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 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.

In just a few hundred years, we will have to cover the entire surface of the Earth in solar cells if we want to continue to grow our energy usage.

As Irving Good realised in 1965, machines with superhuman intelligence could repeatedly improve their design even further, triggering what Vernor Vinge called a ‚singularity.‘

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

I don’t think the human race will survive the next thousand years, unless we spread into space.

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

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

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.

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.

Today we say that the law of relativity is supposed to be true at all energies, but someday somebody may come along and say how stupid we were.

Over time I think we will probably see a closer merger of biological intelligence and digital intelligence.

The most compelling reason for most people to buy a computer for the home will be to link it to a nationwide communications network. We’re just in the beginning stages of what will be a truly remarkable breakthrough for most people – as remarkable as the telephone.

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.

I’ve actually made a prediction that within 30 years a majority of new cars made in the United States will be electric. And I don’t mean hybrid, I mean fully electric.

The boundary between space and the earth is purely arbitrary. And I’ll probably always be interested in this planet – it’s my favorite.

It’s time for the human race to enter the solar system.

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.

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.

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.

Computers are still technology because we are still wrestling with it: it’s still being invented; we’re still trying to work out how it works. There’s a world of game interaction to come that you or I wouldn’t recognise. It’s time for the machines to disappear. The computer’s got to disappear into all of the things we use.

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

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.

I’m never going to go to Mars, but I’ve helped inspire, thank goodness, the people who built the rockets and sent our photographic equipment off to Mars.

I’m trying to construct a world that maximises the probability that SpaceX continues its mission without me.

Some scientists think it may be possible to capture a wormhole and enlarge it many trillions of times to make it big enough for a human or even a spaceship to enter.

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

If humanity doesn’t land on Mars in my lifetime, I would be very disappointed.

Perhaps one day I will go into space.

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.

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.

I think we have a good chance of surviving long enough to colonize the solar system.

It’s important that we attempt to extend life beyond Earth now. It is the first time in the four billion-year history of Earth that it’s been possible, and that window could be open for a long time – hopefully it is – or it could be open for a short time. We should err on the side of caution and do something now.

Once you get into space, you can really unleash a lot of creativity, but the launch itself? I have been through all of the creative ways, and believe me, chemical rockets are the best.

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.

We just think that there are all these different ways that people want to share, and that compressing them all into a single blue app is not the right format of the future.

Science fiction is any idea that occurs in the head and doesn’t exist yet, but soon will, and will change everything for everybody, and nothing will ever be the same again. As soon as you have an idea that changes some small part of the world you are writing science fiction. It is always the art of the possible, never the impossible.

For NASA, space is still a high priority.

It’s time to commit to finding the answer, to search for life beyond Earth. Mankind has a deep need to explore, to learn, to know. We also happen to be sociable creatures. It is important for us to know if we are alone in the dark.

We will build new ships to carry man forward into the universe, to gain a new foothold on the moon and to prepare for new journeys to the worlds beyond our own.

The Eagle has landed.

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.

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

I think we are at the dawn of a new era in commercial space exploration.

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.

Why should man’s first flight to the moon be a matter of national competition? Why should the United States and the Soviet Union, in preparing for such expeditions, become involved in immense duplications of research, construction and expenditure?

The important achievement of Apollo was demonstrating that humanity is not forever chained to this planet and our visions go rather further than that and our opportunities are unlimited.

We’re taking all of the lessons that we have from New Shepard and incorporating them into New Glenn.

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.

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.

I’m trying to get to Mars before everyone else.

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

Science fiction, to me, has not only things that wouldn’t happen, but other planets.

I think the human race doesn’t have a future if it doesn’t go into space.

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

It’s a pity that nobody has found an exploding black hole. If they had, I would have won a Nobel prize.

We fly to 106 kilometers. We’ve always had as our mission that we always wanted to fly above the Karman line because we didn’t want there to be any asterisks next to your name about whether you’re an astronaut or not.

The fastest manned vehicle in history was Apollo 10. It reached 25,000 mph.

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.

Windows 8 is key to the future, the Surface computer.

America has tossed its cap over the wall of space.
