Are you sure about that? I know I've seen conversation about how the Starlink sats will actively de-orbit... though I have to admit I can't find an actual source behind that conversation for the moment.

It doesn't make sense to me why you wouldn't. I imagine with an active de-orbit you could likely have some degree of confidence in hitting an ocean rather than land (current versions don't 100% disintegrate). Plus, even if you are even saving a couple of weeks, if you have the thrusters, why not?

Okay, now that you mention it, I think you're both right that passive deorbit was just a side benefit of the altitude, but not their actual plan. Still, its nice to know that even if they didn't actively deorbit the satellites, they will (relatively) rapidly fall out of the sky once they run out of fuel and/or stop functioning.

Right. I think one of the reasons they are launched below their operational orbit it to help ensure any DOA satellites de-orbit that much faster.

Read an article recently on Europe's launch systems. It talked about what I recall was like a decade of plans, but no mention at all of developing a reusable rocket in the Falcon vein. Blew my mind.

When opinion and reality conflict - guess which one is going to win in the long run.

It does appear they are now actively de-orbiting one of the Starlink satellites:

Regarding ESA, they are actually now dipping their toes in a commercial launch provider program as well:

The Talk-Pollywell forum is very quiet these days.. Even space X completing it's 150 meter hover test of the Raptor engine didn't get a blip..

Thoroughly enjoyed this explanation of the Full flow, closed cycle engine used for the Raptor by Everyday Astronaut

https://everydayastronaut.com/raptor-engine/
40 mins but enjoyable for the layman.

Folks might find this interesting...

The Starship is complete.

And Elon Musk isn't one of the smoothest speakers out there. But THAT, compared to what he's done? Very, very forgivable.

I am still lurking waiting for news, or waiting to post news ;)
