Historic Robotic Spacecraft Poster Survey

Our new Kickstarter project proposes the creation of three screen-printed posters celebrating the most popular and notable interplanetary robotic space missions in history. Going into this, we knew that poster #1  had to go to the hugely popular Voyager missions (shown above). However, we need your help selecting the themes of posters #2 and #3. So head over to The Planetary Society now to vote on your three favorite missions, but do it by the 19th to have it count for the poster selection. If this goes better than expected we could even wind up designing a fourth or fifth.

Discover’s Best of Amateur Imagers

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.

Enceladus Lost in the Ring Haze

The tiny but very active moon Enceladus is seen here lost within the E-Ring of Saturn. The moon, as many of us know, is quite active with cryo-volcanic geysers littered throughout the ridges of the “tiger stripes” found mostly in the moon’s southern hemisphere. Since most of the ejecta from Enceladus is jettisoned fast enough to escape the tiny moon’s gravity, most the material winds up orbiting Saturn itself and is therefore helping over a very long period of time to form Saturn’s E-Ring. This at least partly helps solve the question of where Saturn’s massive ring structure originates.

Best of G. Ugarkovic (Last 8 Months)

If you follow this blog on any basis, you might be well aware that a good percentage of the imagery is provided by our good flickr friend Gordan Ugarkovic. Here is a bit of what we missed from him in the last 10 months we were locked out.

Titan at the edge of Saturn taken 2011-05-21. Looks unreal. Like Titan was dropped into the scene using Photoshop. A sin I would never commit. See the lesser “official” NASA version released a few months back here.

Keeping with the theme of moons transiting Saturn. Here is Rhea and tiny Epimetheus doing what they do. Taken in 2010-03-24.

Finally, just to change it up… two moons against Titan, another of Saturn’s moons. Pictured above the Titanian cloud-tops is Dione on the left and Rhea on the right.

Okay, Set Scene: Rings, Titan, Geysers…

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.
