Stepping Stones to SDO
NASA's Solar Dynamics Observatory (SDO) is currently in the 'integration and test' phase of mission development, (i.e. observatory is now complete with the spacecraft bus, propulsion module and instruments), the ground system is being completed and flight software is being tested. Critical systems testing has already begun and environmental testing of he observatory will be conducted in the near future as they continue towards a launch readiness date of December 1, 2008. This series of short videos shows the SDO spacecraft being assembled and tested with narration by the engineers doing the work. It will be updated until SDO is ready for launch.

For more information on SDO, visit the web site http://sdo.gsfc.nasa.gov


<b>SDO OFFICIALLY AN OBSERVATORY</b><br /> A major milestone was reached when Goddard engineers recently attached the instrument module to the spacecraft bus transforming it officially into an observatory. With its three instruments (AIA, EVE, and HMI), SDO will deliver startling images of the Sun that are ten times better than HD! <p>For complete transcription of this video, please click <a href='officially_observatory.html'>here</a>.    SDO OFFICIALLY AN OBSERVATORY

<b>PROPULSION AND BUS INTEGRATION</b> <br />After launch, SDO's propulsion system will boost the spacecraft into its geosynchronous orbit. Thrusters using the same fuel and oxidizer mix will keep SDO in the correct orbit during the mission.
