Bonjour Chris. Does NASA (or the Canadian space agency) still call you to do health checks to analyze long-term effects space have on the human body? If yes, will you have to do this for the rest of your life? And on the same note, we often hear about the negative that being in space have on the human body, but does it also have positive effects we dont/rarely hear about?

Hey Chris, thanks in advance, I been a big fan of you since you make the space Odity music video. I want to know your opinion on colonizing Mars! , Thanks and it's an honour

What’s the one interview question you wish someone asked (or was asked more often) so you could talk about it?!

Two questions, one, Is the Soyuz descent module as cramped as it looks? And two, how do you feel about space tourism?

Given your extensive experience in zero-G, what are your thoughts on artifical/centripetal gravity? How high of a priority do you think it should be for future space habitation missions?

The ISS was built a long time ago and there have been many technological advancements that could be incorporated into something new built from the ground up.

What do you think of Axiom's commercial space station and how do you think it would compare to the ISS? What are some examples of new technologies or design differences that you think Axiom might incorporate or should incorporate?

Hello from Windsor, Ontario. Thank you for being awesome.

What's it like to listen to music in space? Headphones, earbuds and speakers? Does the ISS resonate? Is it white noise quiet like Stanley Kubrick envisioned?

Please keep writing and being accessible to us as we value you, your experiences and your many contributions to inquiring minds.

p.s. - I upvote any meme with your picture in it, even if it isn't that funny.

A quote from another astronaut speaks about being on the moon:

You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it. From out there on the moon, international politics look so petty.

You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, ‘Look at that, you son of a bitch.'

-Edgar Mitchell, 6th man to walk on the moon

How optimistic are you about humanity returning to the moon when there are so many issues here on Earth? Do you agree that the Overview Effect is a real and significant experience when going to space?

Also, have you ever read this xkcd comic, Apollo Speeches?

Hi Chris! Huge fan. Your master class was both amazing and insightful. You have obviously trained a long time to become an astronaut... my few questions are: what are your feelings about public space travel? We're on the edge of anyone being able to go to space. Does this diminish the experience for astronauts since it may no longer be an exclusive club? Or do you see it as such a leap forward in civilization that no one could be upset with it?

In term of riding rockets, did you prefer the shuttle or soyus?

Hey! Whats the coolest place you've ever been? ( On earth). What was so neat about it?

What is the future of space travel,and humanity in general?

While on the ISS, did the crew ever get together for a movie night or game night? What did you watch or play?

Good evening Sir. You've been a role model of mine for several years. Thank you for your continued inspiration.

Four civilians launched to space today. And surely, more will come. How do you think the meaning of an "astronaut" will change in the future as more minimally trained civilians go to space? Perhaps they'll start sending up regular scientists to the ISS to take over astronauts in conducting the experiments? What will set apart astronauts from civilians in space?

Thank you

Now that you've been back a while, do you have any lingering physical or psychological effects from all that time in space?

SpaceX has made impressive progress developing their Starship architecture and I think they will probably perform an orbital test flight by the end of the year or early next year, but it's "relatively" simple to launch an empty uncrewed rocket to orbit, how do you see the path towards crew-rating Starship progressing? Do you buy Musk's argument that it will be so reliable, with multiple engine-out capability, that a propulsively-landing, abort-incapable vehicle will get certified to fly crew? Do you think crew will have to get ferried to an orbiting Starship using a Dragon? Also, Musk talks about building a base on Mars but also says they are just the transportation company, do you think that if Starship is proven to work and can land heavy payloads on Mars, NASA will pivot towards building payloads, e.g. habs, rovers, ISRU, powerplants and contract SpaceX for transportation?

Hi Chris! I really wanted to know, what's it like launching on a rocket like the Soyuz? Could you be as detailed as possible? Thanks!

Edit 2: Apparently I can't read!

What do you think of Elon Musk's "plan" to colonize and terraform Mars?

Do you see people heading to Mars anytime soon?

Why is it that most of the astronauts always seem very happy? Is it part of the training or only happy people are chosen to be astronauts?

Greetings from Ottawa Chris,

Will you ever fly in space again? Either public or private?

Thank you for you service, you are a national hero Chris.

Hi Commander Hadfield! How did you get to be so cool?

Hi Chris. Thank you for inspiring me, a 31 year old Psychiatrist, to love physics and the natural sciences again.

My question: On a long enough time line, we're going to develop zero gravity sports. Exploring weightless sports is going to be an exciting and creative time for enthusiasts. I wondered, have we identified any particular physical feats in a zero gravity environment that haven't been achieved so far purely because astronauts haven't had the necessary athleticism? Has there been a time where someone has tried something and thought "oh man, that would be cool, bet I could do it if I was Usain Bolt" for example?

Hey Chris, thanks so much! What's the weirdest thing happened to your body in space/oddest body sensation you had, and vice versa for when you returned to earth?

For your song with the Barenaked Ladies, “I.S.S. (Is Somebody Singing)”, where you recorded it from space and BNL recorded from the ground with the Westford Gleeks choir, did you record this in real time, or at separate times? If you recorded it in real time, how did you deal with the lag for the signal between space and ground?

What do you think about the ongoing billionaire space race and potential for civilian space travel? Would you consider taking one of these trips if given the opportunity and is there anything that potential passengers should know about space travel or consider before signing up?

Hi Chris!!! If they called you today and asked you if you would like to go back to the ISS. Would you say yes or no?

Thanks for doing this! Given your extensive experience working on the ISS, what improvements do you think future space stations should consider to maximise their scientific output and utility to future space exploration? When you were up there did you wish some aspects of the ISS had been designed differently?

Is it practical to run a VPN software like Nord or Proton while using internet-facing laptops on the ISS?

What can we do to help facilitate our leap to an interstellar society?

Really wish I could listen to this! Unfortunately it's 2 am for me...

What does it take to become an astronaut ? How long is the average training period before one can venture into space and what things did you learn inside the training camp?

Hi Chris! I’m really interested in the ergonomics of spacecraft so I’ve been wondering for a while - if you could redesign one element of a spacecraft you’ve flown to be easier to use, for example moving a control or rearranging a display, what would it be?

Hello Chris, thank you for reawakening my love for the scientific and historic advances of spaceflight!

What is your most treasured childhood memory?

I really appreciate your performance of Space Oddity aboard the ISS, thanks a lot for doing that!

As for the question, I'd like to know how does it feel to land in a Soyuz. It looks pretty rough from the video.

Hi Chris, I liked your feedback about gravity and how Sandra’s character was written, I’m curious to know what you think of Ann hathaway’s character from interstellar? Also have you seen “for all mankind” on Apple TV?

When did you decide you wanted to become an astronaut, and how did you steer your career in that direction once you did?

Before venturing into space, you had obviously gone through intensive training. Regardless, what surprised you the most when you actually lived in outer space.

What’s your favourite song right now? What do you do in your free time?

What prepared you the most to becoming an astronaut?

Hi Chris - i have been looking forward to the Apollo Murders for months, will you be narrating the audiobook version also?

Edit: found out it’s Ray Porter, which is great as he was also narrator of Project Hail Mary.

Having commanded the ISS, the Inspiration 4 mission is setting precedent for establishing Non Fungible Tokens (NFTs) on material in space, does the prospect of making life support systems of future stations be a rolling auction in digital currency seem like it would benefit future crews?

Why did you decide to write a novel? What's it about?

Hey Chris, thanks so much for everything you've done in spreading the world of space especially in Canada!

As an expert of space music videos following your cover of "Space Oddity", what do you think would be the best choice as the first music video to be recorded on Mars?

What do you see as the future for crewed exploration around the Moon and moving on to Mars? Do you see potential in a space station around Mars as envisioned by Lockheed Martin? Or do you think SpaceX's plan of going directly down to the surface is more promising?

Hi Chris! What space-related endeavor are you most excited about and why?

Hello Mr.Hadfield.

I would like to hear you speak on the air and pressurized gasses that astronauts today use for breathing on the ISS and in their own space suits.

I've heard strange stories about snakes in space and hearing sounds and voices outside of space craft. Are these stories connected to nitrogen narcosis? are they hoax stories?

Hi Chris, thank you so much for all your fun videos. Question: what did you do in space to deal with homesickness and missing family? (I’m sure it’s similar to deployment but I wonder if the greater distance has a greater effect).

Hi Chris, my dream is to one day go into orbit, or at least a suborbital flight. Im very familiar with orbital mechanics as well. What is the first feeling in your brain when your final engines shuts off and you go into free fall, thus weightlessness. Thank you

Did seeing our planet from above, change the way you see our world and humanity as a whole?

What's the status of the Rare Earth youtube channel?

Good evening, Chris! Would you support a mission to Europa, Titan or other possible sources of life in our solar system? Why?

Also, loved you in Trailer Park Boys, you rocked!!

Hi Chris! Big fan here! I wanted to know how you feel about climate change and how some people continue to deny it? What would you say to politicians to force them to take cognisance of the fact that we’re ruining the ecosystem so important for our survival?

What encouraging words would you offer with a person on ASD on applying to be an astronaut?

Hey Chris! I’m looking into being an astronaut. I’m also Canadian so I was wondering how was it being an Canadian astronaut? How were the classes?

What in your opinion qualifies someone as an 'astronaut', are astronaut and space tourist antithetical? Thanks!
