Phobos from Mars.
(Science Week, day 2!)
Perseverance was the final act of Science Week in 2020, as it launched for Mars. It still elicits double takes to remind ourselves that it's for decades been normal to chat idly about having sent robotic vehicles to Mars. And it's routine enough to hear news about the surface of Mars, where all the action now is, that it's easy to forget that Mars has a moon! And it's surprising enough to remember that Mars has a moon that it's easy to forget that Mars has two moons!
These are called Phobos and Deimos after, less surprisingly, Greek gods. More surprisingly and certainly more interestingly, neither moon resembles the perfect sphere you expect from a moon.
To help that sink in, today's link is a quick video shot by the stalwart Perseverance of Phobos passing in front of the sun. This is not the first time such an eclipse has been shot, but this instance comes with the highest fidelity. Providing you could safely stare at the sun (even given the additional portion of an astronomical unit's distance from it), imagine looking up and seeing this in silence.
