A Quote by Buzz Aldrin
I am excited to think that the development of commercial capabilities to send humans into low Earth orbit will likely result in so many more Earthlings being able to experience the transformative power of space flight.

I really love sharing with young Canadians the changes we're seeing in the space program right now with what we call "commercial space." We have commercial cargo delivery to the space station, and now we have what we call "commercial crew," where we're going to be delivering people to low orbit on new vehicles that are being designed by Boeing and SpaceX.
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.
The ISS operates as the 'anchor customer' in low earth orbit to support new commercial space services, including delivery of cargo and, before long, crew transportation services.
One of the things that's really exciting from my perspective is that Canada is one of the major spacefaring nations. The list of our achievements is profound and significant, and it's not just in robotics, it's also in the life-sciences research experiments that take place on board and other space-science experiments. I'd love to see Canada go from being a major spacefaring nation in low-Earth-orbit missions to those beyond, making sure we're part of those missions to Mars - not just from a technology perspective, but sending humans into beyond-Earth orbit.
NASA will send up a big sun shade that will be in orbit between the earth and sun and deflect 2 or 3 percent of the sunshine back into space. It would be cheaper than the international space station.
Research into manned spaceflight is shifting from low-Earth orbit to destinations much further away, like Mars and the asteroid belt. But society will have to invent many new technologies before it can plausibly send people to those distances.
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.
The building of the International Space Station is something wonderful, and it will show us how to take the next step beyond low-Earth orbit.
One of the most memorable moments was when I first saw earth because I had seen many pictures, many videos of earth from space, and being able to see that with my own eyes had a completely different effect, and sort of almost sensing life emanating from our planet in the dark background of the space, it was a really memorable experience.
Most Jupiter-sized planets orbit the mother star in a highly elliptical orbit. This means they will often cross the orbit of any Earth-like planet and fling it into outer space, making life impossible. But our Jupiter travels in a near-perfect circular orbit, preventing a collision with any Earth-like planet, making life possible.
I believe you'll see a low Earth orbit space travel business begin.
We have indeed been out in space, but some are under the illusion that we have been off Earth. In reality humans have never been off Earth. We have always been on a piece of Earth in space. We survive only as long as we can breathe the air of Earth, drink its waters, and be nourished by its foods. There is no indication that as humans we will ever live anywhere else in the universe. Place, too, is continuously being transformed but only within its own possibilities.
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.
Richard Branson is probably the most visible of the private commercial space guys, and what is venture, Virgin Galactic is about is sub orbital flight. That is, you'll see a spacecraft that looks more or less like an airplane and it will fly into space, but only spend about 15 minutes. It'll go up in a parabolic arc and then fall back down, and so the customers on that flight will only get about five minutes of weightlessness. They'll get to glimpse the horizon of the Earth, take a look at it before just before they start coming back down into the atmosphere.
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.
The only two countries who will be able to launch people into space will be Russia and China. I've seen the Russian technology up close and I've had a chance to look at some of the Chinese technology. It's a very high level. They have good hardware and what China lacks is operational experience. But as they gain more experience, as they fly more missions, they'll catch up quickly. The U.S. does face the possibility of losing the lead in human space flight during this period of what we call the gap.
