NASA Glenn Research Center

The men and women of the NASA John H. Glenn Research Center at Lewis Field have, since 1941, been the pioneers and innovators whose work has expanded horizons and opened frontiers for our explorers in air and space. The Center defines and develops propulsion, power, and communications technologies for NASA's aeronautics and space missions. Guided tours of the world-class research facilities are conducted on select Saturdays of each month from April through October.
