Yeah. Um… Wow. Nice Job NASA. I’ll just copy/paste how The Planetary Society explained it:
“NASA's Curiosity team made this artistic interpretation of the rover's view from high up Mt. Sharp by combining pictures taken at different times of day and adding colors to bring out the contrast. The first set of images was taken at 8:30 a.m local Mars time on Nov. 16, and the second set at 4:10 p.m. The morning light is highlighted in blue, while the afternoon is orange.”
