Testing leads to failure, and failure leads to understanding.

We need affordable space travel to inspire our youth, to let them know that they can experience their dreams, can set significant goals and be in a position to lead all of us to future progress in exploration, discovery and fun. Thanks to the X Prize for the inspiration.

Our goal is to show that you can develop a robust, safe manned space program and do it at an extremely low cost.

We'll go back to the moon by not learning anything new.

In 12 or 15 years, there will be routine, affordable space tourism not just in the U.S. but in a lot of countries.

Airplanes were invented by natural selection. Now you can say that intelligent design designs our airplanes of today, but there was no intelligent design really designing those early airplanes. There were probably at least 30,000 different things tried, and when they crash and kill the pilot, don't try that again.

At various times over 20 years, I did preliminary designs for aircraft like the Stratolaunch. For that whole time I was encouraging us to do something that almost everyone else felt you could not do.

By 1931, after a few years' experience of flying scheduled airlines, those planes were operating at roughly 600 times the safety of the space shuttle. I look at safety not in terms of fatalities per passenger-mile, but when you get in and close the door, what is the risk of dying on this flight?

For the industry we're starting now, for suborbital flight, there is no destination, so the spacecraft you go up in has to be large and spacious. That's why SpaceShipTwo is much bigger than SpaceShipOne: It needs to be because you want those six people to be floating around and enjoying themselves.

I drove an electric car for seven years because of its advanced technology, not because I have any concerns about energy resources. I have none at all. And when environmentalists say that global warming is dangerous, unprecedented and that we'll have a tipping point for atmospheric carbon dioxide, it's just nonsense.

I spent about seven years during the Vietnam War flight-testing airplanes for the Air Force. And then I went in and I had a lot of fun building airplanes that people could build in their garages. And some 3,000 of those are flying. Of course, one of them is around-the-world Voyager.

I was shocked to find that there were actually climate scientists who wouldn't share the raw data, but would only share their conclusions in summary graphs that were used to prove their various theories about planet warming. In fact I began to smell something really bad, and the worse that smell got, the deeper I looked.

In the coming era of manned space exploration by the private sector, market forces will spur development and yield new, low-cost space technologies. If the history of private aviation is any guide, private development efforts will be safer, too.

It's not good enough for us to have generations of kids that... look forward to a better version of a cell phone with a video in it. They need to look forward to exploration.

NASA works for the White House. There are many at NASA that wish they were building a modern replacement for the Shuttle. However, they had marching orders to instead work on other things, some of which should have no place in a research organization.

Space travel is the only technology that is more dangerous and more expensive now than it was in its first year. Fifty years after Yuri Gagarin, the space shuttle ended up being more dangerous and more expensive to fly than those first throwaway rockets, even though large portions of it were reusable. It's absurd.

The photographs of space taken by our astronauts have been published all over the place. But the eye is a much more dynamic mechanism than any camera or pictures. It's a more exciting view in person than looking at the photographs. Of course, I personally am sick and tired of hearing people talk like that: I want to see it myself!

There is a rampant tendency in any industry where someone is trying to sell something with a bunch of data, where they cherry pick a little bit... bias a little bit. This becomes quite easy when there is an enormous amount of data to cherry pick from.

There was a wonderful little short four-year time period when marvelous things happened. It started in 1908, when the Wright brothers flew in Paris, and everybody said, 'Ooh, hey, I can do that.' There's only a few people that have flown in early 1908. In four years, 39 countries had hundreds of airplanes, thousands of pilots.

To allow public access to orbit, we would need breakthroughs that would lower the cost by a lot more than an order of magnitude and increase safety by a factor of 100 as compared to every launch system used since the first manned space flight. I think airborne launch will be a significant part of the safety solution.

Tragically, policymakers have thrown horrendous amounts of taxpayer money needed for other purposes at solving an unsubstantiated emergency. It is scandalous that so many climate scientists who fully knew that Al Gore had no basis for his irresponsible claims stood mute.

Usually the wacky people have the breakthroughs. The 'smart' people don't.

Virgin Galactic, which will be operating SpaceShipTwo, will be only one of several spacelines. The competitors for Virgin include the Russians, Bezos's Blue Origin, and possibly Rocketplane Kistler. And likely a couple of others who are smart enough not to tell people what they are doing!

We didn't know the importance of home computers before the Internet. We had them mostly for fun, then the Internet came along and was enabled by all the PCs out there.

When there's ever a breakthrough, a true breakthrough, you can go back and find a time period when the consensus was 'well, that's nonsense!' so what that means is that a true creative researcher has to have confidence in nonsense.

With any luck, by the time NASA's space probe hits Pluto, you'll be booking a spaceflight with a privately run suborbital airline.

When theres ever a breakthrough a true breakthrough you can go back and find a time period when the consensus was well thats nonsense so what that means is that a true creative researcher has to have confidence in nonsense.

Within 25 years, virtual reality meetings will be essentially transparent to being there in person. Once we can do this, the idea of climbing into an aircraft, and burning up huge quantities of fossil fuels to propel our bodies and briefcases full of papers, will seem absolutely backward.

Achievement is not always success, while reputed failure often is. It is honest endeavor, persistent effort to do the best possible under any and all circumstances.

A failure establishes only this, that our determination to succeed was not strong enough.

I hate failure and that divorce was a Number One failure in my eyes. It was the worst period of my life. Neither Desi nor I have been the same since, physically or mentally.

Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.

It's fine to celebrate success but it is more important to heed the lessons of failure.

The key to accepting responsibility for your life is to accept the fact that your choices, every one of them, are leading you inexorably to either success or failure, however you define those terms.

If those committed to the quest fail, they will be forgiven. When lost, they will find another way. The moral imperative of humanism is the endeavor alone, whether successful or not, provided the effort is honorable and failure memorable.

I believe my publisher has shown a great deal of faith in me over a lot of years but I'm not prepared to be so arrogant to say that the long-term literary value of my work would compensate them for a financial failure.

With failure, you just try again.

In God's world, for those who are in earnest, there is no failure. No work truly done, no word earnestly spoken, no sacrifice freely made, was ever made in vain.

The moral turpitude of the boys of today appears to center in their failure to concentrate on any particular objective long enough to obtain their maximum results.

Success and failure are greatly overrated. But failure gives you a whole lot more to talk about.

The failure of Socialism since 1945 is that whilst encouraging us all, the creators of wealth, to produce less through strikes, it has caused us all to demand a higher level of our own product.

The assertion of failure coming from such persons does not mean that Mr. Mill failed to promote the practical success of those objects the advocacy of which forms the chief feature of his political writings.

There are no secrets to success. It is the result of preparation, hard work, and learning from failure.

Failure is not our only punishment for laziness; there is also the success of others.

Don't come home a failure.

However things may seem, no evil thing is success and no good thing is failure.

Failure should be our teacher, not our undertaker. Failure is delay, not defeat. It is a temporary detour, not a dead end. Failure is something we can avoid only by saying nothing, doing nothing, and being nothing.

It is Basic Management 101 that if you reward failure you are going to get more failure, and if you want success you should reward success. But if you look at the way this administration has approached national security, they have kind of got that principle backwards.
