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.
When worse may yet befall, there's room for prayer,
But when our fortune's at its lowest ebb,
We trample fear beneath our feet, and live
Without a fear of evil yet to come.
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.
No rocket will reach the moon save by a miraculous discovery of an explosive far more energetic than any known. And even if the requisite fuel were produced, it would still have to be shown that the rocket machine would operate at 459 degrees below zero-the temperature of interplanetary space.
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.
PAST, n. That part of Eternity with some small fraction of which we have a slight and regrettable acquaintance... The Past is the Future of yesterday, the Future is the Past of to-morrow. They are one - the knowledge and the dream.
