History of Mars: Water Flows in Ancient Neretva Vallis (Animation) | NASA/JPL
An animation depicting what Neretva Vallis on Mars might have looked like billions of years ago: a flowing river flanked by sandy, rocky hills under the Sun.
This animation transitions through time, depicting the water disappearing in the Martian river valley Neretva Vallis until it reaches the present day, when the valley is entirely dry. The view pans to reveal NASA's Perseverance Mars rover with its robotic arm extended and about to sample the “Sapphire Canyon” sample cored from the rock “Cheyava Falls,” which was found in the “Bright Angel” formation, a set of rocky outcrops on the northern and southern edges of Neretva Vallis.
A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover is characterizing the planet's geology and past climate, paving the way for human exploration of the Red Planet, and is the first mission to collect and cache Martian rock and regolith (broken rock and dust).
