To facilitate getting less repeat questions from the last AMA, what I've done is answered a number of the "standard" interview questions up front, including those sent to my son in PMs the other day. I will provide them below in individual posts.
What are you bringing with you?
The Soyuz is very small and the weight balance affects how it flies, so we are very restricted in what we can bring. I thus chose small items for my family and close friends: a new wedding ring for my wife, commemorative jewellery, a watch for my daughter (I flew a watch each for my sons on previous flights), a full family photo for my Mom and Dad, and some mission emblem guitar picks.

Aliens
No astronaut has ever seen an alien, despite what popular media would like you to believe, though we are, of course actively looking; it's one of the basic purposes of exploration. As we speak, the Mars rovers are hunting for signs of life on our nearest neighbour. I'd love to help discover life somewhere besides Earth, but it's important to keep perspective and reason: while everyone often sees things they don't understand, to immediately label them 'UFOs' and conclude that they have to be alien life is just wishful thinking and a bit silly. Don't confuse entertainment and lack of understanding with fact.

Sex in space
People have sex on Earth all the time. It is a normal, basic human function and fundamental desire, necessary for the propagation of our species. It is also steeped in cultural and personal significance, and thus gets extra attention. There will, of course, be sex in space, just like everywhere else, but for a small crew, the subdividing emotional attachment that goes along with it could be very harmful. We also have had very limited hygiene and privacy to this point. With bigger and bigger crews and spaceships, however, it will become a natural part of human existence in space, just like on Earth.

Pooping
Our Space Station toilet looks like a camping toilet, and uses airflow in place of gravity. When waste comes out of the body, either solid or liquid, it is pulled into the toilet by airflow. The urine is mixed with other waste water (humidity, water samples, etc) and purified back into drinking water. The solid waste is collected in a small sewage tank and put into an unmanned resupply ship, that is then jettisoned and burns up in the upper atmosphere.

What do you have to do to become an astronaut?
Astronaut selection requires 3 fundamental tenets: health, brains, and experience. You have to be able to pass the toughest medical in the world to be a Space Station astronaut, so stay in shape and eat right. You have to demonstrate the ability to learn complex things, so an advanced technical university degree is needed. And you have to demonstrate good decision-making when the consequences really matter, so important to have work experience such as a medical doctor, or test pilot, or saturation diver. That will whittle the selection group down to several hundred - after that other skills matter: languages, flying experience, diving experience, personality, attitude, how you present yourself. And above all, a driving, fundamental desire to be an astronaut is required, to successfully endure the life demands of the job.

Did spaceflight change religious view?
No one gets to be an astronaut without a strong personal conviction that gives them strength and confidence. No matter what religion or creed they believe in, all astronauts have something fundamental within themselves that they can draw upon. The actual experience of space travel in fact deepens this, reinforces it, and accentuates the awe and wonder that are at the base of it.

What do you miss the most?
I miss a hot shower, fresh food, the smells and variety of Earth, and direct human contact.

Are you scared?
Fear comes from being unprepared when facing the unknown. Being thrust into an unexpected situation and not knowing what to do makes everyone uncomfortable, and thus we fear it, especially if it can embarrass or kill us. As astronauts, we avoid this by working for years to understand the unknown, and decide in advance what we will do. That's why we study so much, and why we live and work in simulators. Often the 1st time you try something hard you are nervous, but the 50th time it feels normal. We try and make everything that might happen during a spaceflight feel just like that. So it's not that we're extra-brave - we're just extra-prepared.

Won't you be lonely?
In the centre of every big city in the world, surrounded by noise and teeming millions of people, are lonely people. Loneliness is not so much where you are, but instead is your state of mind. On Station with the world in our window, people on the radio, family just a phone call away, and other crew members to chat with, plus a full plate of experiments and work to do, loneliness is no more of a problem than it is everywhere else.

How's the food?
Space food is fine, tasty, and of good variety. It's limited to food that has a long shelf life, with no refrigeration and no microwave, so it's a lot like camping food or Army rations. The majority of it is dehydrated, so we add cold or hot water to it, like Ramen noodles or instant soup or powdered drinks. But we have a mixture of Russian and American foods, plus specialty items from Canada, Europe and Japan, so we eat well, and also use dinner as a good time to get together and talk, relax, and be human.

Why spend money in space when people are hungry on Earth?
In all societies, we need to balance how we spend our money. The vast majority needs to be on human health and services. A portion also needs to go to education. In addition, some needs to be for research and exploration. It is vital that we take care of our people, educate our young, and develop opportunities for the future. If we don't challenge our citizens with demanding ideas and possibilities, they will either go elsewhere which is a loss, or not realize their potential, which is a tragedy. The key is to decide what is the right balance of budget, and when you look at the actual figures, I think the Space Agencies of the world get it about right. I know in Canada we work very hard with the money we are given to do as well for our country as we can - developing useful products, better understanding the world and human health, and inspiring our next generation.

What does launch feel like?
Launch is immensely powerful, and you can truly feel yourself in the centre of it, like riding an enormous wave, or being pushed and lifted by a huge hand, or shaken in the jaws of a gigantic dog. The vehicle shakes and vibrates, and you are pinned hard down into your seat by the acceleration. As one set of engines finishes and the next starts, you are thrown forward and then shoved back. The weight of over 4 Gs for many minutes is oppressive, like an enormous fat person lying on you, until suddenly, after 9 minutes, the engine shut off and you are instantly weightless. Magic. Like a gorilla was squishing you and then threw you off a cliff. Quite a ride :)

What language do you speak?
I grew up speaking English, learned some German in high school which I unfortunately mostly forgotten, and since studied and learned French and Russian. On station English and Russian are the standard languages, and all astronauts are trained in both.
Has any astronaut ever passed out during take off? Did someone have to wake them up or did they wake up on their own?
No. The reason is that the blood doesn't drain to your feet. You're lying on your back so you don't black out.
Tell us about some of your favorite space foods!
Shrimp cocktail. Because the horseradish sauce has a really strong, sharp flavour that survives rehydration.
Has anone ever shit themselves?
Ha! No. We're not beginners, and we're not unprepared. We train for years so that we're ready to do our job properly.
That's awesome. Is there a sudden change from light to darkness or does it happen gradually?
It takes about 15 seconds from being in the sun to being in complete dark. It is like sunset happening completely in 15 seconds.
What country has the best all around food in your opinion?
I think I like Russian space food the best. It has the most natural flavour and it is more like the comfort food that I grew up with.
It seems like with the heavy cost of getting stuff into orbit it would make more sense to keep the waste up there until (at some point in the future) it could be recycled for growing plants or something. I know NASA has made at least token gestures to creating fully sustainable habitats.
Is it just the cost of fuel to stabilize so much mass that makes it necessary to burn up the waste instead of keeping it around?
The Station only has so much space inside, pun intended, like a sailboat at sea, and with new equipment arriving all the time. We have to put the trash out, just like everyone.
Do you have poutine or some substitute?
Poutine
I wish we could! I love poutine, especially on a cold day. But it doesn't keep nor travel well, and definitely isn't suitable for freeze-drying :)
What's one of the Canadian specialty items? Kraft Dinner?
Maple syrup, maple cookies, buffalo cranberry jerky, blueberry bars, chocolate, Holy Crap cereal, specialty honey ... lots!
Can you misplace stuff on the ISS, or does the fact that nothing can be dropped minimize that?
I imagine astronauts tend not to be absent minded, but I lose guitar picks all the time. There would a filter somewhere covered in guitar picks if i went to space...
When things don't stay on the table or fall to the floor, you lose them ALL the time! So we use Velcro a lot, on almost everything.
I think what you're saying is that the sheer experience and beauty of seeing Earth from a rare viewpoint reaffirms whatever you believe in. An atheist or theist alike would still have newfound faith...in the wonder of nature and the universe, just getting a scale of how large it all is and how insignificant all of our petty day to day problems are. If you associate that with a god, then your convictions and faith to that god would understandably be reinforced.
Precisely. Regardless of what they believe beforehand, I find spaceflight enhances a person's views, as opposed to greatly changing them.
How well does the giant swimming pool (NBL) simulate weighlessness? Can I just skip Zero G?
Pretty well. The advantages are full-size, tools and equipment being just right. The disadvantages are that there is drag in the water, and your blood rushes to your head when you're upside down.
What do you hate about being in space? What's the worst part?
I don't hate anything about it. The worst part at first is motion sickness, then later that you can never have a good shower. You can't properly clean your body like you can on earth. You can only just have a sponge bath.
Follow up: has being in space made you hate anything about Earth?
No. But being in space makes me feel like I need to take batter care of the Earth. To be a good steward and advocate. To pick up trash when I see it, to notice the beauty that surrounds me, to recognize what's precious.
I try not to hate anything - it's rarely a motivator to do something good.
How bright are the lights on Earth when you are in orbit at night? How does it compare to the stars we see on the surface of Earth?
Yes, it looks like stars from the surface of the earth, but not nearly as bright as the moon. The brightest things are lightning storms. You can see lightning storms at night for thousands of kilometers. Regular lights just look like stars from the earth. Big cities stand out as one big local glow.
This is an excellent question. Nobody ever asks this.
Hello Commander Hadfield! First off thanks for doing this AMA and if possible the AMA from space, just 2 questions for you:
what is the best part of being/living on the International Space Station?
When you come back form prolonged stays in space what is the first thing you want to eat?
(Also if your space AMA does happen I think all of Reddit is expecting a super awesome verification photo.)
The best part is being weightless forever. It is like magic. It is like having a superpower where you can fly. You can fly forever.
Hello Commander! thank you for doing this!
On a high level, how does what you experience with the Canadian Space program differ from what most astronauts experience with the US one?
What should Canada be doing with its space program going forward?
Any good restaurants in Kazakhstan that you can recommend?
Favourite place to travel to that doesn't start with an "S" and end with "pace"?
Being from Sarnia do you cheer for the Leafs, the Red Wings, or someone else?
I see in your past you have been a test pilot - Favourite aircraft to fly?
EDIT: spelling
On a high level, how does what you experience with the Canadian Space program differ from what most astronauts experience with the US one?
The big difference is that the US has launched vehicles. Americans fly in their own space ships. Canada has never had human launch vehicles, and we have always flown in other countries' vehicles. It is sort of a space between ownership and being a guest.
What should Canada be doing with its space program going forward?
Doing what it is doing. I think we're doing the right thing right now. We are looking at Canada's needs and cooperation internationally, making sure that Canada is involved in everything from the Hubble telescope to studying pollution in the atmosphere to being on Mars to commanding the space station.
Being from Sarnia do you cheer for the Leafs, the Red Wings, or someone else?
The Leafs.
I imagine that your job is pretty high-stress, what do you do at home to relax and unwind? Hobbies?
I try and manage my stress at work, not at home. I think that's an important thing to note. Stress normally occurs when you can't solve a perpetual problem or you can't get comfortable with a certain idea. When you can't control your own destiny. I try not to let myself be that way. I try to truly accept the things I cannot change.
I like to show up at home not stressed. But to answer more directly, I run, I play guitar, I go for walks.
May I ask you if you learned the way you think about and view the world from someone in particular, or did you learn on your own?
Who is your favorite guitar player, and which song is your favorite to play?
thank you for the AMA :)
Favorite guitar player
Mark Knopfler
Hey Chris! Congrats on becoming the first Canadian to command the ISS. As a fellow Canadian I gotta know, what's in store for the future of the Canadian space program? Is there any point hoping for a Canadian shuttle or moon landing in my lifetime, or should we just keep on bragging about the Arm? Thanks for doing the AMA and good luck on your mission!
Is there any point hoping for a Canadian shuttle or moon landing in my lifetime
Building your own human launch vehicle is extremely expensive. It makes more economic sense to cooperate internationally with people who've already developed that capacity.
If you were President, what would your plan for NASA be?
Do you think NASA will ever be able to accomplish a long term space plan when the Presidency changes hands every 4/8 years with each new President trying to put their touch on NASA's accomplishments?
What recommendations do you have for someone trying to get a job at NASA? (not necessarily as an astronaut)
Do you think NASA will ever be able to accomplish a long term space plan when the Presidency changes hands every 4/8 years
Yes. It is easy to despair, but it is better to look at history. It has never been easy to organize a major project. But we've done it anyway, and there are lots of examples. The Space Station is a long term space project, the Mars rovers, Voyager, Messenger orbiting Mercury. All of those, plus the hundreds of satellites orbiting Earth -- those are all part of the long-term space plan. It's not perfect, but we're making it work anyway.
How is preparing for a Soyuz flight different to the preparations you had to go through for Space Shuttle missions?
Also, how can you best describe the feeling of looking down on Earth from orbit for the first time?
How is preparing for a Soyuz flight different to the preparations you had to go through for Space Shuttle missions?
A shuttle mission is an end in itself. It is limited by the amount of time a shuttle can stay up (about 2 1/2 weeks). A Soyuz flight is going somewhere, and staying there for half a year. A Soyuz flight is part of a long mission. A shuttle flight is a mission to itself.
To further that, the Shuttle is far more complicated than the Soyuz. As well, as a Canadian I can be a Soyuz pilot, but could not be a Shuttle pilot. Soyuz parallel parks better, too.
With the retirement of the shuttle progam, how can NASA (and the space program in general) remain relevant to the US populace?
The shuttle program was only one of many NASA programs. It was a way to get to space and back, and the purpose of spaceflight is not to launch and land. It is what you do when you get there. With all of the unmanned vehicles, and with the space station that we've built, the relevance for the populace is huge and permeable. As well, the US is working on building follow on vehicles.
If you could bring one famous person into space with you, who would it be?
One non-famous person?
Assuming I already had a competent crew, so that I wasn't counting on this person to operate the vehicle and keep us alive, I would bring an extremely talented artist. One who could capture the experience in a way it had never been captured before.
That may be a songwriter (such as Stan Rogers, if he were still alive) who could put a profession -- a way of life -- into perspective.
Commander Hadfield,
My question does not involve space, but your history as a test pilot.
I heard when you were a military test pilot you were the one who invented the maneuver to get out of a death spiral/spin in a fighter jet. I have a few questions about this.
Was it all done in a simulator? did you ever get a chance to try it in a real jet?
Has anyone ever had to use your maneuver in real life? And if so did you ever get a chance to speak to those pilots?
In closing Id just like to say you are a true Canadian hero and an inspirational bad ass.
Was it all done in a simulator? did you ever get a chance to try it in a real jet?
Yes, I did. Simulators all have serious limitations. Our test program was initially approved in a simulator, but all the real testing was done in flight in f-18's. We rewrote the procedures for out of control flight recovery. In the test program, we put the jet out of control around 120 times. However, I have only accidentally had an F-18 in an out of control spin once, and the recovery procedures worked (during a practice dog fight).
Thank you for being an envoy of all mankind (UN Outer Space Treaty). What's the strangest thing you've seen up there?
A huge meteorite burn up between me and Australia.
How big a threat are micrometeorites to the ISS and how do you deal with them?
How big a threat are micrometeorites to the ISS and how do you deal with them?
We get peppered by micrometeorites all the time, but the Station has armour. It won't stop a big one, but we have emergency response prodecedures if we get a puncture.
Hello Mr.Hadfield,
We are a grade 6 class from Saskatchewan Canada and we are studying space. Our class was excited to hear that you were going to be answering questions about anything! Our class got together and thought of some questions that we would really like to know.
How does your body feel after being in space for 6 months?
Are you excited to meet the ISS robot: Humanoid Kino Bot in 2013?
What did your family and friends think about your dream of becoming an astronaut?
What does space foot taste like? Is it good?
How does your family feel about you going back into space?
How did it feel when your saw earth from space for the first time?
What does zero gravity feel like?
How long do you have to go to school to become an astronaut?
Were you nervous for the first time you went to space?
Thank you for your time,
We really hope that your flight on Wednesday December 19th, 2012 is both safe and successful. We are very excited for you, a Canadian, to run the international space station. Good luck, we will be watching
How does your body feel after being in space for 6 months?
Adapted. You feel like a spaceling. You feel completely normal, and don't even remember that you're flying. There is no up or down. You are really no longer an earthling, but a spaceling.
Are you excited to meet the ISS robot: Humanoid Kino Bot in 2013?
I know of Robonaut on board, but I'm more excited to see Canadarm 2 again. It is a much more capable robot.
How did it feel when your saw earth from space for the first time?
It feels like someone's revealing a secret to you. Like you're getting to see something magic for the first time. It feels like an honour. Like a huge privilege.
How does the humanoid robot move around the station i can find any information on that.
Robonaut works in a fixed location inside ISS. We put it in place. There are plans to bring up legs for it, and eventually it will be able to move on it own, but it's still in early testing and certification.
Do you consider yourself a science fiction fan? If yes, what material in particular?
Yes, I am a science fiction fan. I grew up as a science fiction fan. I like Arthur C. Clarke, Issac Asimov, Robert Heinlein. I like Edgar Rice Burroughs, Star Trek.
That said, nowadays I prefer science fact.
What does it feel like to look down on earth during a space walk?
It is wildly beautiful, the colours and textures, the global view, the chance to have the Northern Lights ripple under your feet. Stupefying
What is your biggest fear associated with embarking on a mission?
That someone I know and love on Earth will get hurt or die, and I won't be able to help or be there.
Do you land in Kazakhstan on the return flight?
Yes, after 5 months in orbit, we'll land on the open Kazakh prairie, normally near Arkylyk, a few hundred km from where we launched
Are you mentally at work all the time during the mission, or will you feel like you can 'get away' for a break now and then?
I will deliberately mentally get away. Play guitar by the big cupola windows and steal some time to truly appreciate what is actually happening - to me, and in history
Do you ever have the 'John Glenn' feeling when you are sitting on top of a giant rocket built by the lowest bidder?
Part of the job of being an astronaut is trust in others - I have no choice, and it has worked for me so far.
So I see that your username consists of, not only your name, but also "Col"
If I shouldn't be all too wrong, and my gaming ranks are right, "Col" stands for Colonel.
Is there a reason for you to write it in your name? Do astronauts get rankings concerning their order of command? Does the "Col" stand for something else? Or is it simply to fill out some space?
I served Canada for 25 years in the Air Force, and was eventually promoted to the rank of Colonel.
What is your educational background?
I have an BEng, an Masters in Aviation Systems, and graduated from Test Pilot School.
Favorite part about your job, go!
The great people I work with, pushing themselves and me to the limits of what we can do with our lives.
What does zero gravity feel like?
Like magic, like a genie touched your head and said "Fly!"
What is your preference, earth or staying on the ISS?
Luckily, astronauts get to do both. I prefer it that way.
Not sure if questions are still getting answered, but here are a couple,
In your opinion how serious is the threat of space debris and consequently, would you like to see a more serious effort at collecting said debris?
What are your thoughts on private companies such as SpaceX? With decidedly less government involvement in the development process, are you comfortable with this?
Thanks for taking the time out of your schedule!
Space X is an excellent company, working hard to make spaceflight as safe and inexpensive as possible. It's the right direction to be heading.
Can you reddit from space? How? If so, what are the speeds like?
I'm not sure, our connection is intermittent and slow, but if I can do an in-space AMA, I will!
What do you actually do? It seems like whenever people picture astronaughts, they just picture a bunch of people hanging out in space.
The Space Station has 130 experiments running simo, from studying the human heart to collecting dark matter from the universe to measuring the health of Earth's atmosphere. We run the experiments, and the building, and fix everything that breaks.
What would you say to a young woman in high school that loves science? Any words of advice/wisdom?
Study what you love, and learn it as well as you possibly can - pursue your passions.
Hi Commander! Thanks for answering our ridiculous questions! Just a real simple question for you...
What does the space station smell like to you? Does it smell like a wet laundry room with a strong copper overtone, or an automobile shop?
Thanks!
The Station has no distinctive smell - it is clean and well-maintained, like being inside an airliner, maybe.
How do you properly trim your moustache on a mission?
I'll trim my moustache with scissors and a vacuum cleaner.
Col. Hadfield, thanks for doing this IAMA. I wish you the best of luck in your upcoming launch.
As for my question -- I have heard that space has an odd scent/"taste", very similar to a type of metallic. Is this true? If so, is it a nauseating scent?
Again, thank you and best of luck!
When we come in from a spacewalk the airlock has a distinct smell, like gunpowder or ozone - that is the smell of space.
What is it like to sleep in a weightless environment?
I know you are essentially strapped in but does it still feel like you are floating?
Does that make it easier or more difficult to sleep?
Sleeping with no gravity is wonderful - you can relax EVERY muscle, you don't need to roll over, you don't need a pillow - VERY comfortable!
what do you tell people who believe that the moon landings are all faked? Thanks for doing this by the way!
They should look at the photos of the tracks and Lunar Landers sitting on the Moon :)
Is there available exercise opportunity on the space station? The effect of long-duration time periods in microgravity must have an impact on your body when you return to Earth. I once saw a picture of a treadmill that straps you into it with resistance bands, does that still exist on the space station? Do you or other astronauts suffer from orthostatic intolerance, muscle wasting, bone mineral density loss once returning to earth? Is there a specific amount of pre-flight exercise training to boost your fitness to combat any potential loss of muscle? Thanks, and good luck!
We have the ARED - Advanced Resistive Exercise Device - like a big squat machine, and work out 2 hours per day. With that, we have largely beaten osteoporosis.
Hello Chris, look like you found a good way to dodge the Canadian winter! Godspeed up there, we're all behind you here at the J.H.C. Space Center.
I've been in Russia and Kazakhstan for months - I dodged nothing :)
Is shaving difficult in orbit?
Shaving is similar, though you can't rinse your razor, so we use them up faster. We use disposables.
What watch do you wear in space? I know the Omega Speedmaster has popularity because it's been worn in space, on the moon, etc.
Curious what astronauts are wearing these days.
I bought an Omega Speedmaster, very useful for spaceflight.
How do you scratch your nose when you're wearing one of those space-suits?
We have a squishy thing inside we jam our nose into while we clear our ears - we scratch our nose on that.
What does it feel like to go from being weightless for months, back to your normal weight on earth? Must seem incredibly weird...
It feels so ... unfair! Even your ARM is heavy. It takes about 1 day on Earth for every day in space to readapt.
I've been following you for years, been a fan of the space program as long as I can remember. I still remember being at a birthday party and having the movie turned off so the adults could see the news of the Challenger disaster. As a fellow Canadian I'd like to say I'm proud of you and think you are incredible. Thank you!
Thanks!
You are amazing, first of all.
I feel that 'space' is anything but space. It is full of energy, whether on Earth or in actual space. When you are spacewalking, do you feel as if you are moving with some kind of current?
Not at all - you are in a perfectly smooth, frictionless vacuum, moving near-effortlessly.
What games do you play while in space? I suppose playing poker doesnt require a table
I invented a form of darts - with a heavy metal knob that had a velcro sticker on it, a long zip-tie as the haft, and a handkerchief parachute to slow it down, all duct-taped together. I aimed at Vecro on the walls, threw it slow and straight - worked great!
I am an aeronautics engineering student and I am on my last year before getting my degree. Going to space has been a gear dream of mine for as since I can remember and that is how I aim to make that dream come true. I hope I can get in the ESA (Since I'm European) and make that dream come true.
People like you and those who went in the space before you inspired me. People who are pushing the limits of the human race. People who make the human race better as a whole. The contribution of s the effort to explore space has been immeasurable and I hope to be part of it.
My question has to do with the dangers of such an operation. The way I see it going to space can be the most dangerous thing a man can do. But at the same time the most rewarding. So what in your opinion is greatest danger out there and what ways are there in your opinion to avoid them.
Good luck and be safe out there.
Worthwhile things often involve risk. The secret is to balance risk vs reward. I am NOT a thrill-seeker. I take calculated risks to do things that I deem worthwhile. Like being strapped into a Soyuz rocket in 6 days.
Hello Commander Hadfield.
Would you ever consider putting a Geocache on the space station for the next astronauts to pick up and sign?
What is your favourite song, or is there one that inspires you in what you do?
What is your greatest acheivement?
What is your favourite film? I know questions like this are generally frowned upon but I'd like to know a bit about Commander Hadfield on a personal level.
What's the coolest gadget on the ISS?
Thank you for taking the time to do this AMA and good luck on your endeavours.
I'm really looking forward to pointing at the ISS with my nieces and nephew and saying I've had contact with one of the people on there. I am very keen to get them into science and you could just be the man that gets the curiosity started. Thank you
The coolest gadget on ISS the the AMS - collecting dark matter and high-energy particles to try and figure out what the universe is made of.
Hey Commander Hadfield! Awefully great of you, taking time to answer questions and everything! I was wondering, what place on earth reminds you the most of space?
Being underwater, especially when I lived on the ocean's floor for a few weeks.
Okay so that sounds awesome. What were you doing that for?
NEEMO 14, in an underwater lab.
Did you have to undergo severe G force training?
Yes - I flew the world's largest centrifuge in Star City, Russia, to practice manually flying the Soyuz home through the atmosphere. It can get to >20G, but we only go up to 8.
Hows your day been so far?
My day has been fine. We did a media tour of Quarantine here in Baikonur (they were all wearing masks so we wouldn't catch their colds), I exercised, I studied, I did emails, and now I'm doing an AMA. I also ate well - the food in Quarantine is good!
What are your thoughts on potentially every country coming together and making an Earth space program so that we could refine our priorities and hopefully go bigger, better and further in space?
International cooperation is difficult, especially with finance and risk, but the ISS is a shining example of success in that area. I think we are doing what you suggest.
My friend (at York university enrolled in space science) and I got into an argument about if your hometown is where you were born or where you grew up. Having lots of family in Sarnia and growing up in south western Ontario, i always thought you were a Sarnian (considering they named the airport after you) however him growing up in Milton believes you to be from Milton could you put an end two this conundrum ?
I spent the 1st 8 years of my life in Sarnia, and the next 8 in Milton, so they are both my hometowns. That's where I grew up, and became the adult that I am.
Two questions.
What does "space" sound like?
Have you had any unexplainable happenings while in space? Eg- UFO
Space is absolutely silent. With no air to transmit sound waves, there can be no noise.
So when you're out on a spacewalk, all you hear are radio transmissions and your own breathing.
I was just thinking, once you have been to space... What else can you do in life that can even come close to such an achievement or be so fulfilling?
Interesting question, one of perspective. I find every day fulfilling. I work hard at what I'm doing, I do it as well as I can, and I find satisfaction in every small thing.
It is not like my life is compromised so that I can fly in space. I love each part of each day, AND I fly in space.
I think it's largely how you look at it.
This question was sent to me yesterday when my son was announcing the AMA from /u/Tuesday_D:
I want to know about the differences in experience between NASA launches and Russian Space Agency launches and how that might change his perspective of the mission.
They are very similar - years of training, focus towards launch, dress rehearsals, a week or 2 of quarantine, a rocketship nearby getting fueled, suiting up, ride out to the pad, pressure checks, and ... launch! The differences are language, size and design of the ship, and Baikonur isn't Cocoa Beach.
What's it like playing Guitar in space?
The Space Station is noisy, as the fans and pumps have to move the air to keep us alive. So it sounds like playing in the back of a bus.
The best part is that the guitar floats in front of you. You don't need a strap!
You have to relearn how to bar chord, as without weight, your arm goes too far, and you overshoot.
How does it feel when being weightless in space back to your normal weight again? Also do you ever get any "alone time" in space? Thanks again for the ama. Reading about your experiences has been incredible
Yes, we get alone time during the 5 months in orbit. My sleep station is like a 1-person closet, and when I pull the door closed, it is private.
Also, the Station is BIG. You can work for hours and see no one else, especially when there are just 3 of us onboard.
How hard was calculus for you in the university?
I find theoretical math hard, but also useful. It's like using a complex machine to do something you couldn't do any other way, like a backhoe or a fly rod. Once you see the purpose of it and learn how it works, though, it gets easier. It just takes dogged work and repetition to figure it out. Also true for spaceships.

Since we are an international crew, we chose which annual holidays to celebrate. We agreed on 25 Dec Christmas, January Orthodox Christmas, and New Years, so we'll celebrate all three!
What kinds of new space technology are you most excited about, either stuff that's been made, or stuff that is in the works?
What excites me most in space technology is ... propulsion. We are very limited in what we have now, and to go to Mars or further we will likely need something better. The VASIMIR engine, the ion drive engines, much more efficient solar power, these all help point the way to the future.

I am bringing books, mostly as gifts for my crewmates. Ebooks are nice, but it's also nice to hold a book in your hands. I brought humour books (Dave Barry) and classics (Conan Doyle), and my wife has packed books for me as a surprise. I hope :)
Commander, how would you feel Hollywood has portrayed space travel? Specifically along the lines of "Apollo 13" and "Armageddon".....?
Apollo 13 was a great film. I thought it was well told and was quite accurate.
Armageddon on the other hand...
To the people who do not believe in the lunar landing, what do you say? Have you encountered anyone?
People disbelieve a lot of facts, and it is rarely wise to try to rationalize with them.
We have taken pictures of the equipment left on the moon. There is no question if we've been there, except to those who would rather believe than learn.
Have you ever gone into the shadow of the ISS or another space ship while on a space walk? If so what was it like? Is it total darkness?
Edit: Thanks for the response! And good luck up there! I'll watch you every night you pass over Chicago!
When in space, if you look away from the Sun, it is total darkness. It's because there is no air to reflect and refract the light around you.
You can even take a picture looking at the Sun. The bright Sun will be blown out in the image, but space around it will be black.
The only light becomes the glow of the Earth and starlight. Very cool.
When you're talking to other astronauts on the space station, do you all orient yourselves so that your heads are all "upright" respective to each other, or do you all grow so comfortable with the lack of gravity that you're able to talk at odds to each other's perspective?
EDIT: Canadian from Toronto, wanted to add we're all proud of you. We might not have a manned-launch under our belts as you mentioned earlier, but we contribute enormously to international efforts in near-Earth orbit and beyond. Thank you!
Having a conversation in weightlessness is like chatting in a swimming pool. Your sort of drift around, and don't always look at each other. But when you want to say something important, or be clearly understood, you need to get your heads lined up and make eye contact.
Maybe also like a conversation in bed.
What are you instructed to say when people ask you about spacecraft other than man made ones?
That's a funny question. I'm not instructed to say anything. My answers are honest and factual.
What was the most exciting thing you saw while going out there?
Had you been inclined to being an astronaut prior to going out for training?
Do you enjoy your job?
I've been working towards being an astronaut since I was a nine year old boy watching man land on the moon.
I love my job, and get a tremendous satisfaction from doing it.
Wouldn't the objective of off-Earth settlement be better served by sending a young couple on the upcoming Year Long Mission, rather than studying the effects of microgravity on 48 year old Scott Kelly??
Perhaps there is scientific merit in choosing different test subjects for spaceflight, but the key is we are not just there to be experimented upon. We also have to do everything - fly the spaceship, speak Russian, operate the Canadarm2, perform spacewalks, know all the systems, and stay healthy.
Scott has 15 years of hard-won experience that will allow him to command the ISS and safely stay there for a year. We stand to learn a lot from his service, as well as Michael's.
Are you really Canadian?
I am a true Canadian, yes, born, raised, Leafs fan, Tim Horton's maple dip lover, have lived in 6 provinces and visited them all, Rick Mercer advocate, speak 3 languages including French and English, know all the Stan Rogers tunes by heart and feel great pride in our home and native land. Thanks for asking.
White Oaks Secondary School represent! Thanks for doing this!
Go WOSS! I am a proud graduate.
When was the last time you ate a corndog?
Hmmm ... my last corndog was ... never. Not good astronaut food, sorry.
Do you think we will go to Mars (manned missions) anytime in your lifetime?
I sure hope we go to Mars in my lifetime. We have satellites orbiting it, rovers driving around and sampling it, and are learning on the Space Station how to build spaceships that we could trust to go that far.
One small step at a time, it's amazing how far you can go.
30 years ago, who'd have thought I'd been commanding a spaceship?
What was your favorite subject in school and why?
My favorite subject in school was English. I love the exquisite power of language, especially when well-used. It can sometimes turn our random thoughts and mental images into poetry and lyrics and speeches that truly communicate and inspire.

I decided to become an astronaut when I was 9, the day Buzz and Neil walked on the Moon. I have been working towards being one ever since.
My education, my experience, the skills I gained from 9 until 32 all were key in getting me selected.
And in the 20 years I have been an astronaut, I have studied and prepared pretty much every day.
Being an astronaut is not really my job. It is more a definition of who I have turned myself into.
Ever see anything weird up there? Aurora Borealis from space? Glowing atmosphere? The tops of lightning storms? Space debris, etc?
During my first spacewalk I was riding on Canadarm2 as the Space Station was coming across the Indian Ocean in the dark, at 8 km/sec. I shut off my spacesuit lights to let my eyes adjust, so I could see the lights of Australia.
But instead, I saw ... the Southern Lights. Thousands of miles of greens and reds, yellow and orange curtains billowing and flowing with light, pouring up out of the Earth under my feet. I couldn't believe it.
Could this really be the Earth I knew? How could this always be happening and I had never known it?
It gave be a new-found wonder at our ignorance, and really showed me our planet as a ball going around a star, just another planet, but an immensely beautiful one. Made me love our Earth even more.
Dear Redditors - it is late, and my flight surgeon just came in and told me to get to bed. We have lights-out here in Quarantine in 30 minutes, and I have to get back to my building and get to sleep.
Tomorrow we go get into our Soyuz spaceship. It's our final look inside before our launch on the 19th. We'll check where everything is in its final configuration, and make sure we're happy that it's ready for us to go to space.
A pretty exciting time in anybody's life, and hugely so for me.
Thanks for the great questions and dialogue, and for giving me a chance to try and share this incredible new human experience.
Goodnight from the Baikonur Cosmodrome
Chris Hadfield CSA Astronaut
One last thing - huge thanks to my son, Evan, who encouraged me to do this AMA, taught me how to use Reddit, and set it up for all of us.
Thanks, son!
Love, Dad
Do you believe in extraterrestrial life? What are some things you have seen or felt in space that you cannot logically explain? What is your biggest fear once your safely out of earths atmosphere (no counting re-entry of course)
I believe that in the vastness of space there is a likelihood of alien life. However, there is no evidence whatsoever to suggest that any creatures more advanced than man have ever been to earth.
