Happy New Years from Mars. It's the first day of the new Martian year, which lasts 687 Earth days. According to the internationally adopted timekeeping system, this is Mars year 39. The Curiosity rover sent down this view from Gale Crater today.

This is a cool photo of Venus! Photographed through the rings of Saturn.
A complex, curving pattern of lines that make up Saturn's vast ring system, in various gold and grey hues. The white arc at right is the limb of the planet itself. A tiny point of light is just upper right of centre.

It's too depressing and obnoxious to write about, but virtually all of the doomy/horny AI hyperventilating is transparently displaced anxiety about our fucked climate and political situation. Even rich idiots know it's bad and being permitted to get worse. They're trying to write their own ending.
