Explanation

DISCOVR orbits the sun inside Earth’s own solar orbit and outside the moon’s Earth orbit. Looking away from the sun, at the time when moon and Earth are properly aligned, DISCOVR can see the moon’s backside as the moon orbits our planet.

The same backside perspective would hold true, if DISCOVER were outside the Earth’s orbit, looking sunward at the moon as the moon zips around the Earth.

The moral? — Providing a sense of place

Cool stuff, don’t you think?
