SECCHI is a suite of 5 scientific telescopes that will observe the solar corona and inner heliosphere from the surface of the Sun to the orbit of Earth. These unique observations will be made in stereo for NASA's Solar Terrestial Relations Observatory STEREO. The suite has three main parts. The SCIP (Sun Centered Imaging Package - three telescopes), the HI (Heliospheric Imager - two telescopes) and the SEB (Secchi Electronics box).

The STEREO mission is the third in the line of Solar-Terrestrial Probes (STP) and is a strategic element of the Sun-Earth Connections Roadmap. STEREO is designed to view the three-dimensional (3D) and temporally varying heliosphere by means of an unprecedented combination of imaging and in situ experiments mounted on virtually identical spacecraft flanking the Earth in its orbit.

The primary goal of the STEREO mission is to advance the understanding of the three-dimensional structure of the Sun's corona, especially regarding the origin of coronal mass ejections (CMEs), their evolution in the interplanetary medium, and the dynamic coupling between CMEs and the Earth environment. CMEs are the most energetic eruptions on the Sun, are the primary cause of major geomagnetic storms, and are believed to be responsible for the largest solar energetic particle events.
