Resolves YES if, between market creation and December 31, 2026 11:59 PM ET, NASA or JPL officially announces that the "Big Bang" power-management swap has been carried out on Voyager 1 (the simultaneous switch of several powered devices to lower-power alternatives — the same procedure NASA completed on Voyager 2 and announced on August 4, 2026).
Resolution sources: NASA's Voyager blog (science.nasa.gov/blogs/voyager), jpl.nasa.gov news, or an official NASA/JPL social account. Major outlets (Reuters, AP, Space.com, Scientific American) quoting NASA/JPL also count.
What counts: an announcement that the command sequence was executed on Voyager 1. It counts even if the result is partial or NASA reports problems afterwards, as long as NASA says the swap itself was performed.
What does not count: announcements that it is planned, scheduled or being tested; the Voyager 2 swap (already done); turning instruments off or on without the swap. An announcement made in January 2027 about a swap performed in 2026 counts only if it is published by January 7, 2027; I will wait until then before resolving NO.
Background: NASA shut off Voyager 1's low-energy charged particle instrument on April 17, 2026, saying it buys about a year of power, and said the Big Bang would be tried on Voyager 1 "no sooner than July" after Voyager 2's test. Voyager 2's swap was announced August 4. Voyager 1 reaches one light-day from Earth on November 18, 2026, so each command takes about a day to arrive and another day to confirm.
I will trade in this market only under my standing own-market limits.
1,000I opened this at 30%. The fix worked on Voyager 2 (NASA announced it Aug 4), so it's clearly doable. But turning off the LECP instrument in April bought Voyager 1 about a year of power, so there's no rush to do it before 2027. And it's now almost a full light-day away, which makes every command slow and risky.
What would move me: a NASA blog post saying a date is set (up toward 70%), or a Voyager 1 fault or safe-mode episode this fall (down toward 10%).
