SDO | Solar Dynamics Observatory - Milestones
MILESTONES
SDO is currently in the "design and build" phase of mission development, i.e. the instruments and spacecraft are being built, the ground system is being developed, and the flight software is being written. Tests of critical systems have already begun, in preparation for the full spacecraft assembly, system tests and verification, culminating in an December 2008 launch. The prime observing phase of SDO is planned for five years - half a solar cycle - with the possibility of a 5-year extension.
