Last year, we reported on the discovery of an intriguing arrow-shaped rock on Mars by NASA's Perseverance rover. The rock contained chemical signatures and structures that could have been formed by ancient microbial life.

Last week, the Perseverance rover began an exciting new journey. Driving northwest of the Soroya ridge, Perseverance entered an area filled with a diverse range of boulders that the science team believes could hold clues to Mars's early history.

Research led by NASA suggests a habitable past on Mars based on the discovery of minerals in Martian rocks associated with life on Earth.
