The 2012 Earth-Orbiting Heliophysics Fleet

Since Sentinels of the Heliosphere in 2008, there have been a few new missions, and a few missions have been shut down. As of Fall of 2012, here's a tour of the NASA Near-Earth Heliophysics fleet, covering the space from near-Earth orbit out to the orbit of the Moon.
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


Near-Earth Fleet:

  • 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

Geosynchronous Fleet:

  • 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.

Geospace Fleet:

  • 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.
