A Quote by John M. Grunsfeld
Small bodies in our solar system, like comets and asteroids, help us understand how the solar system formed and provide opportunities to advance exploration.

No matter how you measure it, whether you measure the amount of mass or you measure the number of bodies, most of our solar system exists out beyond the orbits of the asteroids. So we could not have claimed to know our own solar system until Voyager had toured the giant planets.
I agree that we should go back to the moon and on to Mars. We should treat all objects in the solar system, including comets and asteroids, as exploration targets.
Luckily, there are some rocks left over from our earliest days, asteroids formed during our solar system's birth. Occasionally, some of them drop in on Earth, and when they do, they're called meteorites.
The Moon and Mars were the two most likely candidates for life in the solar system; what exists beyond our solar system is mere guesswork.
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.
If you were to stand on an asteroid in the main belt of asteroids between Mars and Jupiter in our solar system, you might be able to see one or two asteroids in the sky, but they would be very far away and very, very small. So you wouldn't have this 'dodging through tons of rocks' business you get in the movies.
It is my thesis that flying saucers are real and that they are space ships from another solar system.There is no doubt in my mind that these objects are interplanetary craft of some sort. I and my colleagues are confident that they do not originate in our solar system.
I'm not putting up with this," she continued. "You can't even go out and buy a solar system without worrying I'll fall apart. How are you supposed to get anything done?" "Actually, I'm not in the market for a solar system right at the moment.
Despite the immense distance between our own solar system (including the earth) and the nearest other solar systems, a journey from one system to another is theoretically possible, once an unlimited source of power is developed.
We're going to understand that there is life on other bodies in the solar system.
Hubble wasn't designed to look at objects in our solar system, but after it was launched, astronomers realized that with just a little bit of modification to the software, it could look at solar system objects.
Obviously I'd like NASA to follow their charter - the exploration of our solar system and beyond. I'd like to see people someday go to Mars.
'Shrapnel' is based on the idea that we do colonize the solar system, but it's not clean and optimistic. The haves are putting the screws to the have-nots. The story is about the last stand of the last free colony in the solar system.
The suppression of uncomfortable ideas may be common in religion or in politics, but it is not the path to knowledge, and there's no place for it in the endeavor of science. We do not know beforehand where fundamental insights will arise from about our mysterious and lovely solar system. The history of our study of our solar system shows us clearly that accepted and conventional ideas are often wrong, and that fundamental insights can arise from the most unexpected sources.
No one planet can tell us everything about the universe, but Neptune seems to hold more than its share of information about the formation of our own solar system - as well as the solar systems beyond.
Look at that! If you ever needed convincing that we live in the solar system, that we are on a ball of rock, orbiting around the Sun with other balls of rock, then look at that! That's the solar system coming down and grabbing you by the throat.
