Sounding Rocket Launches Into Aurora Over Venetie,
Alaska
On March 3, 2014, at 6:09 a.m. EST, a NASA-funded sounding rocket launched
straight into an aurora over Venetie, Alaska. The Ground-to-Rocket
Electrodynamics – Electron Correlative Experiment (GREECE) sounding rocket
mission, which launched from Poker Flat Research Range in Poker Flat, Alaska,
will study classic curls in the aurora in the night sky.
The GREECE mission seeks to understand what combination of events sets up
these auroral curls as they're called, in the charged, heated gas – or plasma –
where aurorae form. This is a piece of information, which in turn, helps paint a
picture of the sun-Earth connection and how energy and particles from the sun
interact with Earth's own magnetic system, the magnetosphere.
