STEREO

STEREO (Solar TErrestrial RElations Observatory) is the third mission in NASA's Solar Terrestrial Probes program (STP). The mission, launched in October 2006, has provided a unique and revolutionary view of the Sun-Earth System. The two nearly identical observatories - one ahead of Earth in its orbit, the other trailing behind - have traced the flow of energy and matter from the Sun to Earth. STEREO has revealed the 3D structure of coronal mass ejections; violent eruptions of matter from the sun that can disrupt satellites and power grids, and help us understand why they happen. STEREO is a key addition to the fleet of space weather detection satellites by providing more accurate alerts for the arrival time of Earth-directed solar ejections with its unique side-viewing perspective.

STEREO Data

  • STEREO in stereo: Spring 2007 at 171 Ångstroms

    With the 10th Anniversary of the launch of the STEREO mission, two spacecraft orbiting the Sun to study space weather from multiple vantage points, it seemed a good time to revisit some older STEREO visualizations and update them to the newer display technologies. For each movie, we have combined 1K and 2K images from the STEREO spacecraft to maximize the continuity. The images between left and right eye have a 10 arcsecond offset from the image center. This has worked well in our stereo experiments for a variety of display sizes from 18 to 80 inches. Note on making color stereo movies: Left and Right eye frame sequenences under this animation are available for those who have the technology and want to encode color stereo movies for the variety of display technologies available. A word of caution. In generating these products, there was the goal of making a complete stereo product but also provide as complete a data run for each spacecraft. Many frames for one eye do not necessarily have a matching stereo frame for the other. If there are matching frame numbers between the left and right eye, they should make the appropriate stereo pair, but this screening was done manually and errors may exist. Please notify us if you encounter them.

    NASA Solar Probes Celebrate 10 Years of Uncovering Mysteries of Space Weather

    STEREO Mission Gave First Ever 360-Degree Views of Our Star, Origin of Solar Wind

    Ten years ago on Oct. 25, 2006, NASA launched twin satellites into orbit to get the first 360-degree view of the sun at one time. The Solar-Terrestrial Relations Observatories (STEREO) spacecraft have helped NASA scientists to better understand how the sun affects Earth and the solar system, including the harsh space environment that spacecraft – or even astronauts – may experience in space.

    Join NASA scientists on Friday, Oct. 21, from 6:00 a.m. to 11:30 a.m. EDT to show your viewers revolutionary solar images from this mission that has uncovered some of the mysteries surrounding the origin of space weather.

    With STEREO-A ahead of Earth in its orbit and STEREO-B trailing behind, the observatories have captured 3D views of the sun’s regular violent eruptions of matter, which trigger the aurora and can – at their worst – disrupt satellites and even cause electrical power outages. STEREO has served as a key addition to a fleet of space weather detection satellites by providing unique data to better help us understand what sets off such solar eruptions and how they travel toward Earth.
