Cluster →
The Cluster mission is an in-situ investigation of the Earth's magnetosphere using four identical spacecraft simultaneously.
-
ACE - Advanced Composition Explorer →
ACE's mission observes particles of solar, interplanetary, interstellar, and galactic origins, spanning the energy range from solar wind ions to galactic cosmic ray nuclei.
-
Geotail →
The Geotail mission's primary objective is to study the dynamics of the Earth's magnetotail over a wide range of distance, extending from the near-Earth region to the distant tail.

SoHO - Solar and Heliospheric Observatory
SoHO's mission is to study the Sun, from its deep core to the outer corona, and the solar wind.
-
SDO - Solar Dynamics Observatory
Solar Dynamics Observatory's (SDO) mission is to understand the Sun's influence on Earth and Near-Earth space by observing the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.
-
IBEX - Interstellar Boundary Explorer
IBEX is the first mission designed to detect the edge of the Solar System.
-
STEREO - Solar Terrestrial Relations Observatory
The STEREO mission employs two nearly identical space-based observatories - one ahead of Earth in its orbit, the other trailing behind - to provide the first-ever stereoscopic measurements to study the Sun and the nature of its coronal mass ejections (CMEs).
-
THEMIS - Time History of Events and Macroscale Interactions during Substorms
THEMIS answers longstanding fundamental questions concerning the nature of the substorm instabilities that abruptly and explosively release solar wind energy stored within the Earth’s magnetotail.

AIM - Aeronomy of Ice in the Mesosphere
Fifty miles above the ground, Earth's highest clouds form an icy membrane at the edge of the atmosphere. AIM's mission is to study these mysterious Polar Mesospheric Clouds.
-
Hinode (Solar-B)
Hinode is exploring the magnetic fields of the Sun and is improving our understanding of the mechanisms that power the solar atmosphere and drive solar eruptions.
