Releasing all kinds of cool chemicals into the upper atmosphere, and no one really knows what kind of effect that will have. Cool.
The number of satellites Starlink plans to launch will quintuple the number of spacecraft in LEO.
It absolutely is clogging up LEO, and multiple space agencies share that opinion. NASA wrote a whole letter on the potential hazards Starlink presents, and the challenges it adds to critical missions.
The speeds these satellites are moving at make this comparison so bad it's embarrassing. Starlink satellites have accounted for over half of all close calls since they've been in orbit, and when the constellation is done, it's estimated that that number will grow to 90% of all close encounters.
Lol what the fuck are you talking about, do you know how much shit burns up in our atmosphere yearly? It's a nothing burger.
Ooo nooo, you do realize how large space is right? It's also, not on a flat plane like the earth is ..
Yes and spacex addressed those concerns. It's not clogging up anything. Space is massive...and unlike the earth it's on a 3d plain.
Go look up what a close encounter is...earth has close encounters with big rocks all the damn time, and it misses shit by hundreds of thousands of miles... again space is huge.
About 60 tons or so of rock a day, which mostly deposit oxygen, magnesium, and silicon into the atmosphere, with known effects. Once Starlink is fully up, an additional 2 tons of aluminum satellite per day will be burning up in the upper atmosphere, giving off alumina dust and potentially wreaking havoc on the ozone layer and blocking sunlight. It's impossible to know the full effects of that drastic of a change.
The satellites are in low Earth orbit (LEO) though, a very specific, very small, and very crowded region of space.
You know what you're right, they did say they'll steer Starlink away from the ISS during docking, how nice of them. Still doesn't address the rest of their concerns in that letter, nor the concerns of the rest of the scientific community.
This is a weird thing to repeat twice. It almost sounds like you think the earth is flat.
Any encounter between two craft that get closer than 1km.
Again, the "big rocks" that burn up in the Earth's atmosphere have known effects. Also I don't think you know what a close encounter is - the whole world would know if a "big rock" came within 1km of the Earth's surface.
Ah, yeah, you have no idea what a close encounter is.
Again, we're talking about low Earth orbit, a very specific, very small, very crowded region of space. Where the spacecraft there are traveling at speeds up to 30,000 kph. Dismissing all that and just saying "but but space is huge" is ignorant.
Anything that needs to dock with the ISS will fly through Starlink's orbit to get there. Also docking adjustment maneuvers are usually performed right at Starlink's orbital altitude. It does conflict, or else NASA wouldn't have included it in their letter.
