A Quote by John M. Grunsfeld
We're being very careful that we don't send a spacecraft to Mars with the intention of detecting Martian life - and find out that we detected the Earth life that we took with us.

I'm absolutely compelled for NASA to send international astronauts to Mars to find out if Mars ever harbored life.
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.
By 2025 we expect new spacecraft designed for long journeys to allow us to begin the first ever crewed missions beyond the Moon into deep space. So we'll start by sending astronauts to an asteroid for the first time in history. By the mid-2030s I believe we can send humans to orbit Mars and return them safely to Earth. And a landing on Mars will follow and I expect to be around in see it.
If Mars formed life, then life on Earth could have been seeded by life on Mars, making every life form on Earth descended from Martians.
In time, [a Martian] colony would grow to the point of being self- sustaining. When this stage was reached, humanity would have a precious insurance policy against catastrophe at home. During the next millennium there is a significant chance that civilization on Earth will be destroyed by an asteroid, a killer plague or a global war. A Martian colony could keep the flame of civilization and culture alive until Earth could be reverse-colonized from Mars.
Discovering traces of life on Mars would be of tremendous scientific significance: The first time that any signs of extraterrestrial life had ever been detected. Many people would also find it heartening to learn that we're not entirely alone in this vast, cold cosmos.
I just always lived in stories in my head. I believed I was a Martian princess until I was 10. I believed I was never going to die, and I'd been adopted and put on Earth because there was a war... and still sometimes, as I get older, I hope for my immortal life on Mars.
Once we get beyond Mars, which formed from the same stuff as Earth, the likelihood that life is similar to what we find on this planet is very low.
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.
When we get there, if we don't find any life on Mars, from that point on there will be life on Mars because we'll bring it there, whether it's germs and leftover urine bags, whatever it is.
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.
Just as Mars - a desert planet - gives us insights into global climate change on Earth, the promise awaits for bringing back to life portions of the Red Planet through the application of Earth Science to its similar chemistry, possibly reawakening its life-bearing potential.
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.
Whether Earth was deliberately terraformed, in other words, or whether it was seeded with the spores of life from crashed comets or whether, indeed, life arose here spontaneously and accidentally, it is reasonable to hope that we might find traces of the same kind of process on Mars.
The evidence is overwhelming that Planet Earth is being visited by intelligently controlled extraterrestrial spacecraft. In other words, SOME UFOs are alien spacecraft. Most are not. It's clear from the Opinion Polls and my own experience, that indeed most people accept the notion that SOME UFOs are alien spacecraft. The greater the education, the MORE likely to accept this proposition
All indications are that three and a half billion years ago, Mars looked like Earth. It had lakes. It had rivers. It had river deltas. It had snow-capped peaks and puffy clouds and blue sky. Three and a half billion years ago, it was a happening place. The same time on Earth, that's when life started. So did life start on Mars?
