Elon Musk SpaceX Genius Solution for Flight 4!
Amid the excitement surrounding the Starship Flight 4 launch schedule over the past few days, another issue has garnered significant attention: The cause of the explosion of both the Super Heavy and Starship during the third Starship launch has just been updated in the latest SpaceX announcement.
So, what went wrong with the vehicle in the third Starship launch? How did SpaceX solve this problem? And Why does SpaceX use those solutions?
Let’s find out in today’s episode of Alpha Tech:
Elon Musk SpaceX Genius Solution for Flight 4!
On May 24th, alongside announcing the official launch date for the fourth Starship flight, SpaceX released a detailed update on the third flight.
The update seems very timely to answer all the mysteries we've been wondering about for the past two months.
Elon Musk SpaceX Genius Solution for Flight 4!
During the third flight of Starship, when the second stage of the rocket reached space, the vehicle was subsequently lost during its return journey.
The vehicle began to lose attitude control during its movement in space. This loss of attitude control resulted in a non-nominal reentry into Earth's atmosphere. SpaceX was able to maintain communication with the vehicle up to an altitude of 65 km before telemetry was lost due to excessive heat.
The most likely root cause of the unplanned roll was determined to be the clogging of the valves responsible for roll control. In response, SpaceX has added additional roll control thrusters on upcoming Starships to improve attitude control redundancy and upgraded the hardware for better resilience to blockage.

Reminds me of Iron Man, "how did you solve the icing problem" LOL

[superidolxaurong]

It got move to June 6, still impressive space x!

The size of the launch zone is incredibly small. Relative to starship 3. Can almost be hoisted directly from ground position into it's vertical launch position.

Good Morning. Great explanation on the explanation of the fuel system, the engineering, its functionality. I was looking for more detail of the internal fuel system. Good Job. Great Update. Have a Great Sunday.

I AM SO EXCITED ABOUT STARSHIP ! IN 17 MONTHS WE'LL BE LANDING PEOPLE ON THE MOON !

[unclefart]

Looks like a wild week coming up. More history to be made. (And not from Boeing.)

[David-vkq]

Optimus will be the first pioneer to Mars 🧐

[JohnDoe-txlq]

instead of the extra Ring they've added for separation, would be cool if they could have the Grid Fins (modified & stronger) positioned at the very top of the Booster. They would be set totally upright on take off, sticking up beyond the top and taking the full weight of Starship.
After flight Separation (with the Grids letting the engine's energy out the sides instead of having the new Ring), the Grids would rotate 90' down and guide the Booster back down, as they do currently.
I realise this isn't a small change, would need serious re-design, but the Grids would do two jobs and save some serious weight. Just a thought. 🙂

I can see why the US military want control of Starship.
It is a dream the military had for decades, travel to any place on the planet in 30 mins, with 100 yons of cargo.

[ruthlemler]

There are a lot of hateful people on this site. I wonder what they’ve done lately. I suspect not much.

[k.sullivan]

WOW! It seems Space X is making quite a few changes in each of these test flights. I hope that so many changes do not cause confusion in future analyses of what went wrong. There will likely be things going wrong, but hopefully they can figure out the problems.

[TexanBurgler]

They should plan for a space booster stage fitting in between 2 starships that turns around after starship has escape velocity and goes to the propellant depot for next flight. It would reduce the propellant needed to carry to destination and increase payload.

[garylester]

I suspect part of the problem is the methane is boiling off due to the pressure reduction from being used rapidly, and having a refridgerant effect in the tank, which is super cooling the oxygen tank, also having its own refridgerant effect.

Elon is making Icecream via rocket motor....

Easy to fix, temp controlled heat exchangers from engine waste heat to keep tank temps and lines temps above freezing. Maybe best done as concentrics in lines. ie over size the lines, run a central tube thru the center thats you controlled heat pipe. raise the temp above freezing danger, but not to boiling point.

Filters are called "future plugs" in practical engineering....

[BrettCorkum]

Looks like the shuttle banged a silo and keeps going challenger.

[alanhart]

Starship entered the atmosphere in wrong orientation.

[jeffreybrown]

To Elon Musk: Launch Optimus on Starship, See if Optimus canbe controled from ground.

[RonColeArt]

What if the HSR remains attached to Starship instead of the booster?😮

[Daveyk]

I think the problem with the "catching" of both the 1st and 2nd stage is the un-reliability of the raptor engine. They seem to blow up when you turn them off. If they survive turning them off, they don't relight reliably.

[JimmyRussell-zdqo]

Space X should open tour guide to bring in money.

"Frequent and consistent launches are are crucial for spacex's development process" Yeah, but if you aren't ready, what's the point? Frequent launches and repeated failures might be consistent, but does it get you anywhere?

It sounds like they made changes in flight 3 to correct issues that apparently didn't solve the problems. And if they are still investigating, why go before the investigation is complete?? Sounds like they are quite unsure of this next iteration of changes. This doesn't make a lot of sense unless you are just looking for check marks on a calendar. Maybe it's time to step back and re-evaluate the process.
