CAPE CANAVERAL, Fla. – At the Astrotech Space Operations facility in Titusville, Fla., the Solar Dynamics Observatory, or SDO, is vertically positioned during preparations for propulsion system testing and leak checks. SDO is the first space weather research network mission in NASA's Living With a Star Program. The spacecraft's long-term measurements will give solar scientists in-depth information about changes in the sun's magnetic field and insight into how they affect Earth.
