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.

Not sure where to post this- so, try the 'hot' posts and mods can move as needed-
It appears that the Juno probe's solar arrays inadvertently "sampled" Mars geology The space probe was pummeled and pitted by "Zodiacal Dust" which seems to be streaming off Mars. More amazing, Martian rocks are ground into fine dust, lifted by global Martian dust storms, tossed into space, constrained in a torus, only to spiral inward and float down to Earth. Even more amazing, with a ballpark estimate of of 60 tons of "space dust" per day drifting down to earth, https://www.popsci.com/60-tons-cosmic-dust-...arth-every-day/ that suggests Earth receives about 30 tons of Mars rock samples every day. They're just REALLY tiny and spread across the entire globe.
