  • I think this is all coming from the flap hinges. The hotspots on the leeward part are sparks from the sides. They fall that direction since the re-entry is applying some drag.

    The intentionally missing tiles were just on the engine skirt section IIRC. So this isn’t necessarily a problem with the main heat shield. The V2 flap design might mitigate it completely. We can’t really say much from just one (alleged) image.

    Edit: The IFT7 stream stated SN33 has missing tiles spread over the entire heat shield this time.

    Edit2: Not going to see anything from IFT7 re-entry.







  • Actually, with regards to payloads - a bigger issue is how are they are going to deploy customer payloads. Unless they have flat-pack sats in the Starlink form factor, there’s no way to get them in or out of a Starship. I think solving that - without compromising the structures or heat-shielding is a bigger concern. Which is why testing the vehicle with a lower mass, more aggressive launch to find out what is actually needed to survive re-entry, comes before actually loading the thing up.


  • Starship is a test program right now. SpaceX are not in a rush to sign on customers. They are operating the most prolific and heaviest launch system right now. They can handle the avionics and understand the launch trajectory better than anyone. Why waste time making test masses to throw in the ocean? There’s no benefit to doing that with these prototype vehicles. When they are satisfied with recovery testing and go orbital, they’ll launch a load of Starlink sats and no-one is going to care that they launched a banana first.

    For that matter, Blue Origin are launching a tiny space tug on the first launch of their giant rocket. They don’t need to demonstrate the maximum take-off weight of the vehicle. Demonstrating that they understand and can fly the thing all the way to orbit is fine. That will bring customers, which Blue really wants - they don’t want a drawn out development campaign like Starship is having.

    I’m not calling you a hater, I just don’t see how launching a banana could be evidence of some fatal flaw with Starship when it’s only flying sub-orbital test missions right now. Some people seem to think SpaceX is doing all this work just to perpetrate an elaborate scam to fleece American taxpayers. There’s surely much easier scams than doing actual rocket science.






  • Ah yes, the Ares I Crew Launch Vehicle. NASA’s plan was to put the Orion spacecraft on top of a Space Shuttle SRB. The projected development costs were $40 billion in 2009 and it was anticipated to cost about $1 billion per flight beyond that. Despite continued development, to this day, Orion still hasn’t flown a crew. An SRB was what killed the 7 crew aboard the Challenger.

    This was a pretty dumb idea, driven primarily by wanting to keep funding going to the same districts as in the Shuttle era. No one misses that system.

    Thinking that wasn’t capitalism is ridiculous - NASA designed the system and gave aerospace contractors (read - Boeing) a blank cheque to build it. The contractors of course used that money to lobby congress to spend even more money. Did you miss that part?
