AZURE Sounding Rockets’ Colorful Flight

During their flight over Norway on April 5, the two AZURE sounding rockets deployed gas tracers — made of substances similar to those in fireworks — to create colorful clouds that allow researchers to track the flow of neutral and charged particles with the auroral wind. This helps scientists better understand the exchange of energy within an aurora.


AZURE is one of nine missions launching as part of the Grand Challenge Initiative — Cusp, a series of international sounding rocket missions to study Earth’s geomagnetic cusp between 2018 and 2020. The cusp is one of the few places on Earth where particles from the solar wind have easy access to our atmosphere.
