description STEREO-B Overview

STEREO-B, also called STEREO Behind, is one of two nearly identical NASA spacecraft launched in 2006 to observe the Sun from separated positions in heliocentric orbit. Together with STEREO-A, it enabled three-dimensional studies of solar eruptions and the space weather they generate. Contact was lost in 2014, briefly recovered in August 2016, and lost again shortly afterward despite subsequent recovery attempts.

help STEREO-B FAQ

What was STEREO-B designed to study?

STEREO-B was designed to observe the Sun and solar eruptions from a separated position in heliocentric orbit. Working with STEREO-A, it helped scientists study space weather in three dimensions.

What does STEREO-B stand for?

STEREO-B is also called STEREO Behind. The name refers to its position relative to Earth's orbit around the Sun.

When was STEREO-B launched?

STEREO-B was launched in 2006 as one of two nearly identical NASA spacecraft. The other spacecraft was STEREO-A.

How did STEREO-B work with STEREO-A?

The two spacecraft viewed the Sun from different locations in heliocentric orbit. Their separated observations allowed researchers to reconstruct three-dimensional views of solar eruptions.
