The Cusp Alfvén and Plasma Electrodynamics Rocket-2, or CAPER-2, mission launched aboard a NASA Black Brant XII sounding rocket from the Andøya Space Center in Norway on Jan. 4, 2019.

CAPER-2 flew through active aurora borealis, or northern lights, to study the waves that accelerate electrons into our atmosphere. The mission is the third of nine missions scheduled through 2020 as part of the Grand Challenge Initiative – Cusp, an international campaign to explore the northern polar cusp.

For CAPER-2 scientists, flying through an aurora provides a peek into a process as fundamental as it is complex: How do particles get accelerated throughout space? NASA studies this phenomenon in an effort to better understand not only the space environment surrounding Earth — and thus protect our technology in space from radiation — but also to help understand the very nature of stars and atmospheres throughout the solar system and beyond.
