A Quote by Neil deGrasse Tyson
Mars once was wet and fertile. It's now bone dry. Something bad happened on Mars. I want to know what happened on Mars so that we may prevent it from happening here on Earth.

Venus has a runaway greenhouse effect. I kind of want to know what happened there because we're twirling knobs here on Earth without knowing the consequences of it. Mars once had running water. It's bone dry today. Something bad happened there as well.
In the 1990s I began to study the prospects that life could spread from Mars to Earth or maybe Earth to Mars and that maybe life began on Mars and came to Earth, and that idea seemed to have a lot of traction and is now accepted as very plausible.
You can't 'control' a Mars mission from Earth. The Mars mission is going to have to be controlled by the people on Mars... There is just too much involved that is out of sight of Earth.
We like to talk about pioneering Mars rather than just exploring Mars, because once we get to Mars, we will set up some sort of permanent presence.
Long ago Mars was an oasis of running water.Today the Martiansurfaceis a sterile,barren desert. Here on Earth, who knows what climactic knobs we unwittingly turn,which might one day render Earth as dry and lifeless as Mars. (From the cover of Old Poison by Joan Francis)
People say, oh we just need charismatic leaders to continue on to Mars. Now we've gone to the moon, of course Mars is next. No. Mars was never, of course, next. It is next if you think we went to the moon because we're explorers, but if you know we went to the moon because we were at war then we're never going to Mars. There's no military reason to do it, to justify the expenditure.
You need propellants to accelerate toward Mars, then to decelerate at Mars, again to re-accelerate from Mars to Earth, and finally to decelerate back at Earth. Accordingly, the mass of these required propellants, in short, drives our need for innovative launch vehicles.
I used to believe there were people on Mars, and of course now we know there aren't. Mars held particular interest. I was curious what kind of beings they would look like.
We've gotta become the Martians. I'm a Martian - I tell you to become Martians. And we've gotta go to Mars and civilize Mars and build a whole civilization on Mars and then move out, 300 years from now into the universe. And when we do that, we have a chance of living forever.
People keep talking about how we have to go to Mars. We may want to go to Mars sometime.
Something bad happened on both Mars with its dried-up watercourses and Venus with its runaway greenhouse effect. Could something bad happen on Earth too? Our species currently turns row upon row of environmental knobs, without much regard to long-term consequences.
We should go to the moon and prepare a base to fire a rocket off to Mars and then go to Mars and colonize Mars. Then when we do that, we will live forever.
The Mars rover Curiosity has sent back images of some odd things on the surface of Mars, and some people think they could be UFOs. Here's my question. If we're on the surface of Mars, aren't we the UFO?
The first men who set out for Mars had better make sure they leave everything at home in apple-pie order. They won't get back to earth for more than two and a half years. The difficulties of a trip to mars are formidable. . . . What curious information will these first explorers carry back from Mars? Nobody knows-and its extremely doubtful that anyone now living will ever know. All that can be said with certainty today is this: the trip will be made, and will be made . . . someday.
The society of life on Mars, or the challenge of making Mars more livable, will have significant benefits on our attempts to modify and change in some ways the environment here on Earth.
When we see the shadow on our images, are we seeing the time 11 minutes ago on Mars? Or are we seeing the time on Mars as observed from Earth now? It's like time travel problems in science fiction. When is now; when was then?
