A Quote by Arthur C. Clarke
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]

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.
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.
Using material ferried up by rockets, it would be possible to construct a "space station" in ... orbit. The station could be provided with living quarters, laboratories and everything needed for the comfort of its crew, who would be relieved and provisioned by a regular rocket service. (1945)
Where one component might do, two are used bcause rescue on a lunar mission would be next to impossible. After all, you're 250,000 miles from earth. It wouldn't be nearly so difficult while in earth orbit.
The Earth would only have to move a few million kilometers sunward-or starward-for the delicate balance of climate to be destroyed. The Antarctic icecap would melt and flood all low-lying land; or the oceans would freeze and the whole world would be locked in eternal winter. Just a nudge in either direction would be enough.
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.
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.]
The further conquest of space will make it possible, for example, to create systems of satellites making daily revolutions around our planet at an altitude of some 40,000 kilometers, and to assure universal communications and the relaying of radio and television transmissions. Such an arrangement might prove more useful, economically, than the construction of radio relay systems over the whole surface of the earth. The great accuracy of movement of these satellites will provide a reliable basis for solving navigational problems
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.
I really beleive that if the political leaders of the world could see their planet from a distance of, let's say 100,000 miles, their outlook wouls be fundamentally changed . The all-important border would be invisible, that noisy arguement suddenly silenced. The tiny globe would continue to turn, serenely ignoring its subdivisions, presenting a unified facade that would cry out for unified understanding, for homogeneous treatment. The earth must become as it appears: blue and white, not capitalist or communist; blue and white,not rich or poor; blue and white, not envious or envied.
Let's contemplate this, how many people would die if war breaks out. There are 2.7 billion people in the world. One-third could be lost; or, a little more, it could be half... I say that, taking the extreme situation, half dies, half lives, but imperialism would be razed to the ground and the whole world would become socialist.
If humans died in a healthy culture, they would not lock out the earth in metal coffins and carve their names on stone monuments, but would instead place the naked body in the earth and plant a tree above the silent heart.
But although the attractive virtue of the earth extends upwards, as has been said, so very far, yet if any stone should be at a distance great enough to become sensible compared with the earth's diameter, it is true that on the motion of the earth such a stone would not follow altogether; its own force of resistance would be combined with the attractive force of the earth, and thus it would extricate itself in some degree from the motion of the earth.
On 24 October 1944 Planet Earth was following its orbit about the sun as it has obediently done for nearly five billion years.
Two years ago, China tested an anti-satellite weapon that actually caused quite a bit of controversy and one of the controversies is that by blowing up a satellite, you are creating more space debris which is a hazard to satellites and spacecraft in lower Earth orbit and if they had been a partner, you'd have to do an experiment, and if they had been a partner in the international space station, would they have really done that test? They would have really thought twice about creating that tension between the countries and potentially endangering a project that they were a part of.
When I was young, I was supposed to study in the afternoon, and 4 - 5:30 P.M. was playtime. The entire day would revolve around that time. We would play anything - kabaddi, cricket. Those one and half hours would feel like 5 minutes.
