This thread is for those rockhounds among us to discuss the new terrain we'll see as Perseverance scoots around her new home. Let's get dirty & technical!
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

this is a high-level description of the regional geology of Jezero with the relative ages:

this is a high-level description of the regional geology of Jezero with the relative ages: Good summary- TLDR version- Exploring Mars is like "Russian Dolls with logarithmic crater sizes. 1) A lunar sized body obliterated the entire northern polar region of Mars leaving the "North Polar Basin." This impact is about the same class as the collision that created the Earth's moon. 2) At the southern edge of the "North Polar Basin" a smaller impact creates Isidris basin, roughly 950 miles across. This impact crater is about 7x the diameter of the 'dinosaur killer' crater at Chicxulub. 3) At the western edge of the Isidris impact basin, an impact created Jezro crater, about 30 miles across. This is roughly comparable to the size of the "Chesapeake Bay" impact crater on the US east coast. 4) Perseverance landed east of "Belva Crater" which is an impact crater on the delta deposits that is roughly the size of "Meteor Crater" in Arizona. |
