The perseverance rover has captured images of mars, including a vista that appears clear and a sky that is described as blue in some areas. The color of the sky on mars is affected by the planet's thin air and fine dust, which can scatter sunlight and create a yellow, orange, or blue glow. The rover's images provide a detailed view of the martian terrain, including a region known as 'falbreen', but it is unclear if the blue sky is a typical or unusual occurrence.
