Milestones

The SDO observatory was launched on February 11, 2010, 10:23 am EST. SDO is now in the "Launch and Early Operations" phase of mission development, during which the instruments and spacecraft are turned on and tested on orbit. At the same time, ground system is used to control the spacecraft and accept the data from the instruments and subsystems. Once the spacecraft and instruments are commissioned SDO will begin its observing of the Sun. This prime observing phase of SDO is planned to last five years - almost half a solar cycle - with the possibility of a 5-year extension.
