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

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.

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

I think there are more politicians in favor of electric cars than against. There are still some that are against, and I think the reasoning for that varies depending on the person, but in some cases, they just don’t believe in climate change – they think oil will last forever.

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.

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.

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.

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.

I want to use my position of leadership to help move along at a faster pace what I believe and know the Obama administration wants to do around the urgency of climate change.

I’m a radical environmentalist; I think the sooner we asphyxiate in our own filth, the better. The world will do better without us. Maybe some fuzzy animals will go with us, but there’ll be plenty of other animals, and they’ll be back.

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’ve grown accustomed to hotels and drastic climate change.

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.

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 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.

People are unaware of what is going on. When I talk to people, they know the basics, they know the planet is warming because of greenhouse gases… but they don’t know the actual consequence of that.

I talk to fashion designers and say I want some money to save the rainforest, and they say, ‚Oh, I agree with you completely Vivienne. Yes, climate change, it’s definitely happening,‘ but they don’t feel that they can do anything about it; they don’t even think ‚Well let’s stop it!‘

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.

Solving the climate crisis is the greatest and most complex challenge that homo sapiens have ever faced. The main solution, however, is so simple that even a small child can understand it. We have to stop our emissions of greenhouse gases.

The climate crisis is both the easiest and the hardest issue we have ever faced. The easiest because we know what we must do. We must stop the emissions of greenhouse gases. The hardest because our current economics are still totally dependent on burning fossil fuels, and thereby destroying ecosystems in order to create everlasting economic growth.

Many people say that this is not an easy issue, we cannot just say that this is how it is, it’s not black and white. But I say that this is black and white. Either we stop the emissions or we don’t. There are no gray areas when it comes to survival.

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.

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

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.

If there was an observer on Mars, they would probably be amazed that we have survived this long.

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.

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.

Climate change is a terrible problem, and it absolutely needs to be solved. It deserves to be a huge priority.

We shouldn’t be saying ‚Save the planet‘; we should be saying: ‚Save viable conditions in which people can live.‘ That’s what we’re dealing with here.

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.

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

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.

The thing that’s made me open my eyes to what was happening to the environment and climate was films and documentaries.

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.

At first when I heard about climate change, I was a climate denier. I didn’t think it was happening. Because if there really was an existential crisis like that, that would threaten our civilisation, we wouldn’t be focusing on anything else. That would be our first priority. So I didn’t understand how that added up.

The symbolism of the climate strike is that if you adults don’t give a damn about my future, I won’t either.

Now, we put out a lot of carbon dioxide every year, over 26 billion tons. For each American, it’s about 20 tons. For people in poor countries, it’s less than one ton. It’s an average of about five tons for everyone on the planet. And, somehow, we have to make changes that will bring that down to zero.

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.

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.

Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the drug store, but that’s just peanuts to space.

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

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 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 want the politicians to prioritise the climate question, focus on the climate and treat it like a crisis.

Land on Mars, a round-trip ticket – half a million dollars. It can be done.

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.

It’s not as though we can keep burning coal in our power plants. Coal is a finite resource, too. We must find alternatives, and it’s a better idea to find alternatives sooner then wait until we run out of coal, and in the meantime, put God knows how many trillions of tons of CO2 that used to be buried underground into the atmosphere.

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

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.

People tell me that they are so hopeful when they see me and other children ‚school-striking,‘ and they say, ‚Oh the children are going to save us.‘ But no, we aren’t. We are too young to be able to do that. We don’t have time to wait for us to grow up and fix this in the future.

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.

Earth might one day soon resemble the planet Venus.

Nothing is being done to stop the climate and ecological emergency from happening and to secure the future wellbeing for future generations.

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.

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.

At Virgin, we have always backed the power of the entrepreneur and inventor to find solutions to tricky problems. Why should climate change and the battle against carbon be any different?

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

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

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

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

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.
