I am the Principle Investigator for the NASA Auroral Spatial Structures Probe (ASSP), a 70-foot, four-stage unmanned rocket loaded with scientific instruments sitting on the launch pad now in Alaska. After four years of planning, building and testing at NASA Wallops Flight Facility and at the Utah State University Space Dynamics Laboratory, it is all coming down to a call, my call, as to when to launch.
The aurora borealis is beautiful, awe-inspiring, and far more dynamic and crisp than pictures seem to capture.
