Let's have a look at a more technical and detailed description: https://an.rsl.wustl.edu/help/Content/About%20the%20mission/MSL/Instruments/MSL%20Navcam.htm The Navcam optics are f-theta fisheye ...

When you specify resolution as a linear size, it becomes dependent on how far away the subject is. Curiosity's cameras take photos at varying distances, so you'd have to have a table with resolutions ...

Perhaps there is an assumption that new photos of Earth taken from space would be inspiring, enlightening, and meaningful in some way. That was certainly true of the first photos that were taken, but ...

Why is there never enough room on satellites to hold all the equipment needed? Welcome to Space Exploration SE! Because of the time involved from planning until completion of goals at the end of the ...

You seem to have overlooked DSCOVR, which pretty much just stares at our planet. https://epic.gsfc.nasa.gov/

We have a large number of sources taking photos of our planet. This includes: low-altitude Earth observation satellites (Landsat, SPOT, Maxar). These take high-resolution photos of a small area at a ...

In fact, there is always enough room on a satellite for everything it needs, because if it couldn't fit something necessary, it wouldn't be able to go into space. (At least, not without failing very ...

Field of view 45 degree doesn't seem a rounding error but just the effect of trigonometry. Simplifying the camera as projecting the image though a point (the center of the lens), knowing the angular ...

I always thought they'd first told Sagan no because they didn't want to spend the fuel to turn it around. They didn't want to point it at the sun. And someone had to ad-hoc some code into it, without ...

Yes, as others have confirmed, milliradians per pixel is angular resolution. Specifically, it's the angle subtended by one pixel at the center of the field of view relative to the center of projection....
