I would assume a place like pluto is prone to sublimation, so hard to know if its truly comparable. The abundance of unexplainable bio-carbons we keep finding in space tells us there's something going on chemically we just don't understand yet.
The issue is what is bio carbon. For small molecules, It's very hard to define what is part of "organic" chemistry and what is not.

Well, all the pork that stays on the Big Bloated Bill has to come from somewhere.

It looks like slow motion footage but the camera is wobbling too fast for it to be.

It's almost the opposite of how movies fake large explosions by overcranking the frame rate on miniatures. That fireball was at least 800 feet high.

The wobble was probably the cameraman running, lol.

I had my cousin from SpaceX over for dinner on Monday. He said the next two Starships (after this one) will have the "fix" for some of these explosions, which is to increase tension on bolts that have been sealing pieces of a fuel vapor manifold together, which have failed due to thermal expansion and contraction cycles during use. Fuel-air mix gets into places where it's not supposed to be and... boom. In the future these parts will be welded. Those versions of Raptor should launch towards the end of the year, or early next year.

There are already 3-4 more Starships constructed waiting for launch, with more in the pipeline. Fixes are applied dynamically to existing models, as possible, as new data comes in from these failures.

Damn, check them out on their site... really nice, responsive zoomable images that the above are only just pieces of.


Just like looking up from a genuinely dark location in the middle of the night, it's really hard to comprehend exactly how much you are seeing here:

I feel ya man. In the past month I've been diagnosed w/ arthritis in my neck, mild carpel tunnel in both wrists, obstructive sleep apnea and the glasses it was determined i needed for the first time in my life in November feel woefully inadequate, like my eyes have gotten used to them and gotten worse since.

Have you been tested for the betes? This could be high blood sugar. It makes your vision worse when it's high.

Yeah, im controlled type 2 w/ Oz. No serious eye neuropathy in November but glad I have it as a benchmark to compare to when I go back.
