hydrofluoric acid

Not sure if serious but just in case: why would there be any HF in a lithium ion battery?

Are the parts both made of PLA? Silicone caulking would be elastic and easy to break but it might also become unstuck on its own since the adhesion to plastics is not great.

Rubber cement would also work in principle but it might not be reversible at all and depending on the solvent and what plastics you used it might damage the plastic parts while the solvent is drying. Acetone can damage ABS plastics for instance.

Would a low-temp hot melt gun work? They can operate as low as 120°C which might be low enough to not destroy the plastic parts.

i think for Ariane 6 the marginal cost of a launch is simply still too high to ever get to those numbers. Maybe Ariane 7 will be better in that regard, assuming they manage to make the boosters reusable.

Arme Menschen sind eher kriminell

leider eine oft von großen medien verbreitete Fehleinschätzung. Es gibt sicher Zusammenhänge zwischen Armut und Kriminalität aber diese sind eben nicht 1 zu 1 wie du es beschreibst. Es gibt ganz sicher einen kausalen Zusammenhang zwischen der Art der Kriminalität und der sozialen Schicht … zB wird ein Millionär statistisch betrachtet vermutlich weniger Raubüberfälle durchführen um seine Drogenabhängigkeit zu finanzieren als ein mittelloser Obdachloser, dafür aber vermutlich mehr Steuerhinterziehung.

maybe time for CV dazzle: https://arxiv.org/pdf/2412.13507
This is not foolproof (read the paper for details) but it can help to protect peoples identities if used correctly.

It makes a lot more sense once you consider where you are starting from: a rock hurtling around the sun at breakneck speed (29.8 km/s). You can not really bullseye something when you are going almost 30 km per second sideways to it.

If i read your question correctly then you are wondering if the voltages you see are going to work for TTL devices. As you can see in the linked tutorial it is not just about nominal Vcc levels. Every chip is different. :)

Eutelsat

OneWeb is owned by Eutelsat and i think that is the one they refer to in the article. OneWeb satelites use 450 km - 1200 km orbits so 3 to 8 ms delay assuming the signal goes straight up and straight down again.

those missiles are almost certainly intended for ground launch.

legitimacy can be seen as a scale. In the last 19 years the US has never been the most legitimate democracy but i dont think it could have been considered "undemocratic" or autocratic since the end of the civil rights movement either.
