LazerFX, 4 miesiące temu do astronomy w Brightness of first Chinese broadband constellation satellites alarms astronomers

And that’s because SpaceX at least try to minimise pollution (both light and radio). Not successfully, but it’s minimised.

The Chinese don’t give a fuck, just like they don’t give a fuck who their toxic rockets land on when launched over their own people.

This is a pop-science problem and not a real science problem. Any astronomy imaging system worth its salt has image stacking algos that remove transients easily enough.

Here’s an actual scientist saying the number of satellites interferes with astronomy.

troyunrau, 6 miesięcy temu

Hi, it’s me. An actual scientist. Did grad school in planetary science. The same techniques we use to spot asteroids are the techniques used to spot satellites. But removing them is even simpler. It’s not algorithmically hard at all.

In fact, it’s so simple that I’ll write it out: take several images (at least three) in quick succession and take the median value across those images.

Oh hey, that was easy. Makes a good despeckle filter too for cosmic ray strikes or whatever else.

It seems to be all talk and no rock. Do some manned flights, ESA, and we’ll see.

Why? Ariane 6 seems more like a Strategic need being filled than a useful launch platform.

Strategic need in terms of economics?

Gork, 11 miesięcy temu do astronomy w U.N. committee to take up issue of satellite interference with astronomy

COPUOS operates by consensus, requiring approval of all of its more than 100 member states to move forward on any issue, and thus allowing even a single nation to block action

That’s a shitty way to get anything done. Unanimous approval should only be for really big issues. Otherwise just let it be a majority vote.

Countries were felled because of veto powers. It’s a stupid approach to most things.
