National licensing and space law
Before a satellite can fly under a national flag, the state must authorise, supervise and insure it. This page covers the legal scaffolding: launch-state obligations, national space legislation, UN registration and liability insurance.
The treaty layer most first-time programmes discover too late
Five UN treaties govern outer space. For a first-time space nation, two dominate practical planning. The 1967 Outer Space Treaty establishes that states bear international responsibility for national activities in space, whether carried out by government or private actors. The 1972 Liability Convention makes the launching state absolutely liable for damage caused by its space objects on the surface of the Earth, and liable on a fault basis for damage in orbit. These are not abstract obligations. They mean that if a state's registered satellite collides with another object and causes damage, the government is the defendant, not the operator.
The 1975 Registration Convention adds a further duty: every space object must be registered with the launching state and the details notified to the UN Secretary-General. The UN register is public. Omitting registration does not make a satellite invisible; it makes the state non-compliant and the satellite legally ambiguous in any future liability dispute. Small nations sometimes assume these conventions apply only to major space powers. They apply to every signatory, and the practical consequences of non-compliance fall hardest on states with the least diplomatic capital to spend defending themselves.
National space legislation: what the law must actually say
A state cannot authorise a private satellite operator simply by signing a contract. It needs domestic legislation that creates a licensing authority, defines the scope of authorised activities, sets supervision requirements and establishes a liability and insurance regime. Without this, a private operator has no legal basis to fly under the national flag, and the state has no mechanism to discharge its treaty obligations. As of 2024, roughly thirty states have enacted dedicated national space legislation; many more have satellites on orbit without it, which is a legal exposure, not a technicality.
The minimum viable legislation covers four things: a licensing regime for space activities (launch, operation, re-entry), a supervisory framework giving the licensing authority ongoing oversight of licensed operators, a liability and indemnification chain between operator and state, and a registration procedure that feeds the UN register. Some states add provisions on remote sensing, data policy and orbital debris mitigation. The debris mitigation rules matter operationally: the Inter-Agency Space Debris Coordination Committee (IADC) guidelines, while not legally binding, have been incorporated into the licensing conditions of most major launch states, meaning a satellite that does not meet them may not get a launch slot regardless of what the home state's legislation says.
Launch-state status and why it is a negotiated outcome
The launching state under the Liability Convention is defined as the state that launches, procures the launch, or from whose territory or facility the launch takes place. A satellite can have multiple launching states simultaneously. This matters because liability exposure and registration obligations attach to each launching state. When a small nation procures a launch from a commercial provider using a foreign rocket from a foreign range, it is typically a launching state by virtue of procuring the launch, not by virtue of owning the rocket or the range.
Launch service agreements from providers such as SpaceX, Rocket Lab or Arianespace include provisions about liability allocation and insurance requirements, but these are commercial arrangements between the operator and the launch provider. They do not extinguish the state's international liability. The practical consequence: before signing a launch service agreement, the procuring state needs to know whether its national legislation is in force, whether its insurance requirement is met, and whether its registration procedure is ready to file within the timeframe required. Getting the sequence wrong means launching legally exposed.
Insurance: the number that concentrates political attention
Third-party liability insurance is the mechanism by which states transfer the financial risk of their Liability Convention exposure to the insurance market. Most national space laws require operators to hold a specified minimum level of third-party liability cover as a condition of their licence. The figures vary considerably by jurisdiction. The United Kingdom's Space Industry Act 2018 sets a cap on operator liability to the state at sixty million pounds for most missions, with the state retaining exposure above that level. Australia's Space (Launches and Returns) Act 2018 requires insurance cover of up to three billion Australian dollars for certain launch activities. These numbers are set by national policy, not by the treaties themselves, which impose no financial cap on state liability.
For a first-time space nation establishing its own licensing regime, the insurance requirement is a genuine policy decision with fiscal consequences. Set it too low and the state retains unhedged liability exposure. Set it too high and no commercial operator can afford to be licensed, which defeats the purpose of having a regime. The insurance market for satellite third-party liability is relatively small and specialist; underwriters will want to see mission details, orbital parameters, debris mitigation compliance and operator track record before quoting. A state that has not yet enacted legislation has nothing to show an underwriter.
Where the process genuinely breaks down
The most common failure mode is sequencing. Legislation takes time: drafting, legal review, parliamentary passage and entry into force can easily consume eighteen to thirty-six months in a state with a functional legislature and no competing priorities. A programme that sets a launch date before legislation is enacted is building on sand. The satellite can be built on schedule; it cannot legally fly under the national flag until the legal framework exists.
A second failure mode is institutional capacity. Legislation that creates a licensing authority is only as useful as the authority's ability to actually assess licence applications, conduct ongoing supervision and respond to incidents. Many first-time space nations draft licensing regimes that assume a permanent, technically competent space agency exists to run them. If that agency does not yet exist, or exists only on paper, the legislation is inoperable in practice. The licensing authority needs at minimum the ability to evaluate orbital debris mitigation plans, assess insurance adequacy and maintain the national register. These are not trivial technical tasks.
A third limit is jurisdictional reach. National space legislation governs operators licensed in that state. It does not govern a foreign operator who launches a satellite that interferes with the national satellite in orbit. The Liability Convention provides a remedy in principle; in practice, pursuing a liability claim against a foreign state is a diplomatic and legal process that can take years and requires evidence that is often unavailable. No domestic licensing regime solves this problem.
The practical sequence for a first-time space nation
The sequence that works: assess treaty status first (which conventions has the state ratified, and what reservations if any), then draft legislation with the licensing regime, liability chain and registration procedure, then establish or designate the licensing authority, then develop the insurance requirement in consultation with the insurance market, then begin accepting licence applications. This sequence takes time that programme planners often do not budget for.
Registration with the UN Office for Outer Space Affairs (UNOOSA) is administratively straightforward once the national framework is in place. The state submits the required particulars: name of launching state or states, designator or registration number, date and territory of launch, basic orbital parameters and general function. UNOOSA publishes these in the online register. The submission itself is not the hard part. Having the legal authority to make it, and the national record-keeping to support it, is where first-time states consistently underestimate the work involved.
