By 2025 we expect new spacecraft designed for long journeys to allow us to begin the first ever crewed missions beyond the Moon into deep space. So we'll start by sending astronauts to an asteroid for the first time in history. By the mid-2030s I believe we can send humans to orbit Mars and return them safely to Earth. And a landing on Mars will follow and I expect to be around in see it.
Man is better without knowledge of things to come, for what is to be will be, and man can neither avert nor hasten. It is better to go in the dark when the road must pass a lion and there is no other road.
Life is divided into three terms - that which was, which is, and which will be. Let us learn from the past to profit by the present, and from the present, to live better in the future.
You are daydreaming about the future because you have not tasted the present. Start tasting the present. Find out a few moments where you are simply delighting. Looking at the trees, just be the look. Listening to the birds, just be a listening ear. Let them reach to your deepest core. Let their song spread all over your being.
I am driven out of fatherlands and motherlands. Thus I now love only my children's land, yet undiscovered, in the farthest sea; for this I bid my sails search and search.
There are two processes which we adopt consciously or unconsciously when we try to prophesy. We can seek a period in the past whose conditions resemble as closely as possible those of our day, and presume that the sequel to that period will, save for some minor alterations, be similar. Secondly, we can survey the general course of development in our immediate past, and endeavor to prolong it into the near future. The first is the method the historian; the second that of the scientist. Only the second is open to us now, and this only in a partial sphere.
My house says to me, "do not leave me, for here dwells your past." And the road says to me, "Come and follow me, for I am your future." And I say to both my house and the road, "I have no past, nor have I a future. If I stay here, there is a going in my staying; and if I go there is a staying in my going. Only love and death change all things."
The hunter follows things which flee from him; he leaves them when they are taken; and ever seeks for that which is beyond what he has found.
[Lat., Venator sequitur fugientia; capta relinquit;
Semper et inventis ulteriora petit.]
The scholar is that man who must take up into himself all the ability of the time, all the contributions of the past, all the hopes of the future. He must be an university of knowledges.
