THEMIS Orbits: Dayside Science Configuration
In the early part of the mission, the five THEMIS satellites will follow the same orbit single-file. The apogee of the orbit will take the spacecraft just beyond the bow shock of the Earth's magnetosphere. This will enable the satellites to collect data in this region over a short range of time so that the time history can be studied. The dates in this visualization are based on an ephemeris assuming a launch on January 20, 2007. The satellite colors are: red=P1, green=P2, cyan=P3, blue=P4, magenta=P5.

This movie looks down onto the north pole of the Earth and the five THEMIS spacecraft travelling along a single elliptical orbit. The Sun is to the left.    This movie looks down onto the north pole of the Earth and the five THEMIS spacecraft travelling along a single elliptical orbit. The Sun is to the left.

This is an opening shot of the animation. Satellites P1 (red) and P4 (blue) are too close together to be distinguished as separate objects on this scale.    This is an opening shot of the animation.

The satellites swing through their perigee, moving more swiftly close to the Earth. You can now distinguish satellites P1 (red) and P4 (blue).    The satellites swing through their perigee, moving more swiftly close to the Earth. You can now distinguish satellites P1 (red) and P4 (blue).
