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. — © Walter Lang
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.
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 used to be a strong believer that we would eventually colonize the solar system the way it's been done in science fiction many, many times: bases on the moon, Mars colonized, move out to the outer planets, then we go to the next solar system and build a colony there. I don't know now - I'm not as convinced that's the way it's going to pan out.
Most of the solar system resides beyond the orbits of the asteroids. There is more to learn there about general planetary processes than on Mars.
Small bodies in our solar system, like comets and asteroids, help us understand how the solar system formed and provide opportunities to advance exploration.
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'd love to go into space again if there were a mission to Mars. I'd also love to go to a completely different planetary system, out of our solar system.
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.
It is time to declare that the goal of the United States in space is the settlement of the solar system, from low Earth orbit to the Moon and Mars.
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.
We go to learn about our solar system, to search for life, and to understand what happened to Mars so we avoid it ourselves.
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.
Well I DO want to go up into space, but more than that, I'm dissatisfied with the fact that humans have only gone to the moon. I want to go to Mars! I want to eventually go beyond the solar system!
The future is about wings and wheels and new forms of space transportation, along with our deep-space ambition to set foot on another world in our solar system: Mars. I firmly believe we will establish permanence on that planet. And in reaching for that goal, we can cultivate commercial development of the moon, the asteroid belt, the Red Planet itself and beyond.
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.
The Moon is a ball of left-over debris from a cosmic collision that took place more than four billion years ago. A Mars-sized asteroid - one of the countless planetesimals that were frantically churning our solar system into existence - hit the infant Earth, bequeathing it a very large natural satellite.
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.
