Introduction	From April to May 2023, the superBIT telescope undertook a mission, carried into the Earth's stratosphere by a helium-filled super-pressure balloon. Its purpose was to collect astronomical imaging data from an altitude above 99.5% of the Earth's atmosphere. Launched from New Zealand, the balloon operated for 40 days, completing five circumnavigations of the globe within latitudes of 40 to 50 degrees South. Four 'DRS' (Data Recovery System) capsules were attached to the telescope, each equipped with 5 TB of solid-state data storage, a GNSS receiver, an Iridium transmitter, and a parachute. Telescope data were duplicated onto these capsules, with two subsequently released over Argentina. These capsules drifted 61 km horizontally during their 32 km descent. Despite high-speed, gusty winds and local topography, which introduced an irreducible discrepancy below 2 km, their descent vectors were accurately predicted within 2.4 km. Upon landing, the capsules transmitted their precise locations within a few metres. All superBIT data were successfully retrieved from these capsules, even though the main telescope sustained damage upon its landing.
