Not totally sure what this film will be like, but the potential of someone using the best imagery of the Cassini mission to create 3 dimensional environments set to music seems quite exciting. There’s not a ton of animation on the site, but what there is seems pretty good (despite the numerous screen shots of the back of someone’s head watching various pop stars?!). The above image is a still sample of what one would hope would represent the majority of what might be coming. Go to outsideinthemovie.com and check out the clips in the WATCH section, especially the “Basement IMAX” one which explains part of what he is attempting. But in order to make it happen, it seems donations are in order. Open up your wallet and help make it happen or take part in the process by submitting some images of yourself as requested by the creator (see the SUPPORT section).

Image Note: According to the film maker, “There is no computer-generated imagery in the film. No 3D models, no texture-mapping or any other rendered data. The only thing that has been done is taking many actual photos (including some high resolution mosaics) and using some very special and computer-intensive processing to create the feeling of depth and movement”.

Rather than waiting for NASA or U. Gordan to colorize this recent image of Enceladus against Saturn, I took it upon myself to fake it myself. I usually do not like to do it this way as it potentially misrepresents what the actual colors may look like, but I really think that these faked versions (also referred to as artistic representations) are likely pretty close. What was done was to add colors to the image based upon what other color images of similar conditions have looked like. The only thing that may be off is that the ring shadow colors may have been that Saturn peach (which in shadow looks brown) rather than the blue-green used here. Since other images of Dione shot against Saturn ring-shadows had the blues in them, I thought there was a pretty good chance this did as well. In the interest of telling the truth the originals have also been included.

Turns out U. Gordan did do one as well here.

Of the recent raw images of Enceladus, these had some interesting qualities I thought worth posting. They are more of the over-exposed variety for the purpose of exposing the geysers that have been discovered in the southern regions. I just thought at this further distance some of the images had a different feel to them. I highly recommend clicking on them for the high-res versions as nothing can be seen from the above thumbs.

Additionally, not sure… but I am thinking that third image may include the torus generated by the geysers or is that just a lens distortion of some kind?… anyone? I am thinking it is not an artifact as you can see a shadow of enceladus cutting through it diagonally in the upper-left.

And the wallpaper.

When the Voyagers sped through the outer Solar System in the 1980’s they returned the first images of the smaller moons of the Solar System, those of Saturn and Uranus. These bodies are large enough to maintain a spherical shape – but are considerably smaller than the junior planet sized class of moons which would include Titan, our own moon and a five others. At these smaller sizes (ranging from around 400 km to 800 km in diameter) the gravity is expected to be too weak to hold down any kind of atmosphere and the mass too small to generate any kind of internal heating. These are two factors that usually result in any kind of intriguing features like weather, volcanos, tectonics, geysers or more simply – anything that is not just another crater or the result of some kind of an impact. Nobody was expecting to find anything of interest which could be dated as any newer than from the time around which the Solar System was formed. Even our own moon, at its much larger scale, is for the most part “dead” and has been unchanged since it cooled off millions of years ago.

Well, whenever making assumptions about what one might expect to find upon exploring the Solar System, we are always prepared to be delightfully wrong. One the smaller moons of Saturn, named Enceladus, did turn some heads when the Voyagers sped by in the early 80’s (see above), but it wasn’t until Cassini arrived that it turned out to be an unexpected jewel in Saturn’s crown. From some vantage points, looking at Enceladus you might note the “muddy” looking impact craters on the surface and the unusually smooth surface in some regions, but apart form that – you would think that Enceladus was much like the other smaller moons of Saturn and Uranus – cold, cratered and frozen to the core. There didn’t seem to be anything going on around this tiny world any newer than perhaps a few tens of millions of years.

In 2005, the Cassini spacecraft got a better look at Enceladus and in particular noted a large area somewhat devoid of impact craters with unusually smooth ridges or “tiger stripes” (see above image of Enceladus from 172km) in a large southern region of the small moon. A lack of impact craters usually tells us that what we’re looking at is geologically active and depending on how few there are, tells you how young the surface is. The lack of almost any kinds of craters in this southern region led some to wonder if there may be some kind of unexpected activity going on, namely geysers (see below).

so in 2006, Cassini took an over-exposed look at a thin crescent Enceladus and there it was… a number of active geysers spewing out water ice miles into the space around Enceladus. Suddenly this tiny cold dead world leapt to life and is even rivaling Europa at Jupiter in terms of generating excitement for possibilities of finding life. Here on Earth we have come to expect life to rise anytime you have water in some fashion available. Life forms it seems, especially ones called extremophiles, seem to figure out a way to survive without sunlight, oxygen and nearly every other element larger animals like us need to survive. The only one thing that seems to always need to be present though is water. So whenever scientists find water in some form on another world, speculation starts to rise in the possibilities that life may have taken a foothold there and could possibly have survived and evolved to the present day.

Theories are still being drawn up to explain the activity on a world that should be frozen solid to the core and as “dead” as an asteroid. A likely guess is that something akin to what is happening on Europa is also happening at Enceladus. Its proximity to Saturn and the fact that it is largely made of something more easily melted such as water ice instead of rock (as Mimas is, which is actually in even closer to Saturn). What is curious is why the activity is isolated to the southern region? Up north the moon looks almost as battered as any other which establishes that these regions are fairly old.

For some years now a Europa Orbiter mission has be on the drawing boards at NASA, but many have begun to challenge the idea that the next Cassini/Galileo class mission to the outer Solar System should be to Enceladus instead of Europa. While Europa is active in some form, it is unclear what one may find at the surface. The meat of what we’re looking for may be miles below the icy crust and nobody is sure what kind (if any) of access there may be even at places where the ridges seem fresh and recently broken. Whereas, on Enceladus, there are active geysers currently releasing materials into space which makes capturing some of the materials much easier if not actually having access through some form of cryo-caldera. One attractive idea is to have some form of mission to Saturn/Enceladus that works similarly to the way Stardust worked. Simply fly in close to the active region, open up the collector and return it to earth. This worked fantastically at the comet Wild 2 and there is no reason to believe that it couldn’t work just as well at Enceladus.

NOTE: At the time of this writing, some questions have been raised about the nature of the geysers on Enceladus. A new model proposes that these fountains may not be composed of water ice.

WALLPAPER NOTE: the wallpaper image above is a composite image where the overall scene is actual, but the details of Enceladus’s geysers are from actual images of the geysers laid over the top of the background image. In actuality, the details of the geysers are only visible with over-exposed images which would make the relatively well exposed background scene impossible to image in the same exposure.

A tiny moon named Janus with a back drop of Saturn’s cloud-tops. There is not much to say about this tiny place other than the odd nature of its shared orbit with another tiny moon named Epimetheus. About once every four years they approach one another and swap orbits without coming any closer than 10,000km.

IMAGE NOTE: The image original was black and white and color was added based upon numerous images of Saturn’s cloud-tops. As with many tiny moons, the black and white nature of Janus was just maintained as it is not expected to have looked any different in color.

The NEAR spacecraft was designed to visit a few asteroids with the main target being one named Eros. This probe was meant only to orbit this object closely for a year… and it did. But as the probe ran out of feul and for lack of any reason not to, the controllers decided to attempt an impromptu landing on the surface. Even though the probe had not been designed to do this (it lacked landing gear of any kind) they managed to “rest” the probe carefully upon the surface in 2001 and it continued to transmit information back to Earth for more than 2 weeks from the surface.

Image Note: The color of the asteroid itself was enhanced to match that of the close up image included in the upper right. The original full image was black and white.

During the cold-war between America and the Soviets the real race was to the moon, but once that race was won a lesser race began to see who would master Mars exploration. After an unbelievably long series of failed Soviet missions to Mars — America managed to take the lead position in Mars exploration as well, with the Mariner and Viking missions. So the Soviets turned their eyes to our other neighbor, Venus, which seemed to garner very little attention from America apart from a few flyby missions. The Russians had Venus all to themselves and really didn’t have to be too concerned with anyone beating them to the punch.

So during the early 70’s the Soviets managed to be quite successful with multiple Venera missions to Venus which included various flybys, orbiters, radar mapping of the surface and even multiple landings on the surface. Some of the missions had failed, but most completed their missions and we have the above color images to prove it. Recently though, I stumbled across these projections of the above images which I have never seen before.

Someone who knows about such things, Don P. Mitchell (see more on his blog mentallandscape.com) had returned to the original data sent to us by the Venera spacecraft from over 30 years ago and with new computing techniques, managed to reveal to us Venus anew. Instead of just looking at some stones and tiny hints at what a Venusian sky might look like, these projections show what it might actually look like walking on the surface of Venus. The main part of the image above is a composite from spherical projections, which are seen at the top-right, remapped to perspective projections. The way the projection works is the closer you get to the very center of the image, the less accurate the representation may be. However, there is evidence in the data to assume most of what you see here even at the very center where the data was at most thin, is still fairly accurate.

Unfortunately the new projection images were only in black and white and i really missed what seemed to be really fascinating color from the original Venera images… so I tried to colorize it to match the originals.

This interpretation is artistic and not based upon any data other than looking at the original images and trying to assume some of those colors back into Don’s black and white image.

Io is the first large moon of Jupiter and is the most geologically active body in the solar system. Its close proximity to Jupiter and tidal forces from the giant and its 3 other giant moons push and pull the moon apart internally. This causes Io to turn itself inside out and fuels its many active volcanos. Due to this constant volcanic activity the surface of Io is quite young, continually being reshaped with not a crater to be found.

Image Note: The image itself is largely original and complete. I added the “dark side” details and completed disk. The the two plumes showing at the edges of the dark side of the disk are also additions. The plumes are taken from other real images and they do appear in true scale, however some brightening of these plumes were likely applied to these original images to show detail, so I darkend them a bit and reduced the color saturation that usually results from these manipulations.
