The images are almost ALWAYS b&w. They record the amount of light and not the color. Colour images actually waste cpu cycles and bandwidth and can ultimately be less accurate, so they take photos of light spectrum only. They take a red, a green and a blue spectrum photo, then filter and assemble back on earth later. Usually why photos in color take time to surface.
- aren't objects with no atmosphere grey monochrome? The mars pics have color.hotroddy

- They do capture lots of color images. They record the amount and type of light, allowing the filters beyond what we can perceivemonospaced
- Thanks mono for repeating what my post already states.ETM
- Maybe READ what a post says before commenting.ETM
- you said it was b&w, but that's not actually true... I read what you wrote and not trying to be densemonospaced
- you wrote "almost ALWAYS b&w"monospaced
- Did you read the LAST SENTENCE OF THE POST?ETM
- You understand those spectrum images are b&w, representing the density of light. Almost like an alpha.ETM
- a red spectrum photo is not actually red, blue is not blue. Not until processed on Earth.ETM
