Space Sovereignty — incident
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.
Space Shuttle Challenger breaks apart 73 seconds into the STS-51-L mission on 28 January 1986, killing all seven crew. The Shuttle fleet is grounded for 32 months while the Rogers Commission investigates and the solid-rocket-booster programme is rebuilt.
Allied payloads that had been folded into the American manifest — German Spacelab modules, Canadian instruments, ESA missions — are stranded. Several agencies that had let backup launchers atrophy spend the rest of the decade rebuilding indigenous launch options. The lesson, rarely stated aloud but everywhere absorbed, is that an entire continent's space programme should not depend on one launcher operated by one country.
