When NASA’s Perseverance rover landed on Mars in February 2021, it carried a high-definition video camera, complete with a powerful zoom capability. This camera has since provided all sorts of amazing views of the red planet during the last 14 months.

However, earlier this month operators of rover turned its powerful Mastcam-Z camera toward the sky to capture Mars’ potato-shaped moon Phobos transiting across the surface of the Sun. And the result, well, the result is spectacular.

Phobos is much smaller than Earth’s Moon, measuring only about 20 km across, so it does not plunge Mars into darkness. However, with the moon etched against the Sun, the video reveals the lumpy nature of Phobos’ terrain, complete with ridges and small hills. It also showcases sunspots on the surface of our star.
