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. Science article: https://www.science.org/content/article/nas...ines-signs-life Relevant LPSC abstracts: https://www.hou.usra.edu/meetings/lpsc2024/pdf/1336.pdf https://www.hou.usra.edu/meetings/lpsc2024/pdf/2079.pdf https://www.hou.usra.edu/meetings/lpsc2024/pdf/2377.pdf Note: I personally (for all that doesn't matter) want to see Perseverance go well 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.

John Not sure where Three Forks is. This is the map from the abstract in my post above. You can see the current rover position, which I think has taken ~25 km to get there. The highest priority location to go to for this and the other abstracts is Monument Valley. As you can see, it is a long distance, and even more if the rover has to return to the crater floor. I'm wondering if even the Northwest and Southwest Rim locations would be considered within reach of the rover has to return to the crater floor. -------------------- |

Not sure where Three Forks is. With all the maps people have made, you'd think this would be an easier question to answer, but this is where I think it is from the JPL map (which has crappy labeling options BTW). (The little green blob above where I added the "depot" label.) It's not clear if the rover has to make it back there for MSR, but the farther away we get, the more risk-adverse I suspect people will become. -------------------- Disclaimer: This post is based on public information only.
