Heliophysics Sentinels 2020 (Forecast Version)
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
- TIMED: Studies the upper layers (40-110 miles up) of Earth's atmosphere. SVS page
- ICON: Works with GOLD on studies of the ionosphere.
- AIM: Images and measures noctilucent clouds. SVS page
- IRIS: Interface Region Imaging Spectrograph is designed to take high-resolution spectra and images of the region between the solar photosphere and solar atmosphere. SVS page
- SET: Space Environment Testbed exploring radiation-hardening technologies
- GOES East & GOES West: The GOES satellites provide continuous imagery of Earth's western hemisphere and monitor the solar X-ray flux.
- SDO: Solar Dynamics Observatory keeps the Sun under continuous observation at 16 megapixel resolution. SVS page
- GOLD: Global-scale Observations of the Limb and Disk is a spectroscopic imager for studying the ionosphere.
- Geotail: Conducts measurements of electrons and ions in the Earth's magnetotail. SVS page
- Magnetospheric Multi-scale (MMS): 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 THEMIS-ARTEMIS. SVS page
- IBEX: The Interstellar Boundary Explorer measures the flux of neutral atoms from the heliopause. SVS page
Lunar Orbiting Fleet:
- THEMIS-ARTEMIS: Two of the THEMIS satellites were moved into lunar orbit to study the interaction of the Earth's magnetosphere with the Moon. SVS page
Sun-Earth Lagrange Point One Fleet:The L1 point is a Lagrange Point between the Sun and the Earth. Spacecraft can orbit this location for continuous coverage of the Sun.
- DSCOVR: Observes Earth and measures the solar wind.
- SOHO: Studies the Sun with cameras and a multitude of other instruments. SVS page
- ACE: Measures the composition and characteristics of the solar wind. SVS page
- Wind: Measures particle flows and fields in the solar wind. SVS page
