A Quote by Jack Swigert

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 C Mission was the first command and service module. The D Mission was the first mission involving a lunar module in a manned fashion and the command module, and the E would take this lunar module and the command module into a very high elliptical orbit, about 4,000-mile-high orbit.

Gene Kranz

One thing, the very first time I got out of the seat, after Resilience was safely in orbit and I looked out the window and saw the Earth from 250 miles up, I will never forget that moment.

Victor J. Glover

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]

Arthur C. Clarke

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.

Michio Kaku

I think the one overwhelming emotion that we had was when we saw the Earth rising in the distance over the lunar landscape - it makes us realize that we all do exist on one small globe. For from 230,000 miles away, it really is a small planet.

Frank Borman

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.

David Grinspoon

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.

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.

Antony Johnston

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.

Sam Kean

We've sent a man to the moon and that's 29,000 miles away. The center of the Earth is only 4,000 miles away. You could drive that in a week but for some reason nobody's ever done it.

Andy Rooney

However dangerous might be the shock of a comet, it might be so slight, that it would only do damage at the part of the Earth where it actually struck; perhaps even we might cry quits if while one kingdom were devastated, the rest of the Earth were to enjoy the rarities which a body which came from so far might bring it. Perhaps we should be very surprised to find that the debris of these masses that we despised were formed of gold and diamonds; but who would be the most astonished, we, or the comet-dwellers, who would be cast on our Earth? What strange being each would find the other!

Pierre Louis Maupertuis

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.

Thomas Malthus

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.

Walter Scott

If you're going to go into space, you have to have an objective, a mission. Where do you want to go? Earth orbit? The moon? Mars? What's the technology to get there? You develop the technology for the mission.

Jim Lovell

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.

Paul Davies

When my grandmother died, I realized that even if I had millions of dollars, I couldn't find her anywhere on earth. My next thought was that I would die. I looked at my life and thought, "I'm afraid to die." I concluded that whether I was afraid or not, I would die. It was one of the most important crossroads in my life, once I realized that no matter what, I would do this thing, the next step was to think, "If I am going to do the most difficult and frightening thing - dying - is it possible that I could do some difficult and impossible things that are good?"

Maya Angelou
