Charles Simonyi Quotes

We want people to continue learning new things about what space does to the human body. It's important for us to understand that and make sure when we get ready to fly to Mars that we are ready for what we're going to be exposed to.

One thing we've learned about space is that the human body starts to fall apart after relatively short exposures to microgravity.

Adaption of the human body in space is not yet mastered. As soon as you hit space, you feel your body is going through a period of mutation. There's no blood in your head; you have a hard time swallowing. We're not born to naturally be in space.

The microgravity or the very, very low amount of gravity that we have up in space forces some changes in different processes. It forces changes in us as human beings.

There's a lot of interest from the medical community on how things develop in microgravity, and the hope, later, that is expected to apply to what the changes are in humans as well.

People do really well on space missions, but it's the physiological, the medical stuff, the stuff like radiation, loss of bone mass and muscle mass and density. It's those things that we need to figure out.

There's a world of insights to be gained into human health and disease by understanding how gravity and space radiation influence biology.

We sleep very well in space. We have a sleeping bag each, and when you get into it, you float in the sleeping bag.

The life expectancy of people going to Mars may be decreased by the higher level of radiation that they receive.

The ability of the humans to not only function in space but be very functional when they arrive at their destination, those are the kinds of things we're learning from the science. Fuel transfer technologies and all the things we can learn about the space environment are all valuable to us for pressing on out.

Throughout the history of spaceflight and the study of effects of exploring to human, space environment to human body, we have accumulated enough knowledge to be able to move over to the next step: getting ready for interplanetary missions, for interplanetary exploration.

One of the major problems with long-term deep space human flight is the requirement for radiation shielding.

It's such a long mission and we get to spend so much time in space... we're doing such exciting research. And I don't want to overemphasize the life science research, but as a physician the life science research that we're doing is extremely exciting.

The reason space missions need artificial gravity is clear: humans simply did not evolve to live in zero gravity.

Our bodies are the subject of many experiments, but these experiments on the space station sometimes take years because in order for a scientist to get 10 data points, that can take six or seven years.

Sometimes astronauts feel a little ill or get minor scrapes. I trained as a crew medical officer to do basic treatment.

The space program is a peaceful project. The next door is opening. We have to go farther into space. But, before that, we need to develop far more improved nutrition and more advanced spacecraft.

Sequencing DNA on the ISS will enable NASA to see what happens to genetic material in space in real time, rather than looking at a snapshot of DNA before launch and another snapshot of DNA after launch and filling in the blanks.

Zero G and I feel fine.

Man is not made for space. But with the help of biologists and medical doctors, he can be prepared and accommodated.

I could have gone on flying through space forever.

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.

Very little useful science got done in the space station. NASA never did the experiments needed to develop the technologies required for a genuine interplanetary expedition: centrifugal gravity to avoid bodily harm and a truly closed biosphere.

Sex in space is not just a good idea, it's survival.

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.
