I.'ve never heard a quarter of a corporation having positive cash flow as any kind of business metric. Of course, since Starlink and SpaceX are subject to completely weird accounting standards (including providing software assistance to Twitter for free, and other shenanigans in the accounting world according to Musk), it could mean anything. I worked with Iridium and Motorola during the phase before it was sold for scrap to the DoD, essentially. What's fascinating is how "creative accounting" between then and the current Starlink continues to persist. Motorola's Chris Galvin was a lot like Musk w.r.t. not seeing clearly what was happening - he was isolated by sycophants who really wanted to believe that there was a business there. Then later Motorola completely screwed up its cellular tech business by betting against GPRS and the Europeans. Should have hedged and participated in the rapid cellular industry growth, but instead, basically drove a great tech company into the ground. As a I watch Starlink and SpaceX play a shell game with their business economics, it's fascinating to watch a similar thing play out. Especially watching the "fan boys and girls" get taken for a ride as the Iridium "fan boys and girls" did - including stunts like showing that you could make a phone call from Mt. Everest, as if that was gonna fix the underlying lack of business strategy for success. The current version of this "fan thinking" is the idea that somehow the satellites can route packets among themselves and provide a low-latency, high-quality Internet access service. As Dave Taht points out, we don't see the customer churn rates as people discover the bufferbloat effects as the customers scale, and which are largely designed into the Starlink systems architecture (the satellites' packet routing architecture). But yeah, we might send a few people to Mars to die there. [-- Attachment #2: Type: text/html, Size: 4344 bytes --] ^ permalink raw reply [flat|nested] 9+ messages in thread

I.'ve never heard a quarter of a corporation having positive cash flow as any kind of business metric. that it earns more money than it spent in that 3 month period, and expected to do the same in 2023. SpaceX is private (so it doesn't have to impress the Wall Street clueless folks), it deosn't get 'cost plus' contracts. There is far less incentive to do creative accounting than if either of these were true.

The "v2" satellites already constructed are effectively already obsolete, and their technologies being shrunk down into the v2 minis and successors, and the network behaviors themselves continually optimized. Right now I think it will be 2+ years before the first meaningful launch of the larger starlink satellites on Starship, and at the same time the flight rate of the falcons keeps getting better and better. I would kind of expect the "v3 mini" to have roughly the same throughput as the v2s at an ongoing half the size. Starlink is now well over a billion dollar a year revenue business, which is insanely better than what iridium achieved before entering bankruptcy (Iridium was under 70k users as best as I recall around then). Whatever spacex and starlink are spending on R&D makes me shudder. I am finding it odd that they have stopped publishing user growth numbers - small personal data point: in working with libreqos users, I am hearing about a 40% rate of folk that switched from WISP to starlink and back - so customer retention might be a problem as soon as someone finds a better service elsewhere. Another number I am trying to track is the useful life of the v1s - projected to last 5 years. There are 70+% of the first launch still operational.
