Composite of several images captured by Europa Clipper’s thermal imager. Red areas are about 32 degrees Fahrenheit (0 degrees C), and purple regions are about -190 F (125 C).

My wife and I baked a scrumptious gluten-free banana cream pie for the π-Day celebration accompanying the #EuropaClipper Post-Launch Assessment Review (PLAR) today! It's the first time either of us has made a pie, and we're very proud. I'm even more proud of the PLAR's outstanding presenters. #PiDay

Reflection of sunset in the window as my wife and I watched a beautiful moonrise from inside our home the other evening.

Unfortunately, no Miracle Tickets available for the Grateful Dead honorees at the Kennedy Center tonight—not even a Kind Grilled Cheese in sight. But at least it’s lit appropriately for the Band Beyond Description!

Hello, Bluesky! The air seems much more refreshing over here, without that cesspool stench. For my first post: kittens! (An LA friend’s, not mine.) Want one? Or two?
