Elon Musk Reveals HUGE Solution for Starship Heat Tile! Flight 5 Launch Schedule...
Clearly, SpaceX's Starship is facing challenges with its heat shield, particularly the heat-dissipating tiles that protect it during reentry. However, with Elon Musk's determined attitude, he certainly won't let this hinder his ambitions. Recently, Elon Musk revealed impressive technical solutions to address the heat shield issue.
Let’s find out on today’s episode of Alpha Tech: How did Elon Musk SpaceX fix the Starship heat shield and re-entry?
Elon Musk Reveals HUGE Solution for Starship Heat Tile! Flight 5 Launch Schedule...
In engineering, a heat shield is a component designed to protect an object or operator from burning or overheating by dissipating, reflecting, or absorbing heat. Therefore, no spacecraft can re-enter Earth's atmosphere without a heat shield. It is also a crucial component of SpaceX and Elon Musk's ambition of fully reusable rockets.
With the impressive performance in the fourth launch, we observed instability with the heat shields, specifically a weak point between the flap and the main body of the Starship. This vulnerability nearly compromised the spacecraft, as the intense heat during re-entry caused considerable damage to the flap. Despite this, Starship remarkably managed to complete its landing burn with the flap still functioning, demonstrating the spacecraft's robust design and resilience.
Elon Musk Reveals HUGE Solution for Starship Heat Tile! Flight 5 Launch Schedule...
But not to keep us worried about the issue of heat shields for long, SpaceX and Elon Musk have been striving to improve the heat shielding capabilities of their reusable Starship.
And indeed, they are being carried out right on Ship 30 in preparation for the launch of Starship Flight 5.
The first solution proposed by SpaceX and Elon Musk is to replace the entire heat shield with new tiles that are twice as durable as the previous ones.
“We have to take, we're gonna replace the whole heat shield on the ship. So the new heat shield tile is about twice as strong as the ones that were on the last flight,” shared Musk.
The new tiles are “about twice as strong, or hopefully half as likely to crack or come off.”

[@arnoldlueders7500]

I am very confused because SpaceX released that they put the missing tiles in a non-critical area near the skirt so that if there was a problem it would have only affected the outer engine which was not needed in re-entry and hovering

[@BustaCap]

Why don’t they mold the vehicle with the heat shield. Like 3 massive pieces that are reinforced.

[@sophiegrisom]

An "abrasive layer" would be bad. You likely meant "ablative layer", but kept saying "abrasive". In general, higher temp materials are more brittle and thus less "strong". By "stronger" did you mean better thermal resistance or better structural properties? If an ablative layer was used, the thermal protection would have to be replaced after a re-entry.

If the ablative material is like a thick mattered coating under tiles covering the whole endangered area smearing an outer coat on top of the tiles could give a bonding binding coat that would triple the danger of any tiles being sucked off at re-entry. Extra shaping around flap joints to deflect forces and flow would be logical as a moulded lip up and away at the edges of tiles around body

The solution to the flat heat tiles is to make each heat tile into an individual dome. The dome will allow the heat to be layered with the hottest temperatures at the top of the dome and the low temperatures where the tile is attached to the skin of the metal. You are welcome.

[@keithmcdonnell4485]

02:35 Ablative layer, not abrasive layer. Four min in and the mistakes just keep coming. Not going to watch the rest. Junk info is worse than no info.

[@guypehaim1080]

I think that, with the Starship's refuel ability, using its rocket engines to retro into the atmosphere, it can be slowed down enough to allow it to return to the surface of the Earth without the use of a heat shield. If it can leave the Earth without the need of a heat shield, it doesn't need it coming back.

[@petecomps7260]

The "thinner" tile on IFT4 was an ablative tile. The experiment wanted to determine how well it performed when the outer ceramic tile is lost.

[@stevelacroix2917]

Maybe we need to rethink re-entry entirely. Maybe a dip down, pull up method would allow the ship to slow down, albeit slower, and then literally drop out of orbit based on a significantly slower re-entry speeds. Imagine if the re-entry took multiple orbits, instead of just one. Thoughts?

[@djohannsson8268]

Apollo used a combination of re-entry techniques, to reduce their re-entry speed. First descending using their ablative shield then attempting to climbing back up without power to reduce speed. This works but takes more re-entry time. Using acs thrusters to change the descent and attack angle.

[@yoyo-jc5qg]

yep i think in the future they'll use the heat generated during descent to power thrusters which slow the vehicle, but like u said it'll take a lot longer to land

[@ericvdavies]

I suggest the tiles must be given some racks made of metals or alloys which can with stand the temperatures of re-entry and further more increasing the efficacy of the adhesive used initially

[@2atalkandpolitics422]

Umm the spots where tiles were missing were said to be where a compromise wouldn’t occur per Elon. The ablative material may be bad for reusability but it I think it’s a stop gap measure till Elon can make a more permanent solution

[@razmop]

Why not cover the entire ship in heat tiles and then as it comes into the re-entry phase roll the ship on its axis and thereby distribute the heat over the whole ship?

You would have to be there to record it.

[@michaelharmon5991]

He did not say the new tiles are twice as insulating, he said twice as strong. It is entirely possible that the new tiles are more conductive, rather than more insulating due to increased density which would be the normal specification for ceramic insulating materials. I think you are misleading people saying the new tiles will tolerate 5200 degrees F. I've never heard of tiles that would handle that temperature. While I'm not a rocket scientist I am a foundry engineer with 50 years of experience so I know a thing or two about refractories.

[@petergibson2318]

Assume a tile falls off. What's to stop the ablating (melting and evaporating) material melting the material under a "good" tile beside the location? I can see whole strips of tiles peeling away because the material underneath each tile in turn has started ablating...allowing superheated and supersonic gasses to burrow UNDER the "good" tiles.

[@tbix1963]

Ablative, Abrasive. 😂 It must sand off the heat.

[@eeman1335]

Question I would ask, is if this secondary layer of heat protection that slowly burns off, could it build up and jam the hinge of the Starship flap preventing it from full motion?

[@ricksterling6322]

I am a laymen, while I don't understand the science of it, I am fascinated by it. If the boosters don't have heat shields and do a reentry burn, why doesn't starship do a reentry burn without tiles?

[@youjustdontgetit8117]

Starship goes higher!!! Different processes

[@KennethHartsell]

The booster only goes up to the edge of space while starship goes a bit higher and more importantly, much faster. If starship did a big re-entry burn and cancel most of it's speed prior to encountering the atmosphere then yes, it could do without a heat shield. The direct answer to your question is fuel is a limited resource and using air to slow down is basically free.

[@martin.legarda-guia]

a lot less speed

[@charlesmaurer6214]

Added though to finish firing tiles by reentry itself to save energy the launch site itself could serve as a kiln of sorts to reclaim some of the heat of launch for a productive use even if it is just a finish glaze on commercial tile or brick to be sold for the public. Due to the short firing time and cooling after it would either be a tempered or crackled glaze, suitable for either fireplaces or decorative aged look. Could also create a blackened look with unglazed material absorbing the carbon.

[@barryhoneycutt3894]

[@LG-qz8om]

Natural phenomenon. When one doesn't know the definition of a word that word goes blank. Abrassive "causing friction" Ablative "burns or flakes off with heat or friction" If i were to guess the Misunderstood Word is "ablative" which is why he keeps using another common word instead. Anyone can be found to have many common Misunderstood words. Even college professors. PS: abrasive would cause more friction and thus more heat. BAD. Ablative is used because while it may get hot when it flakes away it takes with it all that extra heat. GOOD.

[@alphatech4966]

Thank you for your comment! I will fix this

[@charlesmaurer6214]

Related but alternate thought. I took ceramics in school and all are produced by heating the raw mixture, normally at least twice to gain final properties. To save energy and to reduce the brittle factor during lift off I wonder if it would be possible to actually use the heat of reentry to give the tiles their final firing. Perhaps in secondary areas, also might send spares equal to double the avg lost to be installed with a spacewalk if needed. Might add partial fired tiles to an upper stage booster that will receive enough heat or as an extra row or two. I don't know the exact specs for the tiles or the mix to make them, I could also see a final glaze layer that finishes on reentry reducing friction with a partial ablative cooling property as well. Like a layer of paint that melts turning part into a glassy surface and releasing evaporative carrier material that melts then evaporates like sweat.

[@duran9664]

❌Trapping ourselves in yet another gravity trap (moon, mars…) is just pure insanity🤦‍♀️ We must only focus on building our own planets (aka spaceship). Must should send thousands of rockets to assemble gigantic space ships in space.

[@repalmore]

Have to correct you one thing. Heat Shields are only necessary for aero breaking. Some might contend that we have the tech to slow down before entering the atmosphere. I don't know if this is true but obviously it is the most cost effective way to slow down now.

[@catsupchutney]

There will be a LOT more heat generated from a lunar orbit re-entry.

[@DennisMurphey]

I don't understand why they want to be a ablatable material behind the main tiles. Seems to me the ablatable layer should be external on easily removable mounts that are exchanged on every flight as a routine. Then keep the hard tiles affixed with only slight use on every flight. This method would ensure the ship remains intact with all possible failures. And on the flap joints why not mount the same ablatable material on the joint overlapping but still allowing flats to move free. Then simply remove and replace as a matter of Standard Operating Procedure. Dennis

Despite what the title suggests, the second layer being tested on IFT5 will not address the fins. That will _not_ happen until the Block 2 vehicles arrive. The ablative layer by itself simply will not be able to prevent the fins from being damaged again. It is going to happen again, and SpaceX knows this. Be patient and wait for Block 2 with the fins moved away from the ship's belly.

[@-OICU812-]

This is what I was thinking. It will take an adjustment to the design to make those changes, and in the meantime, they can still learn a lot with the ships that are available. There are still plenty of things for them to learn. I don't remember how many ship bodies are past the point of them being easily able to reconfigure, but I am looking forward to seeing what the Block 2 vehicles will look like.

[@Asterra2]

@@-OICU812- It's either just Ship 30 or one more Block 1 vehicle, which they may decide to go ahead and skip, since it would quite arguably be a waste to put another Block 1 vehicle through its paces-spin prime; static fire; WDR-when it will still be guaranteed to partly melt on the way back. The first Block 2 vehicle is already being made. The counterargument to this is that SpaceX currently has a fast track to licenses as long as they stick with the current flight plan, and so may in fact decide to send all their Block 1s through the blender as sacrificial lambs so they can knock out the jobs of in-flight burn and true orbital insertion in quick order.

@@Asterra2 Do I understand it right that there is zero recovery for any of these launch vehicles? Is there nothing they can learn from inspecting what remains of these units after splash-down? It seems like they should be pretty much whole, or whole enough to see where they may make improvements or even areas where they may not need much improvement at all if any. It kind of seems like a waisted opportunity, especially if they have vessels as close as they seemed to have on this flight.

@@-OICU812- Believe it or not, the sensors and cameras tell a pretty complete picture. Consider for example the fact that Ship 29 had two tiles removed and a third replaced by their new ablative layer by itself. Evidently, whatever sensors they placed in those areas were adequate to provide SpaceX with all the data they wanted. Anyway, I don't think SpaceX possesses the hardware to actually recover something as large as Starship or Super Heavy Booster. Leastwise in the middle of the Indian Ocean in the dead of night.

The ceramic tiles and the oblative material will need to have some way to move to accommodate the thermal shrinkage and expansion of the steel. So the oblative material must also be cut into tiles. Most likely one will be offset above the other so they overlap and there is no direct path to the softer white thermal mat below.

I have concerns regarding the shape of Starship and the use of ablative material beneath the heat tiles. The NASA Space Shuttle's "Arrowhead" design provided a broad area for heat dissipation and flight control post-re-entry. Control surfaces, especially their hinges, are highly vulnerable to high-temperature gassing during re-entry. Deflecting these gases before they contact the hinges could significantly mitigate this issue. Modifying Starship's underside to be slightly flatter might help deflect the plasma that forms under the ship as it uses the atmosphere to slow its descent. The current cylindrical shape may funnel gases into the creases of the control flaps, while a flatter underside could better protect these areas. The ablative shield's placement beneath the primary tiles also raises concerns. Leaving the ablative shield in place could cause degradation of the outer tiles and their reusability, but if the external tiles must be removed after each flight to replace the ablative shield, there could be great costs incured and the ship loses some of the value of its reusability. I also have questions about the stability of the tile structure as the ablative shield undergoes heating and cooling with each re-entry. If the ablative shield shrinks and expands during each re-entry, the tiles will undoubtedly have stress exerted upon them causing openings to form and allowing these high temperature gasses several points of entry. While the concept of a reusable ship is commendable, the complexities involved may necessitate changes to the original plans. Given the cost of test launches, any necessary modifications should be implemented swiftly. I truley appreciate the efforts of the program, and you guys have an excellent video here. I definitely don't want to discourage the efforts made by Space-X, but an opinion was asked for so here it is.

[@-OICU812-]

@@JohnUrbanic-m3q Not you obviously. Have a nice day!

[@Asterra2]

I think you're misunderstanding the game plan going forward. The ablative layer is going to serve two purposes. Right now, tiles are still falling with every launch. SpaceX nonetheless wishes to reach a point where they can have Starship reliably survive reentry. A missing tile in a critical spot, which is actually most of the hull, would kill the vehicle. The ablative layer is being used as a bandaid for now. It truly ought to prevent missing tiles from dooming the vehicle. Fast forward to when tiles are only falling off once in a while (like how it was on the shuttle) and the layer is the safeguard against certain doom instead of being a bandaid against almost guaranteed tile loss. Your refurbishment concerns will be essentially moot at this point, as they won't need to tend to the ablative layer all that often. When they do, they're not going to replace the entire thing, nor will they need to remove extra tiles. Cut out a hexagon, replace it with new ablative material, replace the tile. Simple as that.

[@-OICU812-]

@@Asterra2 I guess I missed the part where this is a temporary fix with the ablative shield. I totally get that it will take a lot of testing though.

I have a question. What if there were no flaps? Elon said it best, the best part is no part, I personally feel like significantly more thrusters could control all directional changes. He talked about adding thrusters in the Everyday Astronaut interview. Why not make them more plentiful, powerful, on the back spine of the starships, at about 105 degrees apart, and do away with all the flaps and extra weight, hinges, tiles, motors, batteries I mean, if this could be pulled off it would be a huge win.

[@eldarshamukhamedov4521]

Flaps and the whole "belly flop" maneuver is meant to save fuel, compared to other solutions. Starship re-enters at orbital velocities, so a lot of the things that worked for boosters (Falcon and Starship booster) won't necessarily work for Starship. You'd need to burn a lot of fuel just to drop velocity enough to get back to booster re-entry speeds. So flaps/belly flop are how SpaceX saves a lot of re-entry fuel and keeps payload to orbit high.

[@kidcasco1966]

[@alphatech4966]

Oh! I will note this!

[@Max-xl9qv]

Sounds like ablative shielding and beefier tiles adds more weight to a system that is already too heavy. For launch systems that leave earth orbit or even go geostationary, two stages don't work without refueling. Good luck bringing up 1200t of propellant for StarShip in 100-200t increments per flight.

[@avgjoe5969]

"Already too heavy?" Musk already addressed this. V2 is slated for 100t capacity and is already under construction. V3 will have 200t capacity and is the version that will land on the moon. The tiles are estimated at 300gm to 1kg each putting their weight to 18 tons at the worst. The throw weight of V2 is 100t including the current set. Making them thicker might add 5 tons... with a 95t cargo capacity as a result in the worst case. From V3, this increases to 200t... so maybe 190t in the worst case. I don't think you did the math. Also, what is the big deal in bringing the fuel up in 6-7 flights?... or 8 for that matter. They have already mastered docking, rapid production of ships, cost effective production of ships and merely need to put up a Slightly modified tanker to act as a Depot. 1 Lander at $300m (Elon estimated standard ships cost $100m), 1 depot at $100m, let's say 8x $20m for 8 reusable tanker flights...($160m). The lander flight might cost - $560m? Compare that to SLS/Orion at $4500m. People keep saying multiple tankers is a bad thing... with no big obstacle to point to. One went on to say "if you lose even One tanker"... what? It would affect nothing. Losing 1 or even 2 tankers would be a hiccup by 09/26 with the massive new factory completed, New engine factory completed, massive new revenue ramping from Starlink... all the pieces are falling into place Well before 09/26. They can build a dozen (reusable) tankers if they want to in the timeframe and budget. In orbit refueling is Critical if we want to send any useful tonnage off world to Actually build a Useful moon base. One that can eventually support itself. We can't keep "exploring" at great expense. We need to colonize and make space make money for investors. Can't do that without orbital refueling.

I guess SpaceX didn’t do the math and only discovered recently that it won’t work like envisioned because it is too heavy or lacks the power for reasonable missions beyond LEO without refueling in orbit, and the latest numbers from the tests have shown that with the current system a ridiculous amount of fuel flights is required - in the order of 20 for a single lunar mission. So now again a bigger rocket is supposed to fix it. I am not confident this will work. Looks to me like StarShip V1 is a failure that can’t be fixed, and Elon does again what he does when he can’t deliver: He announces something new. Bigger. Better. Faster. Cheaper. I find Musk less credible than a used car salesman. Much less.

What if heat shield contains materials such as charcoal or coke? Or some layer of silicon dioxide(quartz), beneath heat shield?

[@ColbyAzimuth]

Yes

There are many interesting stocks in many industries that you might follow. You don't have to act on every forecast, so I'll suggest that you work with a financial advisor who can help you choose the best times to purchase and sell the shares or ETFs you want to acquire

[@allphic8445]

You should know it's easy and hard to make that much profit. I say EASY because it's very possible to make that much, and Hard because you'll need professional assistance to do it, I'd suggest you get assisted by a market advisor.

I'm an advocate for having a diverse investment strategy. I grew to a 5 figure mark with my portfolio having exposure to different areas of the market, including small and large-caps of the ETF index, blue chip stocks, coins, grade bonds and alternatives like cryptocurrency markets, as this helps manage the overall risk on my portfolio managed by my FA.. Credits to my adviser, Jonathan, i have no doubt investing more

[@jackmarsh2730]

Please can you leave the info of your investment advisor here? I'm in dire need for one!!

[@worldofrandometry6912]

If the plan is to refuel it on its way to Mars, can it not be refueled in Earth orbit to make a controlled landing to Earth under its own power with no need for a heat shield? Or would too much fuel be required for that event?

Wow, Musk reinvents technology from the 1960s. So much for quick turnarounds.

Good Morning! Do you know what they have come with for a Heat Shield composite yet? Or is that still a secret? It has to be a revolutionary design. I anxious to hear what you have found out. I know when you find out you will let us know. The heat shield is probably the most critical part of space flight at this time. I believe the power and thrust journey is just the beginning of the power he plans for Starship. He is like the Eveready Bunny. He keeps Going and Going and Going. You are absolutely right when you say any company in any industry could learn from. You couldn't say it better. I hope the American industrial base is listening to You my Friend. My Son and I are listening to expand our business. You always do a Great Job. Great Episode. You covered a lot is a short amount of time. Have a Great Sunday.

[@alphatech4966]

We do not have any additional information for the material added below the heat shield. But we will try to update the latest information soon!

Thank you so much!

When will Star Ship get it's Necular Reactor?

[@lesliecompton4061]

heat tiles should be plastered all over the launch site and shaped to do a job that lasts moments -- fast replacement is the key -- its knowledge they already have

[@k.sullivan6303]

What about installing Teenage Mutant Ninja Turtle shells all over that sucker?

[@MichaelBrown-np1kc]

Simple Solution is use Heat resistant Paint on top of Heat Tiles which will seal the Cracks so hot Gas can't get into. Heat Resistant Paint is the better Solution!!!!

Thanks, do you have a part number 😊

Ah blaa tev :)

[@flyjim99]

Ablative, oblative, or abrasive? It would seem that if you know the correct definition and the difference, you shouldn’t need to worry as much about the way it it stated in the video. And if you think the person that doesn’t know the difference gives a hoot, you might be wasting your time.

Do UFOs use heat shields ?

[@dasmike1]

We should seriously consider removing the “I” and just calling it “A” …😅

[@ecoidea100]

It's getting heavier and less reusable, but ok, the idea is that it has to be reusable only once to return from mars.

[@avgjoe5969]

Its also getting more throw weight. Compare V2 to V3. Raptor V2 has 230t thrust, V3 is at 269 and targeting 280t thrust. So the payload is going up. Not down.

[@Auqalungangler]

They need a flexible spray on heat resistant coating so it's a one peace sheet that's held on by it's contact to the entire service there sorted my account no is and many thanks elon

[@Denvermorgan2000]

It’s not fixed until they implement it and prove it works and its ablative not abrasive I’m blocking this channel.

[@brendanwood1540]

Ablative not abrasive. You got it right eventually! ;)

Elon won't stop development he might slag of once they got everything reliable!!!
