Testing. Does everyone here see my handle the same as before? I noticed just now on my profile page that it had “Invalid handle”. I went into the settings and set it to my original handle and it seems fine now… weird.

Artemis II astronauts race to set a new distance record from Earth and behold the moon's far side The Artemis II astronauts are racing toward a new distance record on their moon flyby. Apollo 13's crew currently holds the record for the humans traveling the farthest from Earth.

BREAKING: Artemis II breaks Apollo 13’s distance record as humans travel farther from Earth than ever before.

I don’t know who needs to hear this but the dark side of the moon and the far side of the moon are two different concepts. Far side: side always facing away from Earth. Dark side: always changing as the moon rotates on its axis once every 27.3 days. They coincide only when the moon is full.

A full disc image of Earth, as seen from the Orion Crew Module. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in place from reflected light. At lower left, a large brown landmass is Africa, with Spain and Portugal with twinkling lights where the planet curves. At top right, auroras glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space (pic: NASA/R.Wiseman)

More context on this #Artemis II image:

* This is the night side, lit by moonlight. You can see city lights in Spain & Portugal, & a sliver of day at lower right

* The Sun is entirely behind Earth, which makes it a kind of solar eclipse, but w/ Earth doing the eclipsing instead of the Moon:

This essay is fantastic. It articulates almost perfectly my feelings about both the promises and pitfalls of generative AI in scientific work. So many excellent points, but to sum up: genAI can be a great tool, but cannot replace true learning that comes from trying (and failing) at doing science.

That being said, even if I did, I would have pulled off somewhere to watch the Artemis II launch!

It was great to visit Norman and catch up with some friends and colleagues at the VORTEX-USA workshop. On the plane now just as a tornado watch was issued. Wish I could stay and chase!

Me: Runs a quick-and-dirty idealized supercell simulation of a case just to see if it’ll work.

Result: Simulation looks amazingly close to real storm.

Me: Realizes that I made a mistake in some namelist parameter or another, fixes it, and runs it again.

Result: Storm looks like garbage…
