Looks like second stage broke up over Caribbean, videos of the debris (as seen from ground): https://x.com/deankolson87/status/1880026759133032662?t=HdHF... https://x.com/realcamtem/status/1880026604472266800 https://x.com/adavenport354/status/1880026262254809115 Moment of the breakup: https://www.instagram.com/reel/DE52_hVSeQz/

I have a boat and want to pick up floating heat tiles in the ocean, do you think we can find the parts by Puerto Rico?

No

I absolutely cannot relate to the HN excitement over rockets. What is the point? What are we going to do with them? It feels like half religion half misplaced techno-positivism. (Also a person who actively platforms outspoken neo-nazis runs the company that is launching them)

Many of the techie people on HN undoubtedly dreamed of building and flying rockets at some point in their tweens / teens till the harsh realities of the material world took over. So they are vicariously living childhood dreams... Just like many "normal" people live theirs by following sports teams or celebrities. To each their own :-)

Will be interesting to hear the postmortem on the second stage. The booster part seemed to work pretty flawlessly with the exception of a non-firing engine on boost back which then did fire during the landing burn. If the person doing their on-screen graphics is reading this, I wonder if you have considered showing tank LOX/CH4 remaining as a log graph. I believe it decreases logrithmically when being used (well it w…

I don't believe they throttle the engines up or down much during the second stage burn. Fuel decreases ~linearly and thrust is relatively constant. Acceleration increases as fuel mass decreases.

I would be surprised if that was the case, my reasoning to that is that computing where a thing is going, when it's under going with changing acceleration AND changing mass, is pretty complicated. Especially if you already have the capability to throttle the engines and keep 'a' constant.

They might, I'm not saying your wrong, I'm just saying that I cannot imagine how you would justify the added complexity of doing it that way.

Looks like something out of a sci-fi movie.

The number of SpaceX video clips that I know are "actual things really happening" which still activate the involuntary "Sci-Fi / CGI effect" neurons in my brain is remarkable.

Yeah. I know that feeling.

That tower catch. That _had_ to be a new version of Kerbal, right? The physics looked good, but there's no way that was real...

I take it if SpaceX debris hit and destroyed a boat the owner can claim damages from SpaceX? Does international space law allow for this?

https://en.wikipedia.org/wiki/Space_Liability_Convention Only used once, when the Soviets dropped a nuclear reactor on Canada. > States (countries) bear international responsibility for all space objects that are launched within their territory. This means that regardless of who launches the space object, if it was launched from State A's territory, or from State A's facility, or if State A caused the launch to happe…

Every one of these are like right out of a sci-fi novel. It makes me truly excited for our future in a way little else out there does. Between this, AI (even in its current LLM form), and mounting evidence suggesting the entire solar system is teeming with at least microbial life, we are going to become an interplanetary species far sooner than many “skeptics” imagine. We are just one more lander / sample mission / w…

View of previous catch (flight 5) from a very distant vantage point was even more incredible for me. You can see the scale of things right there

Anyone has similar view of this landing?

It’s crazy how fast that ship is moving and how big the explosion was that it looks like something much, much lower in the air went boom. It was transitting the sky faster than a commercial aircraft does. So it gives an impression more like a private aircraft breaking up at 5-10k feet.

That doesn't negate FTS.

Imo if SpaceX thought it was possibly FTS they wouldn't say RUD. They still had telemetry for multiple seconds as it pitched wildly and engines failed, if FTS didn't trigger then it probably didn't at all.

Yeah I thought about that some more and at that altitude and speed the FTS is usually already deactivated.
