Eclipses in Space

High in orbit above the Earth, the Solar Dynamics Observatory watches the Sun year-round, providing stunning stellar views that go unbroken except during a few special times each year. Because the SDO stays relatively fixed over one part of the planet in a geosynchronous orbit, the satellite goes through two annual “eclipse seasons.” For a few weeks twice each year, part of SDO’s view each day will be blocked by the Earth. And, three times a year, the Moon will get in the way.
