@mapperwocky@fosstodon.org @PaulHammond51 @65dBnoise Paul: what functionality is missing? Do you mean something on the map or around the map?

@65dBnoise @mapperwocky@fosstodon.org @PaulHammond51 the Perseverance page should have the latest data (just checked). Had a minor kerfluffle when my machine crashed mid-localization. 😅

So you can better describe the ants you see here are some common descriptive words for the exoskeletons of ants:

striate - many parallel grooves
tuberculate - little protrusions covering the surface
reticulate - split into irregular cells
glabrous - smooth
punctate/foveolate - covered in little round depressions
rugulose - wrinkled
pilosity - the degree of pilosity refers to how hairy the ant is
reclinate hairs - hairs that lay flat
tomentum - wooly hairs
clavate hairs - club-shaped hairs

1000 richest people are approched. "The end of the world is here. Time to go to your doomsday bunker", they are told. The billionaires nodded. They knew this was coming. They were prepared.

So they gathered their loved ones and locked themselves in luxury bunkers. No contact to outside world.

10 years later they emerge. The world has healed. The air is breathable, people are happy. "What was the catastrophy?" they ask the first person they meet.

She screams: "THEY GOT OUT!!!"

This is the Tianwen-1 landing site with the first few drives of the Zhurong rover. The background is a HiRISE image. Two names are informal and added by me, not by China. TAR is a Transverse Aeolian Ridge, what might be called a dune (but technically not). This was going to be the last of my Mars landing site images, but I have decided to add the final resting places of Spirit and Opportunity, taking us nicely up to Christmas.

This map shows the Tianwen-1 lander and the path of the Zhurong rover for its first month of operations on Mars.

dont feel bad for using your local library and its services if you have a good local library system. literally use the hell out of its services if you can, it gives them justification to keep getting funding

@archaeohistories such incredible detail!

The largest animal rock petroglyphs in the world; known as 'Dabous Giraffes', located in Air Massif, Niger.

The carvings (6m in height) are believed to have been done between 12000-7000 BC, during African Humid Period (14600-5000 years ago), when this region was less arid, and Sahara was a vast savannah, that streched thousands of miles. There are also remains of petrified wood found in the area, which gave evidence that region could sustain animal and human life.

Hot stuff in the lab today 🌶️

I performed geologist’s alchemy. I turned powdered chemicals into a rock! Here is the platinum crucible coming out of the furnace at 1400 °C.

“Five million more American kids fell into poverty last year. Or maybe it’s more accurate to say they were pushed.”

“Last year, one of the most successful anti-poverty programs ever enacted — as part of President Biden's American Rescue Plan — ended because Congress chose to end it. The consequence? The child poverty rate more than doubled.”

Just dug up this side project I did in November of last year and gave it a couple of tweaks (accidentally left on a layer that I meant to turn off). Still pretty pleased with how it turned out.

Just when I thought Canada couldn't get any more Canada: there's a hockey stick in this beaver dam.

Beaver dam between two ponds of water in the evening. A hockey stick with a broken paddle sits among the branches of the dam. A beaver swims through the still water next to the dam.

#Venus doesn't have much (if any) #calcite, no limestone, and little if any other carbonates.

Those carbonates instead are CO2 in Venus' atmosphere -over 90 times our atmospheric pressure. This gives Venus a surface temperature of 475°C.

Poor Venus.

Calcite for a habitable planet!
