45.005 Terrier-Oriole and 46.001 Terrier-Improved Malemute were launched from Kwajalein, Marshall Islands on May 7, 2013. The scientific objective of the Equatorial Vortex Experiment (EVEX) mission is to validate/falsify models of post-sunset electrodynamics via direct measurements of their drivers, specifically zonal winds. The experiments are designed to obtain in-situ measurements of E- and F-region AC and DC electric fields, plasma velocity, neutral winds, and plasma densities. The Principal Investigato is Dr. Erhan Kudeki/University of Illinois.
