(CNN) Mars has two small, funky-looking moons with strange orbits, and they may suggest that the red planet once had rings, like some of the larger planets in our solar system.

Mars's moon Phobos may someday turn back into a ring around the planet | New Scientist
For Mars's moon Phobos, it's dust to dust. There is evidence that the misshapen little moon has gone through a cycle of being smashed up and spreading into a ring around Mars before coalescing into a solid moon again.
This ring-moon cycle was proposed in 2017, and new simulations by Matija Ćuk at the SETI Institute in California, and his colleagues show that such a cycle for Phobos may have forced Mars's other moon, Deimos, …
Curiosity rover finds evidence for ancient ice-covered lake on Mars | Space | EarthSky
Scientists studying data from the Curiosity rover have found evidence for an ancient ice-covered lake in Gale Crater on Mars. The findings support the theory of alternating warmer and colder climates on early Mars.
Artist’s concept of Gale Crater when it was filled by a lake a few billion years ago. The Curiosity rover had previous evidence for the lake or series of lakes over time. Now a new study suggests that the lake could have been covered by ice during colder climate periods. Image via NASA / JPL-Caltech/ ESA/ DLR/ FU Berlin/ MSSS.

The Extraordinary Sample-Gathering System of NASA's Perseverance Mars Rover – NASA's Mars
Two astronauts collected Moon rocks on Apollo 11. It will take three robotic systems working together to gather up the first Mars rock samples for return to Earth.
The samples Apollo 11 brought back to Earth from the Moon were humanity's first from another celestial body. NASA's upcoming Mars 2020 Perseverance rover mission will collect the first samples from another planet (the red one) for return to Earth by subsequent missions. In place of astronauts, the Perseverance rover will rely on the most complex, capable and cleanest mechanism ever to be sent into space, the Sample Caching System.
