The Japanese Hayabusa spacecraft captured a full image of the earth in 2004 during its mission collecting samples from an asteroid. In January 2015, another Japanese craft, the Himawari-8 weather satellite, began recording full-disk images at 10 minute intervals. Even the US’s National Oceanic and Atmospheric Administration GOES satellites capture full-disk images of the earth, but these weather satellites are in geostationary orbits, meaning they capture the same view of the earth over and over.
DSCOVR can capture a full-disk image at any point in the Earth’s rotation.
The images captured during DSCOVR’s mission are an ancillary function for the satellite. Its primary function: to remain between the Earth and the sun to detect solar wind, for scientific and safety purposes. (The safety issue stems from concerns that a geomagnetic storm caused by solar wind could disrupt everything from power grids to the GPS system.) This vantage point gives it a view of an always-fully-lit Earth as the planet spins in front of it. The satellite, launched earlier this year, is expected to take a full earth image at least once a day and transmit it home.
Yes, gravity. Perhaps you can explain something about this. The Nile river travels from lake Victoria in the South to the Mediterranean Sea in the North. Straight distance 2,400 miles (4,130 mi total distance). Lake Victoria surface elevation is 1,133 m (less than a mile). I did a calculation using Earth curvature calculator and the drop, due to Earth curvature, and taking only half of that when assuming the Earth being a ball, is 350 miles. That is more than the distance from Earth to the Space Station. So, on a ball Earth Lake Victoria would have to be above the ISS for water to find its level, and for the Nile river to empty in the Sea.
Is the Nile river subject to gravity in your opinion?
Not trying to discredit you here, because im sure you dont believe sattelites are real..
But one picture has "supposedly" been taken since then.

Just sayin, thats all.
