Original Caption Released with Image	NASA's Solar TErrestrial RElations Observatory (STEREO) satellites have provided the first three-dimensional images of the Sun. For the first time, scientists will be able to see structures in the Sun's atmosphere in three dimensions. The new view will greatly aid scientists' ability to understand solar physics and thereby improve space weather forecasting. This image is a composite of left and right eye color image pairs taken by the SECCHI Extreme UltraViolet Imager (EUVI) mounted on the STEREO-B and STEREO-A spacecraft. STEREO-B is located behind the Earth, and follows the Earth in orbit around the Sun, This location enables us to view the Sun from the position of a virtual left eye in space. STEREO-A is located ahead of the Earth, and leads the Earth in orbit around the Sun, This location enables us to view the Sun from the position of a virtual right eye in space. The structure of the corona shows well in this image. The EUVI imager is sensitive to wavelengths of light in the extreme ultraviolet portion of the spectrum. EUVI bands at wavelengths of 304, 171 and 195 Angstroms have been mapped to the red blue and green visible portion of the spectrum, and processed to emphasize the three-dimensional structure of the solar material. STEREO, a two-year mission, launched October 2006, will provide 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 -- will trace the flow of energy and matter from the Sun to Earth. They will reveal 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 will become 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 is the third mission in NASA's Solar Terrestrial Probes program within NASA's Science Mission Directorate, Washington. The Goddard Science and Exploration Directorate manages the mission, instruments, and science center. The Johns Hopkins University Applied Physics Laboratory, Laurel, Md., designed and built the spacecraft and is responsible for mission operations. The imaging and particle detecting instruments were designed and built by scientific institutions in the U.S., UK, France, Germany, Belgium, Netherlands, and Switzerland. JPL is a division of the California Institute of Technology in Pasadena.

KENNEDY SPACE CENTER, FLA. - Dwayne Light (left), director of Florida Operations, Astrotech, and Jim Adams, deputy project manager for NASA's Solar Terrestrial Relations Observatory (STEREO), Goddard Space Flight Center, ceremonially open the doors of the new class 10,000 clean-room enclosure at Astrotech, signaling the enclosure is ready for operation. Astrotech is a payload processing facility in Titusville, near Kennedy Space Center. This clean-room enclosure, within the high bay at Astrotech, meets the additional stringent cleanliness requirements necessary for processing STEREO for launch. The enclosure was designed and constructed by Astrotech to meet the spacecraft requirements provided by STEREO project management at NASA's Goddard Space Flight Center, Greenbelt, Md. STEREO consists of two spacecraft whose mission is the first to take measurements of the sun and solar wind in 3-D.

Description	KENNEDY SPACE CENTER, FLA. - Dwayne Light (left), director of Florida Operations, Astrotech, and Jim Adams, deputy project manager for NASA's Solar Terrestrial Relations Observatory (STEREO), Goddard Space Flight Center, ceremonially open the doors of the new class 10,000 clean-room enclosure at Astrotech, signaling the enclosure is ready for operation. Astrotech is a payload processing facility in Titusville, near Kennedy Space Center. This clean-room enclosure, within the high bay at Astrotech, meets the additional stringent cleanliness requirements necessary for processing STEREO for launch. The enclosure was designed and constructed by Astrotech to meet the spacecraft requirements provided by STEREO project management at NASA's Goddard Space Flight Center, Greenbelt, Md. STEREO consists of two spacecraft whose mission is the first to take measurements of the sun and solar wind in 3-D.

KENNEDY SPACE CENTER, FLA. - At Astrotech Space Operations in Titusville, Fla., the transporter carrying the STEREO spacecraft is attached to the truck for transportation to Launch Pad 17-B on Cape Canaveral Air Force Station. At the pad the spacecraft will be lifted into the mobile service tower. STEREO stands for Solar Terrestrial Relations Observatory and comprises two spacecraft. The STEREO mission is the first to take measurements of the sun and solar wind in 3-dimension. This new view will improve our understanding of space weather and its impact on the Earth. The STEREO mission is managed by Goddard Space Flight Center. The Applied Physics Laboratory designed and built the spacecraft. The laboratory will maintain command and control of the observatories throughout the mission, while NASA tracks and receives the data, determines the orbit of the satellites, and coordinates the science results.

KENNEDY SPACE CENTER, FLA. - Inside the mobile service tower on Launch Pad 17-B at Cape Canaveral Air Force Station, one segment of the fairing is lifted toward the STEREO spacecraft in the foreground. The fairing is a molded structure that fits flush with the outside surface of the Delta II upper stage booster and forms an aerodynamically smooth nose cone, protecting the spacecraft during launch and ascent. The STEREO (Solar Terrestrial Relations Observatory) mission is the first to take measurements of the sun and solar wind in 3-dimension. This new view will improve our understanding of space weather and its impact on the Earth. Designed and built by the Applied Physics Laboratory (APL) , the STEREO mission is being managed by NASA Goddard Space Flight Center. APL will maintain command and control of the observatories throughout the mission, while NASA tracks and receives the data, determines the orbit of the satellites, and coordinates the science results.

KENNEDY SPACE CENTER, FLA. - The Delta II rocket carrying the STEREO spacecraft on top streaks through the smoke as it climbs to orbit. Liftoff from Launch Pad 17-B at Cape Canaveral Air Force Station was at 8:52 p.m. EDT. STEREO (Solar Terrestrial Relations Observatory) is a two-year mission using two nearly identical observatories, one ahead of Earth in its orbit and the other trailing behind. The duo will provide 3-D measurements of the sun and its flow of energy, enabling scientists to study the nature of coronal mass ejections and why they happen. The ejections are a major source of the magnetic disruptions on Earth and are a key component of space weather. The disruptions can greatly effect satellite operations, communications, power systems, humans in space and global climate. Designed and built by the Johns Hopkins University Applied Physics Laboratory (APL) , the STEREO mission is being managed by NASA Goddard Space Flight Center. APL will maintain command and control of the observatories throughout the mission, while NASA tracks and receives the data, determines the orbit of the satellites, and coordinates the science results.
