The journal Science published an article about the progress of the Perseverance sampling mission. It also stated that the project management is engaged in a key debate: should the rover sample only the crater and then return to the crater floor or also sample the ancient terrains beyond the crater?
For those who don't remember, the top two choices of the scientific community for sending Perseverance to were Jezero crater and the ancient terrain nearby. For a long time, the expectation that if healthy, the rover would leave the crater and sample both areas. (How lucky are we that they are next to each other?) Landing the craft to return the samples is simpler on the crater floor - lower elevation (denser atmosphere) and large flat areas. The debate was hinted at by the abstracts presented at the recent LPSC conference, where several argue for sampling beyond the crater.

It seems possible, given the health of the rover and how quickly it can move when it needs to, that they could perhaps go well beyond the crater rim, and still come back to Three Forks well before the sample return lander arrives there.
