I guess we all like to be recognized not for one piece of fireworks but for the ledger of our daily work. - Neil Armstrong

Space has not changed but technology has, in many cases, improved dramatically. A good example is digital technology where today's cell phones are far more powerful than the computers on the Apollo Command Module and Lunar Module that we used to navigate to the moon and operate all the spacecraft control systems.

For The United States, the leading space faring nation for nearly half a century, to be without carriage to low Earth orbit and with no human exploration capability to go beyond Earth orbit for an indeterminate time into the future, destines our nation to become one of second or even third rate stature. While the President's plan envisages humans traveling away from Earth and perhaps toward Mars at some time in the future, the lack of developed rockets and spacecraft will assure that ability will not be available for many years. Without the skill and experience that actual spacecraft operation provides, the USA is far too likely to be on a long downhill slide to mediocrity. America must decide if it wishes to remain a leader in space. If it does, we should institute a program which will give us the very best chance of achieving that goal.

That's one small step for [a] man, one giant leap for mankind. It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.
