Watching A Phobos "Eclipse" -- From Perseverance's Mast Cam, On Mars...


This is pretty cool, and under a minute in length. It clearly demonstrates how non-spherical, and rather egg-like. . . Phobos is, as well:



. . .NASA’s Perseverance Mars rover used its camera system to shoot video of Phobos, one of Mars’ two moons, eclipsing the Sun. It’s the most zoomed-in, highest frame-rate observation of a Phobos solar eclipse ever taken from the Martian surface. . . .

Captured with Perseverance’s next-generation Mastcam-Z camera on April 2, the 397th Martian day, or sol, of the mission, the eclipse lasted a little over 40 seconds -- much shorter than a typical solar eclipse involving Earth’s Moon. Phobos is about 157 times smaller than Earth’s Moon. Mars’ other moon, Deimos, is even smaller. . . .


Yep -- that is pretty darn cool! She may be. . . tiny, but she is mighty, too. . . G'night now, to all of good will. . . .
