SpaceX's Heat Shield Problem FIXED For Next Starship Launch!
Finally happened.
A complete overhaul of the Starship's heat shield is coming.
It's true. Elon Musk SpaceX has just revealed a new generation Starship Heatshield that is twice as powerful.
Find out everything in today's episode of Techmap.
In the previous announcements, Elon emphasized that SpaceX's current focus is on reentry, particularly something that can make it safe. Among that, the heat shield is the biggest remaining problem. It's partly due to its vital level, Elon admitted that even a single missing tile could cause the ship to burn up in the atmosphere.
SpaceX's Heat Shield Problem FIXED For Next Starship Launch!
"Right now, we are not resilient to loss of a single tile in most places, as the secondary containment material will probably not survive."
Besides that, no orbital vehicle, even Nasa's Space Shuttle can make a reusable orbital return heat shield in real meaning.
Flight 4 marked SpaceX's first significant upgrade attempt for the thermal protection system on Starship.
First of all, they intentionally left off two Starbricks to test whether losing one brick was truly a disaster for the mission. Can't help but mention the location of the missing tiles is very important, given that they were located in the ship's engine skirt. If the steel there melted, it would affect the normal operation of engines, likely leading to a failed landing. Yet, the result is so surprising, Ship 29 still had an impressive reentry.
So, what do you think? Is one or two missing tiles truly a big deal? Let me know in the comments.

The third point was replaced by a thinner tile than the others, this is likely to test the heat resilience of something new that I will unveil later.
Or another speculation is the removal of the insulation blanket beneath the weird brick.
That white mat acts as an additional insulation for the hull, besides the heatshield outside. The best part is no part. SpaceX could come up with the idea of ditching that component for weight loss.
The night before the historical Flight 4, Elon also emphasized the dangers of the hinge gap on the flap, allowing hot gas to go through super fast and destroy the heatshield in this area. And, what happened with Ship 29's rear flap was completely within his prediction. Therefore, in flight 5, we will see the hinge gap on the flaps to be sealed.
Of course, work on the flap is not enough to perfect Starship’s TPS, thus, Elon Musk has come up with a new idea.

I expect one day a propulsion system will be developed that is powerful enough with minimal fuel requirements (like fusion) that will obsolete nearly all of this heat shielding. The only reason why heat shielding is necessary is for the extreme friction heat generated by reentering the atmosphere at high speed. A propulsion system capable of slowing the speed of the spacecraft to tens of meters per second could then execute controlled aerodynamic flight through the atmosphere and to the ground without experiencing extreme heat.
Can’t wait to see it. 😍 thanks for sharing
I watched a video on that very subject this morning , it’s on its way soon, or so it seems.

@@jerkyturkey007 🤣
that's just stupid lol you would be constantly fighting gravity and wasting fuel when you can just re enter like normal and use the atmosphere to slow you down there won't be a propulsion system that doesn't involve burning a shit load of fuel it's not possible things like ion and nuclear only work in deep space and provide a tiny amount of propulsion
@@tonysu8860 Wrong! It is mostly not friction, it is compression heating.
Ts = Ta × (1 + 0.2 × mach²)
If there’s anything new here in this video, I missed it. Remove the repetitive info within this vid and with the previous vid, and youd have a 2.2 minute video. Not a 22 minute video.
😊😊😊
The "thin" tile is not a tile...it's the ablative material.
They could have done that on the ground in a lab. A flight test is too expensive.
That's the greatest Starship video I've ever seen!..
Need to get around the net more
Just ditch the flaps and use air duct valves to direct air
Use thrusters.
The missing tiles were placed where the Vacuum Raptors are located. These engines play NO part in the landing, so having a burn through on one of them is the absolute least mission critical area. That's specifically why Space X removed the tiles in that location.
Makes sense. Thanks 😀
When the outer layer gets hot, the heat will transfer to the ablative heat shield, below, I'm guessing. So, if the heat is "averaged out" then the ablative shield will not ablate, I think until the covering shield gets burned or falls out.
The ablation is designed to save the ship if loss of a covering tile occurs, I thik.
If done correctly only certain parts (if any) would be ablated and need replacement, so the reusability of the starship might not be hampered by a few file replacents between flights?
That's my guess.
I Cant Wait For Flight 5!!!!❤🔥
It’s coming!!!!
If .. No Part .. is Good ! ..... Get Rid of the BF Flaps ! ... What good are they ? ... They don't work in Space , are added weight going Up and Complicate coming Down ! ... Use Grid fins instead ..... KISS !
@@robertbrander2074 right, use the powerfull inertial moments that are generated by pairs of single gimbal control moment gyros. I suspect that eventually that system will be used, once the engineers in charge will become familiar with this method. Not to be confused with the attitude control system of double gimballed CMGs used on Skylab and on the ISS.
Make tiles way bigger to limit the amount af gaps
SpaceX had great luck that the Strarship could land somehow properly. If it had been made of aluminum it had failed for sure. The much higher melting temperature was significant that the structure survived although severely damaged.
Space shuttle Columbia would have had more chances to survive if it had been made of steel.
For high-voltage lines, aluminum ropes with a steel core are used for better strength when the ropes get warm.
They have managed to fix Nasa’s errors
The heat shield need to be intercooler👍 with nitrogen to protect the tiles around the surface area that might help to be reusable stop burning up your tile
I remember that Elon mentioned it once. Do u remember what he said?
@@techmap9no what did he say, although it doesn’t sound like it would be a worthwhile investment.
If the missing tiles were by fuel tanks or like in the flaps or any vital area would be catastrophic. Where they left the 2 tiles off weren't so important but if 4 tiles were off that might have changed things in a worse and very catastrophic ending.
Didn’t it previously JUST HAPPENED that you covered this subject three days ago with GENIUS SOLUTION ON STARSHIP HEAT SHIELD ?
Quality information over quantity
Very good job.
❤️❤️❤️
Secondary protection is necessary if people are to be on board even if tiles are sufficient. Seatbelts are secondary protection if all else fails.
Sure, more protection is never redundant
Agreed on secondary heat shielding but seatbelts on a rocket are primary. The vibrations and staging would launch unsecured astronauts.
I’m just being a butt. I get your analogy and it’s spot on!
Simplicity is the answer. Heat blanket. Mix crystal cat litter and 100% caustic soda under heat, sodium silicate outcome. Mix sodium silicate with perlite play around with formula, light, heat resistance and more. Hmmmmmm aye Bro 🎉😅😮
The ablative material probably has phases change capabilities to absorb heat, Lke ice.
👍👍👍
It slowly burns off. The X-15 used a special ablative paint back in the late 50’s-60’s. 65 year old tech, improved to 2024 tech saves the day. We hope.
Don't praise the heat shield before it could fail!
It is like with the soccer championship, teams praised before the match will lose it.
👍👍👍
"A single missing tile" might have been responsible for the last shuttle disaster on re-entry?
@@costrio it was actually a seal between adjacent tiles on one of the wing leading edges.
Did you see how easy it was to remove the tiles? They just popped off. Probably with a nail bar.
Good idea thanks
It was an hour a tile with the shuttle and every tile was a different shape. Efficiency isn’t NASA’s strength. I wonder what MASA’s strength is, propping up failing companies?
Yes, lost of one tilee could cost the mission failure.
No, it depends on where the tile was placed.
Now the ablative material and the thermal blanket would also have to get consumed too. So 3 layers would need to burn away and the steel melt.
We won't know if the new version works better until after the 5th flight.
It always evolves
18,000 heat shields, 18,000 points of failure. Blue Origin Law Firm should sue them for that solution logic.
I think the pins are glue points instead of clip points.
😊😊😊
The way they came off and went on coupled with the “reusable, not refurbishable” design makes me think clip on, but I don’t claim knowledge just common sense. Glue seems so…NASA. Clips seem Space X.
The TV in the opening sequence (for the young folk) ia and example of UHF and VHF (often over the air) television, which required one to have a child become a remote control or the viewers had to decide who would get up to change the channel and who would make the coffee during commercials. (Couldn't evade them so productive folk would do some chore or other while the TV spoke to an empty room. Nationwide broadcasts often resulted in a sudden surge of water usage in some cities as people flushed around the same times. ;-)
Now, my watch has to remind me to stand up every hour?
Couldn’t SpaceX test the new tiles on a Dragon cargo capsule?
Would you want to test dragon tiles and have a catastrophic entry on that vehicle then the FAA has an excuse to ground all Space X Dragons. Look at the Boeing Starliner a very embarrassing misshap. But that's government controlled so putting asternuts in harm's way is okay. But for a Space X without any persons on board a misshap will ground that vehicle for along time during a very long investigation
Why not slow down the speed of the ship BEFORE entering the atmosphere ? No parts
I think the fuel weight is the issue. Having light weight shielding is much more efficient than carrying heavy fuel. Just an intuitive thought, I’m no rocket scientist.
@@Frankthetank-zr5mc I saw a video that explained it would take 40 tons of extra fuel to slow enough for low heat re entry.
I have an idea for a much better heat shield, I’m not an engineer… far from it but the concept may work.
Tell Elon to give me a call!
😝😝😝 hopefully, Elon will read these
@@techmap9 I have a serious concept to propose, if anyone can tell me how to submit an idea to Spacex do tell!
Duct tape, lots and lots of duct tape, duct tape fixs everything.
You could have someone on the inside with a water hose for hot spots.
🥲🥲🥲
Jobs for little people. Love it.
Electrifie
This was weeks ago
“A-Blay-Tive” not “Ab-La-Tive”. Come on AI voice, that’s an easy one and so annoying when pronounced so many times in a short vid. Also no need to keep repeating the same thing numerous times. Most of us get it the first time and appreciate brevity.
Neat content though.
They don’t care about pronunciation or grammar or repetition.
Just put something out every day
This silicone, reminds me of red rtv. 😂
Plesase use a real voice next time...
OHHH...K YOUR REPEATING YOURSELF !!!!!
