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.
The Sunset of September 27th, 2026 was one of the greatest visions the sky has ever opened up and revealed to me. It was a sunset like few I can remember in many years. I knew early on what was likely as a heavy cloud ceiling was opening up far to the West with the underside textures in that part of the cloud ceiling catching the light early on from the distant sunlit clouds.

  Vast connected cloud formations were in turn bathed in the last sunlight which progressively turned from a golden to orange to very red, in as pure a spectral filtering of Sunlight as I can recall seeing. One layer of cloud formations after another caught the light as the rays steadily angled upwards. The most distant yellow gold clouds were dazzling, like incandescent molten gold that defied photography. Lower layers were bathed in the reddest light that contrasted in hue with the more orange colors in the illuminated parts of the broken cloud ceiling above. Wide areas of the field of view were thus illuminated, appearing and fading one after the other like a parade of vast apparitions coming and going.

 The last lit clouds gave up their lurid radiance reluctantly and with a very red final flourish. But the brilliance was still happening, withdrawing beyond the Western horizon as Earth's rotation carried us into the realm of the night. The Sunset lit clouds far away were still in itself illuminating clouds nearby. From their altitude the brilliance and colors along the horizon hundreds of miles away dominate the ambient lighting. This brought an extended 'echo' of the Sunset as every cloud surface facing West shone with that fading lurid glow, like a long slowly fading piano note after a great symphony. 

 I have seen many hundreds of Sunsets and sunrises, but something about this one struck me as almost like a kind of religious experience. Awestruck wonder and numbly bathing in the experience while periodically trying to preserve a visual record.An all sky frame of the Sunset of September 27, 2026. Canon 6D with a fisheye lens. I now shoot most such sequences aimed straight up to show the entire horizon. Unfortunately due to a technical issue this became the first frame of the time lapse sequence, but I did get the extended 'afterglow'.

This morning's Sunrise was interesting not only because of the broad high wispy clouds and the setting Full Moon, there was also a nice display of 'Crepuscular rays', shadows of clouds projected across the sky upon high altitude particles occupying a layer between about 20 and 30 km altitude.
Here are two frames from an all sky Sunrise sequence from Joshua Tree, California. A Canon 6D with a fisheye lens was used to capture the entire sky and surrounding horizon at a rate of 1 frame every 10 seconds.  Notable on this occasion was a strong showing of 'Crepuscular Rays', which are the shadows of distant clouds being cast upon a thin layer of suspended particles roughly 25 km high. At first they appeared over the East as golden and, higher up, pink 'rays' extending the rising morning twilight, then as the Moon was about to set the rays could be briefly seen stretching across the entire sky. The Full Moon setting near the top of the frame as the morning twilight illuminates the high clouds. Stars and a couple planets can be seen in this long exposure photo. Made with a Canon 6D with a fisheye lens from Joshua Tree, California.

On September 16 and 19th, 2026, launches from Vandenberg took place essentially at Sunset, so the actual ascents were unimpressive. However the lighting on the spreading plumes as twilight progresses is always intriguing. The shifting golden, red and luminous blue radiance warrants attention.
This launch took place on September 16, 2026 at Sunset from Joshua tree, California. Not until twilight was under way could the ascent plume be seen as a steadily distorting white diagonal line against the darkening background. As twilight progressed here the play of light and color on the stretching plume commenced.
 As usual the initial illumination of the plume was the very white 'silvery' color of sunlight unfiltered by the atmosphere, which slightly 'yellows' the color of daylight on the ground. As the Sun set from the altitude of the various parts of the plume they became a golden orange then a coral pink, and finally a dim luminous blue. One wonders what the Sunset and twilight up there must look like to result in such colors.
 Photographed with a digital SLR on a tripod. The colors are real but have been brought out of an intrinsically dim subject by long exposures and processing, as an Astrophotographer would reveal the colors and details in very faint celestial objects. This is the later stages of the illumination of the launch plume from September 19, 2026 seen from Joshua Tree, California. Photographed with a digital SLR on a tripod. Parts of the plume are still being illuminated by the last very red bit of the Sun setting from that high altitude. Other portions are lit only by the blue twilight, which quickly fades.   No two such events look the same, unpredictable factors make every such occasion a worthy excuse to have ones camera ready.

I have been shooting time lapse sequences of the twilight sky lately. There seems to be an enhanced presence of high altitude floating material making the 'Purple Light'. Nothing major but enough to notice. The day to day differences in the twilight and cloud shadow presence is worth looking for.
 These are frames cropped from an all sky fisheye time lapse sequence of the Twilight of September 15, 2026 as seen from the vicinity of Joshua Tree, California. I aim the camera straight up and shoot a frame every 10 seconds, often changing the shutter speed to catch up with the dimming light level. It is a procedure that requires practice, and afterward in After Effects the exposures are unified as much as possible in making a motion sequence. I cross fade the resulting frames rather than have them used sequentially as that would be too swift.  The camera used is a Canon 6D using the 8-15 mm lens set to full field of view, nearly 200 degrees. The aperture has to be stopped down a high number, usually F8, to improve the sharpness especially at the edges.

The Sunset of September 7 was an amazing spectacle. As the cloud ceiling of the passing tropical storm dissolved, a window for the last sunlight opened up with fortuitously glorious results. Odd cloud shapes sculpted by winds and moisture had their edges highlighted in crimson radiance.

On September 3, 1976 Viking Lander 2 touched down on the Surface of Mars. When the lander separated from the orbiter the latter began a roll that interrupted lander data for several hours. After a wait the first panoramas arrived, showing not the dune field hoped for but an endless flat rocky plain.
This is a panorama of the Martian landscape photographed by the Viking 2 lander after touching down September 3, 1976. The first landing revealed a gently hilly scene strewn with rocks, with some large enough to wreck the lander if it had ended up on top of one. This prompted a strategy to try and find a smooth site, with a sand dune covered area ideal. The orbiter camera had a 50 meter resolution at best so the broad details and context were as important as the fine details in trying to interpret the nature of the surface along the selected  latitude. 
 The landing site ended up being a level plain strewn with medium to large rocks, with only the tiniest dunes and some little trenches wandering among the rocks. These trenches are analogous to the 'patterned ground' of Tundra and Arctic regions as freeze-thaw cycles alter the ground. One of the footpads landed on a sizable rock and caused the lander to have a pronounced tilt, which has been roughly corrected in this panorama made from color lander photos.

 I initially concentrated on the color of the scenery , then manually recolored the sky and lander to conform to what a better dynamic range camera might have recorded.

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.
My setup for these events has been similar for 40 years. I have a stack of printed Moon images on a clipboard, little lights clipped on tripods and on me, and things arranged so only modest motions are needed for me to observe through the telescope and through the binoculars to get complimentary impressions of the colors. The telescope gives a detailed survey of the color differences in various parts of the Moon, The binoculars give an overall color summary and tend to show more saturated color. One then the other are peered through, and once in a while a photo is made with my still camera nearby kept aimed at the Moon. The photos are modest but provide tonal details in the shadows that supplement the sketches with low res but objective references. 
During this event I am furiously sketching atop the printed Full Moon image sheets, scribbling outlines of perceived color zones and writing color description labels. These labeled 'color by number' summaries are supplemented with sketches of the overall tonal values across the Moon, done on small printed circles provided for this purpose next to the larger printed maps. The time each sketch is made is always written next to it. All during the observing session I have a small portable shortwave radio tuned to WWV, with its eternal ticking off of the seconds and the voice of the Digital Time God. There I am alone in the night, just me and the rare event.

 The nominal shadow colors were seen, with the outermost zone adjacent to the Sunlit area a neutral gray, and smaller concentric zones of subdued golden, then orange surrounding the very dark rusty brick red, 'core'. The entire color range was seen on this occasion. I then reduced my sketches and visual memory into a pictorial summary. It is vital to do the balance of such work immediately afterwards while the visual impression is fresh on ones mind.  The digital paintings were done on top of a digital Full Moon photo I obtained immediately after the Eclipse ended.

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.
This is Lunar Orbiter 1 frame 1102 M, for 'Moderate' resolution. The Lunar Orbiter camera system was a modified reconnaissance  satellite system that used a film camera, developing the B&W film spools and scanning the negatives and converting the opaqueness detected in the precision scanning of 'rows' into data. The signals were reconstructed on Earth making large negatives whose contact prints were impressively large, roughly 20 X 30 inches. 

 While serving the needs of landing site investigations and map makers, the Lunar Orbiter images had issues. They were scanned on board in little strips whose tonal values did not necessarily match between adjacent 'framelet' edges, and there were sometimes repeating variations in the recorded intensity within each scanned line making up a 'framelet' which added more tonal idiosyncrasies. These were only of esthetic concern and the high quality camera system overall performed magnificently, although bad fogging of optics ruined much of Lunar Orbiter 4's systematic Lunar mapping effort and the chemical development process occasionally left defective globs on the negatives. 
 The Lunar Orbiter Image Recovery Project was undertaken to rescue the original telemetry data of those Lunar images. The great majority of the Mission images were successfully recovered using a lovingly reconstructed massive high end tape reader in a leftover MacDonalds building at the fringe of Moffett Field.

  Once the best such image data is available the various stages of accounting for and 'cancelling out' the known departures from what the pristine negative must have looked like can begin in earnest. This attempts to reconstruct something closer to what the original negative from the spacecraft could yield. The famous view that appeared in many magazines and books a the time is here seen in more of a context.  The prominent dark lava filled crater is Tsiolkovsky, among the first farside features to be named. Earth is about to set for the spacecraft.This is a scan of a NASA poster from 1966 giving background to the landmark first photo of Earth and the Moon from Lunar orbit by Lunar Orbiter 1 on August 23, 1966. This photo was widely circulated at the time, in horizontal presentation, and appears in NASA's classic Special Publication SP-168 'Exploring Space With a Camera'.

 Lunar Orbiter was a Lunar mapping project funded in support of the Apollo Moon landing program to enable high quality maps of the Moon to be prepared, particularly of the candidate landing sites. 
 The camera system was modified from a spy satellite design, using dual cameras with wide and narrow angle optics capturing a detail and context image. This reproduction of the narrow angle High Resolution image 1102H shows the 'stripes' caused by uneven scanning of the negative on the spacecraft, which while doing the job of conveying the needed information also bought a distinct 'look' to most photos from that mission. Scanned from my collection.

The Sunset of August 17 2026 featured a modest formation of semi lenticular clouds to the West, however they caught the very reddened last sunlight in a dramatic display. For a few magical minutes the color intensity took my thoughts into realms of numinous wonder.
The Sunset of August 17, 2026 was a fine but small show in the Western sky at Joshua Tree, California. This is a Canon Digital SLR panorama of three frames using a 55-250 zoom lens, pretty much fully zoomed in. This dramatically lit formation was thus only several degrees across along the horizon. The colors are reasonably portrayed, the vividness may have been contributed to by a little smoke somewhere in the hundreds of miles line of sight between those clouds and the Sun. The lower clouds are visibly more reddened in the filtered sunlight than the upper ones with more orange lighting. The Monsoon weather in the High Desert has largely retreated now but a return in several days is likely.

The Monsoon weather pattern noted earlier continues, isolated storms arising and leaving narrow water scoured paths. The Sunset of Saturday, August 15, was a nice show. To the North a grouping of Cumulus towers huddled into a surging peak with a streamlined 'cap' of ice clouds forming at the apex.
This photograph of the Sunset of August 15th, 2025 from Joshua Tree, California shows the most compelling aspect for me of this one, a nice storm far to my North. Cumulus clouds are rising as a mass and catching the subdued coppery orange filtered sunlight, the color possibly influenced by the mixing into the region of smoke from distant wildfires. The highest central mass, its summit shrouded by a cap cloud, rises high enough to reach the yellower less filtered sunlight.

  These are also the kind of clouds I love to paint.

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.
This is a reduced version of the photo released today by the Korea Aerospace Research Institute. Earth is seen from Lunar orbit during the recent Total Solar eclipse. The Moon is barely showing shadows behind the sunlit surfaces, and the shadow of the Moon itself is just at the horizon, or perhaps 'Limb' better suits an orbital view. One very wide shadow shows a fuzzy edge on a distant rise. I added the attribution. This is my version of the Danuri Lunar orbiter photo, with color added.  I combined their Earth photo with a color EPIC-DSCOVR image made at about the same time, rotated a little in 3D to better match the Danuri viewing angle for compositing. The sharpness of the B&W original is preserved with the DSCOVR full Earth photo mostly used for the color values. I also prefer this orientation with the foreground Moon at the bottom.This is the EPIC (Earth Polychromatic Imaging Camera) image from the DSCOVR satellite made at close to the same time as the Danuri image, shown in reduced form but otherwise as released.
 The exposure is naturally for the sunlit Earth and clouds. The Moon shadow's wide peripheral zone of gradual darkening, the 'penumbra' is where the illumination decreases as more of the Sun is eclipsed. At this time the outermost shadow area was near the Great Lakes, from this perspective a circular zone of that radius thus surrounds the progressively underexposed zone around the Moon shadow. If the exposure were adjusted to define the actual umbra, or zone of totality,  the resulting small black dot in the image , about 30 percent the size of the underexposed portion seen here, would be surrounded by the greatly overexposed fully sunlit rest of the world.

The sunset of August 13, 2026 was quite a spectacle. Masses of dissolving monsoon weather admitted the last reddened sunlight through their widening gaps, which went on to illuminate a wide region of fortuitously placed cloud masses.
 This is a panorama of the Sunset of August 13, 2026 made from two frames from a Canon Digital SLR.  This is at the moment of peak illumination, with the days long wind cleaning the atmosphere between the High Desert and the coast allowing deep red Sunlight to pass great distances.This digital SLR photo captures the last fading sunlight withdrawing into the distance as the shadow of Earth inexorably moves beyond the horizon. The faraway lowermost clouds had their lighting persist for some minutes before their lit area withdrew beyond the mountain ridge.

The scattered Monsoon weather pattern noted yesterday continued today, August 11, 2026. The last sunlight gave a nice display as it backlit a disintegrating thunderhead which was still shedding a mass of rain.
This photograph of the Sunset of August 11, 2026 shows the last reddened sunlight playing across the clouds and rain seen from the region of Joshua Tree Park, California. It was obtained with a Canon 6D, as a RAW file which was processed to optimize tonal and color values.

The weather is changing across the High Desert. Isolated thunderstorms are appearing in the afternoons and leaving trails of dampened countryside. In the distance a nice thunderhead rose into the sky some tens of miles away, catching the last rays of the Sun as it's top flattened and spread.
This photo shows a thunderhead NE of Joshua Tree at days end today, August 10 2026. It and some neighboring clouds are catching the last reddened sunlight as moisture passes across the region. The large thunderhead to the left casts a shadow many miles down sun, it may appear as a dark gap in a twilight crepuscular ray display hundreds of miles to the East.  The large thunderhead 'anvil' bathed in the reddened sunlight bringing out the textures of this vast dynamic formation.

A panorama from the dawn of August 9, 2026. The morning twilight is lighting the clouds to the East at left near the overexposed crescent Moon, while at right to the South the light pollution from the Indio and Coachella areas illuminates the cloud undersides and brightens the sky near the horizon.
This is a panoramic mosaic of two frames obtained the Morning of August 9, 2026 from the town of Joshua Tree, California. A Canon 6D was used with the zoom lens at 24 mm, making a panorama roughly 90 degrees across. The spreading of light pollution from the Palm Springs/Indio/Coachella corridor has greatly degraded the former Dark Sky refuge status of Joshua Tree Park. Only in the far Eastern stretches of the park are the skies close to their reputation.  One must now drive to isolated wild places to see the stars as they should be seen.

The Moon at dawn August 9, 2026 from the High Desert.
 This wide angle dawn Digital SLR photo was from Joshua Tree, California. The crescent Moon is behind the broken clouds, with the twilight colors just starting to appear as dawn advances. A faint indication of the Zodiacal Light appears as a wide vague glow connecting the Moon with the brightest part of the dawn. Orion, now rising as darkness fades, is partly masked by the clouds on the right.This photo of the Moon at dawn on August 9, 2026 overexposed the sunlit Moon but nicely shows the portion lit by light reflected from Earth. The foreground clouds obscured the Moon much of the time but occasionally gave a peek at the crescent. The Moon is drawing closer to the Sun by the hour. it's rare crossing of apparent paths with the Sun results in the upcoming Total Eclipse.

A Viking art related footnote... Author and flying saucer photo fabricator Billy Meier, in a video represented as showing photos from his space voyage, used stuff from books as things he claimed to see on a 'space trip'. One of these was a painting of the Viking orbiter that I did in 1975 for NASA!
A bizarre tale was brought to my attention not long ago about a European flying saucer evangelist who claimed he had been taken aboard one and transported through space and time. Normally I wouldn't have found such a claim worthy of notice but while looking through a referenced 'extraordinary claim' video I noticed that Billy Meier shamelessly used various images from NASA in his presentation of still images he claimed to take on his 'space trip'. One of these was a painting of the Viking orbiter that I did in 1975 for NASA.  In his video presentation he shows photos made off a TV monitor of images from books taken with a camcorder. 
 I am amused that one of my works was ID'd as an alien spacecraft. It is astonishing that he thought no one would call out such a blatantly fabricated presentation. In the early 1970s that fellow faked a bunch of photos of flying saucers apparently using models etc. against European countryside, which were published in a big coffee table book  I remember seeing in bookstores in the early 70s 'UFO...Contact from the Pleiades'.
 I remember being amused at the amateur quality of the flying saucer photos in that book. They were defocused enough to cover some sins of fabrication like strings, or were consistent with thrown models. It would be informative to examine the original negatives of his camera photos to see the ratio of used vs discarded photos of thrown models. The sheer quantity of his claimed flying saucer photos is suspicious, as if something extraordinary was going out of its way to be repeatedly photographed by him.
 Here is the video presentation if you want to suffer through it. It's a poor quality video of Billy Meier flipping through a photo album of photo prints apparently photographed from a TV screen showing camcorder views of varied space images, mainly from NASA releases. At 0:47 my Viking orbiter art appears. At 5:01 a Pteranodon painting by Zdenek Burian is unmistakable.

The Sunset of August 7, 2026 featured only a few fairly distant clouds low on the Western horizon, but with a 55-250 mm lens I could zoom in on an intriguing adornment, an 'Sun Pillar' forming a fuzzy vertical bar of light as the reddening sunlight was reflected by roughly aligned ice crystals.
This is a panorama made from two digital SLR  frames obtained of a cloud as it was being lit from underneath by the last rays of the Sun,  hidden from the ground but still shining on the fairly distant and high altitude cloud. A bright vertical glow at the right is a Sun Pillar', which is the Sun bring reflected by fairly uniformly aligned ice crystals. This Pillar assumes the color of the light source.   This series of photos of the Sun Pillar accompanying the Sunset of August 7, 2026 shows the lighting changing in direction and color on the clouds. The 'Sun Pillar' persisted until the last rays left the clouds, the color becoming deeper red as that light passed through greater distances of atmosphere as seen from there.

The twilight of July 20 was a pleasant surprise, not just because of the dramatic clearing of clouds that had shortly before made a nice Sunset, but because of the fine display of crepuscular rays spread across the pink/golden twilight.
The clouds quickly cleared the evening of July 20, revealing a magnificent spread of crepuscular rays looming from behind the distant clouds. There is a thin layer of aerosols/dust etc at roughly 25 km (16 miles ) altitude which when illuminated by the last very reddened rays of theSun at that altitude forms the balance of our twilight glow. From 25 km high the horizon is 565 km (350 miles) away with higher clouds at least a hundred km farther extending from beyond that horizon. As they block the disk of the setting Sun at that altitude they cast shadows that can approach 500 miles in length.
The greatly oblique shadows of such clouds are seen here, letting more of the 'nominal' darker sky blue color show more. Apparently there is an elevated presence of light catching material in the Stratosphere.

  Some enhancing of the contrast of the rays has been done, often visually subtle contrasts are more easily seen with the eye than in a raw photo.

I finally got around to processing some sky photos made over the last few weeks. It's been 100 F (38 C) and higher every day for what seems like a couple weeks and the hot wind is relentless. Occasionally some clouds appear, and before they evaporate nice sunrise/set displays happen roughly weekly.
On July 17 2026 there was a very nice sunset, with openings in the 'curdled' looking cloud ceiling earlier allowing the Sun itself to be seen setting, Then its rays illuminated the air as they rose, fading soon just as they began touching the cloud ceiling. 

Digital SLR photoOn July 20 2026 the weather was fairly dynamic, with lightning storms perhaps 100 miles (160) km away. This rather distant towering display was glimpsed through gaps in nearby clouds as the last sunlight illuminated it. Digital SLR photo.On July 25, 2026 there were sparse but intriguing clouds trying to become Lenticular formations but were apparently dissolving as fast as they were appearing. In the wind driven clean air the Sunset colors were particularly intense, with the undersides of these shapes illuminated by sunlight traveling through hundreds of miles of clean atmosphere, giving the remaining light a generous helping of the red end of the spectrum. I would have liked to have made a time lapse of this but the blustery winds would cause jitter between frames.

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 oil painting portrays the Viking 1 landing on Mars, which appeared in countless publications. The story of this work is relayed in an earlier post and is shown here for comparison with the new portrayal of this very view, showing the event as it would have appeared. 
This 1975 anticipatory painting was done with oils on a gesso smoothed 16 X 20 canvas panel, using traditional art methods including a tracing paper guide featured earlier. 
 This work shows in retrospect my ideal of the 'spirit of space art', showing something of a summary of what is known of the subject while conveying what it is about the subject's known or theorized attributes that I find visually compelling. The new digital painting updates that visual impression with one based on our current knowledge. The new digital work was also done at the same size as this one was for possible printing purposes, 16 by 20 inches at 300 DPI.
 #Sciart   In 1976 the pair of Viking spacecraft orbiter/lander combos were sent to Mars. Before Viking, Mars was still largely a place of our imaginations, an unknown that we wrote stories about then studied from Earth and space. The dominance of cratered terrain on the portions of Mars photographed by Mariners 4, 6 and 7 gave an initially Lunar impression of that world, which changed during the development of the Viking lander after Mariner 9 revealed the planet.
 The first landing was aimed for a flat flood plain, judged as a decent place to search for life. The landing date was July 4, however the intended site appeared too rough for comfort in the high quality orbiter photos, causing the landing to wisely be delayed. A smoother site further 'down stream' was found using photo and radar data.
The landing proceeded quite nominally, a magnificent achievement that apparently accounted for what it had to and made it the first time.

The first photo from the surface was a look at a footpad to see how solid the 'footing' appeared. Then a moderate resolution panorama of the surroundings was obtained, first showing the rocks, hills, dunes-and bright sky. The latter was my biggest surprise as a space artist. 

The adjustments to the color balance of the later photos were gradually narrowed down. The ubiquitous dust is planet wide, suspended in the air and coloring the sky a luminous tan ochre. 

This digital painting shows the view a meter above the surface seeing the lander briefly kicking up dust less than a second before touchdown with the footpads 1.4 meters high. The landing rockets were designed with many nozzles to disturb the surroundings as little as possible. The nearby disturbed dust resembles in color that of the sky. We are 6 meters away from the center of the lander. field of view is 60 degrees, we are looking Northwest with the Sun and Earth off the frame to the left.

This is a digital art update of the pre mission oil painting I did for NASA HQ 1n 1975.

The Moonrise of July 27th as the last rays of the Sun left the High Desert.
This photograph was made as the day ended on July 27, 2026. As the last reddened rays of sunlight shine on the far mountains, the shadows of the mountains to the West behind us are already darkening the foreground ridges. The exposure is tricky in photos like this due to the wide brightness range of the scene. After selecting an exposure that best recorded the overall brightness range, I first in Photoshop made a 'matte' of the border between the brighter sky and the much dimmer jagged mountains bu careful contrast stretching and painting, ending up with the sky and land separately selectable. I then processed the RAW image file twice to optimize the exposures in both and combined the two results.

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.
This vertical view of the Viking 1 landing site is based on the surface panoramas, extrapolated from the cameras views, seeking to place the featured in reasonably proper relative distances from the lander. Such work was of course drafted and executed by hand. 

After the Viking mission two large format NASA Special Publications were especially valuable in later efforts to portray the Viking landing sites in Perspective. First,  of course, was NASA SP-425 The Martian Landscape'  with beautiful large reproductions of earlier Viking photos, and NASA CR-3568 'The Viking Lander Atlas of Mars' which displayed the derived locations of landscape features in 3D space, plotted in contour lines defined by the perspective  of the two cameras. 
 This is a low resolution view of an artwork done in an odd art medium, scratchboard with a gray dot screen printed on it as a basis for making white or inked marks. Several sheets of this were given to me in the 70s by Chesley Bonestell, encouraging me to play with them. He said they were old, so that could mean WW II or so. I used all but one for such Planetary work.  I did maps with them of the sites of Vikings 1 & 2, Venera 9, and Venera 10. All those were published in Sky & Telescope magazine, and in their volume 'The New Solar System', which used my art through out the book.  I also made an overview of where they thought Viking 1 was, which turned out to be incorrect.

 An unfinished one of the Lunar Orientale basin awaits completion, at the time I started it the Western portions of that basin were still poorly photographed and my drawing was going to be an improvement in the available imagery.  Now it is quite well known so there is less incentive to finish it.
 #Sciart Viking 1 on Mars. This oil on illustration board painting incorporated my efforts to plot the lander surroundings in perspective, and of course knowledge of the final actual lander appearance. The nearest footpad is entirely buried in the powdery dust, a sight which would have certainly been alarming if that had happened to the footpad seen in the first photo!  The large rock in the right foreground was nicknamed 'Big Joe'. Just to the right of the lander along the horizon is the upraised rim of a distant impact crater. 

  The overall color of the scenery reflects mostly influence from initial contemporary sources. National Geographic published a Viking article which featured the kind of independent first class photo work they used to be known for in the early space age. Their color chart driven version of the Martian scenery tended toward the brick red, reasonably approximating the hues as if lit by a noon time Sun in a Terrestrial sky. This painting was initially done in a similar color balance to what they mostly used, then later I learned of the ambient sky etc contributions and overpainted the scene with an orange tan layer. The result color wise is something in between what it was and what it should be, but the scenery remains valid.   The Martian sky was based on Viking camera images, whose truncated brightness near the top of the frame complicated portraying the actual sky brightness range.

A few more Viking 1 Mars surface images. Vikings 1 & 2 yielded a variety and duration of observations that gave the first 'Ground Truth' about this intriguing neighbor world's surface and atmosphere. It's early digital camera design worked well with the brightness range of the surface details.
Late in the afternoon of Martian day 651, on May 20, 1978, the lengthening shadows of the larger rocks were photographed by Viking 1. 

A few tries were done at obtaining color photos with the higher resolution settings of the camera. A raised rim of a 500 meter wide impact crater about 2.5 km away can be seen at the horizon, looking much like Arizona's Meteor Crater as one approaches it. The image processing attempts to show something of the actual brightness and colors of the scene and sky.  The Martian surface is darker than the impression one would have from most of the photos, which are understandably optimized in exposure to bring out surface details. Three tries at using the color and grayscale chart to recover the colors of the scenery. The grayscale ended up being pivotal in obtaining some sense of color balance. I tried incorporating the IR data by using it to modify the blue to try to cancel out the leak of Infra Red through the blue filter, but I was unable to obtain coherent results. So I gave up on making the blue chip blue, which notoriously photographed as purple with that camera anyway, and relied on the gray scale to establish some color anchor point. I am not an engineer trying to account for all the camera quirks, I approach this like I would when photographing my artwork. I have a gray scale and color chart in the frame for reference and adjustments. 
  Basically, using the 'curves' tool in Photoshop to establish a gray point is the key. The initial result is usually ludicrously garish so I then reduce the saturation to best show the red and green chips as as well as the overall scenery, in this case seen 'over the shoulder' of the lander. Of course there is judgement involved in seeking to show what I think the camera is seeing.  An early space image processing I did over 20 years ago, of the celebrated Viking 1 Sunset picture. I took the grayscale files and hand blended the rather coarse steps in the brightness contours recorded by that limited grayscale camera system in the twilight. This, along with retouching of brightness variations in the dark foreground spacecraft parts etc. as they were scanned, was done to show this amazing image to its best advantage.  I remember being captivated when I first saw a contrasty initial version of this image in a Viking newsletter.  

 Although Viking is a rewarding data set to explore, the monumental and sterling work of Olivier Goursac makes me think twice before thinking I have any new contribution to what has been done. 

 I wish to acknowledge the useful and enduring Viking image browser set up by Holger Isenberg, with all the lander images available to download and play with.

Tonight, July 22 marks the 6th anniversary of a mystery in the sky that I was apparently one of the very few to notice. I saw and took photos of a fuzzy compact 'glow' about the apparent size of the Moon. It rose reddened at first from local atmospheric effects, then slowly moved North and faded.
A typical photo of this 'mystery glow' that steadily and slowly drifted among the background stars. 
 I was about to conclude my fisheye time lapse of the comet appearing in the evening twilight then setting. I used my large binoculars to scan the sky along the horizon. While peering toward the Southeast I noticed a distinct fuzzy patch of light, like a poorly resolved globular star cluster. I stared at it with the binocs and determined it wasn't quickly moving or dissipating. I then retrieved the tripod mounted camera which was off the road a little among things you didn't want to brush against or step on, including a tarantula the size of my hand. I changed lenses from my fisheye to my 'fast' lens and proceeded to photograph it. Over time it moved among the stars, slowly dimming. 
 It was probably the Tianwen-1 Mars orbiter launch vehicle upper stage venting propellent, a mission launched within hours of this observation. Here are my combined  images of the mysterious 'fuzzball' I saw and photographed the night of July 22. The timings are close to the beginnings of the exposures. I approximately matched the exposures in the different frames to help show the brightness changes. The sky grid with 2000 coordinates was also sketched in to aid in showing the motion of the fuzzball over time against the stars. The exposures vary, 15 to 20 seconds at F:1.6 ISO 1600 for the earlier images, the last few were 15 seconds F 2.8, ISO 3200. All used the Canon 50mm F 1.4 lens. A frame from the July 23, 2020 time lapse of Comet Neowise in the dark skies that I travelled to Sheephole Valley Wilderness to obtain. There's still a lot of glow from the LA region and Las Vegas shines in the distance, but most of the sky is nice and dark. At the end of this sequence the 'fuzzball' can be seen rising but as I tilted the camera the other direction it  appeared in the frame well above the horizon. As I type this i was just finishing this sequence.

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.
The first color photograph from the surface of Mars arrived about 24 hours after the landing as grayscale 'scans' of the landscape with the red, green and blue filters. The 3 component images came in with the red brightest and the blue the dimmest, which when initially combined appeared so red that they were skeptical of the colors. The initial hurried release of that image occurred 8 hours after the data was received. The intent was to make the sky a neutral gray, but during the photograph's mass printing from a master negative the color balance of that first batch somehow drifted toward the blue, giving an initial 'Earth like' impression to the scene and sky.

 This initial release (upper left) appeared on TV news and the covers and color spreads of many magazines.

 Later (lower left) A slightly 'over corrected' version emphasizing the reddish ambience was released. 

  Later work with the digital files shows an approximation of the scene as if lit by noon sunlight with minimal ambient contribution (upper right) and an approximation of the scene with the ambient lighting from the bright butterscotch colored sky factored in (lower right). This is the closest to what eventual human explorers could see and photograph there with their own cameras.      

The initial prints were distributed, I was fortunate to get one which I still have, and a large color print was shown on an easel, which people were gathered at transfixed, staring at this first 'window' into Mars.  High end color CRT monitors with that image were scattered across the press area. They were adjusted better than the prints, using separate RGB adjustments in the back. I got close to one monitor and someone warned me not to touch it, that someone had just gotten yelled at by Jim Martin for playing with the colors! I later learned more about this story, which contributed to a conspiracy narrative which the early internet conveyed that NASA was trying to hide the true Earthlike appearance of Mars.

Here is one more pre mission Viking related painting, the 9 X 36 foot oil painting on canvas I executed over a couple weeks or so at JPL. This was, as before, a summary of my understanding and assumptions about the landing site. I deliberately painted the scene with an eye level horizon. #Sciart
When the painting was (nearly) done I was photographed with Viking mission project head Jim Martin. I gave him and some mission bigwigs a slide show of my art in a darkened office, when I showed the painting of Viking on the surface that I had done for Jack McCauley he laughingly expressed concern about all the rocks I had portrayed. 

  Last I heard years ago the work was rolled up and stored somewhere, but I don't know if it has survived.

The left portion of the mural as it should be seen, well lit and color balanced. Some of the original 'rolled' texture of the canvas can be seen on the lower left, alas it was not properly glued to a rigid surface but simply stapled on, although competently so. 
The usually not seen lower right of the mural. Photographed as a test of the functioning panoramic camera on the Science Test Lander, which also had a functioning sampler arm to rehearse its movements in a sand box with rocks carved in styrofoam placed before it matching those in the real scene.  Holger Isenberg rescued this and other Viking test images from obscurity and shared them with me. A unique photo of my backdrop painting by the replica camera on the Science Test Lander. This is from a color print given me later on, I don't know if the digital data from this camera test has survived.

Mars as imagined just before the landing. This painting, one of a trio done for NASA HQ, ended up being used for the JPL landing press badge. What a thing that was to see when I arrived and signed in!
 This painting was, as is much of Astronomical/Space art, a summary of what was known of the subject as well as what about it I found visually appealing. Low gravel bar ridges and dunes dominate the scene, based on the original landing site chosen in Chryse Planita. A suggestion of sedimentary layering is shown in the lower right foreground knoll. The sky was portrayed as blue, making the assumption that it would be like a Stratospheric altitude Earthly sky. Earth is the daylight star just to the left of the lander. The aeroshell on it's parachute from which the lander was dropped drifts downwind in the distance to the left.
 The reference materials I had available then were a step or two short of how the lander actually appeared, with the biggest difference being the lack of the rubbery fabric covers over the propellent tanks. 

  #SciartThe press badge issued to media at the JPL press area. The last appearance of the Mars of old based on imagination and educated guesswork. This badge is now among my treasured trophies.

And of course in addition to the Viking 1 landing there is also the highlight of all space related anniversaries today, that of the landing of Apollo 11 on the Moon. The memory of this event is a highlight of of many people in my age group. The Moon became part of human affairs then, and will again.
This is a panorama made of still frames from the video from the surface during their EVA. Earlier camera angles were combined with a good frame showing the Astronauts from when after the camera pointing was finalized.   This panorama is from the first color film photos made out the windows after landing but before their EVA. The bright area at the top of the Lunar Module shadow is the strongly back scattered character of the ground, driven largely by the glass globule content of the surface layer where the shadows of the heads of the Astronauts would be. It's like the signs with glass bead carrying paint that reflect ones headlights back to you.

I will show my Viking related art in a slow trickle over the next few days, as there is a fair amount of it and a new one is coming. This is a pre mission oil painting done for then USGS Astrogeology branch chief Jack McCauley, based on his anticipations of how the landing site could appear.
This mid 70s oil painting attempts to summarize a leading Astrogeologist's idea of what the surface of Mars in the general intended landing zone on a wide flood plain might look like. Jack McCauley familiarized me with his work in the coastal deserts of Peru and photos of the Dry Valleys of Antarctica, places where likely Mars like surface features could most be seen on Earth. Streamlined 'gravel bars' preserve an ancient wash, with blowing dust filling some of the deeper winding channels. Small impact craters continued to form since the climate dried up. The dark sky suggests the anticipated visual appearance at the known atmospheric density, of course not accounting tor the eternal dust pall that actually ended up brightening the daytime sky. The lander was based on photos of models available at the time.

I'll never forget that long night 50 years ago now. After a tense wait suddenly a voice on the speaker announced 'Touchdown-we have touchdown!' and the press area erupted in cheers and applause. All night people took in the moment, with celebrities being interviewed in front of the lander mockup.
The long vigil in the Press auditorium, with journalists from all over the world gathered there.  I managed to get press credentials through Sky and Telescope, which I had just begin a long fruitful relationship with as the first of my covers for them portrayed this mission.  As the anticipated landing time approached things grew quietly tense, with the slightest ambience of typing, scooting chairs and scribbling on paper. Descent related data was being announced, altitudes, etc then at 5:12 AM suddenly 'Touchdown, we have touchdown!' was announced by the same voice, bringing extended clapping and cheering. 

  Later in the night the gathered luminaries in space, and a generous sprinkling of celebrities, Chatted, expressed their happiness and helped make the occasion memorable. In those days the JPL space mission arrivals were attaining the status of 'Gatherings of the Tribes' as space writers, journalists in film and TV media and even space artists worked to be there through at times creatively concocted affiliations with space related outlets and people. This 'Tribal Gathering' status perhaps peaked during the Voyager missions under JPL Public Affairs head  Frank Bristow.

The first glimpse of the Martian surface was long anticipated. Bonestell's art dominated ideas of what Mars was like, basically the desert Southwest with most air absent. The idea of a dark blue sky on Mars persisted in space art until that morning. Here are those first looks at the Martian surface.
Top: the first view of the Martian surface, which appeared in slow steps left to right as the data came in. They wanted first thing to know if the lander was on solid ground and not too buried, sinking etc. The imaging sequence started 25 seconds after landing and continued for 5 minutes as the camera scanned a vertical line at a time moving to the right to scan the next. Having the orbiter relay the data took another 20 minutes. At left a brightening in the image can be seen that intensifies then fades, followed by a darkening that soon goes away. That represents a kind of record of the dust kicked up by the landing that brightened the field of view, then the shadow of the dust cloud briefly darkened the scene. The prominent angular rock near upper center is about 10 cm (4 inches) across. This first peek reassured everyone that the lander was on solid ground. A little dirt kicked up by the lander rockets can be seen pooled in the footpad.  

 Bottom: 6 minutes after landing  the second photo was obtained, a lower resolution 300 degree wide panorama of the surroundings taking in the scene in 9 minutes. At once the character of the scenery showed its distinctive nature, rocky and lightly even ground with small drifts and patches of lighter fine dust. The presence of dust in the atmosphere brought a brightness to it that was not anticipated, as an artist that was the major revelation I felt when looking over the scene. The atmospheric density was known to be like Earth's at 40 kilometers or 130,000 feet, so any noticeable blue sky brightness should only be evident near the horizon. In reality, the eternal presence of wind blown dust makes the sky a luminous version of the color of the ubiquitous surface dust, especially in the quarter of the sky near the Sun.

  Suddenly rendered dated were all those paintings by Bonestell, Pesek and others which were done between the times of the Mariner missions and the Viking landings, showing interpretations of known features but … I had my Polaroid SX-70 camera with me when just after the landing I was suddenly escorted from the press area into into the imaging team room, hastily badged and plopped in front of some of the many monitors in the area which steadily unveiled the first two looks at the Martian surface. No journalists were there dur to JPL PR department policy, but I got a few photos and a sound recording of the excited chatter of the geologists seeing Mars revealed. "Look at the exposure on that S_O_B" I remember hearing when the prominent rock appeared. Then the President called in his congratulations which went over the PA system. A highlight of my life, onr of several instances where I was in the Coolest Place in the world at that moment. My carefully obtained Polaroid from a monitor in the Imaging team area, at the conclusion of the introductory scanning of the first photo obtained of the surface of Mars.

Something I noticed while painting my Viking lander backdrop mural at JPL in 1975. The first of a number of Viking related posts on this 50th anniversary of that unique historic occasion.
This photo on color slide film was made in i975 at Jet Propulsion Laboratory, in some out of the way corner of the building where I was painting a large mural of the Martian surface. The uniqueness of the labeling, including 'This item is designed to go to the planet mars' was irrestaible to capture.

Smoke influenced our skies in the High Desert a week ago. Here is the Moon at dawn July 12, reddened by a smoky atmosphere and partly veiled by patchy clouds.
This photograph shows the crescent Moon at the break of dawn July 12 2026, with the Sun illuminating a thin portion while the entire Earth facing side is also dimly lit by reflected light from the sunlit Earth. Patchy clouds are in front of the Moon and are diffusing the light of the sunlit portion. The overall colors are heavily filtered by smoke from regional fires.

For Asteroid day, my cover for the 1985 book by Donald Goldsmith, 'Nemisis-The Death Star and other Theories of Mass Extinction'. A rare (for me) black and white painting.
This is a B&W acrylic air and hand brush painting depicting the impact that caused the end of the Age of Dinosaurs. Tyrannosaurs are startled by the last event they will see.  A disruption of the Oort cloud by a theoretical distant Solar companion star was pondered as a factor in this and possibly other mass extinctions. This is the reason for seeing multiple comets in the sky.

Last night's launch from Vandenberg was a little early for optimal lighting at liftoff, but the plume remained illuminated for a while as twilight deepened, stretching and winding about as high altitude winds tugged at it in various directions at different altitudes.
This photo was made with a Canon 6D on a tripod with 2.5 sec exposure, stretched in brightness and sharpened to bring out the variety of textures in the dispersing plume.  This one was relatively subtle in its colors, with blues, white and only a small red region later at the lower right. These launches and their aftermath are remarkable sights and these images are obtained to capture them for their striking novelty, with no implied endorsement of what the payloads are or who is behind them.

Six photos with the same portion of the sky in common, showing brilliant Venus and bright Jupiter changing position in relation to the background stars between June 6th and 11th. The photos show differences in weather and atmospheric clarity between the dates.
This series of photos, made with a tripod mounted Canon 6D with the same 50mm lens, records the presence and movements of dazzling Venus and brilliant Jupiter as they passed a few degrees from each other between June 6 and 11 2026.  Over the last week the brilliant pair, acting as the 'Evening Stars', crossed apparent paths in our twilight skies. At their closest on June 9 they closed to three full Moon widths apart from each other. I made it a point to capture this conjunction, not the closest between planets by any means, but a splendid sight as the two brightest planets drew close then apart over several days. Care is taken to have the same star background in all the photos, better showing the movements of the planets, two orbiting bodies seen from another orbiting body. Differences in weather, atmospheric clarity and time of exposures give each evenings photos a distinct 'look'. The last, the 11th, had clouds diffusing the light of the planets in varying and interesting ways. I would have made a time lapse sequence but the wind was near gale force and impossible to keep everything consistently still even when holding the tripod top.   The evening of June 8th as the planets loomed close together in the evening twilight skies. Elusive Mercury also shone brightly near the horizon at the lower right. In the High Desert Sunsets have long 'afterglows', and as the last blue of twilight retreats, the residual sunset illumination fades and the city lights between San Bernardino and Los Angeles supply their own ubiquitous lighting on the clouds. But even in this direction, with the cumulative Western light pollution, the stars can still be captured.June 9 was the time of closest approach, when dazzling Venus and brilliant Jupiter were about 1.7 degrees apart in the sky, about three full Moon widths. When looking at the conjunction I mentally 'added' an extra Moon width outside the pair to appreciate how large Earth would look from the surface of the Moon. To the right of the planetary conjunction, Pollux and Castor are the highlighting heads of the twins of the constellation Gemini, whose nearly upright 'stick figures' are suggested by the loosely vertical groupings of stars extending below the bright stars.
Mercury is not often seen but it now looms low in the West as darkness allows its visibility. Mercury made a kind of 'long triangle' with Pollux and Castor, near the horizon directly below the bright star pair.

I made this animation showing a small impact on the Moon, the resulting crater and the effects of the debris cloud passing Earth. Done originally in response to the now ruled out 2032 impact on the Moon of the small asteroid 2024YR 4, the possibility of Lunar impacts remain. vimeo.com/1197048261
These are frames from an animation I made of an impact on the Moon showing stages in the formation of a small impact crater. This was done with modeling terrain with grayscale hand drawn height maps, 3D rendering and After Effects. 


 While this animation was composed around the possibility of a predicted Lunar impact at about 15:19 UT December 22, 2032, the possibility of a small stray asteroid hitting the Moon is always there. Flashes of modest impacts are frequently recorded on the night portion of the Moon with video camera equipped telescopes. Astronauts during the Artemis II mission reported seeing flashes across the night side of the Moon which were attributed to small impacts. 

 The animation these frames are from portrays the formation of a new 1.5 km diameter crater over an actual location on the Moon. The spreading inverted conical debris plume is based on experiments in vacuum chambers shooting projectiles into carefully prepared sand boxes. The lowermost portions of the uneven ejecta plume fall back on the surface and make the 'rays' of crushed rock which radiate like painted starbursts from the freshest craters. The outermost portions of the plume reach escape velocity, and some of that spreading hollow conical 'spray' can reach Earth. 

 A cloud of even fine debris passing across Earth could cause disruption of numerous satellites, a possibility that has multiplied with the proliferation of constellations of thousands of satellites. An explosive event in one could cause nearby satellites especially in their initial deployment stages to in turn be struck with a kind of 'kinetic chain reaction' taking place, the so called 'Kessler Effect' increasingly feared by those knowledgable about space matters since the idea was circulated in 1978. Along with the brief meteor cascade, numerous uncontrolled satellite re entries could be expected, one of which concludes the animation.

Tonight, May 30 2026, the Full Moon rose as a glowing orange yellow globe behind the craggy mountains, giving its soft light to the scenery as it climbed while the Western twilight faded away.
 This is a photograph of the Full Moon rising as twilight fell on Joshua Tree, California. This is actually an elaborate composite of three photos made within a few minutes pf each other, with detail from two others made to conform to the preferred one of the Moon symmetrically placed among the silhouetting rocks. This 'reference photo' was exposed to show the Lunar tonal details. One longer exposure was used to add detail to the mountain textures, another recorded the tonal values in the sky surrounding the Moon as soon as it had cleared the mountains, including the brighter area near the Moon. These were manually fitted to and combined with the preferred exposure using Photoshop layers.

This is a cropped portion of a frame from a fisheye (hemispheric) animated sequence. I made a model of the spacecraft, and elaborated on the environment setups I had done earlier to create digital still portrayals of the mission for publication.  I had gone to all that trouble so I figured 'why not'. 
 The stars and spacecraft orientation are from the real time telemetry based NASA simulations shown in their mission coverage, which had the spacecraft orientation but on their in live app screwed up the stars, with the celestial pole wildly out of place. NASA's 'Eyes' lacked the detailed spacecraft orientation, which the related department of NASA apparently declined to share with them, however 'Eyes' got the stars right. Together those resources allowed a decent reconstruction of the photogenic moments of the mission in wider views. The referenced animation lacks the spacecraft, concentrating on the Earth itself. I was trying with that animation to imitate what a low light color video camera might have captured.

Last night another launch plume was visible low on the Western horizon from a Vandenberg launch. The launch itself was near Sunset from Joshua Tree, so I didn't bother to look. I anticipated the plume catching the light later, and indeed as twilight receded there it was, spreading and colorful.
This photograph was made from Joshua Tree, California of the remnant plume from launch from Vandenberg last night, may 19 2026. Although the launch itself was not worth trying to see, I anticipated the plume persisting long enough to still be illuminated bu the Sun after twilight in my location. Sure enough, as the sky darkened the faint whitish wisps

The raw photos release from Artemis II have provided a great opportunity to explore the images in their variety and variations. As a Solar eclipse was photographed, the radiating coronal streamers extended from the hidden Sun. I brought out their details by sharpening combined different exposures.
 This is a combination of multiple exposures of the Solar corona and inner Zodiacal Light seen extending from behind the moon as Artemis II was entering the Moon's shadow. Sharpening was applied to bring out the radiating fine detail. This kind of detail is routinely photographed all around the Moon during a Total Solar eclipse seen from the ground, but this is the first dedicated observation of this kind from near the Moon using cameras capable of capturing the sight.  In a terrestrial eclipse the Moon barely covers the Sun, here the Moon is roughly 25 times the apparent diameter of the Sun.  As the eclipse as seen by Artemis II ended, a different portion of the Solar corona was seen extending from beyond the edge, or 'limb' of the Moon. This occasion was a kind of 'bloated' version of the kind of Total Solar eclipses we can see from the Earths surface. Through a cosmic co incidence, The Moon barely covers the Sun from Earth, sometimes not quite covering the entire disk and sometimes large enough to provide longer Totalities. In this spaceflight related instance the Moon is roughly 17 degrees across in their view rather than the barely Sun covering half degree we get on the ground. The Moons edge is visible across the entire frame as the wider diffused outer corona and the inner Zodiacal Light extend across a wide area of the sky.
 Multiple exposures were carefully combined and sharpened to bring out subtle low contrast details in the Solar corona.

Tonight's rocket launch took place against a bright early twilight and was thus washed out. However, as usual, the sunlight played across the stretching and twisting remaining vapor column, which is initially a silvery white. The setting Sun's last light on the vapor gives it a striking red color.
This is a photograph made of the residual plume from the launch of April 29, 2026 from Vandenberg. When local Sunset in Joshua Tree, California took place a half hour previously, the fading sunlight colored some cirrus clouds beyond the frame a red/pink color, and the Western sky was a bright amber pink at the time of the launch. This made the launch itself marginal to observe, although people far to the East into Arizona etc would have seen it against a darker later twilight.

 The remaining plume, however persists and is itself worthy of observation over time. Beginning as a gracefully arcing path, it quickly shows the effects of the high altitude winds blowing in different directions at different altitudes. It at first becomes a zigzagging path then is steadily pulled into stretched and knotted looking shapes. From the great altitudes of the plume along its length one would see the Sun at first above the horizon, casting on the vapor a harsh almost blueish white light not yet filtered by the atmosphere as we get it on the ground. The Sun setting behind the thousand mile distant horizon is highly reddened in its last traces, with whatever color predominating in the twilight visible from that altitude then determining the colors of the fading illumination, a process that happens at later times in higher altitudes and differs with the whims of local conditions. Thus from the illumination colors some sense of the three dimensional structure of the illuminated distended mass can be had over time. As I typed this I had a sudden impression of a drawing of a Road Runner bird, which I occasionally see here.

An April 1980 oil painting, Possibly the first showing the impact hypothesis of the end of the Age of Dinosaurs. Then no one knew where the crater was so I arbitrarily put it in distant Mongolia. A group of Saurornithoides are having their feast interrupted by a huge nearby impact.
This is an oil painting on illustration board portraying the impact that ended the Age of Dinosaurs. This 1980 work may well be the first painted  portrayal of this hypothesis, although it took another decade for its location to be determined. As in space art, Dinosaur art over the decades preserves something of the knowledge and especially the limitations of related knowledge at the time it was created. My choice of Mongolia as the impact site reflected our lack of a determined impact location then. The predatory Dinosaur Saurornithoides shows the 'pre feathers' ideas of what such animals were like. They certainly look 'naked' after decades of seeing paintings of feather covered smaller Dinosaurs, but ideas changed and this painting freezes in time the state of related knowledge and ideas of the time in which it was created.

Tonight's launch from Vandenberg was late enough that it reached the sunlight only relatively late in its ascent. When it did it rose through first the red of the last filtered sunlight, then climbed to the daylight with a striking pale blue radiance coloring the upper portion of the plume.
 This is a photograph of the launch from Vandenberg the evening of April 22, 2026. It was obtained from Joshua Tree, California. The rocket plume is climbing into the sunlight, with the lower and rear portion illuminated red from the dolor of the fading sunlight one would see from that location. Higher up the sun shines on the spreading plume, strikingly blueish white. This is partly due to the character of unfiltered sunlight which appears a little 'blueish' compared to what reaches the ground. It is also driven by the way the plume particles, mostly water vapor, scatters light which particularly in the general direction of the Sun emphasizes the blue wavelengths. During the entire climb visible from Joshua Tree the bottom of the plume remained reddish, as the Sun was apparently being extinguished by the atmosphere as seen from it's entire lower portions.

On Earth Day, our home world seen from behind the Moon photographed 53 years apart with hand held cameras. Top: A crescent Earth rising from behind the Moon from Artemis II. Bottom: The gibbous Earth setting behind the Moon from Apollo 17. The rugged Lunar horizon cuts off Earth in both views.
 In both of these views, photographed with hand held cameras, the night side of the Moon is hiding part of the blue and white Earth. Mountains and irregularities on the Moon are silhouetted against the bright Earth, which from the vicinity of the Moon appears four times as large as the Moon appears in our skies. 
 The upper recent view was obtained with a digital camera during the Artemis II, the bottom one with a medium format film camera during the Apollo 17 mission.
