SpaceX moved the satellites to lower orbits, so any broken satellites or debris will fall out of the sky within a few years due to atmospheric drag. And they are specifically designed to burn up completely in reentry. The real concern is in higher orbits where debris would persist for millennia. This is not a concern for Starlink.
A collision can eject debris into higher orbits.
I don't think you understand the magnitudes of distance and energy that we're talking about here

Not really. The only way a collision could truly raise an orbit is if a resulting piece of debris had far higher velocity than either incoming satellite which, while maybe not theoretically impossible, seems exceedingly unlikely. Furthermore, the way orbital mechanics works, all orbits resulting from a collision go through the point of the collision, so the collision of two objects in circular orbits can never result in an orbit with higher perigee. The orbit of debris may turn from circular to elliptical with a higher apogee, but those orbits will almost certainly have lower perigees and decay faster.
Well that’s how they got the Challenger disaster. Reused booster ruptured under improper launch criteria revised for management and public relations reasons. Would it have been okay if it weren’t for the wrong go? Maybe, but still the potato quality refurbishment of flown boosters could have done it sooner or later.
Do you have any more details on the booster being refurbished having any impact on Challenger?
If it becomes available i buy or restore an 18 century cannon-ship, over the day i sail and play captain sparrow, and in the night i play StarTreckCrew-VR in my captain quarter's ;-)
We lived for a year in some mountains in Mexico in an off-the-grid cabin. We became accustomed to everything (energy starvation, driving 30 mins to the nearest village, 2 hours to the nearest city, etc) except the lack of connectivity. I bought one of those huge Wifi antenna to connect to an open Wifi of a rural school a couple of kilometers away. It was empty after 2pm so we had 4Mbps just for ourselves all afternoo…
Have you looked into WISPs? https://en.wikipedia.org/wiki/Wireless_Internet_service_prov... You can even setup your own.
This was 7 years ago and I'm pretty sure even today nobody offers WISP in that area.
One of our neighbors who lived a couple of kms from us had a point-to-point Motorola antenna connecting with the closest village. We considered doing that but there was a mountain between us and the village which complicated things. Also connectivity in the area was so bad the only ISP available hadn't been signing new contracts for years. The region was difficult to access and wasn't particularly rich, it didn't make sense for ISPs to invest in upgrading 15 years old ADSL.
Yeah, if it really does deliver ~25ms latency and up to 1GBPS, work from anywhere becomes much more literal. Currently a lot of remote work and things like multiplayer games are limited to areas with reliable broadband. But if you can get that anywhere... it'll be amazing and have a profound effect.
It will work from anywhere after about 90 more launches and thousands of ground relays being installed, and the antenna is the size of a watermelon. So "anywhere" would be limited to vanlife on up, in a place that doesn't have trees, in the markets initially served, which will likely be rural US. But starlink v2? I'll be on a cute Panamanian island :)
