Great shot

A fantastic view from the Mars Curiosity Rover using ChemCam looking towards the distant Yardang Unit. Taken this week on Sol 4562.

The surface of Saturn’s moon Iapetus in the dark region “Cassini Regio” taken in September 2007 when Cassini passed to within 1,227 km. This dark blanket is only about a foot thick on average and reveals bright patches of ice when impacted.

Google should do a yearly “wrapped”… a guess at mine:

1. gas constant
2. gas constant “J/mol K”
3. Molar mass P2O5
4. How to disable AI in [insert any software or app]
5. How to enable macros in Excel

Here's a (probably) long and (certainly) intermittent thread covering the #geoscience research that's been done at Edinburgh Geosciences using X-ray #Microtomography to study Earth materials and processes. I'll post links to open source papers, but first a bit of background ...

Just submitted a manuscript for a project that has been almost 5 years in the making, and probably the work I’m most proud of to date… The best news is that I don’t need to look at it for a while

A spectrum, much like the last, except for even loss CO2 at 4.26 microns.

Last JWST moon of Saturn for a while: Mimas! aka the Deathstar. Turns out that Mimas looks an awful lot like it you took an ice cube, ground it up into 300 micron particles, and stuck it in your spectrometer. Also an oh-so-tiny trace of CO2 there marked in red. But otherwise: this is ice. 🔭🧪

In a vault behind glass, there is stored a C program from 1978:

#include <stdio.h>

main()
{
printf("goodbye, world\n");
}

When the time is right, we are to break the glass and run the program. It is to be the last C program.

Contemplating adding a list of memorised alt codes to my CV

Chilling after hearing his latest vlog this week

Was this from when he was a postdoc?

View of Hjørundfjorden from airplane

View of Nordfjord with Jostedalsbreen and Ålfotbreen glaciers from airplane

Oblique views of Hjørundfjorden, and Nordfjord with Jostedalsbreen and Ålfotbreen glaciers leaving Ålesund, Norway. Stunning geology both at ground level and from above!

Beach cobble stone showing deformation structure in 3D

Cool cobble

Briksdalsbreen glacier. Terminus was at lake level in 2007 😐🫠

Grateful to have one more rare glorious day in Scotland before leaving

Having been thinking a lot about cooling basalt, this is what I imagine the inside of my brain is looking like these days #staffa
