David R. Brower Quotes

Man must at all costs overcome the Earth's gravity and have, in reserve, the space at least of the Solar System.

Planets look about the same here as they do to you on the Earth because we really aren't that much closer. Our home, the International Space Station, orbits around the Earth at about 200 miles.

I've put a lot of my life into making it possible to fly in space at all.

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 hope that by 2050 the entire solar system will have been explored and mapped by flotillas of tiny robotic craft.

I've been lucky enough to fly to space twice.

So most astronauts getting ready to lift off are excited and very anxious and worried about that explosion - because if something goes wrong in the first seconds of launch, there's not very much you can do.

You don't go into space just for the science. Economically, it is not worth it. I think the reason we should be in space is for the exploration; it's the human endeavour.

It's important to bring things back from the Space Station because, unlike somebody living at the house where the garbage truck comes by twice a week, they don't have that in space.

The purpose of going to Mars is for humans to first begin to occupy, permanently, another planet in the solar system. The astronauts or pilgrims, whatever you might call them, are going to be very historically unique human beings.

To try to really land a spacecraft really on another world is really difficult, and if we lose that ability, it's going to be heartbreaking.

With every inch of land on Earth now catalogued by our satellites, the stars are the next place we as a species must travel. And with a booming world population that will hit 9.1 billion in 2050, large-scale space travel may become a necessity.

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

The rocket had worked perfectly, and all I had to do was survive the reentry forces. You do it all, in a flight like that, in a rather short period of time, just 16 minutes as a matter of fact.

You wouldn't want to land on the Moon and launch to Mars. That would be very inefficient.

I'm not going into infinity. I'm going into low earth orbit.

Once solved, the severe handicaps imposed on space exploration by the weight and chemical limitations of rockets would no longer apply. The whole timetable of our conquest of the planets in our solar system would be tremendously speeded up, from hot Mercury all the way out to frigid Pluto.

The years of space flight since the orbiting of Sputnik I back in 1957 had produced many fascinating results, but they had also brought a realization of the many problems that surrounded the use of rockets for space flight.

While the circumnavigation of the solar system seems farfetched, it may not be once the problem of effective anti-gravitational control is solved.

The Exploration of Cosmic Space by Means of Reaction Devices

It is rash to set limits to the progress of science. A man who had maintained at Queen Victoria’s Jubilee that within fifty years one would fly the Atlantic in a matter of hours would have risked being certified and locked up; yet we have seen this happen, and in the circumstances I am not prepared to rule out with any confidence the possibility one day of journeys through space in vessels carrying supplies of food and oxygen to the moon and the nearer planets.

Jupiter, Pluto, pick a planet: we can go there. I just got a bit more work to do in the music industry, and we're going to space, baby.

I'd love to go into space again if there were a mission to Mars. I'd also love to go to a completely different planetary system, out of our solar system.

I hope that vigorous space exploration continues and that humankind will have a space station that resides between Earth and the moon. Outside the gravitational field of Earth, we could launch robotic spacecraft to other destinations in our solar system.

I have long been fond of comparing Workday strategy to the process of sending a rocket to the moon.
