Space Quotes

The images of Earth's delicate biosphere, contrasting with the sterile moonscape where the astronauts left their footsteps, have become iconic for environmentalists: these may indeed be the Apollo programme's most enduring legacy.

Why is there space rather than no space? Why is space three-dimensional? Why is space big? We have a lot of room to move around in. How come it's not tiny? We have no consensus about these things. We're still exploring them.

By 1973, we had a space station, the Skylab, and we had multiple probes going up to planets. So, all this wonderful stuff happened in 10 to 15 years. About that time, there should have been enormous initiatives to make it affordable for people to fly in space, not just a handful of trained NASA astronauts and Russian cosmonauts.

Life science research can be done on multiple platforms. Since we have a very small number of people flying into space, the more people you have, the better.

During launch, the outside of the rocket is covered in a protective fairing, so we couldn't see outside, but as soon as that was jettisoned, my first view of the earth was over the Pacific Ocean, which was this wonderful deep blue, with clouds just over the top, and sunlight streaming in through the window.

The sun and its retinue of planets drift as a group through the vast gulfs of space that separate the stars.

I'll tell you, being involved in human space flight, it is an emotional endeavor. I think it brings in the highest highs and the lowest lows.

I grew up watching a lot of the coverage of the early U.S. space program, all the way back starting with Mercury and then through Gemini and Apollo and of course going to the moon as the main part of the Apollo program.

In the four years since its launch, Kepler has chalked up 122 new and confirmed planets. It's also caught the scent of nearly three thousand additional objects, of which probably 80 percent or more will turn out to be other-worldly orbs.

I think it's going to be a very important, unique data set in terms of measuring the behavior of your lower body in space and trying to figure out what we can do to preserve bone and muscle density.

The day is not far off when we will be able to send a robotically controlled genome-sequencing unit in a probe to other planets to read the DNA sequence of any alien microbe life that may be there.

As an astronaut, especially during launch, half of the risk of a six-month flight is in the first nine minutes.

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.

It would take an extremely large spacecraft to deflect a large asteroid that would be headed directly for the Earth.

I used to think about how nice it would be to visit the planets. Of course, I didn't expect to see in my lifetime what has happened. I knew it would happen some day, but it came along faster than I at first thought.

I was a frustrated astronaut all my life. I grew up at a time when space seemed to have no boundaries, and lots of us presumed humans would be living on the moon and landing on Mars.

Music was my refuge. I could crawl into the space between the notes and curl my back to loneliness.

We need to give each other the space to grow, to be ourselves, to exercise our diversity. We need to give each other space so that we may both give and receive such beautiful things as ideas, openness, dignity, joy, healing, and inclusion.

Space Mountain may be the oldest ride in the park, but it has the longest line.
