**LIVE UPDATE PAGES**<\/font><\/em><\/p>\n **DELTA II LAUNCH VIDEO \u2013 From T-4 mins to Spacecraft Seperation and multi-view launch replays**<\/font><\/em> \u2013 <\/p>\n <\/em> \u2018STEREO is another exciting mission for NASA to help them gain a better understanding of our universe,\u2019 said Dan Collins, vice president and general manager, Boeing Launch Systems. <\/p>\n \u2018Our Delta team takes tremendous pride in our work, and we are extremely pleased to help NASA reach its goals.\u2019<\/p>\n <\/font><\/font><\/font><\/p>\n <\/p>\n Mission Preview<\/em><\/p>\n <\/u>The STEREO launch will mark the third mission in NASA\u2019s Solar Terrestrial Probes (STP) program, on a two year mission to observe the sun, dramatically improving the understanding of the powerful solar eruptions that can send more than a billion tons of the sun\u2019s outer atmosphere hurtling into space. <\/p>\n The STEREO mission comprises two nearly identical spacecraft the size of golf carts. Their observations will enable scientists to construct the first-ever three-dimensional views of the sun. These images will show the sun\u2019s stormy environment and its effect on the inner solar system. The data are vital for understanding how the sun creates space weather. <\/p>\n During the two-year mission, the two spacecraft will explore the origin, evolution and interplanetary consequences of coronal mass ejections, some of the most violent explosions in our solar system. When directed at Earth, these billion-ton eruptions can produce spectacular aurora and disrupt satellites, radio communications and power systems. Energetic particles associated with these solar eruptions permeate the entire solar system and may be hazardous to spacecraft and astronauts. <\/p>\n \u2018In terms of space-weather forecasting, we\u2019re where weather forecasters were in the 1950s,\u2019 said Michael Kaiser, STEREO project scientist at NASA\u2019s Goddard Space Flight Center. \u2018They didn\u2019t see hurricanes until the rain clouds were right above them. In our case, we can see storms leaving the sun, but we have to make guesses and use models to figure out if and when they will impact Earth.\u2019 <\/p>\n The mission will employ two nearly identical space-based observatories \u2013 one ahead of Earth in its orbit, the other trailing behind \u2013 to provide the first-ever stereoscopic measurements to study the Sun and the nature of its coronal mass ejections, or CMEs.<\/p>\n The two solar-powered observatories with 3-axis-stabilization, will each have a launch mass (including propellant) of approximately 1,364 pounds (620 kilograms). The spacecraft will communicate with the APL-based (The Johns Hopkins University Applied Physics Laboratory) Mission Operations Center via NASA\u00e2\u20ac\u2122s Deep Space Network.<\/p>\n Each STEREO observatory has 16 instruments. The observatories have imaging telescopes and equipment to measure solar wind particles and to perform radio astronomy. <\/p>\n <\/font><\/font><\/font><\/p>\n \u2018STEREO is charting new territory for science research and the building of spacecraft. The simultaneous assembly, integration and launch of nearly identical observatories have been an extraordinary challenge,\u2019 said Nick Chrissotimos, STEREO project manager a Goddard.<\/p>\n Onboard instruments for STEREO include:<\/u><\/em> <\/p>\n Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) will have four instruments: an extreme ultraviolet imager, two white-light coronagraphs and a heliospheric imager. These instruments will study the 3-D evolution of CME\u2019s from birth at the Sun\u2019s surface through the corona and interplanetary medium to its eventual impact at Earth.<\/p>\n STEREO\/WAVES (SWAVES) is an interplanetary radio burst tracker that will trace the generation and evolution of traveling radio disturbances from the Sun to the orbit of Earth.<\/p>\n In-situ Measurements of Particles and CME Transients (IMPACT) will sample the 3-D distribution and provide plasma characteristics of solar energetic particles and the local vector magnetic field.<\/p>\n PLAsma and SupraThermal Ion Composition (PLASTIC) will provide plasma characteristics of protons, alpha particles and heavy ions. This experiment will provide key diagnostic measurements of the form of mass and charge state composition of heavy ions and characterize the CME plasma from ambient coronal plasma. **INFINITY: 10 minute STS-115 MUSIC VIDEO**<\/font><\/em> \u2013 **NASASpaceflight.com Job Opportunities**<\/em><\/font> <\/p>\n <\/font> A Boeing Delta II (7925-10L) launch vehicle has launched, carrying the STEREO (Solar TErrestrial RElations Observatory) into orbit for NASA. Launch was at 8:52pm EDT from Cape Canaveral Air Force Station in Florida. The launch was slightly delayed to the end of the 15 minute launch window due to a constraint on the range.
