奥巴马演讲 A Long Distance Relationship

THE PRESIDENT:  Hey, guys.,COMMANDER ZAMKA:  Good morning from the International Space Station and from the Space Shuttle Endeavour, Mr. President.,THE PRESIDENT:  Well, it's great to talk to you guys.  I wanted to, first of all, just say that we've got a bunch of very excited young people here with us, along with a bunch of somewhat excited teachers.  (Laughter.)  We have one engineer and one member of Congress, so you've got a -- and a whole bunch of press here, so it's a pretty motley（杂色的 ，混杂的） crew.  And one President.,But I just wanted to let you guys know how proud we are of all of you at what you guys have been accomplishing.  I've had a chance to take a look at what Tranquility Module¹ is doing.  Everybody here back home is excited about this bay on the world that you guys are opening up, and Stephen Colbert at least is excited about his treadmill²（踏车
，跑步机） .  (Laughter.),And so we just wanted to let you know that the amazing work that's being done on the International Space Station not only by our American astronauts but also our colleagues from Japan and Russia is just a testimony³（证据，证言） to the human ingenuity⁴（独创性 ，精巧） ; a testimony to extraordinary skill and courage that you guys bring to bear; and is also a testimony to why continued space exploration is so important, and is part of the reason why my commitment to NASA is unwavering（不动摇的，坚定的） .,But instead of me doing all the talking, I wanted you guys to maybe let us know what this new Tranquility Module will help you accomplish.  One of the things that we've done with our NASA "Vision for the Future" is to extend the life of our participation⁵ in the Space Station.  And so we just want to get a sense of the kind of research that you guys are doing, and then maybe I'll turn it over to some young people to see if they've got any questions.,COMMANDER ZAMKA:  Well, thank you very much, Mr. President. It is a large team effort.  In front of you, you have the joint⁶ crew of Endeavour and the Space Station, and we are the ones that are fortunate enough to be able to accomplish this great mission together in space.  But there are many thousands of people around the world that gave the best of themselves over many years in order to have the days that we've been having up here.,For your question, I'm going to turn it over to ISS Commander Jeff Williams.,COMMANDER WILLIAMS:  Well, Mr. President, as you know, the ISS has been under assembly for many years, over a decade now.  And as George said, it's because of the efforts of thousands of people around the world among the international partnerships⁷.,The arrival of this module means several things.  It means, of course, that we -- everybody is aware of this new grand view that we have of the world below us, and that brings a special significance.  But the Tranquility Module also is going to serve as a gym, as a hygiene（卫生
，保健） area, as a place a crew can maintain themselves for a long duration.  And a long duration living and working in space is what the Space Station is all about -- to do the research and the science necessary to take us beyond Earth orbit.,That was the ultimate purpose of the Space Station, and the arrival of this module will enable us to do that.  And it really marks the end of the major assembly of at least the U.S. orbiting segment to -- as we transition into full utilization⁸（利用，使用） of this magnificent orbiting laboratory.,THE PRESIDENT:  Do you guys want to just mention some of the research and experiments that you can conduct on the Space Station that you could not be doing back here at home?,FLIGHT ENGINEER CREAMER:  That's a great question, Mr. President.  Let me start off（出发 ，开始） by saying one of the nice things about where we physically⁹ are right now is that we remove the effects of gravity（重力） , so we're able to do experiments that involve the effect of gravity basically on Earth as we look at what happens with the absence of it.,For instance, when you do combustion¹⁰ studies, flames on Earth burn in a teardrop（泪珠） fashion because the air comes in from underneath¹¹ it and feeds the flame, but we can't do that here since the air doesn't know where up is, there's no convection.  So the flames burn very purely¹² in a ball.,In a similar sense, when we do cellular¹³ research for even -- like for cancer research, for instance, on Earth the cells actually collapse¹⁴ under their own weight and so their growth on Earth are a little bit distorted.  Here, without the gravity effect, we can grow cells very purely and understand the mechanisms¹⁵ by which they are #p#分页标题#e#replicating（折叠
，复制） .,We're also doing metallic¹⁶ research and materials research to help us understand how to make materials on Earth better, but also to find out what materials are better for long-duration missions and traveling beyond Earth's orbit.,Some of the other experiments involve biological, where we actually have, for instance, butterflies up here and we watch the life process of the butterflies.  Many, many experiments up and down the stack are quite exciting when we are able to remove the variable of gravity.,THE PRESIDENT:  Well, some of the things that you talked about are in line with where we want to see NASA going increasingly:  What are those transformational technologies that would allow us to potentially see space travel of longer durations?  If we want to get to Mars, if we want to get beyond that, what kinds of technologies are going to be necessary in order for us to make sure that folks can get there in one piece and get back in one piece and that -- the kinds of fuels that we use and the technologies we use are going to facilitate something that is actually feasible（可行的） ?  And we're very excited about the possibilities of putting more research dollars into some of these transformational technologies.,So we're excited about what you're doing and what folks back on Earth as part of NASA's engineering teams and scientific teams are doing.,What I want to do is give some of these young people a chance to ask a couple of questions, but I'm not sure I've got any volunteers so I'm going to have to turn around -- oh, look.  (Laughter.)  This is a serious bunch here, I can tell.  So I'm going to hand the phone over to the first one -- hold on -- what's your name?,Q    Ruth.,THE PRESIDENT:  This is Ruth, coming from North Carolina.,Q    What are some of the benefits of exploring space as opposed to exploring other places on Earth?,THE PRESIDENT:  Okay.  A pretty serious question, guys.  You better have a good answer -- the NASA folks are sitting here listening.  (Laughter.),MISSION SPECIALIST:  Ruth, I can tell you your curiosity reaches far, and so does ours.  And that's sort of the human spirit, to find out what can humans really do.
One thing that's always been I think amazing to every person who travels in space is that the human body is adaptable¹⁷ to this environment.  But adaptable in what way, and how does the human body and even the human brain adapt to this very, very different environment?  Learning about how we, ourselves, work and how we can handle changes if we go somewhere very different than what we're used to is something that's valuable also on Earth, because our environment changes on Earth, too -- and in terms of health and medicine, we understand better how our own bodies work.  So there’s a lot to be learned.,THE PRESIDENT:  All right, who's next?,Q    Mary.,THE PRESIDENT:  All right, this is Mary coming at you.,Q    What inspired you to become an astronaut?,THE PRESIDENT:  Got any takers on that one?,MISSION SPECIALIST PATRICK:  Mary, hello.  This is Nick Patrick.  The thing that inspired me to become an astronaut was watching the Apollo moon landings many, many years ago with my parents.  I thought I wanted to be a space explorer then and I stuck to my dream.  I stayed in school and I studied hard, and through schoolwork and also an interest in things like sailing and flying I was able to realize my dream.,So I would have some advice to all of you there, which is study really hard in school, listen to your teachers.  They’re full of knowledge and experience that you really can use in whatever path your future life takes you along -- whether it be engineering, science, a job in business, or even space exploration.,THE PRESIDENT:  All right, let’s get -- we have one of our young people from --,Q    From Nebraska.
