US Military grants SpaceX restricted space tracking data access

The Lighthouse Keeper’s Favourite Ship

The debate is framed as state versus market: either the US military keeps its restricted space tracking data behind the fence, or it hands the keys to SpaceX and lets the most capable company run the sky. But the real object here is a shared resource, the orbital commons of low Earth orbit and the knowledge of what is moving through it. The question is not who should own that knowledge. It is who actually uses the orbits, and whether those users can govern them together.

Begin with the resource itself, because it has an awkward property. An orbit is subtractable: a satellite occupying a shell, or a fragment of debris crossing it, reduces what remains for everyone else. It is also hard to exclude anyone from. Nobody fences an altitude. Those are the textbook marks of a common-pool resource, the same marks I found in mountain pastures and irrigation canals. The data that tracks these objects is the monitoring system of that commons. In a fishery, the people who count the catch hold a quiet kind of power, because whoever sees the stock first can fish it first.

That is why this arrangement deserves more scrutiny than the national-security framing gives it. The concern most often raised is that SpaceX gains an edge over its competitors, and that is a fair concern. The deeper problem is institutional. When one user of a commons receives better monitoring than the others, the monitoring has stopped being a shared good and become a private advantage. Monitoring is only one of the conditions under which communities successfully govern shared resources, but it is the one the others depend on. Rules nobody can verify turn into suggestions, and sanctions nobody can see the grounds for come to look like favouritism.

Consider the strongest case for the decision, and it is a serious one. SpaceX flies a very large share of the active satellites in low orbit. If any operator’s manoeuvres determine whether the commons stays usable, it is this one. On that reading, handing restricted data to the actor with the most hardware in the sky is not favouritism. It is putting the information where the collision risk is concentrated. A ministry official could reasonably argue that safety is served faster this way than by waiting for an international consensus that may never arrive.

I take that argument seriously. It nonetheless confuses the largest user with the whole community of users. The irrigators I studied did not give the biggest landowner the only key to the sluice gates, however many fields he had. They gave the keys to a tribunal on which the small farmers also sat, because they had learned that whoever reads the water levels alone will, given enough dry summers, eventually read them in his own favour. I am not attributing any such intent to SpaceX. The events reported here do not tell us its motives, and a plain safety rationale is entirely plausible. The point is structural. An arrangement whose fairness depends on the good character of one firm has no protection against the day that character changes, the ownership changes, or the competitive pressure rises.

A polycentric map of this sky looks very different from the binary in the headlines. It has military trackers, commercial tracking firms with their own sensors, national space agencies, insurers who price collision risk, academic observers, and dozens of smaller operators who cannot afford their own radar. Each is a centre of decision with partial sight. A well-governed orbital commons would let these centres check one another: shared conjunction data at an agreed standard of accuracy, a forum in which disputes over manoeuvres are heard, and graduated consequences for operators who ignore warnings. What the reported arrangement does instead is make one channel more privileged, between one agency and one company. It does not add a new centre of governance. It narrows the field of sight.

Here the humour writes itself, though it is not kind. We have a lighthouse that has served every ship in the channel for decades. The keeper now hands a sharper fog chart to the shipping line with the most vessels, on the reasoning that it has the most to lose. Every other captain is reassured that this improves safety in the channel. In a narrow sense it does. The trouble is that the next time the fog comes in, the other captains will be steering by a chart they know is second-best.

Picture an engineer at a small satellite company, alone at three in the morning, with a conjunction warning on the screen. She has to decide whether to burn scarce fuel to dodge an object. Somewhere else, a competitor is looking at the same object with better data.
