Named after the Monkey King of Chinese legend who can see demons in disguise, DAMPE hunts for dark matter — the invisible substance making up 27% of the universe that has never been directly detected. In its first 530 days, it recorded 1.5 million high-energy cosmic ray electrons and positrons with the highest energy resolution of any space instrument. In 2026 it published a landmark result in Nature: direct evidence for a 'cosmic speed limit' on particle acceleration near Earth, rewriting cosmic ray physics after a century of uncertainty.
