The terrain is uneven, meaning that several of the cameras Ingenuity uses to assess its height can quickly go from "you're totally fine" to "pull up!" very quickly, which could easily lead it to crash.

According to, the nearby South Séítah region has many more sampling opportunities for the rover, but also an increased risk to both rover and helicopter. If Perseverance gets stuck, there's no one there to pull it out. There are mounds and dunes along the path that could snag the $2.7 billion rover, something you don't ever want to have happen if you can help it.

The challenge is that the terrain between where Perseverance is currently and the possible sites that it could sample isn't completely flat.

"Therefore, we will head to the next sampling location in South Séítah, the farthest point of this phase of our science campaign.' "Both the science and engineering teams believe that the uniqueness of this rock and its material properties are the dominant contributor to the difficulty in extracting a core from it," wrote Louise Jandura, Chief Engineer for Sampling & Caching at NASA-JPL, in a blog post last week.
