I look at Starlink where currently about 6 spacecraft deorbit a week and need replacement as a huge operational cost. Many SpaceX launches are Starlink launches, it raises the question of whether this is a circular or self fulfilling industry.
An analysis from early 2025 showed that the median life expectancy of a 1st generation Starlink satellite was 5.3 years, though expected to improve in v2 and v3.
Beyond that, the solar lifecycle means that every 11 years the earth’s orbit expands increasing drag on low-orbit satellites (which brings them down) as well as bombarding them with more radiation (increasing the likelihood of failures).
Other sources I’ve found in searching for it give their median life-expectancy as being 5-7 years.
Land-based telecom operators don’t have to replace pretty much all of their transmission infrastructure - worse, in a costly to access location - more than once a decade.
Space-based tele-communications is more than proven as a viable business model, what’s nowhere near proven (or anywhere close to being mathematically demonstrable) is one single operator of those being worth more than many major land-based telecom operators each with many times the number of customers of that space-based telecoms business and providing much faster network access (somebody else gave Deutsche Telecomm as an example) put together.
(How exactly in terms of actual PHYSICS will Starlink deliver via radio waves to for example all 245 million European households - necessary to justify such valuations - a reliable 1Gbps connection for €10/month needed to to beat the land operators?)
SpaceX’s IPO valuation which itself is mostly anchored on Starlink, is totally unjustified and unjustifiable by fundamentals.
Unless you want to separate starlink from spacex it’s kinda the other way around.
I think spacex was adding starlink deployment to all their rockets and their “plan” was to launch other satellites and nasa projects, then get the starlink stuff up there for less.
Its actually a great business model as they need to do actual test flights to build better rockets and instead of that being pure R&D expenses, its supplemented by launching Starlink satellites which generate their own revenue for the company.
Great theory, but the Falcon 9 is already a proven design and most of SpaceX’s R&D is going to the starship, which uses completely different engines and which has blown up or disintegrated just as much as its successfully gotten above the atmosphere. It’s also never actually completed an orbit or delivered a gram of anything to orbit.
Starlink is a useful tool to boost launch numbers precisely so investors think things are better than they actually are. Originally SpaceX burned through government and private investor money. Now that they’ve blown through the entire Artemis budget the interim director of nasa gave them through blatant corruption, and launched even more billion dollar fireworks using private investor money, they are desperately trying to convince the public for more fireworks funds.

As far as I understood, I always thought that they just used other people’s rockets to piggyback their own satellites to space basically for free

Haven’t heard that though you need a lot of other launches with space available….

I suppose that it is that dependence upon Starlink to boost launch numbers makes me suspicious of the books. The whole thing just feels ponzie scheme.
