ORIGINAL CAPTION: This view of the twilight sky and Martian horizon, taken by NASA's Mars rover Curiosity, includes Earth as the brightest point of light in the night sky.
Earth is a little left of center in the image, and our moon is just below Earth. A human observer with normal vision, if standing on Mars, could easily see Earth and the moon as two distinct, bright "evening stars."
