Very interesting idea. I kinda hate the idea of reading something on a timer with other people during a meeting, but I do like the idea of digesting something written down and then discussing it.

Ever since reading about this memo meeting method, I have wanted to try it, but haven't had the guts to try to get people to do it. This article is nice confirmation that maybe it would be good to try. www.nature.com/articles/d41...

Some impressive artwork here. Gonna have to up our game for my next ISSI Team! 🙂

At ISSI, we like to think that our doors are open to some of the sharpest minds in space science and, as it turns out, to a bit of crayon-wielding creativity too. 🖍️🔭 See what happens when world-class research meets a more colourful kind of curiosity: www.issibern.ch/where-nobel-... 💙

I hinted that there would be more images from the Juice flyby, so here is the timelapse of the full event! It's always amazing to get these views of our fragile Blue Marble from the spacecraft we send out to explore the solar system! 🔭🧪 #planetsci

A successful Earth flyby improves Juice’s course to Jupiter Earlier today, Juice flew just 8640 km above the Indian Ocean and snapped these images with its onboard monitoring cameras. 1️⃣Africa, by Juice monitoring camera 2️⃣Madagascar, by Juice NavCam 3️⃣Moon, by Juice NavCam 🔭 🧪 #planetsci

Mostly black space, most of Earth visible at the top right of the image. Part of a spacecraft visible on the left.Part of the island of Madagascar in black and white.A crescent Moon, with about a quarter of the Moon showing. Many craters are visible.

a collaborator told me about a useful statistical measure and I went to look it up on wikipedia to find it was "prompted by the problem of identifying the similarities of skulls based on measurements"... oh...umm... right...!

where to look for "submoons" ("moonmoons" is funnier 😛) arxiv.org/abs/2609.03564 "Iapetus, Titan, Rhea, Phoebe, Callisto, and Ganymede are the most dynamically favorable submoon hosts"

Dynamically favorable hosts for submoons around Jupiter and Saturn

The long-term stability of small bodies orbiting natural satellites (submoons) in the Solar System has been previously investigated using an analytical approximation of a three-body problem, focusing ...

Mercury Transfer Module separation confirmed! 📡 ✅ Signal acquired via our Cebreros deep-space antenna confirms the spacecraft is healthy and operating as expected. The MPO and Mio spacecrafts are now on their way to Mercury orbit insertion on 21 November. Farewell, MTM. Mercury awaits. ☀️🛰️

Together, the stacked spacecraft travelled nine billion km, did 22 loops around the Sun and performed nine planetary flybys. MTM's propulsion system is dependent on Bepi's computer control, so after today, MTM will float around the Sun indefinitely. 🔭 🧪 #planetsci 2/3

This is a pleasing factoid: the Nancy Grace Roman space telescope is the same size and weight as a T-Rex! Countdown: 15 days to launch! 🚀 AUG 30, 2026 11:26 UTC ℹ️: science.nasa.gov/mission/roma...

Space projects running ahead of schedule? This is rare! Huge celebratory high-5's all round to the Nancy Grace Roman Space Telescope team, due for early launch this August 🥳 This beast will discover >100,000 planets orbiting distant stars and so so much more 🤩🧪🔭🛰️ ℹ️: science.nasa.gov/blogs/roman/...
