  • -The incident highlights significant operational failures, as engine shutdowns should not cause communication loss, indicating a lack of redundancy in systems.

    • SpaceX’s pre-flight checks failed to identify potential leaks, suggesting inadequate safety measures or poor execution of checks.

    These points are really silly. Two engines exploded causing the ship to tumble. I’m not sure what they think additional communications redundancy would help with at that point.

    And how do you indefiy a fuel leak on the ground that hasn’t happened yet? It was caused by vibrations at a resonant frequency that is only reached at a certain fuel level?

    • Starship’s design has been criticized for overestimating engine thrust capabilities, limiting its payload capacity to 40-50 tons, which is less than the Saturn V.

    Who said that? That’s really silly. And isn’t that payload with full reusability?

    Space is hard, it’s literally rocket science. The embarrassing thing is it failed in the same way twice. But finding these resonance issues that only pop up in specific fuel states, makes sense it’s hard to pin down. I think they’ll need to characterize their vib spectrum as fuel burns down, then analyze the harmonics of the hardware and make sure they don’t couple. It isn’t easy, but they should be able to.

    Edit: thanks for the summary, I just disagree with the article.








  • Thanks! Sounds like limiting risk from the California bill is a plausible reason, but it isn’t confirmed.

    Legal Definitions of “Selling Data” Under the CCPA Are Broad: As noted above, the CCPA’s definition encompasses many data-sharing practices that may not align with common understanding of “selling data”.[16] Even if Mozilla was not directly selling user data, its search partnerships, telemetry data sharing, & sponsored content could have been interpreted as data sales if Mozilla received any financial benefit from them, all of which were actions that Mozilla has already been transparent & upfront about.

    Mozilla’s Search Engine Deals Could Be Considered Data Sales: As mentioned earlier, these partnerships could legally qualify as data sales under the CCPA definition, despite being an existing part of Mozilla’s business model that consumers are already aware of.[1]

    Sponsored Content in Firefox’s New Tab Page Involves Data Exchange: Mozilla dReferencesisplays sponsored content and ads on the Firefox New Tab page, which may involve user interaction data being shared with advertisers.[11] Even if the data is anonymized, the CCPA considers certain types of aggregated data as personal information if it can be linked back to users.[16]
