Discover online has an article today about some of the best in amateur space imaging. Many of which have been featured here on Wanderingspace before like Gordan Ugarkovic, Emily Lakdawalla and Bjorn Jonsson to name a few. The last item from Bill Dunford of Riding With Robots is an image that he actually suggested NASA point their HiRise cameras at that location. He suspected they might find something interesting there and they did —flash water movement and evidence of avalanches.

One of the best images to ever grace this blog has to be Don P. Mitchell’s re-renderings of Venera 13 and 14. A miraculous re-rendering of Soviet-era data to create a whole new “human eyes” look at the surface of Venus (I also took the liberty of (artistically) colorizing those images as well). Now Ted Stryk — no stranger to these pages — has taken a shot at Venera 9 and 10 as well. The results are not as amazing as Don’s earlier work but that is simply due the missions having a more limited set of data. I must add that it is pleasing to see Ted’s (a scientist) colorizing is similar to our own (not a scientist).
See the whole story of how Ted’s images were made here.
The above is an interesting project to image the full Neptune system based on actual data returned by Voyager. According to the article published along with the image — Rolf Wahl Olsen composed this scene from actual images from the departing Voyager probe. The rings (which were never photographed in their entirety) are based on over-exposed images and then density mapped to a model which was applied to the scene. Even the stars are based on one of the over exposed images of the rings which revealed what the probe would have seen and that field data was inserted from and image generated by Google Sky.
We have posted many images and preview clips for outsideinthemovie before. Here is another look at some preview stills from an opening scene to be unveiled at an event on Sept 17th in Austin, TX. Steven Van Vuuren — the film’s creator — tells us these images begin a pan out from Earth to the surface of the moon which culminates in a trip through the Solar System on the way out to Saturn.
For those who may not recall, the film’s focus is on the Cassini Mission at Saturn and uses only real flat image photography returned from robotic spacecraft in a new technique developed by Van Vuuren that feels 3 dimensional. No renders will be employed and is therefore — a more realistic trip through interplanetary space than anything we have seen before.
This composite has been kicked around a bunch on unmannedspaceflight.com. Contained within it are two separate images taken by the Cassini mission at nearly the same time but different exposures. Looking at this scene with human eyes, the big difference would likely be that the geysers would not be blown out and would look more like a multiple of gentle hazes spewing upward. The other big difference would be that you were somehow on a mission to Saturn and not browsing the web.
Above are the two original exposures. These were merely combined with a photo editing tool. The geyser haze was blurred in areas to clean out compression artifacts and the color was artistically added by Gordan Ugarkovic. While the color is artificially generated, it does accurately reflect the same overall appearance of most natural light images of Titan.
If you haven’t followed the work of Stephen v2 and his film “Outside In”, you might want to take a look at what he has in store for us. Using only still images from the Cassini mission, Stephen is making a very impressive tour of the Saturn system without using any CGI, 3D models or textures. While those techniques make great Hollywood films they often fall short of making something that is actually a real place… look real. See below for a very brief clip of how this all ends up looking with a much better and longer clip coming in the near future.
I had really always thought it would be so cool to do a poster set with great design for each of the planets. I actually started a design for the Cassini at Saturn mission, but have yet to complete it. Sure enough someone comes along and knocks the whole system out in one fantastic series. Beat me to it!
Gordan U compiled this image of Enceladus lit both by Sun and Saturnshine. The side lit by reflected light from Saturn is in infrared and in the original appeared in a green hue. I took some liberties and imaged it as I would imagine it really would appear to the eye in Saturn’s more orange/yellow hues.
Worth noting tomorrow the images are due in from Cassini’s closest approach yet through its plumes. Hoping for some amazing material.
Not at all meant as a “gotcha” at all… but I just love when I take the time to clean these up and people start using these my clean-ups over the ones officially released. Daily Galaxy posted my Comet Halley clean up and I knew I recognized it as my handy work. They most likely got it off Google image search.
Nice example of science meets Hollywood.
Jason Perry has been featured here a whole bunch lately as he has been uploading newly processed Galileo images nearly every week (not to mention the recent New Horizons set). Some of these images would make great wallpaper displays, but the only issue with some are missing data regions and the noise that is common with hires images from the Galileo mission. Wanderingspace has attempted to artistically replace and clean of few of these images and will be posting the results of these for the next few days.
The region shown is the most famous of Io’s active volcanoes Prometheus. Normally we see this volcano at the edge of Io’s limb to view the plume clearly on profile, but here Galileo views this very active region from above during a flyby on orbit #27. The reddish haze surrounding the area is either the plume itself jettisoning materials or could also be deposits lying on the ground – perhaps Jason will comment and clarify.
The above image is the Jason Perry original and the missing color information is apparent (only the green channel was provided from the mission). The noise at this scale is less apparent but much more visible on the hires version. It is important to note that the wallpaper version is an artistic attempt at cleaning and replacing the missing data and is meant for display viewing not science!
IMAGE NOTE: As stated above – the missing color data was colorized in the region it was missing and some of the thin strips of missing color data was simply replaced with new image information. You can also see areas at the edges of the composition that were filled with duplicate image data to fill the wallpaper frame most notably at top right and bottom left. The remainder of the image is original except for the noise reduction provided by Photoshop.
Jason Perry’s most excellent Io blog (who would have ever expected there would be an Io blog one day) is loaded with his finely reprocessed Io images from the historic Galileo mission. Some of the more dramatic images were only captured in monochrome (that is black and white to most), so I thought I might try and colorize one of these images just for shits and giggles.
The image is that of Hi’iaka Patera and two nearby mountains (taken in 1999). The tallest peak is about 11 kilometers high. The dark features are usually thought to be calderas, however the dark regions here could be depressions that were later filled by dark lava flows. Galileo took the images at from about 26,000 kilometers.
The colorized image is merely an artistic impression. You can see where missing data has been “filled” in with texture by comparing the two images and seeing where the composite left gaps. The color information is wholly interpretive and based upon colors that appear in many other Io images but are not at all matched up to the region specifically. The real image was processed by Jason Perry and the original image is located on his page of Galileo Io images from orbit 25.
A recent post on unmannedspaceflight.com inquired “What’s your favorite view of the poles?” and Philip Descarfino (who did the colorization work) responded with the above image. According to Philip, “I find this image one of the best of HiRise so far. You really get the feeling of staring off into the distance from just above the surface instead of looking directly downward. It’s mostly an illusion, but it works quite well in this image.”
NOTE: Technically the image itself is interpretive in that it is not an RGB composite but instead a colorized black and white image based upon other color images from the same region. Usually you can almost tell from a glance when this is done, but this one looks spot on.
The one Saturn image that we keep coming back to at wanderingspace seems to be the Ian Regan portrait of Saturn. The composition, angle and color captured in the shot somehow seem to be better than any other. While there are a few other full Saturn images now available from the Cassini mission, none seem to have captured the drama that this one does. The angle that the ring shadows fall on Saturn’s disc, the phase that Saturn happened to be in at the time and the color available as the shot was taken from a more northern position. However, trying to apply the image to larger scale resolutions was not possible as the resolution in the orignal would require that the rings be extended to fill the frame on the left, right, bottom and potentially the top as well (I was also curious to see if the image was just as impressive if it was not angled and cropped as it is in the original). Extending the rings in one direction is easy enough, but doing it on all sides is near impossible to try to do in any image editing software such as Photoshop.
Instead, a one pixel wide swash of the rings was sampled and turned into vectors using Adobe Illustrator. This further allows Illustrator to stretch and curve the ring information captured without having to worry about resolution or pixel distortion. The row of rings was then applied to a brush pattern and applied and wrapped to a simple circle shape. Now the rings are in full circle and the proportions are adjusted. That full set of rings was then rendered in 3-D software and the correct angle as well as perspective was applied and matched with the original Ian Regan image underneath the render for reference.
After that, all that is left to do is merge the Regan image to the rings (and maintain as much of the original image as possible) and artificially add the disc shadow that would fall upon the rings behind the planet iteself.
