ACES
Principal Investigator: Scott Bounds
Auroral Current and Electrodynamics Structure (ACES) launched from Poker Flat Research Range on January 29, 2009 to take measurements within a stable auroral arc just north of Fort Yukon, AK. Measurements were also taken using ground radars. ACES consisted of two payloads, a high flyer and a low flyer, launched one minute apart to be magnetically conjugate (on the same magnetic field line) at apogee. Both payloads were instrumented to measure waves, particles, and plasma parameters.
