Science center to show off harvest

STENNIS SPACE CENTER, Miss. -- Infinity Science Center on May 7 will show off its first major aeroponically-grown lettuce harvest from the Controlled Environment Agriculture exhibit. The exhibit demonstrates methods astronauts on long-duration space missions can use to grow food, in this case lettuce grown without the use of soil. The prototype exhibit was developed and built by Innovative Imaging and Research with funding from the Chief Technologist's Office and the University of Southern Mississippi's Business and Innovation Assistance Center, in partnership with the Mississippi Enterprise for Technology.
