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.

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

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.

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.

@@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.

@@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.

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.

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.

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.

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?

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
