The moon passed between Nasa’s Deep Space Climate Observatory and the Earth allowing this rare pic
Deep Space Climate Observatory (DSCOVR; formerly known as Triana, unofficially known as GoreSat is a National Oceanic and Atmospheric Administration (NOAA) space weather, space climate, and Earth observation satellite. It was launched by SpaceX on a Falcon 9 v1.1 launch vehicle on 11 February 2015, from Cape Canaveral. This is NOAA’s first operational deep space satellite and became its primary system of warning Earth in the event of solar magnetic storms.
On 6 July 2015, DSCOVR returned its first publicly released view of the entire sunlit side of Earth from 1,475,207 km (916,651 mi) away, taken by the EPIC instrument. The moon is roughly 250,000 miles from earth. EPIC provides a daily series of Earth images, enabling the first-time study of daily variations over the entire globe. The images, available 12 to 36 hours after they are made, have been posted to a dedicated web page since September 2015.
