Auroral Spatial Structures Probe

ASSP was launched on January 28, 2015 from Poker Flat, Alaska into active aurora during geomagnetically-active conditions. To better understand global temperature changes in the thermosphere, data from the ASSP mission will be combined with ground-based observations of winds, large electric field patters, and auroral images to improve understanding of Joule heating and its effects.

ASSP consisted of a constellation of six small payloads that were ejected from a sounding rocket in mid-flight as well as one main payload with a suite of instruments. SDL designed, built, and tested the six sub-payloads.
