This is a full 1:1 scale render of Ramanathan Crater, processed directly from raw, uncompressed NASA HiRISE PDS source files (Float32 IMG). No aggressive smoothing, no lossy compression, and elevation data in real-time.

I have been working on visualizing the appearance of proposed space mirrors on the night skies. As the beam approaches it appears as a column of light emerging from the darkness. At the beam center of a 600 km high 54 m. mirror the reflection gives a light similar to that of 38 Full Moons, 9.5 Lux.

On 23 September, the European-Chinese SMILE mission was declared ready for science operations, after launching on 19 May and reaching its target orbit on 20 June. The mission will study how Earth responds to the charged particles carried by the solar wind.

The Sunset of September 27, 2026 was an epic spectacle whose intensity and beauty were memorable. The cloud ceiling had a wide opening toward the West that admitted Sunlight which underwent progressive color changes as it briefly in turn illuminated layers of otherwise invisible cloud textures.

Wow!

China’s Tiangong Space Station crosses in front of Jupiter in this remarkable astrophotography shot. Just hundreds of kilometres above Earth, Tiangong appears in front of Jupiter, a world hundreds of millions of kilometres away. Captured by 沈老思347

Mars has some spectacularly insanely huge features - towering volcanoes, deep valleys, vast deserts - but kneel down in the cinnamon-hued dust and you'll also see it has exquisitely beautiful smaller features on its surface too... Sept 14th Curiosity images credit: NASA/JPL-Caltech/S Atkinson

The Tianwen-3, China's first Mars sample-return mission, is progressing smoothly, entering the prototype development phase with multiple technical breakthroughs and with scientific preparations underway simultaneously, said the mission's chief scientist on Sept 3.

An overhead view of the Viking 2 landing site, based on the surface photography and available maps of the sample field and various references. This was drawn with ink on a scratchboard sheet which had a printed gray dot screen on it, scraping away the ink for the lighter tones and highlights.

1/2 China has established a two-way high-speed laser link between Earth and the Moon, spanning over 400,000 km. With a 100 Mbps downlink, an 8K image could be transmitted in just ~12 seconds. 🌕

My portrayal of the Partial Lunar Eclipse of August 27-28, 2026. These were painted in Photoshop based on my observations through a 10 inch telescope and binoculars. Among the variable clouds I saw just enough of the event to get the observation I wanted, a look at the colors in the Earth shadow.

On this date, August 23 1966, The Lunar Orbiter 1 spacecraft obtained this first view of Earth from Lunar orbit. On the left is my treatment of the the wider angle photo taken the same time as the more widely circulated high res image. Also a contemporary poster describing the photo's context.

During the recent Total Solar Eclipse the South Korean Danuri spacecraft obtained a nice view of Earth from Lunar orbit with the Moons shadow just visible on Earth. Here is their image, with attribution added, my colorized version and the nearly simultaneous EPIC-DSCOVR image used for the color.

🌕 Countdown to China’s August 2026 Chang’e-7 Moon mission! - Launched in 2010, Chang’e-2 mapped the Moon in 7m detail, then travelled to the Sun–Earth L2 point to test deep-space navigation. In 2012, it flew within 1km of asteroid Toutatis, capturing detailed images.

📍🌕 China has completed an updated 1:5 million-scale geologic map of the entire Moon, the Institute of Geology said. A major scientific update from the 2024 version, it incorporates new research and significantly revises our understanding of the Moon’s geologic history.

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.

This is a fantastic essay. Read it If you have any interest in satellite imagery. “Who to Trust, Google or the Russian MoD? In 2015, that was a rhetorical question. Not anymore.” By @henkvaness.bsky.social

Alison Killing@alisonkilling.bsky.social

This is wildly irresponsible of Google - allowing people to create AI generated satellite images. Satellite imagery has always been such a useful and reliable source because it came from reliable sources, but now Google is messing with it at source. www.digitaldigging.org/p/how-to-pla...

🚀🌕 Sunday, August 23rd at 12:00 AM UTC Is Lift Off for China's Chang'e 7 mission. Which will explore the Moon's south pole, targeting the rim of Shackleton Crater. Its main goal is to search for water ice hidden inside permanently shadowed craters—an important resource for future lunar exploration.

When the Viking landing sites were well photographed, maps of the surroundings could be compiled. I made a grayscale overview based on comparisons between the two camera panoramas, and with reference to sample field maps. A color oil painting of the lander was then done incorporating such work.

More footage of the lightning strike launch! 🌩️ China's Long March 3B rocket was struck by lightning shortly after liftoff from Xichang, yet continued its mission without issue, successfully placing the Tianlian-2 06 communications relay satellite into orbit.

After the 1st context panoramas, the next anticipated image was the first color photo. This arrived and was printed initially too blue, then the next adjusted image came out too reddish. Later work quantified the surface and sky colors in results consistent with the observations of later missions.

I'm a little bit obsessed with this cable on Perseverance. In a landscape painted a million different hues & shades of red, brown & sepia, this is one of the only flashes of such beautiful, pure blue for many thousands of miles... Image Credit: NASA/JPL-Caltech/S Atkinson

The future of lots of easily accessible high-res satellite data seems to have been replaced by lots and lots of utterly inaccessible high-res imagery, controlled by sovereigns. 😔
