On Cupid! On, Donner and BARREL!

Four reindeer walk past the BARREL payload on the launch pad at Esrange Space Center near Kiruna, Sweden. The BARREL team was at Esrange Space Center launching a series of six scientific payloads on miniature scientific balloons. The NASA-funded BARREL – which stands for Balloon Array for Radiation-belt Relativistic Electron Losses – primarily measured X-rays in Earth’s atmosphere near the North and South Poles. via NASA https://ift.tt/sXAuveB
