THEMIS/ARTEMIS – 11 Years Post Launch

February 17th is the 11 year anniversary of the launch of the Five THEMIS Spacecraft, a two year mission to study space weather.

THEMIS Overview

NASA’s Time History of Events and Macroscale Interactions during Substorms (THEMIS) aims to resolve one of the oldest mysteries in space physics, namely to determine what physical process in near-Earth space initiates the violent eruptions of the aurora that occur during substorms in the Earth’s magnetosphere.

THEMIS is a 2-year mission consisting of 5 identical probes that will study the violent colorful eruptions of Auroras.
