Since then Harrison's "Pandora's box" of balloon-borne sensors has gone from strength to strength. It has helped with projects from detecting ash from the Icelandic volcano during the flight ban to measuring charge on dust plumes from the Sahara. Ultimately this nifty box of tricks could include optical detectors to help firm up cloud measurements or high-energy particle detectors to check on space weather.
