Lots of different estimates, but looks like between 11% and 20% of ghg emissions are livestock. That’s way higher than I thought.
Yeah, given campaign costs in the US at least, that is really tiny money.
They’re still doing Polaris missions though right?
Are you saying SpaceX is selling launches at a loss? I don’t think musk is paying for SpaceX launches with Tesla money.
Yeah but that doesn’t mean SpaceX isn’t a fantastic rocket company. Why is over promising an issue? It’s still fantastically cheap and capable. You aren’t buying rocket launches, and the people who are are looking at the current performance, not future projections.
Seems like you’re comparing SpaceX to Elons promises, not against the rest of the space industry. They’re still much better than all the rest, even if they don’t quite meet Elons promises.
I love the different styles of Cash’s version, nine inch nails, and the Eric Whitacre choral version. They all bring out different parts of the text, and the comparison is fascinating.
4.8kg per day gives 1.75 tons per year, giving an 800% increase. That’s still really big, thanks for tracking down the numbers.
48 tons per day, so it’d need to be less than 0.08% aluminum to double it.
Yeah you’d need to put up fewer sats per launch. But they might still have enough lift capacity on starship to do that.
Wood is interesting, but the article doesn’t address off gassing at all, which is a huge problem for communication satellites. Is there a way to keep the wood from off gassing? For 3d prints in vacuum, they metal coat them to keep the gas inside. Or maybe you could resin soak them? With hopefully an extremely UV stable resin. But I didn’t know what the weight trade looks like then, resin is heavy.
But if you’re looking composites anyway, carbon fiber would be another great option. Lightweight but with a few manufacturing constraints. But should burn up to carbon dioxide on reentry.

About 48 tons of meteorites enter the atmosphere every day. I couldn’t find the elemental distribution, but I’d guess there is some aluminum in there. How much of an increase is 14 tons aluminum per year over the many tons of aluminum entering the atmosphere already? That might be good to get a rough estimate of how impactful this is.
SpaceX has been receptive to design changes to starlink in the past to minimize impact, like decreasing reflectivity and reflection angles for astronomers. They might be receptive to moving to different alloy for the body construction.
Magnesium comes to mind that would be light but expensive. Steel alloys might be cheap and heavy options for later when starship is operational. Would those have similar effects on ozone, or is it only the aluminum oxides?
Have any countries named their EEZs?
At least on their home turf with their western equipment, yes. Russia is throwing pretty much everything at Ukraine, and Ukraine is doing pretty well.
Plus they’re asking for more money that they haven’t stolen yet. Russia doesn’t even control large parts of the territory it’s decided to annex.
There are 16 thrusters on the service module and they only need like 4. One is malfunctioning. They’re trying to diagnose the problem to fix it for next time since the service module burns up on reentry.
