SOHO is designed to study the internal structure of the Sun, its extensive outer atmosphere and the origin of the solar wind, the stream of highly ionized gas that blows continuously outward through the Solar System.
SOHO is helping us understand the interactions between the Sun and the Earth's environment better than has been possible to date.

The IMAGE observatory is a spacecraft that measures 2.25 meters (7.4 feet) in diameter and 1.52 meters (4.99 feet) in height and weighs 494 kg (1087 pounds) (including instruments). Viewed from either end, it has the form of a regular octagon. Arrays of high-efficiency, solar cells attached to the spacecraft's eight side and two end panels provide power to the scientific instruments and subsystems, which together require an orbit-averaged power of 250 Watts.
