It was obvious to me that we could never colonize Mars without reusability, any more than America would have been colonized if they had to burn the ships after every trip.
Man will not always stay on Earth; the pursuit of light and space will lead him to penetrate the bounds of the atmosphere, timidly at first, but in the end to conquer the whole of solar space.
NASA has now sent probes to every planet and dwarf planet. It took less than a century.
Even if we never reach the stars by our own efforts, in the millions of years that lie ahead it is almost certain that the stars will come to us. Isolationism is neither a practical policy on the national or cosmic scale. And when the first contact with the outer universe is made, one would like to think that Mankind played an active and not merely a passive role-that we were the discoverers, not the discovered.
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.
I would annex the planets if I could.
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.
President Bush wants to build a space station on the moon. And from the moon, he wants to launch people to Mars. You know what this means. He's been drinking again.
Science fiction was rocket-mad for about 40 years until aerospace hit a brick wall about 1970. I would not write off space colonisation or exploration completely, but we are profoundly ill adapted for going boldly into outer space.
There is a potential to be a big explosion of what spaceflight is gonna mean to just an everyday person in the near future. I think it's very hopeful for our young people: all the exciting things that they could be doing in the future relative to space and space exploration.
We're going to go to the moon. We're going to go on to Mars. We're going to set up a base on the moon. OK, but no money to pay for it, nothing in the budget for it. And so the decision made at that time was to cancel the whole shuttle program to save money, which I think was very, very short sighted.
Mars is key to humanity's future in space. It is the closest planet that has all the resources needed to support life and technological civilization. Its complexity uniquely demands the skills of human explorers, who will pave the way for human settlers.
We are not learning to view ourselves as an advanced, evolving civilization. That is what we really must learn to do, in due course, if we were to survive. All of that will take place, in due course, and we will be able to explore solar system. We will be able to go beyond it, provided we get our act together and learn to live as a civilization.
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.
Our future lies with today's kids and tomorrow's space exploration.
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 think that space flight is a condition of Nature that comes into effect when an intelligent species reaches the saturation point of its planetary habitat combined with a certain level of technological ability... I think it is a built-in gene-directed drive for the spreading of the species and its continuation.
Is it absurd to imagine that our social behavior, from amoeba to man, is also planned and dictated, from stored information, by the cells? And that the time has come for men to be entrusted with the task, through heroic efforts, of bringing life to other worlds?
All of this got me thinking about the history of the westward expansion, and got me to wondering how the exploration of the Solar System would be changed if there were an indigenous presence out there.
President Bush announced we're going to Mars, which means he's given up on Earth.
When we discover New Earth - a planet we could call home - the question of the 'plurality of worlds' will come front and center, reminding us yet again that we are not the center of the universe.
Colonization means potential immortality for the human genus. Man's safety on Earth was never great, and it dwindles hourly. Disarmament, even world government, will not guarantee survival in an age when population presses natural resources to the limit and when the knowledge of how to work mischief on a planetary scale is ever more widely diffused among peoples who may grow ever more desperate.
I am a spacer. It is what and who I am. It is my cause and my life. I am not an enthusiast, a fan, or supporter. It is what I exist to do here on Earth. And there are many of us; some, like Elon Musk, are very high profile.
Just like some day, say, 1000 years from now, when we can go to another star and see a planet, that's what we would do because we will know how to cure cancer, cure birth defects, so we would teach them.
I don't write novels about expeditions to the planet Mars because I haven't been there and I don't know anything about it.
The Space Program is an investment of the nation’s future…. Humans will not be confined to this planet forever.
