Andy Weir Quotes

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.

We were only on orbit a little over two days, so we had no adverse effects from being weightless.

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.

Zero G and I feel fine.

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.

Life as an astronaut in space is a very interesting one. There are things we all take for granted here on earth, like gravity, that can make things a bit challenging. One of the fun things about getting here is the zero gravity and floating around. But it also makes things very difficult.

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.

Everyone that I've talked to who's been to space has thoroughly enjoyed the experience, and what you often hear them say is: It was great, but we just had to come home.

I've been approached to do some things with astronauts and the preparation that astronauts go through.

Adjusting to space is easier than adjusting to Earth for me.

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

A lot of scientists on Earth think of things that they could do in zero g. Things like the way metals cure, for example, and the way fluids react in space can tell us a lot about some of the unknowns we have on Earth.

Mars missions will require up to three years in reduced gravity, so we need to make sure astronauts can not only survive but thrive as they move outward to explore this new world.

Now, I've never flown in space; but the folks who have say that on landing day, you know, you've just spent maybe a week and a half, sometimes two weeks in orbit and you're used to the things happening slowly in space.

This has been a great experience for me. The first couple of days you don't always feel too well. You adjust to the fluid shifting, how to fly through space without hitting things or anybody else. But then you get in a groove.

In space, you need to exercise your heart since it's not pumping blood around at the same rate.

One of the coolest things to me about living in space was it really caused me to think about how the human body and mind can adapt to completely different environments.

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.

Up in space we don't have a huge wardrobe.

Gravity on Earth provides a force that keeps our bones and muscles working. In the microgravity of space, our bones and muscles are not taxed, so they begin to atrophy.

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

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.

In space for a short time, I think most people could survive that. If you're sending an average person who's healthy for a short period of time, I think that's quite doable.

Just like the bones and muscles, the heart is designed to work in one gravity here on Earth, so when you put the heart in space, it operates differently and changes shape.

Gravity is a really heavy force and you don't realize how heavy it is until you haven't felt it for six and a half months.
