Today something a little different for a change. So many of you ask me to talk more about artificial gravity systems. Up until now with the cost of mass to orbit being so high, it always seemed like something that was incredibly far down the track. With Starship soon being able to shoot massive components to orbit at super low cost, this kind of changes the game at that point. Ideas that seemed absurd, almost look to become plausible if you can send stuff to orbit orders of magnitude cheaper than we can right now. But why do this? And is it really as critical as others make it out to be? You might be surprised.

Have a great week everyone! For those interested in the presented Curiosity Stream episode, you can check it out at Curiosity Stream at https://curiositystream.com/marcushouse
If you already have it, the direct link to the episode is https://curiositystream.com/video/2998
Thanks!
I for one hate to see the weekly update videos sacrificed for other content, even on weeks where it may seem like not much went on.
The service of weekly documentation almost serves as a historical record that ends up with gaps if the channel redirects its resources in other directions.
Nice video! Interesting to see these concept designs. I prefer the term "spin gravity" over "artificial gravity" because it is more technically descriptive and has less magic sci-fi connotation.
Pure CGI… just ask yourself why there's always CGI when they talk "space" and satellites… they are playing with your imagination after hollywood indoctrinated you to think that way… you never see one of the 45.000 satellites "in orbit" when actor-nauts are doing their "spacewalks"… they "say" they "can" photograph Saturn, but all "earth"'s pictures are composite images… one must wonder why they always forget to put a camera in the rear mirror and send us ONE picture, but also just do a little research and you might discover 99% of our world communication goes by underwater cables… and then add the moon technology and tapes destroyed… and that might be enough to realize: you have been fooled. Fool me once…
Gravity doesn't exist… it is differential density. Science cannot explain gravity… and when they do for the "planet" earth and the "moon", it doesn't hold the same principles for a helium balloon in you living room. Wake up, people.
Well, after watching that debate, Mark Kelly's brain damage is obvious. So yeah, get to work on the gravity plates.
Oh, how fantastic a concept from Nasa. So, it will cost 500 trillion Dollars and be available in 3976 if all goes to plan. Nasa has done more to stop Space travel and anything else in human history.
this tech will be more relevant when our robots get better.
How would you course correct any of the ships with spinning masses along their axis of travel? Won't they break up under the resulting gyroscopic effect? I think these ships fly well in CGI animation and movies.
This is the only fan leaning channel that has twice shown how Starship is not going to be the ship people take to Mars. "Starship" would have been named correctly if they called it "Star-barge". It's a supply ship. They are shoe horning it to be a Lunar lander, but that's about it.
great job as always thank you
i have a working concept for artifical gravity, and i have no ability to show it to some real engineers that is actualy doing this.. simple ring wont work. I mean it will work, but i have a concept that you wont feel any centrifugal forces 🙂 you also wont feel dizzy. Its really simple solution, solution is similar to diferencial. Only the other way around.
more troubles yet if you leave earth's magnetic field that protects ISS. two cable tethered ships is sufficient for "artificial gravity" (3 cables surrounded with a fabric inflated atmosphere tube) or (one cable and a very light cable car) (with a heated, insulated, water hose between to keep the two balanced with water as ballast)
I THINK I HAVE SAID IT BEFORE INER SHEL THAT SPINS OUTER STAYS STILL, NOT HARD
IF I HAVE MONY ILL PUT SOME IN ,YESSS****8888****
WHERE THE NUKLIAR I NEEED TO LERN, LOL ***8888***
it's not crucial to have gravity for the 8 month trip to Mars
Like the strange rotating asteroid amoamoa or whatever its called, flip or spin the ship. The length of Starship should allow the nose section and whoever's in it to encounter G-force.
19:00 yea the question is why not youre right we have had over 50 years to do it.
Cost will be irrelevant compared to livability and time. I have an over-simplified idea for dealing with space sickness. How about a mirrored shield contolled by a computer eliminating the Spin-cycle perception of gravity induction. I've not heard ANYTHING about how we deal with anti-gravity issues if our vision's impact can be dealt with. Our eyes look in one direction at a time, if we can artificvally manipulate that, could our bodies overcome the antigravity issues we're fighting now? We're probably going to be wearing a helmet anyway.
I once was a fan of Elon Musk, Tesla, Space X, Star Link, but no more! Not after the Musk statement that we should honor the election at the point of a gun in Ukraine. There is NO excuse for this type of statement! Musk’s statement ignores the fact that there have been terrible war crimes perpetrated on the Ukrainian people, it ignores the naked aggression of Vladimir Putin. Putin’s indiscriminate bombing of the civilian population is inexcusable. It’s sad because Mr. Musk started out so well providing Star Link dishes to Ukraine then completely reversed his thinking. There are times that one needs to stand up to bullies and this is one of them. Mr. Musk, to be sure, is an excellent engineer, but when it comes to forging affairs, HE IS A WET SOCK PUPET! Furthermore, apparently, Musk does not understand the difference between free speech and disseminating disinformation and propaganda.
Would artificial gravity cause the coriolis effect?
Yes to cosmic radiation videos!
Excellent like always.
Instead of a typical space station design, why not simply tether two Starships together with a high-strength cable? They could even be a kilometer away from each other, eliminating the problems from the Coriolis effect. With that distance, they wouldn’t need to rotate quickly.
There are strong, light weight ropes like Kevlar that should work. There is no need for a major construction project in space to assemble the big structure of other designs. It’s simple, and far less expensive, only requiring two launches.
This would work while traveling to Mars. When you get there, simply disconnect the tether before landing.
u r awesome man
Wouldn't it make more sense to accelerate to Mars at Mars Gravity equivalence, then the People onboard will be acclimatised to Mars"G"?
What in pretty near all of those provides the contra-rotation, you know like the Defiant SB-1?
would we need to have a full 1.0G of simulated gravity for a trip to and back from Mars, like whats the minimum that would prevent health detrioration?
👍
What a terrific and helpful effort, Marcus House! You concluded with the right question (having underscored the damaging effects of microgravity early on), which is this: Why, after all the decades we've been travelling to space, have we not done experiments to see how well humans could withstand the lower gravitational force that they would find on the Moon and Mars (if they were on the surface months or years at a time).
Once again, thank you.
what happens to the bodsy when subjected to slightly increased gravity say 1.2 g for extended periods. I really hope the answer is we get super strong and not we end up about 2 feet tall lol
Gravity isn’t just a problem while traveling through space , it’s problem on places like the moon and mars where lack of earth like gravity and earth’s protective shield will have very negative consequences for the human body especially for long term stays .
The Gateway Spaceport is a not-so-near future concept, envisioned by the Orbital Assembly Corporation, a.k.a. OAC. They're already working on the machines for building a small-scale prototype. It's expected to start construction in a few years 🙂
1g acceleration to mars followed by days of deceleration once mars orbit is achieved
what about weighted suits for use on mars? surely one third gravity is bad for humans too. so design space suits to weight around 120kg.
The only problem with rotating objects in space is the Dzhanibekov Effect. This would apply to any spinning object in space with uneven loads. Alot of testing will need to be done to make sure this issue is eliminated.
No it is not; Dude chill out it is only 7 months and they are heading to gravity that is one third of Earth's. I'm quite Certain that NASA and SpaceX know alot more than you about this, and absolutely nobody is building such a craft for Martian transport. Even ISS missions have lasted alot longer; up to 355 days, and everyone is just fine.
19:22 "it's always seemed bizarre…" we haven't tested living in low artificial gravity in space. YES! Thank you! AT LEAST some small mammal tests if a human habitat would be too expensive (sorry, mice).
Marcus, just a quick note that I have nothing but praise for your channel, but I am temporarily unsubscribing simply because I am so furious at Elon Musk right now re Starlink and Ukraine that I dont want to hear a damned thing about SpaceX for a while. I'm old and in poor health, and getting wound up unecessarily isn't good for me. I'll be back as a subscriber as soon as I can!
Biological humans are horrible at space flight. You have suspend animation, disembody brains, or digital copies of human minds. All eliminating the need for artificial gravity. Yet it's fund to imagin such artificial gravity system, even if it will have limited use in the long term.
