CAPE CANAVERAL, Fla. – At the Astrotech Space Operations facility in Titusville, Fla., NASA's Solar Dynamics Observatory, or SDO, enclosed in the Atlas V payload fairing, is secured onto a transporter in the airlock in preparation for its move to the pad. SDO is the first mission in NASA's Living With a Star Program and is designed to study the causes of solar variability and its impacts on Earth. The spacecraft's long-term measurements will give solar scientists in-depth information to help characterize the interior of the Sun, the Sun's magnetic field, the hot plasma of the solar corona, and the density of radiation that creates the ionosphere of the planets. The information will be used to create better forecasts of space weather needed to protect the aircraft, satellites and astronauts living and working in space. Liftoff aboard an Atlas V rocket is targeted for Feb. 9 from Launch Complex 41 on Cape Canaveral Air Force Station. For information on SDO, visit http:__www.nasa.gov_sdo.
