Plasma Wave and Electron Density Structure Observed in the Cusp with a Dual-Rocket Experiment
abstract SM13A-1659 The Twin Rockets to Investigate Cusp Electrodynamics (TRICE) were launched on December 10, 2007, from Andoya Research Range in Andenes, Norway, into the active cusp. Both payloads traveled north over Svalbard, with one payload reaching an apogee of ~1100 km, and the other reachin...
