AB: The Atmospheric Imaging Assembly (AIA) is one of three science investigations selected for the NASA Solar Dynamics Observatory, the first mission in NASA's Living With a Star program that is designed to study the Sun's influence on the Earth and the nearby environment. AIA consists of four normal incidence telescopes with multilayer coated optics. It records solar EUV emission with high spatial resolution (0.6 arcsec pixels) at six wavelengths from iron ions in the solar atmosphere at temperatures between 6.3 × 10⁵ K and 15 × 10⁶ K: Fe IX (171Å); Fe XII,XXIV (193Å); Fe XIV (211 Å); Fe XVI (335Å); Fe XVIII (94Å); and Fe XX,XXIII (131Å). Other wavelength channels enable observations of the chromosphere (He II, 304Å; C IV) and the photosphere. Each telescope contains a 16-Mpixel CCD/camera system and has a 41 arcmin field of view. AIA will return 8 full solar-disk images every 10 s, producing 2.2 Tbytes/day of data. The AIA investigation is led by PI Alan Title (LMSAL) with major participation by the Harvard Smithsonian Astrophysical Observatory, Montana State University, and Stanford University. The SDO mission is scheduled for launch in 2008 and will have a nominal five year mission lifetime, but will carry resources for at least ten years of mission operations.
