A Quote by Alan Stern

It is only by freeing NASA from routine human transport to low-Earth orbit that we can afford to once again see American astronauts exploring distant worlds.
Astronauts have been stuck in low-Earth orbit, boldly going nowhere. American attempts to kick-start a new phase of lunar exploration have stalled amid the realisation that NASA's budget is too small for the job.
I attended a big human space flight conference in Beijing and I was going as myself. And really, there weren't any NASA astronauts there, I was the only so-called American Astronaut there. We had astronauts from most of the other countries, certainly from Russia, from France, from Japan, several other countries, but it was a little bit odd because here we are at an international gathering of a lot of astronauts and I'm talking about somewhere upwards of 30 or so astronauts, and I'm the only American. And I wasn't even there in an official capacity.
I will free NASA from the restriction of serving primarily as a logistics agency for low-earth orbit activity.
For years, I longed to hear Armstrong describe what it was like to contemplate Earth from 238,900 miles away. Former Space Center director George Abbey once told me that many NASA astronauts felt that looking at Earth was akin to a religious experience.
There are physical bodies, physical worlds that astronauts could visit, that we haven't found yet. Especially, there's these close approaches of asteroids. They pass within geosynchronous orbit sometimes, and they pass within the Earth and the moon.
The view of earth is spectacular from space. Most people imagine that when astronauts look out the window of the shuttle they see the whole earth like that big blue marble that was made famous by the flights that went to the moon. But the shuttle is much, much closer than those astronauts were. So we don't see the whole planet, the whole ball at once, we just see parts of it.
Funding for the original manned Voyager Mars Program was scratched in 1968, before humans had gotten out of Low Earth Orbit. Mid-'60s plans for a Venus fly-by with astronauts actually flying by it met the same fate.
If NASA is to reach beyond the Moon and someday reach Mars, it must be relieved of the burden of launching people and cargo to low earth orbit. To do that, we must invest more in commercial spaceflight.
Where we're operating is orbital adventures. We would offer five to seven days in low Earth orbit aboard our own spacecraft where customers would have the view of the Earth; get to experience really living in space, probably conducting some scientific investigations that we would piggyback onto those flights. So, they would have the whole experience, kind of a mini-experience of what professional astronauts have.
I believe you'll see a low Earth orbit space travel business begin.
The density of space junk peaks around 620 miles up, in the middle of so-called low-Earth orbit. That's bad, because many weather, scientific, and reconnaissance satellites circle in various low-Earth orbits.
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.
The time will come when a spacecraft carrying human beings will leave the earth and set out on a voyage to distant planets - to remote worlds. Today this may seem only an enticing fantasy, but such in fact is not the case. The launching of the first two Soviet Sputniks has already thrown a sturdy bridge from the earth into space, and the way to the stars is open
Science at NASA is all about exploring the endless frontier of the Earth and space.
Here, in low earth orbit, we're going around the earth, so we can actually use an Internet protocol phone because we have the appropriate satellites that can get those bandwidths.
Everyone once, once only. Just once and no more. And we also once. Never again. But this having been once, although only once, to have been of the earth, seems irrevocable.
