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.

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

Perhaps one day I will go into space.

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

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.

NASA has been one of the most successful public investments in motivating students to do well and achieve all they can achieve. It’s sad that we are turning the programme in a direction where it will reduce the amount of motivation and stimulation it provides to young people.

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

Let’s pray that the human race never escapes from Earth to spread its iniquity elsewhere.

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.

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

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.

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.

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

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.

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

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.

Houston, Tranquillity Base here. The Eagle has landed.

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.

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

The Eagle has landed.

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

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.

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.

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

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.

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.

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

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

For NASA, space is still a high priority.

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

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.

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.

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

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.

The future of humanity is going to bifurcate in two directions: Either it’s going to become multiplanetary, or it’s going to remain confined to one planet and eventually there’s going to be an extinction event.

I have wanted to fly into space for many years, but never imagined it would really be feasible.

If we want to travel into the future, we just need to go fast. Really fast. And I think the only way we’re ever likely to do that is by going into space.

I read ‚The High Frontier‘ in high school. I read it multiple times, and I was already primed. As soon as I read it, it made sense to me. It seemed very clear that planetary surfaces were not the right place for an expanding civilization inside our solar system.

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’m trying to get to Mars before everyone else.

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.

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

Two kids in their dorm room can’t start anything important in space today. That’s why I want to take the assets I have from Amazon and translate that into the heavy-lifting infrastructure that will allow the next generation to have dynamic entrepreneurialism in space, to build that transportation network.

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.

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

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?

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.

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.

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.

America has tossed its cap over the wall of space.

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

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.

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 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.

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

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.

I think it quite likely that we are the only civilization within several hundred light years; otherwise we would have heard radio waves.

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

Space ails us moderns: we are sick with space.

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.
