But bits of Mars’s two moons may already be circling the Red Planet, some of it in the form of nascent rings. “Phobos passing through these resonances would have changed that.”. "This research highlights even more ways that major impacts can affect a planetary body," said Richard Zurek of NASA's Jet Propulsion Laboratory, Pasadena, California. He is the project scientist for NASA’s Mars Reconnaissance Orbiter, whose gravity mapping provided support for the hypothesis that the northern lowlands were formed by a massive impact. "And now it's possible to study that material.".

But YES, very likely, Mars will one day have a ring system. That's the theory put forth by NASA-funded scientists at Purdue University, Lafayette, Indiana, whose findings were published in the journal Nature Geoscience.

As children, we learned about our solar system’s planets by certain characteristics — Jupiter is the largest, Saturn has rings, Mercury is closest to the sun. “That large impact would have blasted enough material off the surface of Mars to form a ring,” Hesselbrock said. Phobos, one of Mars’ moons, is getting closer to the planet. Minton and Hesselbrock will now focus their work on either the dynamics of the first set of rings that formed or the materials that have rained down on Mars from disintegration of moons. Also, Phobos would have had to form far from Mars and would have had to cross through the resonance of Deimos, the outer of Mars' two moons. Each time a moon broke apart and reformed from the resulting ring, its successor moon would be five times smaller than the last, according to the model, and debris would have rained down on the planet, possibly explaining enigmatic sedimentary deposits found near Mars’ equator. Phobos, one of Mars' moons, is getting closer to the planet. NASA's Perseverance rover carries a device to convert Martian air into oxygen that, if produced on a larger scale, could be used not just for breathing, but also for fuel. He is the project scientist for NASA's Mars Reconnaissance Orbiter, whose gravity mapping provided support for the hypothesis that the northern lowlands were formed by a massive impact. By passing through its resonance, Phobos would have altered Deimos’ orbit. This sequence of images from NASA’s Curiosity Mars rover shows one of Mars’ two moons, Phobos, passing directly in front of the other, Deimos, in 2013. “And now it’s possible to study that material.”. No, Mars does not currently have a ring or rings. Image credit: NASA/JPL-Caltech/Malin Space Science Systems/Texas A&M Univ. Mars is red, but it's possible that one of our closest neighbors also had rings at one point and may have them again someday. Over time, Mars' gravitational pull would have pulled that moon toward the planet until it reached the Roche limit, the distance within which a planet's tidal forces will break apart a celestial body that is held together only by gravity. Not right now, but maybe one day Purdue University. "You could have had kilometer-thick piles of moon sediment raining down on Mars in the early parts of the planet's history, and there are enigmatic sedimentary deposits on Mars with no explanation as to how they got there," Minton said. Other theories suggest that the impact with Mars that created the North Polar Basin led to the formation of Phobos 4.3 billion years ago, but Minton said it’s unlikely the moon could have lasted all that time. MOXIE Could Help Future Rockets Launch Off Mars. Depending on where the Roche limit is, Minton and Hesselbrock believe this cycle may have repeated between three and seven times over billions of years. Each time a moon broke apart and reformed from the resulting ring, its successor moon would be five times smaller than the last, according to the model, and debris would have rained down on the planet, possibly explaining enigmatic sedimentary deposits found near Mars' equator. As children, we learned about our solar system's planets by certain characteristics -- Jupiter is the largest, Saturn has rings, Mercury is closest to the sun. But Deimos' orbit is within one degree of Mars' equator, suggesting Phobos has had no effect on Deimos.
