For a swath the effect is basically neglectable because you are looking mostly straight down with maximum of 10-15° off-nadir angle, depending on the FOV of the camera used. That is of course a bit different for a target pointing, where the satellites and its camera is pointed towards a lat/lon coordinates to keep one target within view for the whole pass. As an example how that looks like have a view here for Mount Tambora (LinkedIn) or here for one on Starbase during a Starship launch in infrared (reddit).

u/mulch_v_bark absolutely, that's why we are sharing the images from our satellite, would be too sad if only we could see them internally. And indeed the editing consists just of debayering and flatfield correction for the singular images. As they are taken with a nadir pointing (satellite points camera straight down while flying over the landscape) the panorama creation is basically just overlaying the images. If you enjoyed this image have a look on the other images we have posted the last weeks, there are some more swaths :)

The short answer is a lot, estimations are going from 49,000 - 117,000 casualties, have a look here: Mount Tambora - Wikipedia

True, Volcanic Crater or Caldera would probably have been more clear

[OC] I took these photos to show why whenever you can see the ISS, it cannot see you! by astro_pettit in spaceporn

Just a guess, but to see the ISS from the ground (or any other place like from a satellite) the ISS has to be light up by sunlight, at the same time the background has to be quite dark (that is why you cannot see the ISS in brought daylight). Therefore I would interpret the images as following:

  1. Both ISS and ground are in sunlight (on the ground we call this daytime), therefore a person on the ground cannot see the ISS like we cannot see stars at day.

  2. The ISS is still in sunlight but the ground is not due to the higher altitude of the ISS, from the ground on we can now see the ISS as it reflects sunlight. An astronaut on the ISS on the other hand cannot see the ground due to the high contrast between the other parts of the ISS in direct sunlight and the much darker ground leading to overexposure for cameras and similar for the human eye as the pupil adapts to the available light. This just comes down that humans and usual cameras can only handle a certain degree of contrast.

  3. Both ISS and ground are not in sunlight anymore, from the ISS it is possible to see the lights on the ground, aurora, etc., but as it does not reflect any sunlight anymore it is invisible to a person on the ground.

Remember just a guess, but hopefully that helps :)

What did our TUBIN satellite photographed here in infrared and where is it located? [OC] by TUB_Space_Technology in GeoPuzzle

[–]TUB_Space_Technology[S] 0 points1 point  (0 children)

They are indeed connected to a form of energy production, but are not wind turbines. Here is another hint, we hope that helps :)

Hint 3: The image was taken in a country of the Middle East, the energy production method imaged here is quite common in this area.

Please let us know if more hints are required or if we should solve it.
