Nasa officially revealed how SpaceX will refuel Starships in LEO...
Refueling is bound to become one of SpaceX's most challenging missions in the years ahead, surpassing any mission they've undertaken before.
Nevertheless, SpaceX remains resolute in its determination to achieve yet another groundbreaking feat. Recently, both the company and NASA have meticulously outlined a clear roadmap and specific procedures for this ambitious mission.
So, how will this intricate process unfold? Join us as we delve into the details on today's episode of Great SpaceX.
Nasa officially revealed how SpaceX will refuel Starships in LEO...
Despite facing skepticism about the feasibility of the task, Elon Musk recently affirmed SpaceX's commitment to solving the challenges associated with refueling by the end of next year. He emphasized that refueling, alongside full and rapid reusability, is pivotal in realizing the vision of a multi-planetary existence.

Indeed, refueling will play a vital role in pushing the boundaries of exploration, with one of its primary applications being the upcoming Artemis 3 mission, where SpaceX aims to land humans on the Moon for the first time in over 50 years. Subsequently, refueling will also be indispensable for Starship's journey to Mars.

Best of luck to Starship and benedictions of creativity to all SpaceX engineers.
Yeah, let's wait for their next feats 👍
Ambitious considering they have yet to orbit starship successfully.
Even so, the only way to move liquids from tank to tank is by physically reducing the volume of the feeder tank. 'Pressure' doesn't do it, not in zeroG. Now, if you do it via ullage, that's not zeroG. Ullage will also change the orbit. They would be well advised to NOT use cryo fuels at all, to avoid boil off and overpressure issues with the storage tanks. Boil off establishes a ticking clock for any mission, something that would be good to avoid. Not using cryo fuels would allow the fuel tanks to be simple bladders, and that would work well with the pressure idea.
NASA should just let SpaceX do their thing and conquer problems as they are encountered. They should offer supplemental funding and personel, if required, and say thank you once the process is done in 1 year instead of 5 years.
Thanks Kevin!
A cryogenic cooler would help to keep the storage tank cooler and less pressure
2:04 wow he really said that ? :)
such a visionary
Space being cold should reduce boil off, ya would think?
@2:07: I doubt Albert Einstein said that..
and how does the heat shielding magically yet safely move aside to allow docking?
Think introduce a plunger system so so can keep 100% pressure in the tanks all the time.
SpaceX could launch multiple mini reusable tankers using Falcon rockets and “fillup” the Starship
Can one not use rotation to settle the fuel, rather than a thruster; using the excess vapor in the receiving tank? F. Miller
Shouldn't be any harder than automated space station docking, and even Russians can do that.
There will have to be a "depot" (modified Starship tanker parked in LEO) to be fueled about 200t at a time from tankers. The mission to Luna will take a Lot more fuel. Spacex indicated about 6 tankers to fuel the depot which can then fuel the Lunar Lander. I would expect that they would use 8 or so for safety. This is not a problem with more than a dozen spacecraft and 3 operational launch pads. There is currently an inventory of 16 Falcon 9s. I would expect about that many in inventory by the time 09/2026 rolls around (the month flagged for the lunar mission). Starfactory is near completion and has a (theoretical) capacity to build 100 starships per year (though that will ramp over several years and may not need to reach that tempo any time soon). (The Texas and CA Raptor factories should be scaling from 1/day to 5/day. Assuming only 1 Starship per month in the next two years, that's going to be a lot of ships that might be used as tankers.
Pressure differential will only 1/2 fuel the target. You need pumps. Shouldn't be a big deal.
Love the channel. Sup nerds!
♥️♥️♥️
I get lost in the bigness of your goals. ⭐♥️⭐
Do you think they achieve the fuel transfer in the tanks in the weightlessness of outer space without a baffle or a collapsible bladder?
We need to wait further updates to know this
@@colonbina1 Great Episode, Kev.
I don't think so. I think they might opt for an additional smaller fuel tank with higher pressures for refueling and reentry.
Can Tesla bot be used in testing?
Isn't such a rigid connection between two craft in space dangerous? Seems to me that any variances in orientation can cause the tiny margins to disappear, and such variance can be caused by malfunction in any of the maneuvering thrusters. Sure, spacecraft have docked one-another for a long while, but the dock is towards a narrow surface, reducing the effects of misalignments. In Starship's case, 50m of length have to perfectly align.
SpaceX has shown incredible feats, for sure, I just can't see the benefit over a hose that links the two craft.
We have been docking spacecraft through a "rigid connection" since the 1970's or Spacelab and very routine with ISS. What is the concern?
I just want to see flight 4
OK, so propellant will flow from high pressure to low pressure. But sooner or later the pressure will equalize and then, presumably, flow would cease, having transferred something much less than the chasers full fuel load. What am I missing here?
It's called a vacuum pump. I think starship will need to vacuum down its empty tank before fueling. The tanker then pumps fuel into starship then repressurizes the tank. I'm not a eengineer but sounds good to me.😂
@@daletroxel4649 Except SpaceX said they had no intention of using pumps.
So will the military version of Starship be called "Starship Trooper"? ;)
This plan doesn't sound feasible without major modifications. The fuel won't be homogenously distributed in the tank, so how control what ends up in the Target, and what remains for reentry?
Also, with a pressure based system, refueling would become more and more inefficient. Unless they use different Starship designs with higher pressures at later stages. But for that, separate fuel tanks would be necessary. It shouldn't be an issue to put a high pressure fuel tank in the compartment section.
But ideally, why not combine those approaches so that there's no fuel sloshing issue anymore by using separate tanks for separate stages? It doesn't add more complexity in terms of additional technology required, only in terms of managing fuel flow. It might also be beneficial to have fuel redundancies, just as with the engines.
How to get a more of comments? Say some nonsense in the video and just wait...
What happened to neuclear fuel used in space ...
Am I incorrect in thinking that only the second stage (landing back on Earth) needs protection from excessive high temperature? If so, why construct stage one (or for that matter the Moon landing version of stage two) using heavyweight stainless steel? The Moon landing version can either remain at the surface or be placed in Moon orbit. Construct stage one and the Moon landing stage two using carbon fiber. That way, surely the use of orbital refueling can be minimized (if not eliminated altogether).
Just using steel is way more practical, they dont have the expertise or equipment for something else and carbon fiber isnt light enouth to not refuel it if they changed the material of the lunar starship they could as well construct something completely new
I hope.. 💙
Hope what
I hope that spacex / nasa or China will build premises, a petrol station and eventually a factory in space as soon as possible, I'm in favor of expanding into space, but maybe in 20 years it will be possible to go somewhere safe...
I mean, space travel as an obligation, everyday, necessity... like a train ride from point a to point abcde and back
Howdy
Sokkal egyszerűbb a probléma, mint azt gondolnánk: A szállító tartályban, két csövön ellentétes irányban spirálozó áramlást kell létrehozni, és ezt megfelelő leválasztó edénybe vezetve a folyadék állapotú anyagot átszivattyúzni. Ez a művelet más szempontból is fontos, mert a keringetés a hőmérséklet kiegyenlítés miatt is szükséges. Ugyanez történik a fogadó tartályban is de ott a gáznemű fázist engedjük vissza a töltő tartályba.
The DEI cesspool that is NASA hasn't "revealed" jack squat.....
Why not just plug into the tanker use the fuel as needed then expend the empty tank? Is refuel even needed?
I think it's necessary to reach the Moon and Mars
Refueling is very necessary for reaching the moon and beyond, because they want to have a smaller starship that isn't too heavy for lift off and for price, and re-usability
Edit: so if the rocket is too heavy they will need stronger boosters which they will need to be able to handle that much heat so they won't explode I believe, which don't quote me on this but I think that's what the heat shield is used for, also increasing overall price
Too make your youtube video better, you need to research if SpaceX will take advantage of the movement of the center of gravity of two connected bodies and/or when one body disconnect from another toward it path to the Moon or Mars. In fact, just being in orbit could be dangerous; where the benefits of being on a trajectory to the Starship's destination could save fuel. Another fact is what about non pressurize system using non pressurize centrifugal pump since transfer of water could be important for future mission. PS Pressurize fuel transfer pump are usually piston base pump like when you fill up your tire with air. I would suggest they first test setting up a circular pumping of from one ship to the other and back. Once this is establish, a value will be shut and all the fuel will remain with the recipient rocket. This would negate movement of slushing which is associated with liquid fuel. Then the rocket undock. Regular Ocean Ship like the US NAVY do fuel transfers.
oh look the editor guy showed up today ... kudos sir but it's not as much fun with you here ... js
I don't think the Albert Einstein quote at 2:05 is quite correct
Refuelling might not be the biggest problem, but the dry mass of starship. It's too heavy.
Can you tell more detail about that?
@@colonbina1 Sure, since Starship isn't staging or refuelling after leaving LEO (at least not for now), its dry mass must be extremely small (below 100 metric tonnes) in order to fly the full HLS mission. That might turn out to be more challenging than the refilling.
@@odril The plan IS for starship to refuel.. complaining they can't do it without refuelling is ridiculous
@@paulslund1 Of course, the dry mass challenge exists WITH refuelling in LEO. Starship has almost NO propellant left without refuelling in LEO, so it is basically a dead brick. After refuelling in LEO, the full HLS mission still needs EXTREMELY low dry masses (
@@odril "I can help SpaceX with some consultancy, if they want to make it work. Elon has my number."
I'm quite certain his team has this already figured out.
Looks like soon..spacex super chargers..out there.or ,,,gas stations,,,😂
Why am i always first?
Thanks for your great support 🏅. Keep following and discussing our channel
@@colonbina1 okkkk nigga
Huh
2026? You have got to be kidding 😂. More like 2036.
MIND GAME MR Musk test me
\Z|NM,
Super Mexico X will become number 1 terrorist then escape to Mars without pentagon
😂😂😂
8-20X refueling is complex and nonsense for single trip.
If elon want 1000 starship go to mars , they need 20.000X refueling in space.
Why dont just inventing new kind of fuel?
Great question👍
Yes! A new propulsion system is needed.
@@ludwigvanzappa9548 in opinion elon biggest mistake is ditching hydrogen and use methane instead. I know hydrogen is expensive and hard to keep but hydrogen has 150 megajoule/kg energy compare methane is around 50 megajoule per kg.
For low orbital flight , metahe is good cause it is so cheap. But for long trip like moon and mars. Hydrogen is work, apolo 11 prove it.
@@colonbina1 elon is ditching hydrogen with 3 times more energy than methane. I think that is huge mistake!
@@kusumayogi7956
The point of starship is cheap travel to space so
to make hydrogen cheap enough it must be produced from nuclear powered electrolysis plants
Starship will never get those transfers to work. That ridiculous rocket will never go to the Moon or Mars.
People who are saying it can not be done should not interfere wih people who are actually doni g it. Think positive get a life hate gets us nowhere!!
@@harrystofberg5794
8-20X refueling in spacr for single trip is BS
True 8-20x refueling in space for single trip is BS
@@harrystofberg5794People can have their own opinion and express them if they want.
Having a different opinion doesn't mean hate...
And that stupid rocket will prove to be useless very soon. I don't give it two years.
@@kusumayogi7956This is where it will stop for Starship.
