The moon and other celestial bodies should be free for exploration and use by all countries. No country should be permitted to advance a claim of sovereignty.

We’ve gotta become the Martians. I’m a Martian – I tell you to become Martians. And we’ve gotta go to Mars and civilize Mars and build a whole civilization on Mars and then move out, 300 years from now into the universe. And when we do that, we have a chance of living forever.

The sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do.

You need to live in a dome initially, but over time you could terraform Mars to look like Earth and eventually walk around outside without anything on… So it’s a fixer-upper of a planet.

I have won this lottery. It’s a gigantic lottery, and it’s called Amazon.com. And I’m using my lottery winnings to push us a little further into space.

In the case of Yugoslavia v. NATO, one of the charges was genocide. The U.S. appealed to the court, saying that, by law, the United States is immune to the charge of genocide, self-immunized, and the court accepted that, so the case proceeded against the other NATO powers, but not against the United States.

Mars is the only place in the solar system where it’s possible for life to become multi-planetarian.

The first stories I wrote when I was 12 were about Mars and landing on Mars.

My vision is for a fully reusable rocket transport system between Earth and Mars that is able to re-fuel on Mars – this is very important – so you don’t have to carry the return fuel when you go there.

You need to be in the position where it is the cost of the fuel that actually matters and not the cost of building the rocket in the first place.

A large majority of Americans believe that the U.N., not the U.S., should take the lead in working with Iraqis to transfer authentic sovereignty as well as in economic reconstruction and maintaining civic order.

The motions of the comets are exceedingly regular, and they observe the same laws as the motions of the planets, but they differ from the motions of vortices in every particular and are often contrary to them.

SpaceX has the potential of saving the U.S. government $1 billion a year. We are opposed to creating an entrenched monopoly with no realistic means for anyone to compete.

Here men from the planet Earth first set foot upon the Moon. July 1969 AD. We came in peace for all mankind.

That’s one small step for a man, one giant leap for mankind.

If we’re going to have any chance of sending stuff to other star systems, we need to be laser-focused on becoming a multi-planet civilisation.

The strategic objective of New Shepard is to practice, and a lot of the subcomponents of New Shepard actually get directly reused on the second stage of New Glenn.

The same thing is to be understood of all bodies, revolved in any orbits. They all endeavour to recede from the centres of their orbits, and were it not for the opposition of a contrary force which restrains them to and detains them in their orbits, which I therefore call Centripetal, would fly off in right lines with a uniform motion.

When we build our own colonies, we can do them in near-Earth vicinity, because people are going to want to come back to Earth. Very few people – for a long time, anyway – are going to want to abandon Earth altogether.

We need to know what the resources of the moon are. We have great evidence now because of different kinds of radar and spectroscopic analysis that people have been able to do. But we really do need to go visit there, and we can do that with a robot craft without any problem.

We’re working on New Glenn, which is our orbital vehicle, but we have in our mind’s eye an even bigger vehicle called New Armstrong.

Some international law specialists compare the invasion of Iraq to the ‚crimes against the peace‘ for which Nazi leaders were indicted at Nuremberg.

Just as a man would not cherish living in a body other than his own, so do nations not like to live under other nations, however noble and great the latter may be.

I sent American troops to Iraq to make its people free, not to make them American. Iraqis will write their own history and find their own way.

The Chinese government wants me to say that for many centuries Tibet has been part of China. Even if I make that statement, many people would just laugh. And my statement will not change past history. History is history.

If we drive down the cost of transportation in space, we can do great things.

We’ve gotta reinvest in space travel. We should’ve never left the moon.

I would like to die on Mars. Just not on impact.

It would take six months to get to Mars if you go there slowly, with optimal energy cost. Then it would take eighteen months for the planets to realign. Then it would take six months to get back, though I can see getting the travel time down to three months pretty quickly if America has the will.

You could warm Mars up, over time, with greenhouse gases.

Nicaragua dealt with the problem of terrorism in exactly the right way. It followed international law and treaty obligations. It collected evidence, brought the evidence to the highest existing tribunal, the International Court of Justice, and received a verdict – which, of course, the U.S. dismissed with contempt.

History shows that, more often than not, loss of sovereignty leads to liberalisation imposed in the interests of the powerful.

I don’t know all the future steps, but I know one of them: we need to build a low-cost, highly operable, reusable launch vehicle. No matter which path we take, it has to include that gate, and so that’s why that’s Blue Origin’s mission.

I thought the attractions of being an astronaut were actually, not so much the Moon, but flying in a completely new medium.

I think a lot of the American people feel more than a little disappointed that the high-water mark for human exploration was 1969. The dream of human space travel has almost died for a lot of people.

America has tossed its cap over the wall of space.

There have to be reasons that you get up in the morning and you want to live. Why do you want to live? What’s the point? What inspires you? What do you love about the future? If the future does not include being out there among the stars and being a multi-planet species, I find that incredibly depressing.

Houston, Tranquillity Base here. The Eagle has landed.

We don’t want an America that is closed to the world. What we want is a world that is open to America.

I feel very strongly that SpaceX would not have been able to get started, nor would we have made the progress that we have, without the help of NASA.

Where the stakes are the highest, in the war on terror, we cannot possibly succeed without extraordinary international cooperation. Effective international police actions require the highest degree of intelligence sharing, planning and collaborative enforcement.

We will have to leave this planet, and we’re going to leave it, and it’s going to make this planet better.

Armed attack has a definition in international law. It means sudden, overwhelming, instantaneous ongoing attack.

No one doubts that innocent men, women and children have been the victims of chemical weapons attacks in Syria. And there’s no doubt who is responsible for this heinous use of chemical weapons in Syria: the Syrian regime.

I would like to fly in space. Absolutely. That would be cool. I used to just do personally risky things, but now I’ve got kids and responsibilities, so I can’t be my own test pilot. That wouldn’t be a good idea. But I definitely want to fly as soon as it’s a sensible thing to do.

SpaceX is only 12 years old now. Between now and 2040, the company’s lifespan will have tripled. If we have linear improvement in technology, as opposed to logarithmic, then we should have a significant base on Mars, perhaps with thousands or tens of thousands of people.

In a very real sense, it will not be one man going to the moon it will be an entire nation. For all of us must work to put him there.

In order for us to have a future that’s exciting and inspiring, it has to be one where we’re a space-bearing civilization.

People will visit Mars, they will settle mars, and we should because it’s cool.

The moon gravitates towards the earth and by the force of gravity is continually drawn off from a rectilinear motion and retained in its orbit.

Space has always fascinated me. As a young boy looking up at the stars, I found it impossible to resist thinking what was out there and if I ever would experience space first-hand.

The Apollo program certainly had no real commercial value. It was done for very different reasons and, I think, very good reasons for the time. It’s an extraordinary achievement of mankind, but it wasn’t sustainable.

It’s not going to do any good to land on Mars if we’re stupid.

I know Elon, we’re very like minded in many ways. We’re not conceptual twins. One thing I want us to do is go to Mars, but for me it’s one thing. He’s singularly focused on that. I think motivation wise, for me I don’t find that Plan B idea motivating. I don’t want a plan B for Earth, I want Plan B to make sure Plan A works.

Millions of people were inspired by the Apollo Program. I was five years old when I watched Apollo 11 unfold on television, and without any doubt it was a big contributor to my passions for science, engineering, and exploration.

For NASA, space is still a high priority.

Perhaps one day I will go into space.

Colonies do not cease to be colonies because they are independent.

It is the stars, The stars above us, govern our conditions.

It is true that SpaceX is partially a government contractor, but it would be unfair to say that SpaceX is entirely a government contractor.

This most beautiful system of the sun, planets, and comets, could only proceed from the counsel and dominion of an intelligent and powerful Being.
