AZURE Vapor Tracers over Norway
Explanation: What's happening in the sky? The atmosphere over northern
Norway appeared quite strange for about 30 minutes last Friday when colorful clouds, dots, and plumes suddenly appeared. The colors were actually created by the NASA-funded
Auroral Zone Upwelling Rocket Experiment (AZURE) which dispersed gas tracers to probe winds in Earth's
upper atmosphere.
AZURE's tracers originated from two short-lived
sounding rockets launched from the
Andøya Space Center in Norway. The harmless gases,
trimethylaluminum and a
barium/
strontium mixture, were released into the
ionosphere at altitudes of 115 and 250 km. The vapor
trails were observed dispersing from several ground stations. Mapping how
AZURE's vapors dispersed should increase humanity's understanding of how the
solar wind transfers energy to the Earth and powers
aurora.
