Welcome to the NASA Glenn Research Center. Since 1941, we have been pioneers and innovators who have expanded horizons and opened frontiers for our explorers in air and space. Our Center is responsible for developing and transferring critical technologies that address national priorities in aeropropulsion and space applications. Our work is focused on research for new aeropropulsion technologies, aerospace power, microgravity science, electric propulsion, and communications technologies for aeronautics, space, and aerospace applications.
