- A new concept release about a relatively easy Earth-Mars Artificial Gravity cycler. The big fuel tank at the back is the OMT, or the orbital mega tanker of which I made a video about here: • SpaceX Orbital Mega Ta...
The artificial gravity modules are basically elongated (pun intended) Lunar Starships. They are lighter and the top part could be easily custom-made for this purpose.
Please tell us in the comments your ideas about future space concepts
Or what does not make sense about this one.
Disclaimer. The video is sped up by a few hundred percent to keep a good pace, to serve your short attention spans. The real spinning is at 2 RPM.

At some point, we will need a Mars cycler, which have to be assembled in orbit from inflatable habitation modules, launched by starships. After assembly and testing, a thermal nuclear tug must place it in Earth-Mars cycler orbit, so we will have a permanent cruise ship with plenty of passenger capacity and artificial gravity.
Would be cool if you illustrate this concept too.
YES
THIS
I only have this so far:

But Starship + Aldrin Cycler = The way
Very cool!
On the one hand it is a functional concept, on the other it raises the cost of going to Mars and adds complexity. It would be a luxury. Perhaps in the future this could be like buying a first class flight, while those who want to spend less will travel on a regular Starship.
Nice work anyway!
I agree with the portion of added complexity.
I do not agree that it would be a "luxury".
We will probably need some form of spin gravity for the trip to Mars in order to safeguard the health & performance of the crew during the trip.
The modularity of the concept is the most attractive aspect of it as we can build upon it over time.
(i.e: Send basic modules at first for the initial couple of voyages as we develop more complex modules for later expeditions.)
I think they produced of one of the best concept I saw so far everywhere.
Yea I see a lot of moving parts and structures too large to fit in a Starship cargo bay... :)
I prefer the LEGO Starships together option:

Build an Aldrin Cycler from custom Starships and carry groups of regular Starships to Mars in low-G..
The easiest concept is to string a long tether between two ships and set it rotating. The tether can be flexible since the artificial weight of the rotating ships will keep it taut. The rotation will be stopped shortly before reaching Mars and the two ships will be separated. A solar powered elevator could travel along the tether so that the two crews could interact.
Thanks for giving us an inspiring vision of what humanity is capable to do with current technology if we work hard and don't give up.
Many thanks from Brasil.
Interesting design, very good, very expandable too, to be able to add extra hubs/ships as time goes on. Before you know it you have a massive space station.
Oh wow!!!
Much better than the initial concept!
This might actually work IRL!
Amazing work guys!
that was so cool
nice animation. I like all these idea floating around. I think it will be something a bit simpler. Maybe with just a tether attaching two starships for some spin gravity.
And of what material? Even this wouldn't work, it would all break apart.
This is definitely a much more refined concept. Looks good.
Very cool. Nicely done!
One day, this vehicle could also help disassemble the ISS upon its program conclusion
Great video and great work for the editing.
I am glad that somebody realizes that you need a third stage for interplanetary missions! Do the cargo landers still need to reach Mars as a two-stage rocket? An orbital tanker only has about 150 t of propellants for transfer to another spacecraft.
Excelent option for artificial gravety
Yes! Perfect! This is exactly where I think we will be going. The Ships are far enough apart for 1g at less than 2rpm. Probably a 10% g difference between the top and bottom Starship floors but that's fine. This provides 1g on the long trips to/from Mars, or in indefinite length orbits. And it's adjustable down to Mars gravity as wanted. People on the tethered ships, and cargo and prop on the others. Gravity deprivation is just as dangerous as radiation - people die when re-entering Earth gravity after years in much less. The one thing I would add is a transport loop from tip to tip through the center, so people can transfer between ships or ships docked to the hub. Finally you call it a cycler but show it in Mars orbit. I think cyclers are great (in sets of 6+) but your tethered ships would work just fine on the usual Mars transit approach. Outstanding, thanks!
Wow. This is epic. Thanks
Happiness when i see there is a new video from this channel
Hey, if you ever want a guy to do a voice over just give me a shout, I think it could really help your videos
wow look at it go round and round around a round red ball
Nice CGI.
If SpaceX can keep the manned mission to Mars at 6 months, perhaps the cycler may not be needed.
Are you doing a video on the ion powered transport for the SLS?
Bad news, good news. First the bad news. To take up all the angular countermomentum it would have to, the short-radius flywheel we see at 2:22 would have to be very heavy.
Good news: (1) rocket propellant goes much faster than the periphery of a metal flywheel can go without breaking up, so spin-up with tangentially firing rockets will provide a big mass savings. (2) You save a lot of rocket propellant if the motors doing the tangential thrusting are not where the flywheel used to be but, rather, far out. (3) The starships already have far-out rocket motors. They're exactly where they need to be for this.
I would make the starships rotate singly, not in pairs. They would have a long furled tether in their noses, attached to the same lift points they are lifted by on the ground, and at the other end of this tether, ion thrusters and solar panels to power them.
Use the chemical rockets at the bottom to put on a 1-RPM end-over-end spin, so that the rocket's former bottom end becomes one of the two bottom ends it now has, each at ~0.03 gees. Into this weak g-field we now unfurl a few metres of the tether, so that the ion drive module hangs a few metres forward of the nose. We turn it on and start thrusting tangentially.
This would raise the spin above 1 RPM, but we don't want that. So we slowly pay more tether out, at just the slow rate that keeps the angular speed at 1 RPM while the moment of inertia increases. Soon we're, soon the cabin is, 894 metres down from the axis of rotation and pulling a full gee, and out the other way the ion drive is hanging much farther down from it, pulling about 4.8 gees.
This lets one Starship give itself gravity at the cost of about 21 percent of system mass in tether-plus-ion-drive-plus-solar-panels. But I think you'll find that's a lot smaller percentage than the flywheel would have taken.
Why unfold the panels before entering cruise stage? That just increases weight as it has to be be reinforced to withstand acceleration.
HILEMS IT'S LOONY CHRISEMS****8888****
I'm still a believer the "quicker", "logistic easier" and "safer" way to go to Mars, is to assemble in LEO a modular Spaceship, with habitat modules, and lander capsules dock on it. Being propelled with Nuclear engines reducing the voyage time and propellant boil off. Then landing propulsive on Mars with a compact capsule. Starship could have many issues, like being a "do it all", Spaceship plus lander. That could delay crew certification by NASA.
How do you get your nuclear material into orbit?
@@edibleapeman2 On nuclear rated rocket, ooh, they have just sent one away on today's "Lucy Mission"
Would you be willing to do some animations for improvements to the starship and booster production methods or other design elements like improved TPS and improved ship catching mechanisms?
I think there is already a youtube channel creating animations of the boca chica site developments. ua-cam.com/users/Spacex3DCreationEccentric You might find some animations that you are looking for there
So the unspun Starships are landers flying autonomously, and the spun compartments are for humans?
I like it. I'm not sure I prefer it over a simple tether connecting two Starships, but your concept is both beautiful and thrilling.
The elephant in the room is it takes too damn long to get to Mars. I don't know how far along the Russians are with their nuclear space tug concept, but I love the idea of cutting the trip time to 6 or 8 weeks. *That* would be immensely helpful.
With extra thermal protection it could be used for missions to Venus or Mercury.
Once again they starships have to rotate vertically because it’s how they are built 😭😭😭😭 but nice concept just turn the ship 90 degrees
Its awesome
Were the other ships unmanned?
yes. All the astronauts would be in the rotating habitats during the journey
Excellent concept. Artificial gravity is key to healthy humans on long duration trips. Fuel tanker, crew accommodations with artificial gravity, solar power, cargo transport, and orbit-to-land/land-to-orbit are all key building blocks. The starship may be adaptable enough to get all the pieces in place with one underlying architecture combined with "minor" modifications/additions.
I'm wondering how far off an engine might be that can provide a starship with long-term, constant thrust in the range of 8~9m/sec²?
Ion drive perhaps? Probably a little way off, but I think worth future consideration.
It would provide simulated gravity without rotation. Think of an office block with an engine in the basement pushing upwards. You could even have a swimming pool !
And while the 'gravity' would cease once the ship reached terminal velocity, that would likely be at a pretty high speed. Then you can strap everything down, turn the ship around and decelerate for a week or two (or until such a time as you want to accelerate again), then flip back around and resume the acceleration, therefore maintaining the gravity effect in either orientation. Repeat the process as often as required. The overall speed would like a wave graph (is in up and down), but providing the engine can provide enough thrust to maintain 8~9m/sec² in the 'upright' orientation, and -8~-9m/sec² in the reverse direction, then you could travel vast distances without the need (and problems) with rotationally simulated gravity.
The long burn X2, about face mid way. So much Sci-Fi. a worthy concept.
Is like a scifi movie
Look around everything seems to have a ref. to at least some Sci-Fi stories (movies, miee)
I got so many paperbacks steadily turning yellow at the edges.
WOW A BUTIFULL CONSEPT AND FULLY DOABULL BRILLIANT ABSALOTY!! WOW AGAIN!!AND KUDOS ON THE ANAMATION BRILIANT WORK!😱🥴✌💪👌
Thank you so much 😀
YAY
Nice notion.
very nice video you make it's very joyfull awsomeee creative love from Pakistan
Maybe instead of angling the pods forward to the motion of acceleration, have the pods angled over the Mega Tanker.
Yes that would also be possible. But I kind of like the look of the forward tilt
@@SpaceXvision Maybe you can get creative and give a special engine pod that could be attached to the propulsion area of the StarShips to give flexibility for flights around the system, as Musk wants it to do. However, methane can go only so far as to being produced on celestial bodies other than Mars.
Y'all making it way too complex with the independent spinning section. Just make the whole thing spin.
then it'll have to be aline the solar array while in planetary transient
WOW!!! Send this suggestion direct to Elon Musk!!!
The problem with this concept is that it's only one dimensional force acting on the starship.Our body fluids will feel comfortable only in one dimension only in this concept.If we turn our body fluids will also turn which causes problems.
We have a lot of data using centrifugal force as a means of gravity, both on Earth and by running around in a large diameter tube on past stations.

I HAD TO LOOK AT THIS AGAIN IT MADE ME CRY NOT SORROW// HAPPY .😉 ****8888****
Nice work! I think having two smaller moon landers for the trip is unnecessary. Just have two starships, would work better.
I get the feeling that this designer think the two different Starship's crew quarters are axially different, and he might be correct for all we know yet ;)
Было бы ещё круче если бы к большому ускорителю можно было бы прицепить грузовые модули и к 2 жилым модулям ещё 2 прицепить тогда можно было бы ещё больше груза и людей взять на марс.
Please make this or somthing similar so. While not as good as what science fiction ideally has, it will certainly help to keep our bodies more comfortable and in shape.
And to grow things, experiment, a one stop chocolate plant.......
Efecto dzhanibekov .
La nave hará giros muy complejos y no creo que la potencia inicial, por ser inicial y no continua, sirva para detener un giro inesperado.
WRONG LEGS BUT FANABULES NONE THE LESS****8888****
In one word, No
tbh i stopped caring. These concepts are cool i guess but lets actually wait to see star ship work. From the timeline weve seen it'll take a very long time to do what elon wants. We were told 2-3 months ago we'd see a orbital flight. Still waiting.
Plus theres no way 100 people will fly on star ship, i ''accident'' and spacex will be screwed.
You can show me whatever concepts people make up but i'd rather live in reality.
Engineering wise this is a complex inherently WEAK structural concept. Reflects a creator who has video skills presenting a video exercise that is a complete waste of time.
