If you've never heard of it, this bird always stays on the sunlit side of the planet and takes true color images

It takes actual full disk images too! None of this stitching shenanigance without the edge effects that all the geo orbit satelites do.

Goes-17 sees at best 2x2 km boxes (igfov depends on wavelength) and uses mirrors on servos to quickly scan the disk. DSCOVR is simply far enought away that it can see the full disk.

If you need reference materials for how earth like planets look from space, use DSCOVR images, everything else is fake!
