Every answer and its explanation appears here once you have finished the path. Each one then links to the matching glossary entry, where the concept is set out in full with its worked example.
1. A single launch carries five satellites belonging to five different operators, all insured with the same insurer. What does that configuration create for it?
An accumulation, since one instantaneous event can destroy all five risks at once
The launch phase, from engine ignition through separation and initial positioning, concentrates a major share of space risk: a failure destroys several hundred million in an instant, with no recourse and no salvage. A shared ride therefore loses several satellites on one event, which is why accumulation management belongs to launch underwriting just as much as technical expertise on launchers and mission profiles. The market is narrow and concentrated on a handful of specialist insurers and reinsurers, which makes it violently cyclical: a run of failures can consume several years of premium.
Glossary entry →2. An operator is offered a markedly cheaper slot on the very first commercial flight of a new launcher. What does the actuarial cost say about that saving?
It is unfavorable, since failure rates are structurally higher on early flights, which is paid for in premium
A maiden flight has no reliability history of its own, and design, integration or procedural defects typically surface on the first real flights, under conditions that ground simulation does not fully reproduce. Ariane 5's maiden flight, on June 4, 1996, ended in self-destruction thirty-seven seconds after liftoff following a guidance software error, destroying its payload. The loading then falls quickly with each successful flight until it converges on general market rates. The saving made on the slot is therefore paid back in premium, and some operators simply hold their most valuable payload back until the vehicle has a few successes behind it.
Glossary entry →3. A satellite is destroyed by its launcher's failure, and the investigation attributes the defect to the launcher. Whom does the satellite operator turn against, under a standard launch contract?
Against nobody, since the cross-waiver bars any recourse, and it relies on its own property cover
The cross-waiver is a standard clause: each party, the authorizing state or agency, the launch provider, the satellite operator and its customers, waives all recourse against the others for damage it suffers in connection with the launch, regardless of fault. Several national frameworks make it a license condition, in the United States since the Commercial Space Launch Act of 1984. The point is to keep every incident from turning into a long dispute over apportioning fault among interdependent technical parties, in an activity where the cause can stay disputed for months. The consequence for the operator is direct and rarely anticipated: the clause moves its entire risk onto its own property cover, with no safety net if it is underinsured.
Glossary entry →4. On September 1, 2016, while a Falcon 9 was being fueled ahead of a static fire test, the launcher's explosion on its pad destroyed the Amos-6 satellite, insured for roughly 200 million dollars. Why does the payout not come from the operator's launch policy?
Because the satellite, not yet launched, fell under the manufacturer's pre-launch policy, paid before the operator
A launch policy usually attaches at intentional ignition: a satellite destroyed on the pad, during fueling and before the test, has not yet entered it. Amos-6 had not yet been delivered to Spacecom, and the all risks pre-launch policy of its builder, Israel Aerospace Industries, responded. Spacecom did not trigger its launch policy, whose premium was to be returned, and announced in November 2016 that it would receive 196 million dollars, the price paid for the satellite, through the manufacturer. Settlement did not wait for the cause: SpaceX only named the failure of a pressurized helium tank in January 2017, which rules out the anomaly investigation answer. The 1972 Liability Convention addresses damage caused to third parties, not the loss of the operator's own satellite, and nothing suggests capacity ran short. For the underwriter, the lesson is about risk transfer: the moment title passes and the moment the launch policy attaches must meet without leaving a gap, and the aftermath showed it, since IAI went on to sue its own insurers over the balance.
Glossary entry →5. A satellite loses part of its transponders and sees its useful life shortened, but keeps transmitting. What does a space policy provide?
A partial loss scale, and beyond a cumulative degradation threshold, a constructive total loss
Few space failures are as clean as a launch explosion: gradual degradation is the norm. The policy therefore sets a scale, often a percentage of insured value, computed on lost capacity or on the shortening of useful life against what was assumed at underwriting. A cumulative degradation threshold, generally around half the capacity or value, qualifies as constructive total loss: the insurer settles as for a total loss and takes over the degraded asset where relevant. The propulsion leaks affecting several Boeing 702SP satellites between 2017 and 2019 were settled as partial losses indexed on lost service life, the satellites continuing to operate. Without this mechanism the insured would have to choose between keeping a diminished asset for nothing and giving up a satellite that still renders service.
Glossary entry →6. In-orbit insurance is generally renewed each year, over the satellite's whole life. How does its risk differ from launch risk?
Total losses are rarer, but partial failures raise far more complex valuation questions
In-orbit insurance covers failures during operational life: payload failure, solar array failure, premature propellant depletion, component degradation, or destruction by debris. Total loss frequency is lower than at launch, but partial failures, which reduce capacity without destroying the satellite, open the valuation question that the partial loss clause exists to settle. Underwriting it means following the technical health of each insured satellite, reading experience by platform and by component, and factoring in the continuing degradation of the orbital environment. Together with launch insurance it forms the core of space asset cover.
Glossary entry →7. On February 10, 2009, the active satellite Iridium 33 struck the defunct Russian satellite Kosmos 2251 at more than eleven kilometers per second, generating around 2,000 pieces of trackable debris. What distinguishes that loss from an internal failure, for an insurer?
It combines a total loss, liability toward the owner of the object struck, and accumulation through the debris it creates
A relative speed above ten kilometers per second is enough to destroy both objects entirely. Unlike an internal failure, this peril depends on object density at a given altitude and on the quality of conjunction tracking, that is, on forecasting an approach early enough to maneuver: satellites with propulsion maneuver more and more often, the others stay fully exposed. And the debris cloud often persists for years, degrading the orbital environment for every operator at that altitude, far beyond the two parties directly hit. That third layer is what makes a collision an accumulation event rather than simply a large single loss.
Glossary entry →8. A satellite in orbit is damaged by a space object belonging to another state. What must its owner establish to engage the launching state's liability under the 1972 Convention?
Fault, since absolute liability applies only to damage on the ground and to aircraft in flight
The 1972 Convention specifies the principle of state responsibility laid down by the 1967 Outer Space Treaty, and it establishes two distinct regimes. On the ground and for aircraft in flight, the launching state is absolutely liable, with no fault to prove. In orbit, for damage caused to another space object, liability instead requires fault to be established. That dividing line structures the whole legal treatment of collisions and re-entries, and it is decisive for insurance since it says who answers and under what standard, which shapes the liability covers required of operators. The regime was written in an era of light space traffic, and orbital congestion could call on it far more than it ever has.
Glossary entry →9. What changes, for an underwriter, between a single satellite and a constellation of several thousand craft?
The analysis moves from the single object to a population of interdependent objects, where a serial defect hits the whole fleet
The orbital congestion the model generates raises collision probability, and a collision produces debris that can feed a runaway effect, the Kessler syndrome, threatening every object in orbit. Accumulation then changes nature: a serial defect on a model produced in large numbers, or a degradation of the orbital environment, can hit an entire fleet at once. Add the growing dependence of critical services on these constellations, which installs a systemic risk in the event of mass failure. The underwriting question is therefore no longer the price of one satellite but the aggregate severity of a population, and the open point is whether that fits inside the capacity of the traditional space market.
Glossary entry →10. The loss of the Amos-6 satellite, insured for roughly 200 million dollars, on its own consumed a significant share of the world space market's annual premium. What does that ratio say about the market's structure?
That a single loss weighs a notable fraction of sector premium, which makes reinsurance structural rather than optional
Worldwide direct space insurance capacity is narrow and concentrated on a limited number of specialist players. Without reinsurance, an isolated insurer could not absorb the total loss of a large telecommunications satellite without putting its solvency across every other line in question. Reinsurers come in mostly on excess of loss, taking the share of a loss above a threshold, or on quota share across a whole portfolio. And because the market is both small and strongly correlated, a heavy year, for example a run of launch failures close together, hardens direct insurance and reinsurance at the same time, with a lag of several months between the loss and treaty renewal that amplifies the sector's own cycle.
