A newer version of this visualization is available.
The 2012 Earth-Orbiting Heliophysics Fleet
Revision (November 9, 2012): The RBSP mission has been renamed the Van Allen Probes. NASA Press Release.
The satellite orbits are color coded for their observing program:
Magenta: TIM (Thermosphere, Ionosphere, Mesosphere) observations Yellow: solar observations and imagery Cyan: Geospace and magnetosphere Violet: Heliospheric observations
- Hinode: Observes the Sun in multiple wavelengths up to x-rays. SVS page
- RHESSI : Observes the Sun in x-rays and gamma-rays. SVS page
- TIMED: Studies the upper layers (40-110 miles up) of the Earth's atmosphere.
- FAST: Measures particles and fields in regions where aurora form.
- CINDI: Measures interactions of neutral and charged particles in the ionosphere.
- SORCE: Monitors solar intensity across a broad range of the electromagnetic spectrum.
- AIM: Images and measures noctilucent clouds. SVS page
- RBSP: (Renamed the Van Allen Probes) Designed to study the impact of space weather on Earth's radiation belts. SVS page
- SDO: Solar Dynamics Observatory keeps the Sun under continuous observation at 16 megapixel resolution.
- GOES: The newest GOES satellites include a solar X-ray imager operated by NOAA.
- Geotail: Conducts measurements of electrons and ions in the Earth's magnetotail.
- Cluster: This is a group of four satellites which fly in formation to measure how particles and fields in the magnetosphere vary in space and time. SVS page
- THEMIS: This is a fleet of three satellites to study how magnetospheric instabilities produce substorms. Two of the original five satellites were moved into lunar orbit to become ARTEMIS. SVS page
- IBEX: The Interstellar Boundary Explorer measures the flux of neutral atoms from the heliopause.
Lunar Orbiting Fleet
- ARTEMIS: Two of the THEMIS satellites were moved into lunar orbit to study the interaction of the Earth's magnetosphere with the Moon.
Note: A number of near-Earth missions had their orbits generated from Two-Line orbital elements valid in July 2012. Orbit perturbations since then may result in significant deviation from the actual satellite position for the time frame of this visualization.
