More than 7,000 Starlinks in orbit now, and they have permission for 42,000. Even conservatively, at peak operation, they'll dump 25x more aluminum into the stratosphere than falls naturally as they launch and burn up 20-25 sats PER DAY. What will that do? We actually don't know. That metal is already measurable. SpaceX is just running this experiment.

We need fewer satellites in orbit with longer operational lifetimes. THAT is the new engineering challenge in LEO.

@spacegeck @AkaSci But I’m not sure how drizzle is implemented within that flow, so it might or might not apply in this case.

@spacegeck @AkaSci as far as I know, lucky imaging is actually a simplified name for a multi-stage process: 1. A subset of best-quality images (there might not actually be any really pristine ones, depending on the conditions), and 2. Stacking algorithms which reject individual pixels from individual selected images based on statistical measurements. This might catch walking people etc.

@spacegeck @AkaSci is it really that much more dynamic when compared to planetary images which are affected by seeing? I’m not an expert in the internals of drizzle algorithms, but they must be able to cope with quite some variance?

@AkaSci @spacegeck Yes. Astrophotographers regularly do sth similar called “drizzling”, especially for planetary photography which is usually done by taking raw video to get 1000s of shots, the best of which are selected and combined (“stacked”). Drizzling is one technique in there to increase effective resolution.

Deutschland hat die erneuerbaren Energien finanziell extrem gefördert, was zu einem so günstigen Preis von Wind- und Solarkraft geführt hat, dass sie weltweit genutzt würden. Sozusagen die größte Klimaschutzmaßnahme überhaupt weltweit.

Klimakrise spitzt sich zu - Welche Rolle spielt Deutschland?

Die Erdtemperatur steigt auf einen Höchstwert und die USA als größte Wirtschaftsmacht der Welt wählt einen Mann zum Präsidenten, der Ölbohrungen ausbauen will. Was tun?

This thing where LIDAR data is revealing ancient cities covered with jungle? I love it so much.

It has always struck me as awfully coincidental that the conventional history of "civilization" focuses on areas that are relatively easy to survey and that preserve things well.

I look forward to what else we find. (And maybe someday we can do the same for the American continental shelf.)

Eine Frage an Medien und Politik: Wenn wir 0,02 % der Menschen in Deutschland, weil sie Straftaten begangen haben, nach Afghanistan abschieben und 0,02 % der Bevölkerung, die sich weigern, arbeiten zu gehen, obwohl sie könnten, härter bestrafen, dann wird das auf die restlichen 99,96 % genau welche Auswirkung haben? Ich verstehe nicht, warum wir die ganze Zeit diese Scheindebatten führen. Warum bestimmen die rechten Populisten den Diskurs, statt dass wir über echte Probleme sprechen?

CEO of Perplexity, the AI search engine company caught scraping web content even after its creator opted-out, says opt-out framework (robots.txt) isn't "legally binding"

It's like when you say something shitty, have no excuse & fall back on saying "it's freedom of speech"

Can confirm from personal experience, programming with AI is exactly like this.
