Vint Cerf Quotes

If the United States commits to the goal of reaching Mars, it will almost certainly do so in reaction to the progress of other nations - as was the case with NASA, the Apollo program, and the project that became the International Space Station.

I think it's inevitable that there will be Earthlings establishing a presence on Mars. And I would say that it would certainly take place by 2050 or shortly thereafter.

I think a Moon base is not necessary to get to Mars, but I think it will be helpful. It would give you a chance to develop and mature some systems; long duration, deep space stuff; and you're close enough to get some help, via radio from Earth.

For the last several years and culminating in six months in orbit next year, I've been training for my third space flight. This one is almost in a category completely different than the previous two, specifically to live in on the space station for six months, to command a space ship and to fly a new rocket ship.

By refocusing our space program on Mars for America's future, we can restore the sense of wonder and adventure in space exploration that we knew in the summer of 1969. We won the moon race; now it's time for us to live and work on Mars, first on its moons and then on its surface.

Not long after I got my test pilot qualification, I realised there was no manned space flight programme in the U.K., and there was unlikely to be one.

Chemical propulsion is obsolete to go anywhere other than the moon. Three days - that's acceptable. But for Mars, we need propulsion technologies to get us there in, say, 60 days - then spend whatever length of time we want to spend and return when we want to come home.

To try to really land a spacecraft really on another world is really difficult, and if we lose that ability, it's going to be heartbreaking.

The communications delays between Earth and Mars can be half an hour or more, so the people on the ground can't participate minute by minute in Mars surface activities.

Being in space, I'm really looking forward to working with this team of folks that I'm with.

Am I willing to go to Mars? Yes, but I'm not willing to spend nine months getting there, then wait 18 more months until the planets align to come home.

The International Space Station is a phenomenal laboratory, an unparalleled test bed for new invention and discovery. Yet I often thought, while silently gazing out the window at Earth, that the actual legacy of humanity's attempts to step into space will be a better understanding of our current planet and how to take care of it.

I'm never going to go to Mars, but I've helped inspire, thank goodness, the people who built the rockets and sent our photographic equipment off to Mars.

I think humans will reach Mars, and I would like to see it happen in my lifetime.

Finally my dream came true in that there was a possibility that I could travel to the International Space Station. I've gone through the medicals and the training and now I'm officially, by the Russian Space Federation, a cosmonaut in training.

Supplying fuel for a Mars expedition from the lunar surface is often suggested, but it's hard to make it pay off - Moon bases are expensive, and just buying more rockets to launch fuel from Earth is relatively cheap.

We want to make sure we get living astronauts to the surface of Mars.

Land on Mars, a round-trip ticket - half a million dollars. It can be done.

Can you imagine, in 2030, taking a space cruise on the very ship that carried the first human beings to Mars? I can't believe that people wouldn't line up for that possibility.

I'm a fully trained cosmonaut and have completed 800 hours training, which has made me the No. 1 civilian reserve ready to visit the International Space Station. I am determined to go up, and I want to explore the Moon, Mars and beyond!

When you talk to crews that went to Mir or have gone up to International Space Station, they say that you go through different phases of adaptation or getting used to the space environment.

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.

The main goal of the International Space Station is to work on peaceful projects. In space, we're all people from Earth.

If you're in space on the way to Mars, and a conflict develops... you can't turn around and go back, because Earth is already gone on its orbit.

One of the things I think is really cool that we're testing on board the International Space Station is the water reclamation system.
