One MAJOR problem with people living for a prolonged time on moon and Mars is GRAVITY DEPRIVATION which is even worse on the moon but with the tradeoff of it being easier to get back to Earth. Zero G ruins the health of astronauts and would probably be fatal in less than 2 years since the world's record is 14 months and his health was god awful when he came back to Earth. Moon and Mars have better than zero G so the gradual damage to the body would not be AS bad as in space but over time the lack of 1G of gravity would gradually ruin people's health. The human body needs close to 1G of gravity to be healthy.
At 16:50 the commenters state that rendezvous is really hard. I'm not sure I understand the context of the statement. Earth orbit rendezvous was perfected during the Gemini program. That was one of its goals, as a proof of concept for Apollo which utilized lunar orbit rendezvous. Rendezvous was in integral part of the Apollo program and has been used in the Skylab, Mir, and ISS programs. The crew ferrying as well as cargo resupply missions all utilize rendezvous to get astronauts, cargo and cosmonauts to and from the ISS. Spacex's Cargo and Crew Dragon vehicles perform these maneuvers with a high level of autonomy. Perhaps I didn't understand the context of what was being said, but rendezvous has been effectively utilized since Gemini VI and Gemini VII. Ok, technically Gemini VI-A. Perhaps they were referring to building large structures in space. But then the ISS was assembled in space using rendezvous techniques. The space shuttle hauled ISS modules into LEO and then rendezvoused with the growing assembly and the modules were docked together. So the statement, "rendezvous is hard" seems baffling to me as we have been doing it since 1960s.
13:00 not quite into this yet but, asteroid mining - okay we find an asteroid rich in X and we want X, we go get it, but the problem then is, extinction events, we either bring it back to earth in tiny bits or do something with it in space, which might be combined with space stations - if we set up mining stations around earth and the moon and mars, that might be a way to do two things at once.
Colonization is an exciting idea that attracts public interest but seems like pure fantasy in terms of scientific and engineering practicalities. As was mentioned in the podcast, no amount of damage to Earth will make colonizing the moon or Mars better or easier than just employing the same techniques on this planet (e.g., underground cities). I wish we could terraform Mars or another planet for the sole purpose of providing a home for all the nonhuman species on Earth who are being crowded out of existence by the invasive and destructive H. sapiens.
i can get behind the excitement, i love space travel, it's my eardrums are wondering why kelly is shouting, does she think she's talking in moon atmosphere.
1903 - first manned airplane 1957 - satellites 1961 - humans in space 1969 - humans walk on the moon 1971 - space stations There's never been a point in the past 23 years when there wasn't a human living in space. If we don't destroy our civilization with nuclear war, it's only a matter of time.
What a TRIUMPH!
This was the most fun episode of Mindscape ever and yet absolutely packed with intriguing ideas.
No book has conflated difficult with can't more than this one.

So exciting! One day I hope there is some panel that Sean, Randall, and these two can be a part of together.
Sean wins the Internet with this episode!
That was fun. I listened to this at the dog food factory with my ear pod's in. Brilliant 👏
In the past week I did a marathon of your ''biggest ideas in the universe''.
WAS LOT OF FUN!
Caves.
Caves on the moon, caves on Mars.
Caves are neat.

Loving the thumbnail!
i loved this talk definitly one of my fav podcasts ever fascinating topic 🙏👍
thank you~ superb ,take it easy.
space is "like... you know..."
interesting topic. AND good video for a drinking game.
Checkout "Where the Winds Sleep" by Neil P. Ruzic
SMBC has been a great comic for years... one of the very few I read

Loving it
building a hotel for the rich, maybe... but it needs to start with something.
Alone don't count and a non-zero chance it was Shatner.
Why so excitable😂
Like talking too a teenager after 3 red bulls
i can get behind the excitement, i love space travel, it's my eardrums are wondering why kelly is shouting, does she think she's talking in moon atmosphere.
I think rocket fuels will be the real bottleneck. You need to not speak in dollars. Cost is energy.
was this a shouting competition?
No, a humour and enthusiasm one
can we have at least _one_ spaceship called "serenity"?
… as a German Biologist…
we destroy the Bio Sphere here
ends nuclear
Dreams and Delusions
Yea I'm 1st☺
nah, neil was first.
Watch the movie “Moon” you won’t be disappointed
I love you Dr. Carroll, but this is akin to planning a move to Barsoom. Utter nonsense.
I think humanity will battle inhospitable environments as long as there's profit to be made.
1903 - first manned airplane
1957 - satellites
1961 - humans in space
1969 - humans walk on the moon
1971 - space stations

Wow. I was expecting that to be fun, but the guy was too annoying, I had to stop listening.
Interesting...though could really do without the snide, but overtly political, comments about Musk/X.
Too comedic and "fun" for me. Found it irritating. Podcasts with > 1 guests always turn into this. -1
Normally I agree but here I liked it.
You must fun at parties. 😏
@nabormendonca5742 just not my style for an informative podcast. I like all the other ones.
Irritating is proper description for this episode.
