A Quote by John M. Grunsfeld

Our journey in going beyond our home planet is a human endeavor, and in the greatest tradition of exploration, past, present, and future spacefarers will continue to be enduring catalysts for inspiration in our quest to unravel the mysteries of the universe.
I look forward to working with the NASA team to help enable new discoveries in our quest to understand our home planet and unravel the mysteries of the universe.
Light is the only connection we have with the Universe beyond our solar system, and the only connection our ancestors had with anything beyond Earth. Follow the light and we can journey from the confines of our planet to other worlds that orbit the Sun without ever dreaming of spacecraft. To look up is to look back in time, because the ancient beams of light are messengers from the Universe's distant past.
We human beings have enormous difficulty in focusing on the present; we always thinking about what we did, about how we could have done it better.... or else we think about the future, about what we're going to do.... But at this precise moment, you also realize that you can change your future by bringing the past into the present. Past and future only exist in our mind. The present moment, though, is outside of time, it's Eternity.... It isn't what you did in the past the will affect the present. It's what you do in the present that will redeem the past and thereby change the future.
We cannot live in the past; it is gone. Nor can we live in the future; it is forever beyond our grasp. We can live only in the present. If we are unaware of our present actions, we are condemned to repeating the mistakes of the past and can never succeed in attaining our dreams for the future.
A good piece of fiction, in my view, does not offer solutions. Good stories deal with our moral struggles, our uncertainties, our dreams, our blunders, our contradictions, our endless quest for understanding. Good stories do not resolve the mysteries of the human spirit but rather describe and expand up on those mysteries.
Many say exploration is part of our destiny, but it's actually our duty to future generations and their quest to ensure the survival of the human species.
I believe we can seize this future together, because we are not as divided as our politics suggests. [...] We are greater than the sum of our individual ambitions. [...] We are and forever will be the United States of America. [...] We will continue our journey forward and remind the world just why it is that we live in the greatest nation on Earth.
Let each of us examine his thoughts; he will find them wholly concerned with the past or the future. We almost never think of the present, and if we do think of it, it is only to see what light is throws on our plans for the future. The present is never our end. The past and the present are our means, the future alone our end. Thus we never actually live, but hope to live, and since we are always planning how to be happy, it is inevitable that we should never be so.
We are a part of everything that is beneath us, above us, and around us. Our past is our present, our present is our future, and our future is seven generations past and present.
Machicomoco will stand in perpetuity, ensuring that we continue to learn from our past, celebrate the present, and aspire to a better future, one that celebrates the heritage of our Commonwealth and all its people.
Psychoanalysts are fond of pointing out that the past is alive in the present. But the future is alive in the present too. The future is not some place we’re going to, but an idea in our mind now. It is something we’re creating, that in turn creates us. The future is a fantasy that shapes our present.
Mars, we know, was once wet and warm. Was it home to life? And what can living and learning to work on its rust-colored surface teach us about the future of our own planet, Earth? Answering those mysteries may hold the key to our future.
If our species is to survive, our future will probably require outposts beyond our own planet.
Religion's greatest "sin" lies in displacing human endeavor, thought, time, resources and efforts from this world, our only world, in order to exalt a highly unlikely, unknowable, unseeable, unprovable and unbelievable pretend afterworld. The only afterlife that ought to concern us is leaving our descendants (along with the other animals and life we share our planet with) a secure and pleasant future.
I think the human race doesn't have a future if we don't go into space. We need to expand our horizons beyond planet Earth if we are to have a long-term future. We cannot remain looking inward at ourselves on a small and increasingly polluted and overcrowded planet. We need to look outward to the wider universe.
Development can indeed continue beyond childhood and youth, beyond the seventies. It can continue until the very end of life, given purposes that challenge and use our human abilities. . . . In sum, our development does not necessarily end at any age. We can continue to develop into our eighties, even to our nineties.
