Wohoo! New handle: works! 😊😊😊 In case you are not aware, this is a neat feature of Bluesky: you can switch your handle to a domain which you own (see below for instructions).

[Scene is a kitchen - a middle aged woman called JANET is boiling peas at the stove. A younger more colourfully dressed woman named LIZ approached her.] JANET: Ugh... LIZ: What's up? JANET: I am so bored of cooking peas! LIZ: Have you tried... AI peas? JANET: AI peas? LIZ: They're peas with AI! [Liz holds up to us a packet of peas labelled: Pea-i AI - Peas with AI]. LIZ: Al-powered peas harness the potential of your peas JANET: What LIZ [Now a voiceover as we cut to a whizzy technology diagram of peas all connected by meaningless dotted lines] Why not take your peas to the next level with Al Peas' new Al tools to power your peas? [Show a techno diagram of a pea with a label reading 'AI' pointing to a random zone in it] LIZ: Each pea has Al in a way we haven't quite worked out yet but it's fine [Show Janet and Liz now in a Matrix-style world of peas] LIZ: With Al peas you can supercharge productivity and make AI work for your peas! JANET: What LIZ: Shut up LIZ: Our game-changing Pea-Al gives you the freedom to unlock the potential of the power of the future of your peas workflow From opening the bag of peas to boiling the peas to eating the peas To spending millions on adding Al to the peas and then having to work out what that even means. JANET: Is it really necessary to- LIZ [Grabbing Janet by the collar]: THE PEAS HAVE GOT AI, JANET [Cut to an advert ending screen, with the bag of peas and the slogan: AI PEAS: Just 'Peas' for god's sake buy the AI peas.

"For the first time in the history of this war, Ukraine has captured an enemy position using only ground robots and drones. The occupiers surrendered. The operation was carried out without infantry participation and with zero losses on our side." - Zelenskyy.

Inded at 2222 UTC the Chinese Space Station, whose lower inclination orbit is a better match to the track of the sublunar point on the Earth, was at 419656km from Artemis 2, an even larger distance. It was over New Orleans at the time.

A Mercury rover following the terminator is an interesting idea - but why not just land it at the poles (and keep it there) where it's always near the terminator? This would also be the opportunity to explore the radio-bright volatile deposits...

That is perhaps pushing it, given the general rarity of dinosaur bones, but then, the K-Pg impact *was* the largest (known) impact in the Phanerozoic, so who knows what got ejected along all those Yucatan rocks!

Ejected material is probably going to be very old on average (ejected Gyrs ago, perhaps even from the Archean, when the impact fluy was higher), so perhaps you could use both Sm-Nd chronometers...

Just different! Nothing comparable for Earths ancient atmosphere. Cave ice should be really interesting: every time the Moon accretes a volatile-rich impactor, it gets a very thin temporary atmosphere, which then should condense onto such ice deposits. They should be long-term stable, so...

That is a very legitimate but also very expensive experiment...

The lunar surface is an archive of Earth history: e.g. there should be plenty of rocks ejected by impacts in Earths deep past. Similar for the ice deposits, in particular in caves (protected from impact gardening). The history of Earths atmosphere is likely imprinted in the regolith, too...

How would a radio telescope fare in an environment where there is a lot of dry, angular dust with plenty of static charges?

Earthset from Artemis II. I am overcome.

In just a few hours (7:07 pm eastern), humans will officially set the record for the furthest our species has ever traveled from our home planet Earth (slightly further than Apollo 13 due to the specific flight path around the Moon) - which is pretty amazing

It's the that contains a primordial black hole in its core...

Öl für 100 € das Fass ist nicht wettbewerbsfähig mit erneuerbaren Energien erzeugt in Deutschland. Wer durch Subventionen die Marktpreise jetzt senkt, auf Rechnung aller Steuerzahler, baut die Abhängigkeit von Öl und Gas aus und stützt die Autokraten der Welt: die Mullahs, Putin, Trump. Er vergibt wieder eine Chance für eine schnellere Dekarbonisierung durch Erneuerbare, produziert in Deutschland. Eine Chance für mehr Energieunabhängigkeit. Ein Barrel Öl kostet aktuell rund 100 € und enthält etwa 1.600 kWh Energie. Genau diese Energiemenge lässt sich durch Solarstrom in Deutschland heute für rund 50 € erzeugen - also für die Hälfte. Dafür braucht es lediglich eine Solarfläche von etwa sieben Quadratmetern. Jahr für Jahr erzeugt diese Fläche dieses „Fass" Energie - ohne weitere Kosten 40 oder 50 Jahre lang oder vielleicht länger. Und trotzdem hält sich bis heute das Märchen, Erneuerbare seien zu teuer. Vor diesem Hintergrund ist es kaum noch rational, Öl aus Iran, Russland oder anderen weit entfernten Ländern nach Deutschland zu verschiffen. Wer daran festhält, verteidigt kein Erfolgsmodell, sondern eine gefährliche Abhängigkeit. Erst diese Abhängigkeit gibt den Mullahs die Macht dem iranischen Volk menschenunwürdige Lebensbedingungen zuzumuten und Israel mit der Auslöschung zu drohen. Nicht nur meine Meinung, wie die Diskussionsrunde bei Markus Lanz mit namhaften deutschen Ökonomen zeigt. Hier geht's zur Sendung: https://lnkd.in/dwDWwbWq

View of a part of a modern, generally black building, with lowered shades, on a sunny day in spring. The lines formed by the windows and shades are all slightly and chaotically tilted against one another.

Needless nightmare agression of some architect against people with OCD... 🤨

At the very least! Only two which cover at least a pixel...

Annotation of all the stars (and the planet Venus) visible in the background around the image of Earth in the new nighttime view of our planet from Artemis II.

There is a full universe behind that wonderful new Artemis II "Night Marble" view of Earth.

Here's a breakdown of the stars (and one planet) in the field of view. Look at us! Just a planet hanging out in space.

Does anyone know what the bright dot in the lower right is? Venus?

Hello, World - NASA NASA astronaut and Artemis II Commander Reid Wiseman took this picture of Earth from the Orion spacecraft's window after completing the translunar injection

My current over/under for the next US landing on the Moon is mid-2030 with a BlueOrigin lander. My current over/under for the first Chinese landing on the Moon is early 2031. 🌔

That was a beautiful launch! 😊 Now bed time for Europeans... I'll show the launch clip to the kids first thing tomorrow morning.

I wish the Artemis II crew all the best! 🌍🚀🌔Although I am a proponent of human space exploration (as you may have noticed😉), I think Artemis is a very wasteful and not very visionary project. But you know, unlike some supposedly less wasteful and more visionary space projects, it gets the job done!
