Mu cat trying to watch the fireworks. He's a bit short so not sure if he's seeing them. Happy fourth everyone.

Our lunar orbital radar prototype was the first instrument tested in the huge University of Arizona thermal vac chamber! Hopefully we will have an opportunity to send it to the moon. research.arizona.edu/news/prototy...

Baby owls 2026. There are 2 and they are growing fast.

A research team at LPL demonstrated that ground-penetrating radar mounted on drones can map the thickness of rocky debris covering glaciers on Earth. These results could help future astronauts locate accessible water locked in buried ice on Mars. news.arizona.edu/news/drone-r...

🚨 NASA scientists warn: critical equipment at Goddard Space Flight Center could be discarded during the shutdown, jeopardizing decades of Earth & space science missions. 📢 Act now: agu.quorum.us/campaign/146... #sciencepolicy #saveNASA

[BREAKING] The Planetary Society and 14 partner organizations released a joint letter calling for explicit NASA science protections in Congress's stopgap spending bill. Read it here: www.planetary.org/press-releas...

Venus is a Solar System enigma. Although Venus is similar in size and distance from the Sun to Earth, it has evolved very differently from our planet. Our #Envision mission will aim to solve some of the puzzle by thoroughly studying our closest neighbour. www.esa.int/Science_Expl... 🔭

Wow the banquet at #epscdps.

Wow the Venus talks are in a room with an organ! They should have told people in advance so they could plan more dramatic talks! #epscdps

Every conference facility has its quirks. In this case I was at Saturn (room) and need to head back toward the Sun (room) but am not sure how. Maybe I need help from a dynamicist! #epscdps2025

I'm sorry this looks extremely dangerous.

Please join us in congratulating Samantha Moruzzi, who today successfully defended her Ph.D. Dissertation, Geophysical Evolution of Sputnik Basin on Pluto. Congratulations, Samantha! 📸: Samantha is pictured with her advisor, Dr. Jeff Andrews-Hanna.

The REASON Ice Penetrating Radar produced good test data when we flew by Mars! All looking good for seeing inside #Europa in a few years. www.nasa.gov/missions/eur...

It's time to mark your calendars! The 2025 LPL Evening Lecture Series features "Space on Earth." You can attend any lecture in-person or virtually. We hope to see you there! lpl.arizona.edu/calendar/eve...

The first photos from the Vera Rubin Observatory are stunning — thanks in part to the University of Arizona, which helped build its mirror. Proud to see Arizona leading the way in space science.

Today, *every* living prior leader of NASA's science directorate have released a joint letter condemning the proposed cuts to NASA science. These individuals every administration from Reagan to Biden, and all believe these cuts are insanely destructive: www.planetary.org/press-releas...

The Senate reconciliation bill passed yesterday is separate from the annual appropriations process, which determines funding for our federal science agencies. Learn more about the differences here: aas.org/posts/news/2...

Another interstellar asteroid friend is traveling through the neighborhood! ☄️

What is the impact of the proposed mission terminations and cancellations on Arizona (U of A + ASU) Universities? These charts flag the missions with AZ participation and those impacted.

I really wish there were fewer mistakes in Arizona governance. Please everyone come to work and try to make sure you do your job correctly. Maybe double check the letters, just for example.

An update on the "Save NASA Science" campaign led by The Planetary Society @exploreplanets. Unrelated to TPS, I hear there is protested planned for NASA HQ on Monday morning 7-11 am to support the NASA Science budget.

PSI's Amanda Hendrix wrote a really great op-ed for the local Tucson newspaper about what's at stake in the fight against the president's budget request for NASA: tucson.com/opinion/colu...

Wow! Amazing!

This has just been weighing on me for weeks, and especially this week. I loved working at Goddard. People there were great and some of the most dedicated people I know. It's fundamentally non-partisan excellence in science and engineering. Everyone is busy there. And it will save virtually no money.

Take a look at the contribution to the commentary in Nature Astronomy by LPL graduate student Kayla Smith! www.nature.com/articles/s41...

Local Tucson news has a good piece on OSIRIS-APEX being zeroed out of the proposed NASA budget. www.kgun9.com/news/local-n...

In ~5 years, we as a species are on track to embark on an incredible era of discovery, unlocking the secrets of the planet Venus. The missions @ESA_Envision, DAVINCI, and VERITAS will reveal Venus as we have never seen her before. But why should YOU care about our sister world?

Thanks to the Rimfax team in Norway for 3D printing a model of the Rimfax antenna for the Lego Perseverance rover. Now it looks complete! Bonus chaos cat - cat of Mars2020.

Large sections of Sabino Canyon Recreation Area, Mount Lemmon and Madera Canyon, and parts of Mount Graham, would be eligible for selling off as part of proposed Senate legislation that

Also very nice area to walk around, with hiking trails in the area. Gardnos meteor park is about 2 hr 40 min drive from Oslo.

Had a great time over the last week at the Perseverance rover team meeting in Oslo and visiting Gardnos crater! Recommend stopping by if you are in Norway, you can see pre-cambrian impact breccia.

"welcome home to Tucson" 🌵

Super puff planets, what will people think of next! 😂🔮

Copied from EnVision's account on the Other Netnwork: Meet the @ESA_Envision VenSpec science team 👋! Scientists working on our three instruments, VenSpec-H, VenSpec-M & VenSpec-U, have joined forces at the LATMOS site in Guyancourt, France, to maximize their science output.

Our global petition to save NASA science closes this Thursday, and we’re just shy of 15,000 signatures! Every name counts, this petition will be hand-delivered to members of Congress. Add yours today, Save NASA Science. planet.ly/petition

Looking for one place to track what’s happening with NASA’s space science budget? 💡 Our Space Policy Advocacy Hub has you covered, with the latest letters, updates, and resources you need to stay informed. Check it out ➡️ www.planetary.org/save-nasa-sc...

Last week, NASA and NSF released their FY26 budget requests. We list the detailed impacts on the astronomical sciences in this blog post, and share how you can take action today. aas.org/posts/news/2... @policy.aas.org

This years crop of baby screetch owls has started coming out. As usual they are already pretty big.

Jezero Mons! Could explain where so much of the Jezero crater volcanic deposits come from. www.nature.com/articles/s43...

Also this looks like a useful (free) textbook in statistics: www.statlearning.com

1. Don’t unknowingly use data. When doing data science, you need to know, and understand (at least at some level), the data collection methods, and document them for later reference (write it down now and save yourself time later!).

I think a lot of people don't understand that in a world where everyone uses "AI" to vomit out statistically average text, the ability to use words uniquely becomes a premium skill and a critical differentiator.

Congrats on 50 years ESA!

Wow first time that I saw a Gila monster in my yard since coming to Tucson!
