While weather at the launchsite is looking much better for the NG-2 launch tomorrow, weather in space is not, with a G4 rated geomagnetic storm set to hit Earth right around launch. Weather in the landing zone is also not looking too great with moderate risk.

Why are planetary scientists, astrobiologists and and SETI scientists so negative (pissed off, even) about Avi Loeb’s repeated claims that 3I/Atlas may be an invading alien spaceship?
