Ranger IX, Camera A

A while back wanderingspace posted 2 great animations of the Mariner flybys of Mars. They had a great nickelodeon feel to them and are two of the best posts on this blog (in our opinion). So when Emily Lackdawalla posted recently on the first “earthrise” as seen from a probe in orbit around the moon – she linked to this great database of moon shot mission images from the 60’s. Glimpsing at these collections, it was clear that there existed the same potential for another nickelodeon style animation of a trip to the moon.

The mission shown above is Ranger IX and there are many more potential animations that can be made from other Ranger missions or from the Lunar Orbiter series of images. Maybe one day.

Sorry for the huge file size… about 1M.

More STS-118

Yet another from 118.

One of the best details of this one is that you can see an astronaut intentionally peeking out of the second window on the left. Seeing a person looking out the window reminds us how real it is. It’s like seeing a friend in a car go by… only our friend’s car is floating in the hostile vacuum of space.

Another STS-118 Image

While looking for stunning images from STS-119, came up with this missed gem from 118. Again… was there a photographer on that mission?

Earthrise as Seen by Kaguya

Thank you JAXA. Last time we saw something like this was round about 1974… If you want a peek at one of the HiDef movies being shot by Kaguya see this link here.

Comet Holmes from November 4

Must have missed this earlier image of Holmes. In the interest of seeing the comet better, the background stars were reduced with software and the surrounding space around it was darkened. You can see the original image here taken by Ivan Eder.

Comet Holmes from November 8, 2007

Here is Comet Holmes just a week after the previous post. The original image had multiples of star trails which have been quickly removed in Photoshop, probably resulting in some subtle “clumping” artifacts in the surrounding coma. For reference, here is the orignal by Chris Schur.

Comet Holmes from November 1, 2007

Comet Holmes is a small comet that travels between the orbits of Mars and Jupiter. The comet reappeared to observers around the time that was expected (for those who follow such objects), but the only difference was that around October 23 the comet began to get much brighter. In a 24 hour period the comet was thousands of times brighter than it had been the day before. At the time of this post, it is reported to be appear in the sky at around 1/3 the size of our moon and they say it is still expanding. There are no “official” theories as to what is causing the activity, but many assume that there had been some kind of collapse of materials on the surface which would then cause a large amount of material to escape into the space around it.

The comet seems to lack the usual comet tail and appears to be fuzzy and round, as we are looking at Holmes straight down through the tail end of it from our position here on Earth. The comet was originally discovered in 1892 due to a similar outburst which now seems to be repeating itself.

The image above was provided by wikipedia.com and only credits the image as being submitted by user Spanto and was taken in Barcelona , Spain, dated Nov 1 2007.

The iPhone Set 01: Bodies of Major Interest

If I am going to keep making these things… I’d be a fool to not include a set for the Apple iPhone. Coincidentally, when you purchase your iPhone and do not yet have a phone service, the phone displays a full-disc image of the Earth pretty much displayed exactly as these do when uploaded to your iPhone. So in the spirit of continuity, you can now opt instead to have Mercury, Venus, Earth, The Moon (Luna), Mars, Jupiter, Io, Europa, Ganymede, Callisto, Saturn, Enceladus, Titan, Iapetus, Hyperion, Uranus, Miranda, Neptune or Triton grace your screen instead of the default Earth.

The easiest way to install wallpapers to your iPhone is to make a special set in iPhoto and simply drag all the files to that folder. Then in iTunes have your iPhone sync that folder to your photos collection. After that it is as simple as opening the “Photos” area of your iPhone. Go to your new folder of images and open whichever image you want. Then tap on the image just once and assign it as a wallpaper using the “Use as Wallpaper” button in the lower left corner of the screen.

If you have a PC I have no idea in hell how the hell you get images into your iPhone. I would buy a Mac… you have an iPhone and use iTunes… you are half-way there.

For a version of these with no graphics see this link.

The Regan Saturn Portrait Extended Mix

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.

Prometheus Desturbs a Ring

There have been some nice NASA animations of the interaction between some “shepard” moons and the rings, but this has to be the most impressive. There are some blank frames in there for gaps in the data… but the effect is still easy to follow.

Wallpaper 2560x1600 Set 03: The Planets

The planets – the complete set for collectors! While there are literally thousands of images of the planets to choose from… full globe high resolution images are actually fairly rare. They usually require many exposures to be stitched together to make one large complete image. This is not only difficult to work out across the great distances of space, but also soaks up a large amount of valuable spacecraft time and energy. This set represents the best available images of each planet in our Solar System.

Sorry, no Pluto for more than one reason.

2560 x 1600 Set 05 : Saturn Scenes

Among the various worlds in our celestial neighborhood, Saturn stands apart as a most photogenic. With the help of a complex system of rings it naturally lends itself to more scenic images as compared to the more detail oriented images we see from such other places such as Mars or Jupiter. The “Saturn Scenes” set (downloadable here as a zipped file) was compiled from some of the best scenic images from the Cassini mission that had the potential to fill a 2560x1600 frame.

In order to completely fill that frame out some rendering and sampling has been applied to the original images. These additions are briefly noted in the images themselves and are as noted here…

DIONE AND SATURN features the moon Dione passing in front of the edge of Saturn’s disc. The original image would only fill about 1/4 of the frame so some of the details have been sampled and expanded to fill out that full frame’s proportions. The details of the rings are sampled from this image and based upon other photographic references. The left 2/3 of the rings seen here were rendered and are not actual. The lower 1/5 of Saturn’s disc was sampled and extended from the original image. Lastly, the top darkest ring shadows were rendered based upon a fair amount of actual data that was actually present in the original but was cropped short.

SATURN (which is named “SATURN-2.jpg” in the file name) has had a considerable amount of rendering to extend the details of the rings to fill out this larger 2560x1600 frame. The original color composite work was masterfully performed by Ian Regan for unmannedspaceflight.com and has become a wanderingspace favorite. In order to extend the rings to fill out the frame as accurately as possible, a one pixel wide sampling of the full set of rings was captured and digitally translated to vectors. These vectors were then stretched and applied to a circle path which was then rendered in 3-D software to achieve the correct perspective of the original. Once a match was made, the new vector based rings were then blended into the actual original image and some masking was applied to represent Saturn’s shadow falling upon the rings. Despite the heavily rendered nature of the rings, virtually no part of the disc of Saturn itself has been altered and is 99.5% original and actual.

All other images are actual and unaltered.

Cassini Team Shows Some Color

NASA released an unusually large amount of color images to the Cassini website recently. Most of what is shown here on this site are actually images put together by freelance imagers who access the raw files and do some stitching together of filtered images. Color images coming straight off the Cassini website are a rare event, so when about 8 appeared in the gallery a few days ago… it was an unexpected gift. Saturn as seen from the unlit side of the rings.

A family portrait of the Saturn System. Moons visible in this image (you need to click the preview) are Dione at far left, Enceladus near the left side ring edge, Mimas a speck on ring shadows on the western limb, Rhea against the northern hemisphere, Tethys near the right ring edge, and Titan near lower right.

Titan and a small moonlet named Epimetheus share the frame with Saturn’s rings.

A rare color view of both Saturn and Titan in one frame. This is the only one of its kind thus far in the mission.

A small rainbow appears as sunlight streams through Saturn’s rings.

Japan’s Kaguya: Orbiting and Releasing Probes

Always interesting to see parts of a probe set against the celestial body it is observing. Unlike images that only include the target, these remind you of the presence of a probe or observer. It illustrates a clear difference between seeing these bodies from a great distance (say from a telescope like Hubble) versus knowing that these views were taken very far away from us here on Earth and in the proximity of a very alien world.

The mission Kaguya is Japan’s contribution to the International Lunar Decade which has only just begun and might hopefully end with some form of manned mission by or around 2017.

The mission has thus far released one of it’s two smaller probes (Rstar) which will independently orbit the moon and the second smaller probe (Vrad) will be set in orbit sometime today. The mission’s main objective is to help solve some of the mysteries of the moon’s origin as well as acquire a more complete understanding as to the moon’s usefulness to the human race and it’s potential role in future space exploration.

New Horizons is New Again

A bunch of new data was recently released from the New Horizons encounter with Jupiter in February. Included in that was this impressive composite of Jupiter’s clouds. The image is presented here in 3 parts as I just have not figured out how to post tall images in my build of WordPress without it scaling oddly into the page format.

The original released by NASA had an odd grey faded edge which looks fairly fake and manipulated. The description states that it was taken at the edge of Jupiter’s night-side, so we adjusted the above images to look more natural than the way it appeared here.

Rhea Transits Saturn

These images were taken of Rhea as it (and Cassini) sped across Saturn’s globe on August 30, 2007. The near-natural color images were composed from raw near-infrared, green and ultraviolet filtered files made available on the NASA-Cassini website. Some of the details may have been enhanced through the use of infrared and ultraviolet in place of red and blue… but they have been adjusted to reflect what we assume is closer to actual natural color. From approximately 93,823 km.

From approximately 78,967 km.

From approximately 53,788 km.

Cassini at Titan Again

Probably there are images like this of Titan every time Cassini makes another pass. This week marks the 36th time since the start of the mission the spacecraft has visited the large Saturnian moon. So these images are probably similar to the other 35 times Cassini snapped some RGB filtered images, but we are hoping to score a more traditional “portrait” of Titan one day that isn’t another crescent image.

The first image is similar to one that we currently use as the “portrait” wallpaper for Titan (seen here). That one is starting to look a bit fake in the purple hazes while this new one seems to be a bit more believable. You can see the thickness of the atmosphere when the Sun is directly behind Titan, which tends to be one of the more interesting ways to view this world. Also visible is what always appears to be a “break” in the uniformity of the haze at the lower-left corner (You can also see a similar break on the next image on the lower-right).

This second one is a more true “portrait” image of Titan in all its featureless glory (have we mentioned how much it just looks like Venus?). The difference here is you can really get a sense of the moon being “wrapped” in its atmosphere on the upper-right hand side where it almost seems like you are peering through the haze to another layer just below.

The Carnival of Space 22: The Art of Space

I am honored to be the host of The Carnival of Space’s 22nd edition with a focus on the art of space. Wanderingspace considers images of our Solar neighborhood to be art in their own right, so here the line between art and science is thinly drawn to begin with. Enjoy the links! Recently artist Bettina Forget had one of her creations featured on the back cover of a recent Planetary Society periodical. She posts at her Inside the Artist’s Studio blog and recently mused on sketching at the eyepiece of a telescope and its benefits. Be sure to also take a look at her Moon Series, which is where the previously mentioned Planetary Society featured painting of Io and Europa can also be viewed.

Another fine arts bit of space creativity can be found in the recent work of artist Robert Whitman. Pixel Pusher has an introduction to his show “Turning” which features glowing, spinning sculptures of such moons as Europa and Ganymede while another installment involves a projection of Io. The show is currently on exhibit at the Pace Wildenstein Gallery in New York City. So hop on the subway, it closes on September 29!

If you don’t just want to look at space art but actually create it, Artsnova Digital Art and Space has a few words on a new NASA Space Art Contest whose theme is “Life and Work on The Moon”.

Still feeling creative? The Wired Science Blog is hosting a NASA Slogan Contest where we all have an opportunity to come up with our own slogan and submit it. This contest is only open to entries for about another 24 hours after this goes live, so hurry over!

In the strange category, The Podcast Troubadour offers up two Carnival of Space Themes for your listening pleasure. One is more theatrical and breaks into what can only be described space carnival music while the other will shake your descent stage thrusters. Yes... theme music for The Carnival of Space. The internet is a place where anything can happen and usually does.

If you are unfamiliar with the work of IMAX in a Basement you need to take a look at what exactly is coming out of that basement. The film “Outside In” is entirely made of Cassini still images and is somehow made into what feels like a 3-dimensional voyage to Saturn without the use of any 3-d modeling software. Check out his new offering of 100 Megapixels of Saturn Ring Magnificence with both a hires still and a sneak-peek video segment.

Bridging the gap between art and pure space science, I feel the need to link to Don Mitchell’s Mental Landscapes site for his Soviet Venus Images collection. This is not a blog... i know... but if you scroll about half-way down the page you will see his re-worked Soviet Venera images of the surface of Venus which is just about the most incredible feat i have seen by any freelance imager. Maybe you are familiar with his work already, but if not... every fan of space exploration needs to know that these images now exist thanks to Don.

Riding with Robots reflects on that recent Hubble image of Ceres in, “The Clear Power of a Fuzzy Image” which according to the author “embodies his fascination with space exploration”.

While we are in a reflecting mood Cumbrian Sky compares the 1981 experience of images of Iapetus coming from Voyager to the 2007 experience of images of Iapetus coming directly to our computer screens from Cassini. Space exploration has certainly changed in 25 years. If you want to see more about the recent Iapetus flyby be sure to check out Emily Lakdawalla’s post on the Voyager Mountains and her most excellent link at the end of the article to the full set of images and metadata from the event.

For some off topic posts, A Babe in the Universe offers a new video Images of a New Space Age. Sorting Out Science considers the recent meteorite impact in Peru. Unenumerated has some real options analysis for space projects and takes a fresh look at risk evaluation for deep space missions. Robot Guy posts a whole episode of The Universe’s Mars Episode. Astroblogger captures the ISS whiz past Jupiter. Hobbyspace is telling us about how Google Moon is getting sharper as well as a new 3-D Hubble IMAX movie in the works. And Mr. Gerhards is hoping to record the goings on in going to see Shuttle launches before its too late.

Finally, some posts on two books from completely opposite ends of the spectrum. Lunar Photo of the Day takes a peek into the book-by-committee publication, “The Scientific Context for Exploration of the Moon” which is apparently the kind of book that may hold some sway in terms of Lunar decision making over at NASA. On the other hand, Music of the Spheres blogs on “Cosmos for Beginners” which, unlike the previous title, could be a nice purchase for children of all ages between 12 and 90.

Well, thats all for now. Make sure you bookmark some of these excellent blogs and maybe even subscribe to their RSS feeds. Remember, its the internet… all the planetary love you can ever ask for and its all for free!
