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

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

At places like Davos, people like to tell success stories. But their financial success has come with an unthinkable price tag. And on climate change, we have to acknowledge we have failed.

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

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 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.

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.

Taking bold action on climate change simply makes good business sense. It’s also the right thing to do for people and the planet. Setting a net-zero GHG emissions target by 2050 will drive innovation, grow jobs, build prosperity, and secure a better world for what will soon be 9 billion people.

For NASA, space is still a high priority.

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.

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

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

It is hard sometimes to always be at the centre of attention, but when you talk about me you also have to talk about the climate.

The shift to a cleaner energy economy wont happen overnight, and it will require tough choices along the way. But the debate is settled. Climate change is a fact.

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.

We can’t drive our SUVs and eat as much as we want and keep our homes on 72 degrees at all times… and then just expect that other countries are going to say OK. That’s not leadership. That’s not going to happen.

The squandering of oil and gas is associated with one of the greatest tragedies, not in the least resolved, which is suffered by humankind: climate change.

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.

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.

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?

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

The threat to the planet is us. It’s actually not a threat to the planet – it’s a threat to us.

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.

Learning about climate change triggered my depression in the first place. But it was also what got me out of my depression, because there were things I could do to improve the situation. I don’t have time to be depressed anymore.

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.

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.

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

The main message of Climate Revolution is that climate change is caused by the rotten financial system we’ve got, designed to create poverty and rip off any profits for a small amount of rich people. Meanwhile, it destroys the earth.

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

As I’m traveling around, I meet many small children. And when I look at a small and think how we’ve harmed this beautiful planet since I was that age, I feel a kind of desperation, anger, shame. I don’t know what I feel; I just don’t know what the emotion is.

The public is strongly in favor of the Kyoto Protocols, so strongly in favor that a majority of Bush voters thought that he was in favor of it. They are simply unaware.

We’ve got to keep our eye on what’s happening with Russia and North Korea. We cannot lose sight of domestic policy, either. Healthcare. Immigration. Climate change.

I mean, people aren’t continuing like this and not doing anything because they are evil, or because they don’t want to. We aren’t destroying the biosphere because we are selfish. We are doing it simply because we are unaware.

Sweden is not a green paradise, it has one of the biggest carbon footprints.

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.

Would you bet your paycheck on a weather forecast for tomorrow? If not, then why should this country bet billions on global warming predictions that have even less foundation?

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.

If burning fossil fuels was so bad that it threatened our very existence, how could we just continue like before? Why were there no restrictions? Why wasn’t it made illegal? To me, that did not add up.

The vision is to figure out how there can really be dynamic entrepreneurialism in space.

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.

The main message we want to get out there is that climate change is caused by the rotten economic system.

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.

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

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

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.

As you heat the planet up, it’s just like boiling a pot.

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.

We are living in the beginning of a mass extinction and our climate is breaking down.

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

Earth might one day soon resemble the planet Venus.

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

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 think that once you fully understand the climate and ecological emergencies, then you know what you can do as well. And, of course, there’s a lot of things you can do in your everyday life, but we cannot be focusing on these individual things you can do. We have to see the full picture.

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

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.

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.

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.

Houston, Tranquillity Base here. The Eagle has landed.
