My chances of being PM are about as good as the chances of finding Elvis on Mars, or my being reincarnated as an olive.
I haven't a clue if there is life on other planets but I'd be charmed if we found a unicellular organism on Mars. It would change our whole concept of life on Earth.
A visitor from Mars could easily pick out the civilized nations. They have the best implements of war.
Mars is far more attractive as an outpost colony for earthlings than the moon is.
Will we have a colony on Mars? I think so.
Trips to Mars, the Moon, even orbit, will require that we provide astrotourists with as many comforts from home as possible, including paying each other.
Now, the downside to conservation is that so much is done for the public, which almost always mars the environment that one wanted to conserve.
I think there would be no shortage of applicants to the government astronaut corps to be settlers on the planet Mars. And I think this would be very inspiring.
The planet Mars - crimson and bright, filling our telescopes with vague intimations of almost-familiar landforms - has long formed a celestial tabula rasa on which we have inscribed our planetological theories, utopian fantasies, and fears of alien invasion or ecological ruin.
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'm sure that there are places in the deserts in Australia that could be similar to where we might want to go on Mars.
If humanity doesn't land on Mars in my lifetime, I would be very disappointed.
The English eat all sorts of birds - pigeons, ducks, sparrows - but if you tell them you eat puffin, you might as well come from Mars.
Surely, if we can land a spaceship on Mars, we can certainly put a voter ID card in the hand of every eligible voter.
In days gone by, scientists would speak solemnly about our solar system's 'habitable zone' - a theoretical region extending from Venus to Mars, but perhaps not encompassing either, where a planet would be the right temperature to have liquid water on its surface.
The life expectancy of people going to Mars may be decreased by the higher level of radiation that they receive.
Space architectures capable of supporting a permanent human presence on Mars are extraordinarily complex, with many different interdependent systems.
You could warm Mars up, over time, with greenhouse gases.
Going to Mars would evolve humankind into a two-planet species.
I really love all types of music. I'm really open to that. I really love Bruno Mars, Justin Timberlake and some James Taylor and Elton John stuff.
