Yeah, from StarCloud 3 onwards, we'll have 88,000, and they'll all fly.
This one is in what they call mid-inclination orbit, so it doesn't go over the poles.
StarCloud, and that's another point here on how janky this one is.
It doesn't even fly in the right orbit, but at least it enables us to test the hardware.
The next one will fly over the poles, and that gives us 24-hour always in the sun.
In the end, they will be deployed in that orbit, but you need thrusters anyway to maintain the orbit because you have drag from the upper atmosphere there.
Yeah, you are correct.
There are many engineering challenges to be solved.
The two biggest ones that are outstanding, and most of our engineering team is split basically 50-50 down these two lines, is number one, as you mentioned, how do you get rid of this heat in a vacuum?
And then number two, how do we make the chips work in a higher radiation environment?
Some of the other problems are being solved by other people.
The interconnect, we've just signed a contract with SpaceX for our next 20 satellites to have a Starlink laser terminal.
That gives us very high bandwidth, low latency connectivity.
Other people are solving some other parts of this.
The core ones we're solving are that.
And so for the first one, for the thermal management side of things,
We are building a very large, low-cost and low-mass deployable radiator.
Now, radiators in space are not new.
It's not a new physics solution.
It's more of a manufacturing and engineering challenge because the International Space Station has had a radiator which dissipates lots of heat already.
