Also, it is fantastic that the EPA makes this information so accessible. It helps with decisions for everyone living in the area and is so important for people who are sensitive to poor air quality. We should continue to fund all of this!

Advice needed: A former student now in industry is asking about pros/cons of doing an industry-sponsored PhD, given the current climate and not getting in anywhere this cycle. I remember there was chatter about this a couple years ago but it's a good time to revive this chat. Please RT.

With spacecraft thrusters at top center, the rugged surface of the Moon lies below the Blue Ghost lander in this space age video frame. The view of the lunar far side was captured by the Firefly Aerospace lunar lander on February 24, following a maneuver to circularize its orbit about 100 kilometers above the lunar surface. The robotic lunar lander is scheduled to touch down tomorrow, Sunday, March 2, at 3:34am Eastern Time in the Mare Crisium impact basin on the lunar near side. In support of the Artemis campaign, Blue Ghost is set to deliver science and technology experiments to the Moon, part of NASA's Commercial Lunar Payload Services program. Blue Ghost's mission on the surface is planned to operate during the lunar daylight hours at the landing site, about 14 Earth days.

“At the height of the Los Angeles County wildfires, atmospheric concentrations of lead, a neurotoxin, reached 100 times average levels even miles from the flames, according to early detailed measurements... Levels of chlorine, which is also toxic at low concentrations, reached 40 times the average.”
