Having followed the activities of a small army of freelance space imagers that lurk in various places on the internet for about 10 years now — it is truly unusual for me to come across images that I know I have not seen before. Michael Benson’s exhibit titled, “Planetfall” at the American Association for the Advancement of Science offers offer fresh views from missions as old as Viking and as new as Cassini. What originally caught my attention was an image of an actively spewing Enceladus that is exposed in both Sun and Saturn shine — a view I have surely seen before, but never so detailed or dramatic. Even more surprising and rare is a new global composite view of Uranus with a complete and continuous ring taken by Voyager almost 30 years ago.
The show ends soon (June 28, 2013) and is located in Washington DC.
You Are The Sun is the latest space themed tee by Chop Shop Store. Following on iconic tees that collected various deep space missions and historic Earth orbit missions, this new design draws a new picture of The Solar System as we know it today, complete with Carl Sagan’s pale blue dot.
With your head as a stand-in for The Sun — the tee includes all 8 planets, 7 major moons, The Asteroid Belt and even details little Pluto lost among countless Kuiper Belt objects. We are now providing yet another link here to get it for Men on American Apparel 2001 or Tultex tees and for Women on American Apparel 2102 tees.
We posted a similar image of an Io and Europa mutual event from the New Horizons mission a few years back when it zipped past Jupiter on its long journey to Pluto. Our hero of freelancer image compositing Gordan Ugarkovic now presents to us a much better view.
I count at least 4 if not 5 active eruption on Io in this version. The level of detail improvement from the same encounter is amazing. Old missions keep getting newer.
Paul Schenk has been taking new and old data from missions to the various moons of Jupiter, Saturn, Uranus and Neptune and building 3-D models of what it might be like to fly through some of their more fascinating features. These are renders built from actual images, so often you might see areas of lower resolution due to a lack of better mission data. The one posted above of Hi’iaka Montes on Io is one of the best on his youTube page as the data available from the region is mostly in high resolution with few gaps.
This is so nice, but I am furious that I didn’t get to design this. This is Information design at it’s best naturally by National Geographic. You can see 50 years of robotic planetary exploration at a glance. It even includes failed missions represented by darker desaturated lines. As far as I can tell the cream colored lines are US and the red ones are Soviet. Interesting to see how many of those lines go dark around Mars.
Now where does one purchase such a thing? Perhaps this month’s issue of NG? Here is the link to it on their site complete with zoom viewer and them some kind samaritan posted a hires version to flickr.
I usually do not go for montages of planets for a variety of reasons, but this family portrait of the 4 Galilean moons of Jupiter is quite gorgeous. They are easily the most fascinating and beautiful bodies of our system of worlds, save for perhaps Saturn and its rings.
Another work of art by Ted Stryk whose old blog Planetary Images from Then and Now has come back from the dead with vigor!
Not to re-post old material, but our iPhone planetary skins were recently posted to fuelyourcreativity.com for free download. So I thought I would just remind everyone and maybe direct a little traffic love their way.
It is final. NASA (and ESA) have selected the next flagship mission to the outer planets. The target is the Jupiter system, and by “system” I do mean system. NASA’s side of things will concentrate on a Europa orbiter which will observe Jupiter’s moon in details that we have never seen before. See this youTube video for a good overview. The last time we were near Europa enough to make close observation was with Galileo, but problems with that spacecraft resulted in a limited amount of data that one would expect from such a long orbiter mission such as Galileo.
Beyond Europa, the mission will also be close enough to do great observations of its closest neighbor, Io, as well – of course – as it’s host planet Jupiter. Also worth noting is the possible adoption of an Io specific orbiter as part of the New Horizons class of spacecraft whose targets for the next decade have yet to be determined.
Lastly, and certainly not at all a small thing… ESA will be running a Ganymede orbiter to work in tandem with the Europa mission. The two missions are more like partner missions such as the 2 Mars rovers than separate ones. They seem to planning for them both to arrive at the same time (or even launched from the same rocket, is that even possible?).
Download this pdf to check out these soon to be produced desktop globes of Jupiter’s moons and contact them about any interest in buying them here. These are cardboard-substrate globes on simple plastic bases, but they still look pretty cool. Even at the high price of $300 (a pre-production estimate) – I have to say that I am pretty tempted.
A rare view of Io and the small moon Amalthea seen in the same view was taken by Galileo and recently reprocessed by Ted Stryk (his page is linked lower right). Amalthea is a tiny elongated moon that appears to be quite red. It is assumed that the longish shape and red hue come from the deposit of materials ejected off Io and spiral inward to Jupiter, swept up by Amalthea in its orbital path.
A similar phenomenon has also been seen at Saturn with moonlets that “sweep” ring materials.
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.
The reason the left side is so blown out is due to the fact that the image was overexposed for Jupitershine and New Horizons cameras were designed for low light at Pluto which is ideal for observing the moons of Jupiter by light reflected off their host planet. However, doing this results in the total overexposure of the side lit by the Sun.
This is another Jason Perry image and the original can be found here. Wanderingspace simply removed the lens flare noise and the overexposed color noise. He just added some New Horizons Io images that he has personally reprocessed on this page.
