Valantinas recognized his team was not the first to consider ferrihydrite as a possible reason for the coloring of Mars.

discovery of widespread ferrihydrite suggests Mars once held liquid water that would have made it possible for the planet to support some form of life.

Perseverance rover,” Mustard said. He added, “When we get those back, we will be able to check whether our theory about ferrihydrite is correct."
