The Planetary Society' Space Missions
The Planetary Society’s vision is to know the cosmos and our place within it. We follow the world’s space exploration missions and produce news and resources you won’t find anywhere else.
The science of the Solar Dynamics Observatory will be performed on a spacecraft that allows both nearly continuous observations of the Sun and a science data downlink rate over of 100 Megabits per second (Mbps). These two requirements determined the orbit and spacecraft design as well as the definition of the SDO Mission.
