Starship Explosion
Is the unplanned and uncharted explosion of the starship section terrible for the space junk problem that apparently exists?

Said no rocket scientist, EVER! BTW, why don't you think the ability to extremely large payloads into orbit - at a reasonable cost - would be "something useful". oh, and a useful payload - a Tesla car, a plastic mannequin, or what? |

Or, to put it differently - a hundred years ago, why would anyone possibly need big airplanes that can fly thousands of miles? That's what steamships and trains are for... |

Hmm, it wasn’t planned to make orbit, but it made space, which it was planned to.
But it would have made orbit even on this flight if the trajectory had been intended to do so before SECO. |
Massive progress, all engines remained operating, staging worked, ship flew some while as intended. Well done!
Impressive view of the shock-cone in the colour pic above. I wonder what damage any resonance of that could do when engine(s) start to fail and disturb its symmetry. But how I wish they'd can the infantile-level "commentary" which is no more than a non-stop hammy commercial for SpaceX - lets's have a bit more of the gravitas, information and Professionalism of a NASA commemtary instead of making it sound like gormless teenagers reviewing a video game. It is seriously trivialising the whole thing. And FFS put an end to the God-awful expression RUD. It is so, so silly, undignified and pointless. (and not the least bit clever, which I sense they think it is) |
So they need to keep more engines burning and not throttle back so far?
So, if we can trust the telemetry from Starship’s flight, there was a significant negative g observed on the booster during staging. More force was transmitted to the booster than anticipated during hot staging, this would have generated a lot of propellent slosh that may have been enough to damage the booster and ultimately cause it to fail. |
I LOVE this view of the Raptors shutting down in segments!!

The initial analysis from Scott Manley:
The BIG problem I see in his report is the massive failure of the heat protection system. The Starship was shedding large sections before staging. That magnitude of damage points to a fundamental problem which will require a completely new approach to attaching the tiles before they try again. In Elon time that will take two months which translates into an Earth time of at least a year. |

Yeah, just like the last " great success!".

Lots of TPS tiles missing on S25 today. It’s important to note that SpaceX likely fully expected this to happen.
On S28 every tile was tested using a suction cup to verify adhesion. This was not performed on S25 and, as a result, a large number of tiles along the ring weld lines fell off during flight. In other words, it’s not as bad as it looks. |

Anyway, what else are you going to call it? You don't really want to use the word "failure" because it takes the narrative the wrong way. The term "explosion" is misleading; a lot of rocket failures aren't caused by explosions at all (Challenger being a good example) and even when there is an explosion it's often caused by the FTS responding to a different failure (eg the first Starship launch). |
I think it is super impressive how fast they make progress and how far they have come. Reusable rockets, cheapo satellites and private space flight.
However I am not sure about the Mars euphoria it must be about money, mining and bringing back heavy stuff to earth not so much about science, discovery and mankind. |
