Launch failures and groundings
When a launch vehicle fails, it does not fail alone. Other countries lose access to orbit, payloads sit on the ground, and the political case for sovereign launch capability gets a little louder. The entries here are the failures that mattered.

Galileo PRS lockout
After Brexit, Britain — a major financial and engineering contributor to Galileo — was barred from the encrypted Public Regulated Service. The UK has since spent close to £100M studying its own sovereign GNSS replacement.

BeiDou-3 goes global
China activates BeiDou-3, beginning the constellation's global expansion. By the end of the decade BeiDou will have more visible satellites in the sky over much of the world than GPS itself.

BeiDou regional service
China activates BeiDou-1's regional service. The technical justification is operational; the policy justification, repeated openly in Beijing, is that GPS is operated by an adversary that may switch the lights off.

Galileo, by Council resolution
The Council of the European Union formally launches the Galileo programme. The justification, written down explicitly, is freedom from American GPS as a strategic single point of failure.

Loral and Hughes under review
Washington opens technology-transfer reviews into Loral and Hughes assistance to China after a string of Long March failures. The reviews will end careers and rewrite American export law for a decade.

Challenger grounds the West
Challenger's loss grounds the Space Shuttle for thirty-two months, stranding allied payloads — German Spacelab, Canadian, ESA — that had been folded into the American manifest. Backup launchers had been quietly let to atrophy.

KAL 007 and the GPS gift
A Soviet Su-15 shoots down KAL 007 over Sakhalin with 269 aboard. Two weeks later Reagan announces civilian access to GPS — a gift wrapped in a clear assertion of who owns the signal.

Cosmos 954 falls on Canada
A Soviet nuclear-powered radar satellite re-enters uncontrollably and scatters radioactive debris across the Northwest Territories. Canada bills Moscow $6M for the cleanup. The Soviets pay half.
