This week, Astronaut Chris Hadfield tackled even more questions from the Reddit community in his third AMA. It has been almost two years since he openly invited the public to ask him anything.

Hadfield, who is known for his cover of David Bowie’s “Space Oddity,” just released a new album earlier this month, called Space Sessions: Songs from A Tin Can. He said the vocals and guitar were recorded while in his sleeping pod aboard the International Space Station (ISS).

He spoke with the Reddit community about David Bowie, the feeling of being in orbit, and what the ISS smells like.

In case you’re wondering if David Bowie has ever heard Hadfield’s infamous cover of “Space Oddity”:

Interestingly, Hadfield wasn’t the one who brought the guitar into space:

And evidently, he’s not a fan of disco music:

Hadfield also reveals he has no interest in becoming a politician. For him, seeing Earth was almost like a religious experience. It taught him that the “us versus them” attitude is futile.

He doesn’t think we’ll be able to send people to Mars with our current technology.

He talks about what it feels like to go into orbit for the first time:

And, yes, Reddit user KeeperDe asked him what it smelled like aboard the cramped quarters of the ISS:

Finally, before he leaves the session, Hadfield shares his poignant philosophical take on how to pursue your love in life:

“Never hate what you are doing. Make the most of it, find pleasure in the nuance and the art of it, become better at it, laugh at it, make it one of the things that you can do. If it’s truly insufferable, then you must change and do something else. But get the most out of each step of life as you go. There’s always more there than you think. And celebrate success now! “Don’t wait to walk on the Moon to notice the thousand small victories that got you there. Rejoice in each new skill, every discovered idea, each small improvement you make in yourself. All the choices and ideas you list make sense. Do what is closest to your heart, the ones that make you the most excited. That way you are inevitably turning yourself into who you want to be.”
