What aspects on mars makes it difficult for the mars rover to navigate the terrain?

Mars presents several challenges for rover navigation due to its rugged terrain, which includes steep slopes, loose sand, and large rocks. The thin atmosphere results in less aerodynamic drag, making it harder for rovers to slow down during descent. Additionally, the dust storms that can occur frequently obscure visibility and impact solar power generation. Finally, the lack of GPS on Mars necessitates reliance on onboard sensors and cameras, which can complicate navigation.
