materials, alternative fuels and wildlife, and test-drives of several alternative-fuel vehicles. In keeping with the national theme, "Green Cities," the fair provided employees with the opportunity to learn how to do their parts in securing a healthy and sustainable future for their cities and the planet. The space center's sustainability objective is to "promote, maintain and pioneer green practices in all aspects of our mission, striving to be an agency leader in everything we do."
