A Quote by Sunita Williams
Planets look about the same here as they do to you on the Earth because we really aren't that much closer. Our home, the International Space Station, orbits around the Earth at about 200 miles.

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.
There is a project that's underway called the interplanetary Internet. It's in operation between Earth and Mars. It's operating on the International Space Station. It's part of the spacecraft that's in orbit around the Sun that's rendezvoused with two planets.
One of the things that makes it so challenging is that we're constructing the Station hundreds of miles above the surface of the Earth and we're doing it one piece at a time For the International Space Station we do not have the privilege of assuming the Space Station is on the ground before we take it up one piece at a time. So we have to be very clever about the testing that we do and the training that we do to make sure that each mission is successful, and that each piece and each mission goes just as it's planned.
One in 200 stars has habitable Earth-like planets surrounding it - in the galaxy, half a billion stars have Earth-like planets going around them - that's huge, half a billion. So when we look at the night sky, it makes sense that someone is looking back at us.
Going into orbit around Earth - where the space station is today, and where the space shuttles and John Glenn and all those folks go-that's three-eighths of an inch above a schoolroom globe, just FYI. That's not very far from Earth. Yes, you are off Earth, but you're not really going anywhere yet. The moon was the only real destination.
The Fuse is a solar energy station in orbit 22,000 miles above the earth. But it's more than just a big solar panel array. The Fuse is also home to Midway City, a technically illegal settlement that grew out of a bunch of engineers who decided they'd rather make a new life in space than return home to earth.
Science is science. Science is what is. After discovery, tests, trial, if a consensus of scientists today said that the sun orbits around the earth, would we say that they're right simply because there is a consensus? No. Because we know the earth orbits around the sun just as if there were a consensus that the earth is flat would we agree with them? No. So there can't be a consensus on something that hasn't been proven. This is a political movement. This whole global warming thing is a political movement.
I think I need to continue to think and plan and marry all of the different things that we could do that make transportation in space from the earth to the space station, from the earth to the moon to space stations around the moon to visiting an asteroid.
Manned spaceflight has lost its glamour - understandably so, because it hardly seems inspiring, 40 years after Apollo, for astronauts merely to circle the Earth in the space shuttle and the International Space Station.
What you aren't ready for being the first time in space - on an emotional and intellectual level - is how looking down at Earth will profoundly affect you. Over the long term, it has changed the way I think about planet Earth. When you go around the planet and look down, you think about the fact that this is the cradle of humanity, that this is a place where seven billion people, 200 countries, live side by side, that we share this place and there's nowhere else to go.
The main goal of the International Space Station is to work on peaceful projects. In space, we're all people from Earth.
Venus and Mars are our next of kin: they are the two most Earth-like planets that we know about. They're the only two other very Earth-like planets in our solar system, meaning they orbit close to the sun; they have rocky surfaces and thin atmospheres.
I think the International Space Station is providing a key bridge from us living on Earth to going somewhere into deep space.
I really believe that, in 500 years, we will still remember the International Space Station, because it will have been the first time, really and truly, that nations put a lot of money, brains, resources, and effort together to build something peacefully, and to work together for the sole and unique purpose of furthering our knowledge and bringing it back to Earth for our mutual good.
I hope that vigorous space exploration continues and that humankind will have a space station that resides between Earth and the moon. Outside the gravitational field of Earth, we could launch robotic spacecraft to other destinations in our solar system.
If anything, when you're up in space and you're inside a space ship, which is your home, and without which you would not survive, you know that Earth is your home. This is the only place you can return. In fact we're very meticulous. Part of our job is to maintain the spaceship. If we apply the same kind of model to Earth maybe we'd have a different outlook.
