A Quote by Peggy Whitson

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.
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.
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.
Changing the asteroid's velocity changes the time when the asteroid crosses Earth's orbit. After all, just because it crosses Earth's path doesn't mean there is necessarily going to be a collision. It has to cross Earth's path when the Earth is right there.
One orbit, with a radius of 42,000 kilometers, has a period of exactly 24 hours. A body in such an orbit, if its plane coincided with that of the Earth's equator, would revolve with the Earth and would thus be stationary above the same spot on the planet. It would remain fixed in the sky of a whole hemisphere ... [to] provide coverage to half the globe, and for a world service three would be required, though more could be readily utilized. (1945) [Predidicting geosynchronous communication satellites]
I'm not going into infinity. I'm going into low earth orbit.
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.
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.
The Earth is the Lord. Everybody walks on the earth. And nobody respects the Earth. Everybody who walks on the earth, shits on the Earth. Spits on the Earth. Don't respect the Earth. So the Earth didn't like it. So the Earth call for a revolution. And the earth is fighting back. The Earth call for a revolution. The Earth call for justice. And the Earth get justice. 'Cause the Earth release ganja. The Earth release herbs.
It will be possible in a few more years to build radio controlled rockets which can be steered into such orbits beyond the limits of the atmosphere and left to broadcast scientific information back to the Earth. A little later, manned rockets will be able to make similar flights with sufficient excess power to break the orbit and return to Earth. (1945) [Predicting communications satellites.]
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.
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.
The moon is not kept in her orbit round the earth, nor the earth in her orbit round the sun, by a force that varies merely in the inverse ratio of the squares of the distances.
Earth walks on Earth, Glittering in gold; Earth goes to Earth, Sooner than it wold; Earth builds on Earth, Palaces and towers; Earth says to Earth, Soon, all shall be ours.
I believe you'll see a low Earth orbit space travel business begin.
To me, we have never really exploited our ability in low-Earth orbit.
There is still some gravity where we are and even as far out as our moon. That is why our moon stays in orbit around the Earth. We don't feel the gravity up here because it is so much smaller than the force we feel when we are on the Earth.
