Experts say it means even more wastewater is spreading underground, poisoning the state’s water supply.

Last night, NASA's Perseverance rover looked up at the night sky once more, to capture interstellar #comet 3I/Atlas flying by the red planet.
The distance was "only" 0.2 AU or 30 Mio km, far closer than the comet ever got to Earth. 🔭 #3IAtlas

No Avi, that Perseverance Navcam picture you posted isn't showing 3I/Atlas, it's just Phobos, the brighter one of Mars' moons.
If you were even half the expert you think you are, this possibility should have been quite obvious and worth mentioning.
