What an interesting design for a lawnmower. Joking aside, better make a screenshot because this is liable to be blurred soon.
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 photog…
My napkin calculations are that the three channels are ~10ms apart, given the bomber is 69 feet nose-to-tail* and an assumption of 400 mph velocity. * http://www.dept.aoe.vt.edu/~mason/Mason_f/B2Spr09.pdf

All the B-2s are based at nearby Whiteman Air Force Base. They fly over often -- one even fly over my farm today about an hour ago.
This one was probably on final approach during the summer when the winds are usually out of the south and was probably about 2,000 feet above the ground.

I wonder if there are ways to get superior (compared to Bayer) color images from conventional raw-capable monochrome digital cameras (like Leica Q2 Monochrom) in static scenes using similar workflows of taking three separate shots.
In fact, the first color photos in the world were taken this way in the early 1900s [1]: take three monochrome exposures onto black and white transparencies with R/G/B filters, and then project the three images together.

I live on a farm very close to this area. All the B-2s are based at nearby Whiteman Air Force Base. They fly over often -- one even fly over my farm today about an hour ago.

I wonder if imaging from above could actually be a threat for these planes. I mean -- stick cameras on all the SpaceX satellites and you've got an awful lot of eyeballs in LEO, right? Might at least be able to tell a ground based radar where to focus their search...
They fly in the dark and IR imaging doesn't work very well due to coatings and trying to hide the engine heath signature.
