SpaceX (general discussion)

I am sure that if SpaceX are going to launch tomorrow they will only launch if they are certain that things are going to be okay with the rocket, after all they do not want to have the second Starship to go wrong.
 
For the record. Success after launch means the rocket doesn't blow up. OK?

"Uh, Mr. Musk. Those hot exhaust gases tore up the launch pad."

Seriously?

They knew that in Germany during the war !!!

For the record, I disagree. Success would include the possibility of an explosion.

I don't believe the Germans had Fondag.
 
I think the biggest problem is the tight window limits mitigation. If there's any error or red flag last minute, there's no time for a fix. No one launches a stack worth hundreds of millions unless everything is reading green.
 
Then the Saturn V blowing up shortly after launch in 1969 would have made it sort of successful?

They did test all components prior to all this, right? Static engine tests at full load?
 
Y'know I've never been this excited about anything space-related before. (It might be out of topic but I just needed to express it somewhere.) But unfortunately I won't be able to watch it.

Is it a new attempt at the previously failed mission, i.e, reach the orbit and then splash down in the ocean near Hawaii?

What a Launch !
all Raptors worked perfect
but both stages had RUD
According SpaceX second stage had unexpected activation of Flight Termination system after Engine shutdown
what happen with Superheavy unclear (same issue ?)
 
New World record, biggest heaviest rocket launch
most number of running rocket engine: 33

Only issue: why happen RUD and its fault of FTS ?

At least the Launch site is still standing
 
Now, is the FTS reliant on cables?

The SuperHeavy pitch might have yanked them with a bend...it could be that it could have made a controlled descent without it.

Maybe the hot staging did a burn through?

I want to see more footage.

One more argument for parallel staging?

On wire harnesses, not mechanical
no
Maybe
not at all
 
The fact they had all 33 engines firing and successfully got it's payload to where it needed to be is an incredible feat in itself. Probably the most technically challenging because it is difficult to model what is going on while 30 engines are running. Shame they couldn't get Starship to the planned profile, but encouraging none-the-less.

Looks like FTS on second stage acted because of telemetry loss.

The Flight Termination System works on Parameters
if rocket deviate from trajectory or certain parameters are fulfil.
Next to that can safety range officer give the FTS remote order to detonate.

Seems that B9 had serious issue with raptor engines during boost back
it spit out parts from engine bay before FTS went active...

I had wondered what had happened to the booster Michel Van, things seemed to be going well up until that point.

The re-light after staging immediately had issues, the number of lit engines kept falling off asymmetrically. Wonder if an engine went RUD energetically at re-light and that caused all kinds of issues.

The point is this is Tech on it limits
This not falcon 9, but a 150 ton 33 engines Superheavy, who has to make 180° turn.
Remaining propellant splashing around in large Tanks.
Engines just shutdown and with still spinning Turbo pumps has to reignite again.
This time under high G-load during 180° turn.
Next to that they suck in mixture of gas and liquid, what damage the Turbo pump, until they RUD.

i look into this for fictional Moon colonisation
Here the booster make not return to launch site but stick on ballistic trajectory after engine shut down.
deploy parachute land in ocean and tug back to launch site for reuse
keep it simple and easy.

that doesn't work for the nasa funded exploration missions - spacex needs to refill starship ~10x to get enough fuel onboard for human-scale interplanetary work, and at the timing/pace for that, you need to a full a return to sender
 
FAA launch mishap investigation.

As expected, the SpaceX Starship mishap triggers a SpaceX/ FAA investigation. No injuries or property damage reported.

STATEMENT
This information is preliminary and subject to change:

A mishap occurred during the SpaceX Starship
OFT-2 launch from Boca Chica, Texas, on Saturday, Nov. 18. The anomaly resulted in a loss of the vehicle. No injuries or public property damage have been reported.

BACKGROUND

A mishap investigation is designed to further enhance public safety, determine the root cause of the event, and identify corrective actions to avoid it from happening again.

The FAA will be involved in every step of the mishap investigation process and must approve the final mishap report, including the corrective actions.

A return to flight of the Starship Super Heavy vehicle is based on the FAA determining that any system, process, or procedure related to the mishap does not affect public safety.
