A lot of the images look photoshopped to me - adding flowers to fields, tractors, and the lights in the windows you mentioned.
Of course I say that while thinking that most of the Mars rover photos also look photoshopped, adding sand dunes and rocks without explanation. I’ve been watching the red sky on Mars photos slowly turn blue over the decades - I guess they are trying to come clean before another nation puts a lander there and reveals NASA had been coloring the sky incorrectly.
Maybe China will land a rover and show us what Mars really looks like just to spite the US?
- Kye 6y agoPhotos from Mars are all composites of red, green, and blue images. The way they put the colors together back on Earth depends on the purpose of the image. They might have learned a little from SpaceX on PR and started biasing published images of the Martian sky toward blue. Using three separate filters that are each one different wavelength lets them capture more information than something like a Bayer filter where all three colors share the same space at the same time. Mars doesn't change fast enough to make three separate exposures a problem.

They knew the true colors of Mars in the 70s. I’ve heard that they colored the sky and rocks red because they thought the public expected red and maybe that’s the reason, but they’ve been transitioning it to an increasingly blue sky and grey rocks ever since.
