Imagine standing on Mars, and seeing this with your own eyes.
The Perseverance rover watched as the potato-shaped moon Phobos passed in front of the Sun, from the vantage point of Jezero Crater on Mars.Perseverance used its high-resolution Mastcam-Z camera system to shoot video of Phobos, and NASA says the result is the most zoomed-in, highest frame-rate observation of a Phobos solar eclipse ever taken from the Martian surface.
The stunning eclipse took place on 2 April 2022 and the eclipse lasted a little over 40 seconds. That means this video is very close to what Perseverance witnessed in real time. The time it takes for Phobos to eclipse the Sun is much less time than a typical solar eclipse involving Earth's Moon, since Phobos is about 157 times smaller than our own Moon.
The Mastcam-Z has special solar filters that allow it to stare directly at the Sun. The video is of such high resolution, that even sunspots are visible on the Sun. Truly fascinating. I zoomed in with my Mastcam-Z camera on a Phobos solar eclipse. This detailed video can help scientists on my team better understand the Martian moon's orbit and how its gravity affects the interior of Mars, including its crust & mantle.
