Interesting how the three separate R/G/B images are taken independently a few ~seconds~ milliseconds apart, with a different color filter placed over the image sensor.
I assume this is to maximize resolution, since no Bayer interpolation [0] is needed to demosaic the output of a traditional image sensor that integrates the color filters onto the sensor pixels themselves. As these satellites are not intended to photograph things in motion, the color channel alignment artifacts seen here are a rare, small price to pay for vastly improved resolution and absence of demosaicing artifacts.
