The red planet Mars is destined to become the ringed planet within 40 million years’ time, when its largest moon Phobos is torn apart, according to two scientists from the University of California, Berkeley.

Analysing gravity data from the Curiosity Mars rover, researchers have found Gale Crater might not have been completely filled in the distant past.

New findings using data from NASA’s Mars Reconnaissance Orbiter show that gullies on modern Mars are likely not being formed by flowing liquid water. This new evidence will allow researchers to further narrow theories about how Martian gullies form, and reveal more details about Mars’ recent geologic processes.
