![Four reindeer walk past the BARREL payload. Two are on the left of the payload and two are on the right. The payload looks like a large white box with red square patches on two sides, resting atop a platform with four wheels. The ground is brown with small rocks, and in the background, a forest of green trees spreads over hills in the distance. The sky is overcast.](https://www.nasa.gov/wp-content/uploads/2023/12/gsfc-20171208-archive-e000249orig.jpg)
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.
