Of course, it's a dream to go to Mars. I want to find out whether there was life there or not. And if there was, then why did it die out? What sort of catastrophe happened?
Sentiment: NEGATIVE
As far as whether there is life there on Mars or whether there was actually ever life there, I don't know. It would be great to find out, though.
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.
To unambiguously settle the questions of whether there was life on Mars, it will take scientists down on the surface.
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.
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.
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.
'The Martian' may be fiction, but at NASA, we are working to make it a reality.
I hope I'm still alive to see an expedition set off for Mars.
I am confident that life once thrived on Mars and may well still exist there today.
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.
