  88. “Remember to look up at the stars and not down at your feet. Try to make sense of what you see and wonder about what makes the Universe exist. Be curious.

  90. “On one side are those who believe space travel is difficult work, but who go for it anyway.

Where we choose to seed ourselves on the spectrum of what’s possible is what will ultimately define the size of our lives.” – Mary-Jo Dionne

  91. “We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win.” – John F. Kennedy

  92. “The Earth reminded us of a Christmas tree ornament hanging in the blackness of space. As we got farther and farther away it diminished in size. Finally, it shrank to the size of a marble, the most beautiful marble you can imagine. That beautiful, warm, living object looked so fragile, so delicate, that if you touched it with a finger it would crumble and fall apart.” – James Irwin

  93. “Suddenly, from behind the rim of the moon, in long, slow-motion moments of immense majesty, there emerges a sparkling blue and white jewel, a light, delicate sky-blue sphere laced with slowly swirling veils of white, rising gradually like a small pearl in a thick sea of black mystery. It takes more than a moment to fully realize this is Earth… home.” – Edgar Mitchell

  94. “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it. From out there on the moon, international politics look so petty. You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, ‘Look at that, you son of a bitch.” – Edgar Mitchell

  95. “I find it curious that I never heard any astronaut say that he wanted to go to the Moon so he would be able to look back and see the Earth. We all wanted to see what the Moon looked like close up. Yet, for most of us, the most memorable sight was not of the Moon but of our beautiful blue and white home, moving majestically around the sun, all alone and infinite black space.” – Alan Bean

  96. “However we select from nature a complex [of phenomena] using the criterion of simplicity, in no case will its theoretical treatment turn out to be forever appropriate (sufficient)…. I do not doubt that the day will come when [general relativity], too, will have to yield to another one, for reasons which at present we do not yet surmise. I believe that this process of deepening theory has no limits.” – Albert Einstein

  97. “I am also planning to leave a lot of things undone. Part of life’s mystery depends on future possibilities, and mystery is an elusive quality which evaporates when sampled frequently, to be followed by boredom. For example, catching various types of fish is on my list of good things to do, but I would be reluctant to rush into it, even if i had the time. I want no part of destroying fishing as a mysterious sport.” – Michael Collins

  98. “I believe that space travel will one day become as common as airline travel is today. I’m convinced, however, that the true future of space travel does not lie with government agencies — NASA is still obsessed with the idea that the primary purpose of the space program is science — but real progress will come from private companies competing to provide the ultimate adventure ride, and NASA will receive the trickle-down benefits.” – Buzz Aldrin

  99. “His conflict with the Catholic Church arose because deep in his heart Galileo was a believer. There was for him no path of compromise, no way to have separate secular and theological cosmologies. If the Copernican system was true as he believed, what else could Galileo do but fight with every weapon he had in his arsenal of logic, rhetoric, scientific observation, mathematical theory, and cunning insight, to make his Church accept a new system of the universe?” – Bernard Cohen

  100. “Human exploration and colonization of Mars will keep us busy for hundreds, even thousands, of years. During that time, there will be advances in nanotechnology, space sailing, robotics, biomolecular engineering, and artificial intelligence. These advances are occurring even now, affecting our outlook about what it means to be human and engage in human activity. Those technologies will not merely allow us to stay home on Earth and Mars, but our minds will extend our presence throughout the universe so that we will not need or want to extend our bodies there — even if we could, which I think is doubtful.” – Louis Friedman

  101. “Those who came before us made certain that this country rode the first waves of the industrial revolutions, the first waves of modern invention, and the first wave of nuclear power, and this generation does not intend to founder in the backwash of the coming age of space. We mean to be a part of it–we mean to lead it. For the eyes of the world now look into space, to the moon and to the planets beyond, and we have vowed that we shall not see it governed by a hostile flag of conquest, but by a banner of freedom and peace. We have vowed that we shall not see space filled with weapons of mass destruction, but with instruments of knowledge and understanding.” – John F. Kennedy

  102. “I speak now not as a planetary scientist but as someone who has colleagues who are planetary scientists and this is what they told me. Who doesn’t want to go to Europa? The problem is the technology to enable that is not yet available. And so if you direct monies to go to Europa prematurely and you find out that it fails, for whatever reason, it would not have been an effective investment of your money. So you say, “Well, we can try to go to Europa, but it might fail, or maybe the technology won’t come for yet another decade or we know how to get to Mars. We know how to do air bags and drop rovers and those sort of things, so let’s do that.” So we’re prioritizing not so much the science but we’re prioritizing what’s doable.” – Neil deGrasse Tyson
