well i was contrasting how say, the hubble telescope is a worthwhile satellite that will eventually burn up in the atmosphere, while starlink is wasteful…
Before you call it wasteful, consider the people who now can use it as a proper link to modern society… Rural Canadians in particular like myself, and others in rural areas around the world.
Canada is famous for its poor quality and expensive telecom services, and before Starlink I paid the same amount for a 1mbps 3g connection, 20gb cap, high ping and marginally usable uptime.
Starlink is bringing modern connectivity to huge areas of the world that were underserved, and breaking local monopolies while it does so. If some satellites have to burn up to do so, compare it to all the e-waste here on the ground created just for entertainment purposes and at least it’s serving a valid purpose.
i have considered that, and it does serve a very good purpose there…
but still, launching a shitload of satellites wastes a lot of fuel and energy, and deorbiting them is rather wasteful.
im sure the same thing could be done without treating satellites like kleenex…
one of those things where profit and preserving the environment clash.
I think we’re still looking at an early prototype of Starlink, and there’s potential to develop it in many ways as our space infrastructure develops. After all, space tech is only now advancing after decades of stagnation, driven by the reusable rocket. It’s hard to think the company that invented the reusable rocket is also all in on disposable satellites, so we have to consider why that is.
The big problem is that things in LEO experience atmospheric drag and need to be boosted occasionally. Starlink sats have ion thrusters to do this and effectively reach EOL when their fuel is depleted.
On-orbit refueling is another core SpaceX goal, and there are also other companies launching experimental sats and tech demos to refuel satellites or otherwise boost them. So someday we will probably have a fleet of shepherd sats fueling and maintaining Starlink.
So why not just bigger fuel tanks then? I think they want these to come back down. Starlink is a massive beta test that turned into a full rollout way faster than expected and a large fraction of the satellites are already obsolete. However as people have already come to depend on the service, they have to keep it working as they progressively improve the satellites. And the easiest way to do this is just to let the old ones burn up and free space in the shells for new ones.
They can’t even launch the real v2 satellite without Starship as the current sat is known as the “v2 mini” and is shrunk to fit in the F9 fairing. I would guess that these Starship launched versions will have bigger fuel tanks and a longer life.
