i now recognize honorable marion blakey. >> thank you, chairman hall. thank you for the opportunity to be here again. i am marion blakey, president and chief executive officer of the aerospace industry association, the nation's premier trade association for aerospace. we are very proud of the fact that we are documented space systems and how they're woven into the everyday lives of americans. nasa programs are hallmarks of the character of our nation and leadership. as americans, we're always looking for to the next great frontier. we need to think carefully about changing from current programs. it not only takes the consensus, it takes resources and capabilities. some the we are already building today. had we not committed to the f-1 rocket engine program in the 1950's well before president kennedy's apollo announcement, we would never have gotten to the moon by 1969. this engine enabled a wide variety of human spaceflight missions. how do we keep nasa moving in the right direction? nasa needs stable, long-term investment and steady policy goals. more
