This particular eclipse took place on April 2, the 397th Martian day of the mission, and only lasted 40 seconds which is significantly less time than a typical solar eclipse of Earth’s moon takes. “Studying how much Phobos shifts over time reveals something about how resistant the crust and mantle are, and thus what kinds of materials they’re made of.”
“The moon’s tidal forces pull on the deep interior of the Red Planet, as well as its crust and mantle,” NASA’s Jet Propulsion Laboratory (JPL) explains. NASA explains that observations like this help them measure the subtle shifts in Phobos’s orbit over time. And it’s cool that you can see this eclipse exactly as the rover saw it from Mars,” says Mark Lemmon, a planetary astronomer with the Space Science Institute in Boulder, Colorado, who has orchestrated most of the Phobos observations by Mars rovers. It is presented in color by combining data from the camera’s blue-green, red, and near-infrared channels. This is the first, taken from a distance of about 6,800 kilometers (about 4,200 miles). The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter took two images of the larger of Mars’ two moons, Phobos, within 10 minutes of each other on March 23, 2008.
NASA explains that the Mastcam-Z has a solar filter that reduces light intensity, allowing scientists to see the details in the shape of Phobos’s shadow such as ridges and bumps in the landscape. Perseverance’s camera also brings another element that makes its footage special: color.
