"Seven 'Space Farms' around the country have chosen to honor NASA and the 50th anniversary of human spaceflight with their 2011 corn maze designs," NASA wrote on its Web site. "Using themes highlighting each region's contribution to NASA, the farms are open to the public and feature space-related educational games and activities.

"When the plans were explained to NASA, the agency was happy to contribute design themes and recommendations for each region, as well as education and outreach materials so that the public can learn more about NASA."
