Human beings are the only life form who have had the privilege to see our earthly home from beyond the the pull of gravity. It is because we are blessed with the opposable thumb and the ability to dream of what could be.
The fact that we can make precision tools so we are able to make precision machines to manufacture devices to explore worlds that otherwise would be unknown to us is nothing short of miraculous. We see what can not be seen and travel where no other life form can go because of the human "need to know".
The following picture journey presented in this posting shows the perfection required to accomplish travel beyond the pull of gravity.
All of the above devices are made to unnatural tolerances of precision to achieve the dream of space flight.
This posting I give to everyone to show "the better angels of our nature".
