SpaceX's Starship New Heat Tiles & Welding Just Humiliated NASA Shuttle!
There's a lot of emotion today, but one thing's indisputable: America's not going to stop exploring.
"Thank you Columbia, Challenger, Discovery, Endeavour, and our ship Atlantis. Thank you for protecting us and for bringing this program to such a fitting end."
This is a share of Atlantis/STS-135 commander Chris Ferguson, as they closed out the 30-year career of the Space Shuttle Program on this day 13 years ago.
The end of the program marked Nasa's big failure to the reusable type of vehicle, specifically creating a reliable and rapidly reusable thermal protection system.

Fast forward to now, when Elon Musk tries to build Starship, a fully and rapidly reusable rocket like an aircraft, he also ran into the same trouble with the heat shield.
However, he is always confident that he can solve the problem much better than Nasa.
So, what did Elon Musk learn from Nasa's mistakes to improve his system?
Find out everything in today's Techmap episode.
But before we begin, let's subscribe to the channel to stay up-to-date with the latest space news.

SpaceX's rapid success seems to be something surreal.
Donald Trump highlighted that in his presentation on July 20:
"Three years ago I’m watching TV and I see this rocket come down landing. No wings no nothing; It’s landing on a barge in the middle of the ocean; I’ve never seen that before. If that were government you wouldn’t see that for another 50-100 years.”
Why can SpaceX do that?
To be fair, one of many secrets is to stand on the shoulders of giants. Nasa's mistakes and failures have left the successor with many precious lessons, including “think outside the box”.
Most notable are the lessons from Nasa's Space Shuttle project, particularly the problems with its Thermal protection system (TPS). It's safe to say that not by chance, the agency finally had to cancel the program even though originally, they expected that it could be a game changer. The failure to create reliable and rapidly reusable heat shields was a key driver of Nasa's decision.
Elon Musk also doesn’t deny the technical challenges in producing and perfecting TPS. As he said in an interview with Everyday Astronaut.

How many of us fell for the clickbait title?

[fionajack]

Looks like many have called this video out as click bait. Happens a lot. You should care.

Stainless steel can absorb some of the heat so even without some tiles it can survive entry. The special your of steel allows to be stronger when cold, carries extremely cold liquid fuel that is normally gas at room temperature.

NASA is back to the eighties (relaxing safety) Starliner is proof of that.

Carbon fiber doesn’t tolerate high temperatures and breaks down at high temperatures due to the resin holding it together degrading. It’s good for some things but not for others.

[WyoSavage]

I have faith Elon will find a way as he did with Falcon.

the heat tiles are a remarkable achievement compared to the space shuttle. But building out of stainless-steel verses aluminum has a much bigger effect on the heat tiles as well. For instance, the rate that metals expand when heated and shrinks when cooled has a huge bearing on how well the tile can stay attached. the space shuttle was made out of aluminum which has an expansion and shrink rate of 0.4% to 0.7%. Whereas stainless steel has an expansion and shrink rate of only 0.0004% to 0.0008%. The less expansion due to heating allows for the maintaining of structural integrity. The more expansion and contraction, the quicker the wear. This is why the space shuttle had to have all its heat tiles replaced after every flight.

Please stop with "aestetics". Stainless steel has superior very low and very high temp properties. More damage resistant and also carbon fiber damage can cause delamination and can fail alot easier. Stainless also reflects heat better.
But the kicker is that stainless costs less than $4/lb. Carbon fiber (all costs in) costs $180/lb.

Other than that... nice.

You're being very hard on NASA ... The shuttle was very old technology
.
having said that, ,, it did run for 30 years !!!!

[rwesenberg]

It wasn't the shuttles' heat tiles, but the shuttles were space rated for just so many flights due to accumulated stress and strain. After that, the shuttle has to be refurbishedband re- qualified or replaced.

[anthonykeller]

The problem with NASA is the bureaucratic mindset vs the Edison mindset. Bureaucrats think “incomplete” tests are failures. The Edison mindset thinks 10, 000 lightbulb “failures” results in a list 10, 000 materials that won’t work and one that will. No testing results in no lists of unworkable materials and no lists of things that will work. You just get lots of reports that no one reads, but result in lots of spent budgets.

[GrahamHill-ozbu]

daaah! Polishing steel looks better than carbon fibre. My brain has melted

[tonyduncan]

The clinching argument for stainless steel v. carbon fibre is that the former is RE-USABLE at the destination, whereas the latter is USELESS. (Let us not litter. Amen.).

[jbdragon]

The Space Shuttle killed more astronauts than anything else! 😢

[ungdern]

Everything goes 40X faster once Politics are removed from the equation !

[davidbowerman]

In what way? The shuttle flew its first mission with no faults, and survived 132 flights. Its tiles were not the issue. but where the Shuttle tanks were mounted. Starship literally lost tiles on the first 30 seconds of flight! On every flight. Not just one or two but A LOT. The shuttle was a incredibly complex shape, yet they managed to adhere the tiles better. This wasn't the issue. It's that they are fragile, and can't be hit by debris.
Starship, even with rivets don't stay on.

[robertbrander]

That BF Rocket is just So Wonderful !! Maybe, one day it will Fly and Land properly ... ~yawn~

[KenPaulsenArchitect]

Stainless Steel vs. Carbon Fiber - I doubt that aesthetics has anything to do with the choice. In fact, the starship design is far from "aesthetic" as the inspiration came from Buck Rogers or something else. But rocket design should be governed by function, efficiency, safety, reliability.... not how it looks. The focus on aesthetics is misplaced in this video.

[kensmith]

It is time to take a few classes in manufacturing. The reason carbon fiber isn't used is the mold storage issue. SST doesn't need molds. This report appears to have been written by someone that has never worked in manufacturing.

[PanioloBee]

Will Starship have a means of checking the status of its heat tiles prior to attempting reentry?
