Mission Information

SDO L-1 Briefing
02.09.10
 
The Solar Dynamics Observatory, or SDO, is set to launch on Wednesday, Feb. 10, at 10:26 a.m. EST from Launch Complex 41 at Cape Canaveral Air Force Station in Florida. The Launch Readiness Review was conducted Monday morning and the "go" was given to proceed, with no technical issues reported.

A prelaunch news conference will be held at 1 p.m. on Tuesday, followed by the mission science briefing. Both will be carried live on NASA TV. Live coverage of the launch will begin at 7:15 a.m. Wednesday on NASA TV and the launch blog.

SDO's unprecedented mission will study the sun and its dynamic behavior. Onboard telescopes will scrutinize sunspots and solar flares using more pixels and colors than any other observatory in the history of solar physics. And SDO will reveal the sun’s hidden secrets in a prodigious rush of pictures.
