SpaceX and Elon Musk.
If that isn't the biggest, fattest, most expensive, most dramatic, most promising and most disappointing paragraph in history then I don't think you read it correctly.
I'm going to share some thoughts on Starlink - because it is the money driver of the SpaceX float. Pretty much everything else is a money-pit of hype and wild promises.
I'm frankly alarmed at the lack of thought on detail and planetary impact for this largest float in history. But my financial planner persona just looks at such alarm with mild bemusement - this is the sort of stuff that happens at the tail end of bull markets. Still, it is alarming.
Let's look at just a few small areas of this massively large public float of a set of private companies in the United States.
Starlink has been a brilliant financial and technological success. All the benefits of the internet being made available to all those people who didn't have tidy access before. Personally, I'm not entirely certain the world needed that sort of carpet blanketing of a technology that has turned out to be an incredibly destabilising and distorting influence on society. The internet has brought wonderful technology advances but also a trail of dysfunctional social problems. And we land-based humans have now managed to turn our upper atmosphere into a parking space for rubbish on a scale that just grows and grows. Both SpaceX and Jeff Bezos' Blue Origin have plans for tens of thousands more satellites to be sent into the that space rubbish tip. If you think I'm being dramatic, look it up. No - that's unfair of me. We're all too busy to look up such inane stuff. So I'll do it for you..
Dear Gemini, how long do internet satellites last?
Gemini answer ...
Starlink and similar Low Earth Orbit (LEO) internet satellites operate with an average planned lifespan of 5 years. Rather than being repaired, they are deliberately replaced on a rolling cycle, burning up harmlessly in the Earth's atmosphere at the end of their useful life.
Michael's response is not really printable here but roughly translated means 'how can you say the burning of tens of thousands of satellites in our upper atmosphere is harmless?'
Gemini answer ...
It is definitely an intense phrase, but this process is actually an intentional safety feature designed to protect the planet [1, 2].Why They Burn UpMassive Speed: Satellites travel at over 27,000 kilometres per hour in Low Earth Orbit [1].Extreme Friction: When dropping into the denser air of the lower atmosphere, this speed creates immense friction [1].Intense Heat: The friction generates temperatures reaching up to 1,650 degrees Celsius [1].Vaporisation: This heat acts like a cosmic incinerator, turning the satellite into harmless vaporised dust and gas [1].Why This Is DoneNo Space Junk: Leaving dead satellites in orbit creates a field of dangerous space debris [2].No Ground Impacts: Starlink satellites are specifically designed to be "fully demisable" [1].Complete Melting: They use materials like aluminium that completely melt away, leaving nothing solid to hit the ground [1].
Sounds perfectly fine, doesn't it? Everything has been sorted out and worked out so that this is a perfectly safe and logical thing to do. Or is it?
Michael asks how this space rubbish tip can possibly be 'harmless' or 'safe'?
Gemini answer ... and we are finally getting down to a "human" look at this issue, and not a profit look at this issue.
You are completely right to call that out, and your frustration is shared by the global scientific community. It was a massive oversight to treat the upper atmosphere as an invisible, "harmless" incinerator.While "burning up" prevents heavy chunks of metal from falling onto towns and houses, it does not magically make the material disappear. It just changes its form from solid machinery into vaporised chemical pollution trapped high above the planet.The Chemical Fall-OutWhen a Starlink or similar internet satellite vaporises, its components break down into highly reactive metallic dust:Aluminium Oxide (Alumina): Satellites are mostly made of lightweight aluminium. Re-entry turns this into alumina nanoparticles. Studies show these particles act as catalysts that destroy the ozone layer, reversing decades of global recovery efforts.Exotic Heavy Metals: Air samples taken by NOAA research flights have detected high levels of lithium, titanium, copper, and lead floating in the stratosphere. These metals mirror the exact high-performance alloys used in the aerospace industry.The Scale of the ProblemThe main reason this is causing panic among atmospheric scientists is the sheer volume:Then vs. Now: Historically, a few dozen satellites or spent rocket stages re-entered the atmosphere each year. Now, with SpaceX operating thousands of satellites on 5-year lifespans, one to four Starlink satellites are burning up every single day.The 2030 Horizon: Experts warn that by the end of the decade, as companies like Amazon Kuiper launch their competing networks, several tonnes of spacecraft material will be vaporised into our atmosphere daily.Climate Alteration: Scientists at organizations like the National Oceanic and Atmospheric Administration (NOAA) warn that by 2040, the amount of human-made metallic dust floating in the stratosphere will equal the natural dust left behind by falling meteors. They fear this "accidental geoengineering experiment" could alter polar wind speeds, trap heat, and affect global temperatures.The Regulatory Blind SpotThe most alarming part of this situation is that there are currently no international laws or regulations governing atmospheric pollution from re-entering spacecraft. Companies were granted permission to launch mega-constellations because the satellites didn't leave physical "space junk" in orbit. The fact that they were turning the upper atmosphere into a chemical dumpsite was simply ignored until recently. Governments and independent researchers are currently scrambling to set up monitoring frameworks to force space companies to change how they build and retire their hardware before the damage to the upper atmosphere becomes permanent.
So there you have it. The only profitable part of this public listing of a set of private companies in the USA is a business devoted to turning our upper atmosphere into the same mess as our lower atmosphere.
You may have some sort of environmental or financial or business or social scruples. If you do, then you still won't be able to easily avoid being part of this 'world's largest ever float' because every global index fund will be forced to buy shares in this company. Australia will become a large shareholder of this business. Not large from the USA point of view, but a large part of our national dollar pool will be invested into this company.
There is this concept in financial planning, called "informed consent". The need to ensure that a person understands the scope and scale of what is being recommended to them. And given the unequal balance of knowledge, training and experience, the responsibility sits with the Adviser to ensure their client has an appropriate level of understanding of whatever is being proposed. If you try and apply this level of care to something like the SpaceX float, you'll just get a tad disappointed. The float will make a small pod of people billionaires and a slightly larger pod of people millionaires and it's likely to create a vortex of excitement and hype capable of lifting markets more widely. Wonderful stuff.
But just remember that this is a loss-making company selling hype and promises barely plausible for a thinking individual. There's obviously money to be made, but the interesting point for me is whether this company will make it into the portfolios of investment funds oriented towards Environmental, Social and Governance (ESG) mandates..?
Only time will tell.
