Shuang Yang—Chang’e 7 will land near the Moon’s south pole Shackleton crater later this year and deploy (via tether) a seismometer that is planned to survive for 8 years. This might be the first node of a long-lived *international* geophysical network! #AOGS2026

A photograph of my notebook showing a sketch of Shuang Yang (Chinese Academy of Science) talk at AOGS. It shows a low, oblique shot of the Chang’e 7 lander, landed on the Moon, as it lowers its seismometers (SP + VBB) to the surface of the Moon from the bottom of the lander. The seismometer will survive up to 8 years through use of an RHU.

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.

CNSA’s Tianwen-1 mission has recently released new images of Mars, including this view of the Charitum Montes in the southern rim of Argyre Planitia. Full size 6K & more info: flic.kr/p/2ssvpEm Image Processing: Andrea Luck Raw data: CNSA/CLEP/PEC/MoRIC Mosaic of 4 images 2025-12-04 235km altitude

A satellite view of the Charitum Montes mountain range, with rusty brown peaks and ridges contrasting against more soft cream coloured plains. Bright seasonal frost blankets much of the slopes in varying intensity altering the usual rusty reddish colour of mars and contrasting with dark valleys and scattered impact craters.

One of NASA's twin Mars-bound ESCAPADE spacecraft captured Earth and the Moon from 363K miles (584K km) away. In visible light, both appear as slim crescents. But switch to thermal infrared and it’s a different picture... 1/2

Against black space, Earth appears at left as a thin white-green crescent lit along its right edge. The Moon, slightly smaller and dimmer, sits at upper right as a matching tan crescent lit on the same side. Only a sliver of each world catches sunlight; the rest of both disks is lost in darkness.In infrared, Earth glows with heat represented by warm colors, while the Moon remains mostly dark.

True color processing of Mars: ten years apart, Hubble and Psyche captured roughly the same region. You can see Sinus Sabaeus, with Arabia Terra above and the South Polar cap below.
