So, the Moon orbiting plane is close to the ecliptic, and the satellite is in the ecliptic (L1 is in the ecliptic). I do not get this:
> About twice a year the camera will capture the moon and Earth together as the orbit of DSCOVR crosses the orbital plane of the moon.
(nitpick: the DSCOVR has no "orbit" around the Earth, since it is in the L1 point)
Since the Moon's orbit and the ecliptic are so close, I would expect this crossing to happen more often (on every turn of the Moon around the Earth)
