Ralph Lorenz—Huygens showed that Titan can be wet, even at low latitudes. As Dragonfly flies across Titan, the odds it’ll land in mud are low (<1%), and if so, the stickiness will be again to sticky wheat dough (and Dragonfly could still takeoff). #AOGS2026

A photograph of a sketch in my notebook summarizing Ralph Lorenz’s talk at AOGS2026. The pen and pencil sketch shows two spacecraft on the surface of Titan: Huygens and Dragonfly (loosely to scale). The two grey spacecraft sit on a rock littered orange surface with a yellow hazy sky behind them. Next to Hogan’s, I have a zoom in the regular showing how the acoustic sensor suggested that the soil was damp, with liquid sweating out of it. On the right, I show a little insect of some reel, analog dunes, which very rarely can have intradune lakes form in particular particularly rainy seasons. Situations such as this are predicted to be very rare for Titan, but the Dragonfly mission is planned to handle it.

Google has also decided to effectively kill the desktop version of Google Earth Pro - which has been a genuinely useful mapping tool for many years. They’ve apparently decided those resources are better spent allowing users to burn AI credits on creating satellite imagery disinformation.

Get Google Earth Pro while you still can.

In an update on Tuesday, Google says it will block users from downloading its Google Earth Pro desktop app starting June 25th, 2027. People can continue to use the app after that date, which offers ac...

First video of gnarly rip current in Venice Beach today, with a Los Angeles County Lifeguard rescuing a young boy who was swept out to sea. It was all moving so fast!!!

I’d like to make it clear for all the people following me what the sheer gravity of the news is. Without this facility we can’t ensure constant communication with spacecraft beyond Earth orbit. If this facility is off-line, the Artemis program cannot send a crew to the Moon.

It appears this quake is in a zone with a seismic history and a reasonable chance of a magnitude 6 earthquake, but also a history of oil and gas exploration and presumably waste fluid disposal. Many of these are listed in the attached document as uncertain trigger. www.weather.gov/media/ama/ea...

Looks like a proper tectonic quake (now M5.1) in the Texas panhandle. Deep disposal well activity is a possible trigger but that's TBD. (earthquake.usgs.gov/earthquakes/...)

Can’t wait for everybody else to realize that sand is in fact not an infinite resource, especially the really clean quartz sand we use to make stuff with. Not all sand is the same!

Estimated rainfall through the week over Southwest Texas. As much as 25" to 30" of rain has fallen in the area of Uvalde, Knippa, Sabinal. Catastrophic flooding continues this morning along the Frio & Guadalupe Rivers and surrounding areas. #txwx

I haven't seen anyone note this yet, but just to stress. Since many proposals are on 3 year or longer timescales, only a fraction of NSFs budget is available for new proposals each year, something close to 30%. A 20-30% cut basically eliminates 2/3 or more of new proposals this year.

Exclusive: The National Science Foundation is trimming this year’s budgets for hundreds of its traditional basic science programs by roughly 20% to 30%, even though its overall budget is down just 3%. https://scim.ag/4xY2KCm

As someone who's spent an inordinate amount of time in Yellowstone geyser basins... you absolutely cannot stop the public from touching algae if they want to touch it. 😂

Oh look, NSF is sending out job ads to list servs in at least the Earth Sciences that are looking for Trump flunkies, more or less, to serve as program directors. This has gone out to multiple mailing lists from multiple NSF accounts.
