and that's at edwards air force base in california. and these nasa centers are unique in their ability to leverage the complementary and ever-increasing synergies between the space and the aviation systems through these incredibly experienced technical researchers, and they make remarkable advances in aerospace-related disciplines, in things like materials and structures, flight controls, aerospace systems, health management in aerospace systems, in high-speed aerothermal analysis tools. we take for granted when we get on commercial airlines some of the improvements that have been made. we will, where do you think a lot that have came from? it came from nasa, in the research there. and these advances not only accelerate space and aviation systemsystems but also other vey complex systems such as the smart grid, remote medicine and medical robotics, smart cars, a whole bunch of things. so nasa's fundamental aeronautics research capability happens to be also integrated with enabling our future space missions in nasa. and the nation's ai a
