Perseverance Mars rover bags 12th Red Planet rock sample

Catastrophe

"Science begets knowledge, opinion ignorance.
The first eight rock samples that Perseverance collected — from September 2021 to March of this year — were volcanic in origin, according to the mission team's sample log(opens in new tab). But the last four, which were gathered between July 7 and Wednesday, all come from sedimentary rocks.
As that change suggests, Perseverance is now exploring a remnant of the delta, examining layered rock formations that built up over time as silt fell out of Jezero's ancient river. Such deposits are more likely than volcanic ones to harbor organic compounds and other possible signs of Mars life, if it ever existed, Perseverance team members have said. So it's not surprising that the sample-collecting pace has now picked up.
