Phobos shadow passage over Mount Sharp, Curiosity sol 1694
Phobos shadow passage over Mount Sharp, Curiosity sol 1694 Near Mars' equinoxes, the moons of Mars pass between the Sun and the planet, drawing a line of penumbral eclipses across the surface. Here, Phobos' penumbra passes across Mount Sharp, to the south of Curiosity, on sol 1694 (May 12, 2017). Two different Navcam images show the difference between the ordinary-lit mountain and the view when it's in Phobos' shadow. NASA / JPL / Fredk
