A day late, but this is one of the first images taken of Earth from space. Ever. It was acquired from an altitude of 105 km (five times higher than the previous record) eighty years ago, on 24 October 1946, with a 35 mm camera mounted on a V-2 rocket launched from the White Sands Missile Range.

Speaking of Saturn photobombing pics of moons (see my earlier post today)... This video sequence, taken in 2007 by astronomer Jan Koet, shows the Moon moving in the sky—revealing giant Saturn, almost 1.5 billion km away. The video is at twice actual speed.

At the VEXAG 2026 meeting in Boulder just now, we've learned that NASA's VERITAS mission has been scheduled for a November 2032 launch. Folks, this is CRAZY good news. Earlier this year we were concerned that NASA would *cancel* VERITAS!

I've long had a fascination with Bellcomm, the think-tank Bell System created at NASA's request in 1962. Often it's called NASA's "Apollo planning contractor," but it studied much more than that. There was, for example, this mad crewed Mars concept. spaceflighthistory.blogspot.com/2021/12/mssr...

Squirrels on suicide missions have knocked out power to Castle Rock, Colorado twice this week. Our investigation has revealed a century of squirrel attacks covered up by the pro-squirrel media.

"The little turtles are looking at the Moon and the Earth through the porthole of their spacecraft. An artistic interpretation of that very journey aboard the ‘Zond-5’ spacecraft." (The turtles were actually glued to posts, to stop them from moving around).

Here is a fun little animation showing how the shadows on Phobos change over the course of its short (7h 39m) day. The other image was actually taken two weeks ago, but since Phobos is tidally locked to Mars, it doesn't really matter. 🔭🧪

Yesterday, the NASA Perseverance rover captured this view of Mars' moon Phobos. The large crater Stickney is visible in the top left of the moon. 🔭🧪 flic.kr/p/2sxUsq4 Credit: NASA/JPL-Caltech/ASU/Simeon Schmauß

Let's learn some surprising things about hummingbird tongues. First, as you can see, their tongues are forked & feathery, highly specialized for lapping up their liquid diet of nectar. But it gets weirder up close!

100%. The notion that the President can conjure up revenue streams that free him from constitutional congressional control over spending is far more alarming than just another questionable spending proposal.

W/o getting drawn into the "seriously or literally" / "it'll never happen" trap, we need to stomp *hard* on the continuing effort to undermine Article 1 power of the purse by saying that this or that revenue stream makes something outside the normal budget process. 1/ www.nbcnews.com/business/eco...

Astrophotographer Adam (AJ) Smadi caught this image a few hours ago from Washington state. A thin crescent Moon, sunlight illuminating the rugged lunar surface. And 2,400 times farther away—and on the other side of the Sun—mighty Jupiter, and its moons Io (left) and Ganymede (right).

Every time I hear a fuss about "we should stop using Mercator projection maps!" I wonder who in the world was still getting fooled by Mercator projection maps. National Geographic started using Van Der Grinten in *1922* and Robertson in the 80s.

The U.N. has backed a new map showing Africa in its true relative size, with the U.S. standing alone in opposition. n.pr/4cq8Sdp

People may legitimately ding Bluesky for being a politically homogenous echo chamber, but I’ll say one thing for it: I’m still getting likes on a pun I made several months ago, which would never happen on Twitter.

Ward Maps in Cambridge is an excellent map store. It's BIG and has a ton of delightful MBTA merch that is creative and fun. I'm suspicious of most antique dealers who are just scavengers of history but Ward's owner is a real maker because he cowrote an excellent book about Boston map history.

🌒 En fouillant les images de Yutu-2 🇨🇳, j'ai découvert que l'atterrisseur Chang'e 4 inclinait ses panneaux solaires pour les orienter vers le Soleil 🤯 Cette animation montre deux photos prises depuis le même endroit, à 7 jours d'écart (1/4 de rotation de la Lune, l'équivalent de 6h sur Terre)

📷🔭 An amazing achievement! Astrophotographer Charline Giroud has captured an incredible image of China’s Tiangong Space Station passing over Spain at 8:20 AM UTC Aug 9. A stunning view from here on Earth of a truly “Heavenly Palace” — Tiangong. 🛰️🌍🌌

As a kid I was fascinated by a book about the voyage of the Kon-Tiki, when Norwegian adventurer Thor Heyerdahl and a few friends set out to prove his theory that Polynesia was populated from South America by building a traditional Peruvian balsa raft and floating across the Pacific in 1947.

I recently discovered that the 1950 documentary about their adventure, mostly from film they shot on the voyage, is available on Amazon Prime. Worth checking out if you’re into adventure travel. They saw a lot more wildlife on a quiet floating raft than one would on a powered ship.

I really recommend the 2022 documentary “It’s Quieter in the Twilight,” which profiles the scientists working in relative obscurity to keep the Voyager spacecraft operating—many of them past retirement age, but unwilling to quit until the Voyagers do. It was very sweet and thought-provoking.

51 years ago I painted a trio of Viking related works for NASA HQ including the widely reproduced one of the landing on Mars. I have reimagined the Landing portrayal in updated form using digital methods of visualization and painting. I chose the same angle but with reality replacing anticipation.

Whenever I read about discoveries in the Amazon, I recall a lecture I saw by an archeologist of South American cultures. He said the reason we know so much about the civilizations of Peru and so little about the ancient Amazon is not because the Amazon was empty, but because Peru is easier to study.

A paper in Nature reports that aerial imaging has detected 432 patterns called earthworks, on the ground in southwestern Amazonia. The findings were made in an area previously inhabited by the ancient Aquiry civilization of southwestern Amazonia. go.nature.com/4be3R7e 🏺🧪

A spaceship entered Earth's orbit and broadcast a message: "We are the Interstellar Library. Do you want to swap? We have thousands of stories." There were many replies. The library was silent for a whole day, then: "What do you mean, 'We have millions'?"

"After years of painstaking research in ancient grimoires and microcontroller logic, I have perfected it!" the professor exclaimed. "What?" "All printers are possessed. I've made a PDF which performs an exorcism." "So you print it, and then the printer works?" "Yes!" "What if it won't print?"

"You have tampered in the Gods' domain!" the god shouted. "Well, maybe, but you gods tamper in the human domain all the time!" "That's... That's different!" "How?" "We are Gods! It's what we do!" "And we are human. Likewise." "I..." The god sighed. "Fair. But keep it quiet, okay?"

Today in 1976, 50 years ago, the Viking 1 lander touched down on Chryse Planitia, Mars, and became humanity's first long term outpost on another world (the Venera Venus landers lasted an hour or two, Viking 1 lasted over 6 years).
