CAPE CANAVERAL, Fla. – At Astrotech Space Operations in Titusville, Fla., workers check the fittings of the hoist supporting NASA's Solar Dynamics Observatory, or SDO, after its rotation. The SDO will be moved to a work stand. 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. In preparation for its anticipated November launch, engineers will perform a battery of comprehensive tests to ensure SDO can withstand the stresses and vibrations of the launch itself, as well as what it will encounter in the space environment after launch.
