The Rocket
THEMIS was thundered into orbit aboard a Delta II rocket. The Delta II is designed to boost medium-sized satellites and robotic explorers into space. NASA selected a model 7925-10 for this mission, which is a three-stage rocket equipped with nine strap-on motors and a protective 10-foot payload fairing.

NASA Launch Vehicles
NASA has several rockets for launching various types of science missions. The image below provides a side-by-side comparison.

The Mission
THEMIS is a mission to investigate what causes auroras in the Earth's atmosphere to dramatically change from slowly shimmering waves of light to wildly shifting streaks of color. The process that triggers substorms occurs deep within the Earth's magnetosphere, the region of space surrounding the Earth that is dominated by the Earth's magnetic field. At substorm orbit, stretched magnetic field lines snap back to a configuration similar to that of a bar magnet, energizing charged particles and dumping them into the Earth's upper atmosphere, where they produce shimmering aurora that can be seen at high latitudes in both the northern and southern hemisphere. Discovering what causes auroras to change will provide scientists with important details on how the magnetosphere works and the important Sun-Earth connection.
