NASA’s Perseverance Mars rover used its Mastcam-Z 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.

Several Mars rovers have observed Phobos crossing in front of the Sun over the past 18 years. Spirit and Opportunity made the first observations back in 2004; Curiosity in 2019 was the first to record video of the event. Each time these eclipses are observed, they allow scientists to measure subtle shifts in Phobos’ orbit over time. The moon’s tidal forces pull on the deep interior of the Red Planet, as well as its crust and mantle; 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.

Watch NASA’s SpaceX Crew-4 astronauts arrive at the International Space Station aboard their Dragon spacecraft Freedom. Docking is scheduled for approximately 7:40 p.m. EDT (23:40 UTC).

Once aboard the orbiting laboratory, astronauts Bob Hines, Jessica Watkins, and Kjell Lindgren of NASA, alongside Samantha Cristoforetti of ESA (European Space Agency), will spend nearly six months conducting new scientific research in areas such as materials science, health technologies, and plant science to prepare for human exploration beyond low-Earth orbit and to benefit life on Earth.
