The 2013 Earth-Orbiting Heliophysics Fleet

There is a newer version of this story located here: https://svs.gsfc.nasa.gov/4288
There've been a few changes since the 2012 Earth-Orbiting Heliophysics Fleet. As of Fall of 2013, 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.

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
  • Van Allen Probes: Two probes moving along the same orbit esigned to study the impact of space weather on Earth's radiation belts. SVS page
  • TWINS: Two Wide-Angle Imaging Neutral-Atom Spectrometers (TWINS) are two probes observing the Earth with neutral atom imagers.
  • IRIS: Interface Region Imaging Spectrograph is designed to take high-resolution spectra and images of the region between the solar photosphere and solar atmosphere.

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.
