SpaceX Starship artificial gravity opens up...
The concept of sending humans to Mars has been an exciting idea for decades, and Elon Musk and SpaceX's talented engineers are developing powerful Starships that making that happen!
However, this presents a number of challenges, not the least of which are the effects of prolonged exposure to radiation and microgravity.
And whereas there are many viable options for protecting crews from radiation, gravity remains a bit of a stumbling block.
But how exactly will the SpaceX Starship generate artificial gravity on long trips such as to Mars?
The answer will be revealed in today's episode as Elon Musk finally reveals artificial gravity Starship!

Didn't really learn anything new beyond watching 2001: A Space Odyssey.

What I really like about these videos is how long they go on repeating the same things without giving any information. At the very end it's always such a delightful surprise when they reveal that the information promised in the title is not in fact going to be revealed. Fool me once as they say...

It's probably been mentioned already in this feed but the artificial gravity problem was solved in the film 2001: A Space Odyssey and beautifully portrayed in the process.

Gravity: We don't even know what it is yet, so it'll be the centrifugal method.

Artificial gravity sounds like an amazing idea for extended Space journeys.

If the best part is no part, that contraption with two starships on it looks very complicated.
What's the absolute simplest way ? Just spin the starship - just fast enough so there is an up and a down - doesn't need to be 1g. Tests have been done on small rooms too..

The concept of creating centrifugal gravity has been tested on the ground - small scale. The main issue encountered was dizziness. Standing, walking, turning your head from side to side within that rotating device caused inner ear fluids -- responsible for our equilibrium (balance, etc.) -- to ebb and flow. Test subjects experienced nausea and a sense of being off-balance, or vertigo symptoms. The onset of these symptoms is taught in ground school to prospective aircraft pilots. They must trust their instruments rather than "flying by the seat of their pants". For a pilot to make flight corrections until they feel balanced could put the aircraft in an unrecoverable situation. Based on my casual observations of the small-scale artificial gravity tests, it seems to me that that the greater the circumference of the rotating device, the lower will be the effects on astronauts' equilibrium. Given the animation showing two starships with a rotational velocity at 31 m/s at a radius of 100m (328 ft) providing a sensation of 1 G (in the transcript, it sounded like the narrator stated, "one gram", where I think he meant 1 g or 1 gn?) where the rotational speed is 3 rotations per minute, PERHAPS this could work; but, I don't think it will completely eliminate off-balance feelings and nausea when moving about the ships. Tests already performed on a smaller scale indicated that the radius would have to be rather large to alleviate symptoms. If memory serves, liberal radius estimates put that radius to Earth size. Setting those estimates aside, there are other limitations to consider, as well. How fast can an object spin without tearing itself apart? What about how well fasteners & welded joints can hold; rotational mechanisms & gears; propellent management to start & stop rotations or fine tune rotation speed; gyroscopic shearing force (not sure what it's called??) on every part of the collapsed / rotating assembly during course corrections; etc. I'm sure there are a multitude of engineering and human challenges to solve. Just the same, I'm excited to see whether some flavor of artificial gravity is deployed during my lifetime. Go SpaceX!

You don't need 1G, you need 1 martian gravity.

The difference between Neil Armstrong and the first person to set foot on mars is that the former had at least a reasonable chance of survival.

We definitely need to be setting up systems - spin or tether - to create some form of mavity in space.

Nice spin on artificial gravity 👌. You got the right idea with the 3 to 2 rpm spin with the longer diameter

To develop artificial gravity is a must. Transferring fuel in LEO is going to be a real challenge. Maybe the development of artificial gravity in this procedure could aid transfer, and therefore aid artificial gravity use in long term space travel as well. I'm not a scientist of any description, but it's just a thought! 😎

Interesting, but the render looks over complicated with a rigid connecting structure.
Being a Sailor at heart,
I would suggest going to a stainless cable at the nose, and having attachment rings farther aft on each side.

This way you could "Bola" two or more ships, and with multiples rig them spaced with short cables farther aft to the afore mentioned attachment rings, to create circular array tension structures for flotillas.

Sending Lone Starships with humans, would be stupid and risky. if you could send several, and move humans in crisis situations to other ships...
This might be a good place for your inflatable tech, where you have opposing port and starboard hatches, so you could connect ship circles via inflated tubes at the airlocks for long voyages. which would be way nicer socially. and for access to cargo ship's supplies.
I would suggest all hatches be kept closed, except when in use as a safety precaution.

So, you might want to figure rotational speeds for 1g on larger diameters... and ways to connect such circular arrays into multiples, where you could interconnect dozens of ships en route. I suspect it would change the psychology, if passengers could wander in huge amounts of areas rather than being bottled up all the time, nose into arm pit...

Also would suggest the Navy Sweepers style cleaning routine, where everything is kept shipshape, to keep people busy, and promote heathy mentalities, and not allow Slobs to drag everybody down.

It will probably be awhile before theres any Cruise Ship Nobility going to Mars... its more likely to be a working passage.

With everybody having responsibilities. And a 24 hour watch on every ship.

And maybe even a SpaceX uniform would be nice? I suggest Blue-Green and Tan, the colors of our home planet.

Elon is the future of humanity. Most of his critics are get owned by his intelligence and willpower to achieve the unachievable.. ❤❤

@alphatech This was pure fluf. This would have been better titled as 'Why is generating artificial gravity important to long duration space flight'
Regardless if it's spaceX ESA or the Commies the practical solution allows that group to win the pole position in the duration race.
Many organizations and people have lots of ideas so you need to do a post on each one of those ideas.

The ultimate artificial gravity would be a ship that accelerates continuously at 1G for half the voyage, flips 180 then decelerates at 1G for the second half. Cutting travel time to a few days. We might be able in the future to achieve it with nuclear fusion engines

gravity on Earth, isn't like an unknown element, therefore it is possible, to create it with for example several Starships, but for now, it really seems to be the very expensive action!

What's needed in order to meet time constraints and to minimize complexity (thereby making it quicker and easier) is D-DAG...

Down and Dirty Artificial Gravity.

Nose-to-Nose Starships that are connected merely by a 100 meter long cable.

That's it.

Thrusters aboard each Starship take care of the rest. If computer controlled, the tension, direction of motion, starting and stopping can all be performed about as simply as spinning a Laso or yoyo over your head.

Multiple Starships could make the trip to and from Mars using a Cycler Ship at one time. Since the cycler is already in motion then only correction burns would be required saving fuel. The spin could ramp down from 1G to 1/3G for Mars crew/cargo drop off and spin up from 1/3G to 1G for Earth drop off.

Seems like a better idea is a simple tether that allows fuel transfer between two starships. The initial revolutions can be started with maneuvering thrusters, then once at 1G traditional transfer of fuel could allow them to balance the loads between the two starships.
