Two NASA sounding rockets launched into auroras over Alaska last week to study the impact that these geomagnetic light shows have on Earth 's upper atmosphere.

The two rockets released vapor tracers and pressure sensors at different heights across central and northern Alaska during a sudden auroral substorm, which is a sudden, brief, and explosive intensification, or brightening, of an aurora.

The third rocket is expected to launch additional tracers, which must be released during dawn hours .
