the budget has got to go up for nasa. that's another reason why i feel very strongly that nasa has to be operating more efficiently and not doing some of the things which would be marginal. you have to focus it on what has to be done. nasa's budget is way too low to do what we've talked about doing here. >> absolutely. and i'd like to point out that i have this study at perdue to be done at the end of april. i've assembled 25 other institutions which are supposed to be unbiased and teach the general background. so if we can come back with a number of questions some of them are yes no maybe. some are tell me shortly. how do we get the public behind what we're trying to do? they're going to know what i'm trying to do briefly because i'm going to show them and i can give them my assumptions. what is the strategy to get the people behind us and what kind of strategy do we need to fund something in 2040? why can't -- why did we refuse them to come to our space station? it doesn't make any sense to me. we should be doing that s

i've had lots of students who have gone to work for nasa, different nasa centers for nasa contractorsbut these kids want to change the world we want to be entrepreneurial. they see the space program as a way that they can be an entrepreneur. they see the smart successful on twitterers put their efforts into helping economy through space. and they see these people as role models that they want to follow. it's almost i think better than when i was a kid in some ways because it's not just nasa doing big projects. it's also the entrepreneurial spirit where they think they can provide economic benefits for the world as well. historic want to tell you come on my second space, all my first flight, second walk. at how we're about 100 miles higher than where the stage was, nowhere near as far as buzz was but i could see the torture of the earth and you could see it in its entirety. it takes uphold field of view but it's deliberate by first spacewalk expect much. on the second what i wanted to see what it was like. there were no word to describe a beautiful plan to was. i will tell you what was

if we look at the organization nasa is also giving many scholarships now. nasa is a space agency. if they are giving scholarships, the funds could be deferred someplace they focus on that. nasa needs to spend their time and focus on those things that inspire people. expiration is that i happen to believe the long-term. but they need to spend their money on this that inspire others to make their scholarships that derive from other places. i work with scholarships all the time. i believe in them. but i think the agency, just one more thing -- but just gas, maybe a couple dozen people working, just focusing on that as opposed to what they did before and letting the inspiration drive those things. another alternative i am raising about it. >> i would like to tell a little story about the months before i left nasa in 1970. i was asked to go down to another center where the next program to follow apollo was being looked at. there were hundreds of errors-based engineers. let me describe what the next system was. this was 1970. we may have flown apollo 12 and maybe start team. it is two s

hopefully more people will have that option but they may not all go on to do that or work for nasa or being involved in it. but i do think exploration would inspire them to stay in school get their education. maybe they'll find stuff along the way that they like even better than space. thank you very much. i want to thank each of the three of you for coming and joining us. this has been a very productive panel. we'll conclude this panel and immediately move on to the second panel that we'll start momently. thank you very much. >> okay. the hearing will come to order. we'll start with mr. albon. >> thank you. chairman cruz ranking member nelson, always good to see you, sir. members of the committee. thank you for this opportunity to provide boeing's perspective on u.s. space exploration goals and u.s. space competitiveness. i want to applaud you both for your opening comments. that spirit of cooperation is heart warming and absolutely essential to our path forward. thank you very much for that. america's economic growth and competitiveness depend on our capacity to innovate stretch fur
