Quotes About Space

In Einstein's general relativity the structure of space can change but not its topology. Topology is the property of something that doesn't change when you bend it or stretch it as long as you don't break anything.

We still have a lot of international partner modules that need to get up there to make it truly the international structure that it will be, and that's highly important; we need to get to where the crew size is bigger.

Space and time may have a structure as intricate as the fauna of a rich ecosystem, but on a scale far larger than the horizon of our observations.

There are strong reasons for believing that space goes on beyond the limits of our observational horizon. There are strong reasons because if you look in opposite directions, conditions are the same to within one part in 100,000. So if we are part of some finite structure then, if the gradient is so shallow, it is likely to go on much further.

While American football is very structured and linear and static - where everyone lines up, and there's a burst, and it happens - soccer is like the cosmos. It's like constellations. It's bodies moving in space. It's a very spherical game.

These robotic arms, provided by Canada, have been invaluable in allowing us to build, maintain, and repair space structures, and I've been very fortunate to have gotten to operate them.

Black holes, we all know, are these regions where if an object falls in, it can't get out, but the puzzle that many struggled with over the decades is, what happens to the information that an object contains when it falls into a black hole. Is it simply lost?

With his deeds, not only words, President Obama has revitalized our struggling space program.

Football doesn't depend just on your brain. It's not like on a computer. It depends on your body, too, and sometimes you are tired. Sometimes the opponent closes the space very well and marks you very well. Football depends on many things, not just on you.

NASA is a big organization with a lot of needs that have to be met. So there are a lot of opportunities.

We care about this not being a world where 600 people have gotten on orbit; we want it to be 600,000.

I'm not going into infinity. I'm going into low earth orbit.

We launch when we're kind of in the same orbit that they are in terms of being matched up in inclination in space, and we're just in a little different altitude.

To me, we have never really exploited our ability in low-Earth orbit.

It definitely helps to have been through the arm training flow before and to have used the arm on orbit, and it also gives me the confidence to know that our training facilities are really good, that when you get up there, you feel like you've been there.

You're going very fast when you're on orbit, going around the world once every hour and a half.

We could have human intelligence in orbit around Mars, building things there.

I want people to go into space, to orbit around the world a few times, even to stay there for 24 hours and then come back to where they took off. And I also want people with a low income to be able to do that, not only rich people.

The notion of getting the general public into low-Earth orbit I don't think is far-fetched at all.

The C Mission was the first command and service module. The D Mission was the first mission involving a lunar module in a manned fashion and the command module, and the E would take this lunar module and the command module into a very high elliptical orbit, about 4,000-mile-high orbit.

Putting seven people in orbit should not cost more than flying a commercial jet around Earth.

When we can demonstrate that we can take off horizontally and put something into orbit, then we can begin to talk about increasing the amount of payload. But to say, 'I'm going to do that and put people into orbit' is a real leap.

If you're in space on the way to Mars, and a conflict develops... you can't turn around and go back, because Earth is already gone on its orbit.

Space only becomes ordinary when the frontier is no longer being breached.
