A Quote by Henry Spencer

Supplying fuel for a Mars expedition from the lunar surface is often suggested, but it's hard to make it pay off - Moon bases are expensive, and just buying more rockets to launch fuel from Earth is relatively cheap.

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.

Elon Musk

Sometimes people wonder why aeroplanes are so cheap and rockets are so expensive. Even the most superficial comparison shows one obvious difference: aeroplane engines use outside air to burn their fuel, while rockets have to carry their own oxidisers along.

Anger is a fuel. You need fuel to launch a rocket. But if all you have is fuel without any complex internal mechanism directing it, you don't have a rocket. You have a bomb

Stanley Bing

Do we really need these big, gigantic, heavy rockets? What if we launch a rocket that's empty, and its sole purpose is to act as a source of fuel on the Moon? Who should build that? Well, I think the U.S. should build that.

Buzz Aldrin

I don't go along with going to Moon first to build a launch pad to go to Mars. We should go to Mars from Earth orbit. We have already been to the Moon; we've already practiced.

Wally Schirra

The great thing about cheap natural gas, again it's cheap, and it provides a cleaner alternative to coal. But it's still a fossil fuel, and because it's still a fossil fuel, it still emits carbon.

Thomas Friedman

Whether solid rockets are more or less likely to fail than liquid-fuel rockets is debatable. More serious, though, is that when they do fail, it's usually violent and spectacular.

Henry Spencer

Tired of burning fossil fuel and polluting the planet? The moon is covered with helium 3, an isotope from the sun that is the perfect fuel for clean fusion reactors.

Homer Hickam

I want to make rockets 100 times, if not 1,000 times better. The ultimate objective is to make humanity a multiplanet species. Thirty years from now, there'll be a base on the moon and on Mars, and people will be going back and forth on SpaceX rockets.

Elon Musk

I’ve always tried to be independent. It’s just my personality. I’ve always been the type to motivate the camp. I’ve always wanted to be the fuel for something—for music, the fuel for my family, the fuel for my best friend. Helping someone with what I’m doing.

Rita Ora

Speaking personally, I want my films to make money, but money is just fuel for the rocket. What I really want to do is to go somewhere. I don't want to just collect more fuel.

Brad Bird

When I finally had the chance to make my childhood dream a reality - as a co-founder and chairman of Moon Express - my goal was to broaden participation in lunar exploration, and connect the common person to its results. We plan to send robotic rovers - not humans - to the Moon to search for precious metals and rare minerals on the Moon's surface.

Naveen Jain

Frequently on the lunar surface I said to myself, 'This is the Moon, that is the Earth. I'm really here, I'm really here!'

Alan Bean

If your child gets asthma, the fossil fuel industry doesn't pay. Or if there's a natural disaster, the bill is paid by the taxpayer, not the fossil fuel company.

James Hansen

Among all the wonderful things we have, we don't seem to have a time to love. And to me that's the fuel, that's the fuel we need to make the engine go.

Stevie Wonder

To send humans back to the moon would not be advancing. It would be more than 50 years after the first moon landing when we got there, and we'd probably be welcomed by the Chinese. But we should return to the moon without astronauts and build, with robots, an international lunar base, so that we know how to build a base on Mars robotically.

Buzz Aldrin
