A lot of comments on Mars rovers or Moon landings, but it's important to remember that the planet NASA studies most is Earth. This is less about cutting flashy things like moonwalks and more about keeping communities in the dark on climate, weather, agriculture, pollution, natural hazards, and more.

They should read our new study. In Los Angeles Purple Air sensors are likely more accurate than the expensive sensors. www.science.org/doi/10.1126/...

Ask a Caltech Expert: Paul Wennberg on Environmental Hazards of Smoke Paul Wennberg discusses the air quality following the 2025 California fires and how to clean homes downwind of the fires.

If you're wondering about ash and smoke and soot and what to do to start cleanup, here is a great explainer from Caltech atmospheric scientist Paul Wennberg @paulowennberg.bsky.social

Far From the Fires, the Deadly Risks of Smoke Are Intensifying Researchers see a growing health danger from the vast plumes of pollution spawned by wildfires like the ones devastating Los Angeles.

Great to see our community open access studies linked by major newspapers. Here link to study by @gouwlab.bsky.social and colleagues in the NYTimes on hazards after the fires are extinguished.

Student Airborne Research Program - NASA Science An eight-week immersive summer internship for undergraduates to gain hands-on research experience.

Students interested in #NASA and/or planet Earth 🌍 should really consider applying for SARP.
