ah, ok. that makes sense.

the launching part I don't have any qualms with, less gravity, less atmosphere. but producing that much seems like a huge leap. especially just the logistical problem of launching that many, plus the overcrowding we are already seeing.

I dont think there is overcrowding, only a debris issue. Musk said 11K satellites is like 11K people on Earth..odds of bumping into another human is remote, plus it is a much larger circumference than the Earth and has depth from hundreds of miles to geosynchronous orbit, like 22k miles.

its already an issue we are running into. its only going to get worse

and humans aren't moving around at mach whatever speeds. and if you have geo stationary satellites you are going to have other orbits that cross its path.

How many satellites could fit in Earth orbit? And how many do we really need?

The number of satellites orbiting Earth is rising fast, thanks to private companies such as SpaceX. But just how big will these "megaconstellations" become? And what problems might they cause?

the max saturation is believed to be 100K in LEO and we are at 11K total including GSO..low orbit sats burn up in atmosphere after lifespan.Junk is the issue right now.

the more satellites we have the more junk we will have.

I have seen reports of successfully being able to send "power" up to space via lasers or something sci-fi-y. I didn't know if that is what Elon meant here, or if he is going to ship it up to the moon as a fuel source for that amount?

or do they mean mining the moon for that much?

You can generate power from orbital satellites by either a tether to another satellite (d berates electricity as it passes through the earths magnetosphere) or via solar arrays.
The problem then is how to get the power down to the ground.

It looks like Blue Origin is finally gonna launch something.

Did NASA just hold a press conference on releasing pictures of 3I/ATLAS and only show three pictures taken up to early October? Seriously?

I'm pretty sure NASA shutdown outside ISS flight operations during the shutdown so that maybe all they have.

That might be true, but IMO It was bad look on NASA to hold a press conference like that and the panel was from NASA’s HR department and couldn’t answer some of the questions which are knowns.
