"1500°C MELT!" SpaceX's New Metal Shield to End Ceramic Tiles Just Break Physics...
The SpaceX Starship program is a thrilling showcase of the "fail fast, learn faster" mantra, where each rocket explosion is not just a setback but a stepping stone toward groundbreaking innovation.
Having mastered the Raptor engine's design through relentless experimentation, SpaceX has now set its sights on revolutionizing heat shield technology.
Gone are the days of conventional ceramic shields; the company is boldly venturing into uncharted territory with cutting-edge metallic heat shields.
But that’s not all—these metallic marvels are designed to incorporate advanced technology to enhance system efficiency, something never before seen in the rocket industry.
This daring leap not only redefines thermal protection but also elevates rocket design to unprecedented heights.
Find out everything in today's episode.
"1500°C MELT!" SpaceX's New Metal Shield to End Ceramic Tiles Just Break Physics...
Flight 6 marks a pivotal moment in SpaceX's journey toward Mars colonization, particularly the reusability of the upper stage.
While some debates persist around Super Heavy’s performance, the progress with Ship was undeniable, which is what we see clearly the most in the thermal protection system.
Following the Flight 5 launch of SpaceX's Starship, significant issues with the aluminum-coated heat shields were revealed. These shields, installed on both sides of the spacecraft, were unable to withstand the extreme temperatures experienced during reentry. The aluminum melted, and the stainless steel hull showed discoloration due to thermal stress, confirming that the aluminum coating was inadequate for the intense heat conditions.

Flight 6 was even harsher when the whole shield in certain areas on Ship 31 was removed, allowing SpaceX to push the boundaries of rocket design. As the vehicle descended, the World held its breath as witnessed something unprecedented, portions of the spacecraft's surface transformed into a mesmerizing bluish hue. This suggests that the temperature in the tile-free zones exceeded 600°C— which is also the melting point of aluminum. This is the result of oxidation rather than just thermal discoloration, given that 304L stainless steel on Starship contains high chromium content, significant nickel, and extremely low carbon content. As the natural self-protective mechanism of the steel, under heat, 304L stainless steel reacts with atmospheric oxygen, forming a chromium-rich oxide layer on its surface.

I just checked, physics is not broken...

I want to know once you get your rocket full of "supplies" to where it needs to go, how do you get it back? At that point you have a BER (a Big Empty Rocket) and no first stage.

IS THERE BEEING THOUGHT ABOUT TO CATCH OR CHANNEL THE ACCES HEAT AND MAYBE EVEN THE ACCOUTICS TO DIRIVE TURBINES THAT CREATE ENERGIE TO REUSE IN THE FACTORIES🙄🤔

A metal of 500kg just fell in Kenya from the sky... The metal was super hot...

[davidbird]

Wouldn't it be easier to simply add side boosters like falcon heavy is to falcon 9, if you need more lift or heavier load???

[jerkyturkey]

If Jeff B and his company Blue Origin would spend less time suing Spacex and instead concentrate on catching up to Spacex, maybe we could take him more seriously. 😊

The Venture Star program had a metal heat shield. It was of nickel-based superalloy Rene 41 known for its high strength, oxidation resistance, and ability to maintain structural integrity at high temperatures (up to approximately 1, 093°C (2, 000°F)). Rene 41 was used in areas that experienced the highest thermal loads, such as leading edges and nose sections. Though extremely expensive, niobium-based alloys (like C-103, which contains niobium, hafnium, and titanium), the melting temperature typically falls in the range of 2, 300–2, 400°C (4, 172–4, 352°F). It seems that the problem is insulating from the high heat transfer of metals.

What is the electrical charge of the high temperature plasma on reentry? Wouldn't it be possible to charge the surface of the Starship to repel the plasma and provide thermal protection? This is done for thermal control in fusion experiments and should be possible for thermal shielding of spacecraft. Should be less mass and complexity compared to liquid cooling. Just a thought.

Tantalcarbid on CFC close to 4000 C !!!!

[jackdelvo]

Not all ships will need heat shields. A fleet of starships could be kept in orbit with only those ships used for earth to orbit supply transport needing shielding.

China says thanks for all the info, they are getting to work copying right now.

I have spent most of my life trying to convince people about future technology and its effects on society. Starship is certainly going to transform Space missions (if it meets its potential) but for the life of me I truly find it difficult to see Starship doing point to point transport even if that ever becomes feasible, of heavy equipment quicker and more efficiently than a C-17 or equivalent certainly in 95% of cases. Seems like pie in the sky to me especially considering the costs involved when defence spending is tight. 6th Gen fighters, hypersonic missiles, railguns, new ballistic, new ships and submarines have all been cancelled or postponed and delayed in recent times due to budgetary considerations yet this frankly bizarre and exotic concept with it seems giant drone loading vehicles for tanks etc would be given finance for the arguable occasions it could ever be practically used. Deeply concerning especially as it would be a juicy target for defenders not to mention the quantum advances the Chinese are boasting (hyped as I am sure it is) they are developing which could breach any code protected, even hardened sophisticated systems. Reminds me of much of the fleet of fancy proposals from the 60s like nuclear propulsive aircraft and in atmosphere nuclear powered rockets.

As I wrote somewhere else, Spacex could protect that metal shield by slowly spinning the rocket on its axis (two revolutions per minute?). It would dissipate part of the heat.

In 1976, July, two space craft encountered the high atmospheric entry temperatures on the way to the surface to Mars, It were the first and second successfull landings on another PLANET in all history of humanity. Viking one landed on the Chryse Planitia , 122.27 North; 312.05 East . Borh landings were soft with a final vertical speed of 8 ft/s.
More than 3/4 of a century

[leightonmacmillan]

Dude, what a completely utterly dishonest and misleading video title. 5 minutes on shielding and another hour and a half of utterly unrelated nonsense. More click-bait trash. I have unsubscribed to this rubbish.

[davidbird]

Elon, why not insulate the tile from the hull, so that a di-electric field can be applied to tile (+ve) with a -ve trail of ions out the rear of the rocket.
That way you repel the atmosphere away from the hull( reducing friction problems), but still leaves you the option to use tiles if the field fails???

[pedrosura]

It doesnt sound like the engineering analysis at Space X is that good. After 6 flights they realized they have a bad design and have to go back to an old option, a trade they left behind. I am not sure if the name is quick iterations or dumb iterations.
This is not typically what happens when optimizing designs. You move on when you are sure you reached a design point. In this case that was a mistake.

Imagine getting to the Moon and after the rocket falls saying, hey that was a bad design, let’s put the old landing legs back.

[ThomasLee]

And this is why so many astronauts died on the space Shuttles!
🥵🥵

[djsandvig]

I dislike Bezos. I hope his rocket is an overwhelming success……IKR?

[Joseph-vuw]

I hate these videos where people fail to mention things in Fahrenheit, ruined my whole chain of thought and it makes the whole thing useless to most Americans unless we stop and take the time to go look things up! It only takes a second to add it in there!!
