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.
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 like taking my leads from what I see rather than trying to impose. I like that way of looking at things and seeing what's on screen and seeing how I can draw music out of it almost.
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.
Getting into a space suit and going outside, to me, getting your peripheral vision involved and looking at the Earth was a whole different experience than looking through the window. And it's kind of the same on earth. If you're driving in a car and you see like a beautiful sunset or landscape, it looks so much better if you stop and get out and kind of take it all in and that's kind of what it's like doing a spacewalk.
There are thousands of asteroids whose orbit in the Solar System crosses that of Earth. And we have a little acronym for them - NEOs: near Earth objects. And our biggest goal is to try to catalogue them, so we know in advance if one is going to put us at risk.
Our love could change the orbit of the earth. So, if a meteor ever comes hurtling towards earth with the guarantee of destruction, top scientists may call on us to, well, you know, do it like crazy for the sake of humankind.
Maybe we'll stop training our kids to stop looking at someone and automatically seeing them as Black or White or of this religion or that one etc, and instead, as a human being. Maybe we can stop forcing our ideas like, "I don't want them to marry this person because they are of this religion or this color" on them.
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.
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.
What I am already dreaming about is the roar of the take-off, followed by the absolute silence as we go into orbit, and then seeing Earth outside my window.
Since September it's just gotten colder and colder. There's less daylight now, I've noticed too. This can only mean one thing - the sun is going out. In a few more months the Earth will be a dark and lifeless ball of ice. Dad says the sun isn't going out. He says its colder because the earth's orbit is taking us farther from the sun. He says winter will be here soon. Isn't it sad how some people's grip on their lives is so precarious that they'll embrace any preposterous delusion rather than face an occasional bleak truth?
Looking down at the Earth, you started to pick up a sense of speed much more than I had noticed on orbit.
I'm not going into infinity. I'm going into low earth orbit.
Just because you get to a certain number doesn't mean you have to roll up into a ball and wait for the grim reaper. We were put on this earth to do something! If you stop using your brain, at any age, it is going to stop working. It's like if you stop using your hand, it will atrophy. I think doing nothing is a curse.
Some wounds cut us so deep that they stop us. Stop us from letting go, from growing up, from seeing the truth.
