In the original 'Star Trek' TV series, space stations served as deep-space research laboratories, as well as rendezvous points where starships could dock before exploring the unknown. When we were envisioning our own space station, the applications were similar.
In America, we have no means of getting to our own Space Station. We have to pay the Russians to put our people up there to send them into space - rendezvous with the Station and bring them back at the end of their stay, and that to me is just wrong. We're supposed to be the world's greatest space-faring nation, and to cancel our own means of getting there I thought was a mistake, even though it would save some money.
There are several revenue streams that are near and present that could support a private space station, including in-space manufacturing, microgravity research, and tourism - for both individuals and sovereign nation astronauts - and in-space supply logistics.
When Russians were having troubles, the Space Shuttle supported the Space Station Mir bringing up much needed supplies and replacements, critical spares, really. That they were able to keep their space station going for much longer than they would have without us. So, I think that shows the value of international cooperation.
I think I need to continue to think and plan and marry all of the different things that we could do that make transportation in space from the earth to the space station, from the earth to the moon to space stations around the moon to visiting an asteroid.
We're using the space station as a test bed for some of the technologies that are going to enable us to work autonomously in space and hit some of our deep-space exploration goals.
When I started working at NASA and understanding what the capabilities really were of the space station and the space program, one of the biggest draws for me was the ability to do experiments in space. We can do a number of experiments where gravity is actually a variable.
We were trying to do as much science as we could because that was the main purpose of the international space station. But without the shuttle to bring up heavy laboratory equipment and bring back samples, we were limited by what we could do, but I was proud that we actually accomplished more science that was planned for the flight. And I got a chance to do two Russian spacewalks on that flight, I had become an expert in U.S. spacewalks and using U.S. suits and techniques, and this was a chance to put on a Russian Orlan suit and do two construction space flights outside of the space station.
In 2009 I went up on the space shuttle. I was in space for 16 days and docked at the space station for 11 days. The entire crew did five space walks, of which I was involved with three of them. When you're doing a space walk, you always have a buddy with you. It's a very dangerous environment when you're doing a space walk.
As a card-carrying space nerd and NASA's chief scientist, I love space movies, from 'Star Trek' to 'Star Wars' to my all-time favorite - 'The Dish', an Australian comedy that celebrates that first moment when Neil Armstrong stepped down onto the surface of our moon.
I believe that the manned space program can engage the public by advancing the space frontier. Every next mission takes you farther out in space than you were before, either technologically or in terms of distance.
Well, we have two major goals. The most important one is to get the station arm on board the station, because that's this really milestone in the space station building since from now on they will be using this arm to continue building the space station.
Why is there space rather than no space? Why is space three-dimensional? Why is space big? We have a lot of room to move around in. How come it's not tiny? We have no consensus about these things. We're still exploring them.
I think the International Space Station is providing a key bridge from us living on Earth to going somewhere into deep space.
I love sci-fi. Growing up, I was a big fan of the 'Alien' series, 'Star Trek: Deep Space Nine,' etcetera. Plus, anything apocalyptic - 'I Am Legend,' '1984,' 'Battlestar Galactica.'
Because now, you know, it's going to be a number of years yet before we have our own new boosters and new spacecraft to go to our own International Space Station and proceed with all the research that we spent $100 billion putting up there to give us that research capability for the future for people right here on Earth.
While we've taken seeds into space, and astronauts on the International Space Station have eaten lettuce they've grown, we haven't produced fruit in space, so we can't pollinate something.
