Mercurian Horizon
Mercury From 18,000 km
Messenger Reveals Unseen Mercury
Little coming in from Messenger at this point due to some unexpected bandwidth issues at the receiving stations. Apparently there has been some Ulysses (a separate Solar observing mission) anomaly that needed tending to and has taken up the available bandwidth that had been planned for Messenger’s data. The data is reportedly fine and ready for transmission to Earth, just a delay.

For now the mission team has released this view of Mercury from the historic swing by on January 14. Much (if not all) of this image represents areas on the planet never before seen by human eyes. Very moon-like… hoping for something to come from this encounter that will be visually exciting for we the unwashed-masses. That said, scientists and the planetary sort are thrilled to be seeing this local neighbor which has been long overdue for a follow-up mission to the Mariner mission of 33 years ago.
Mercury Here We Come
Today’s flyby will come as close as 200km from the surface. That is comparable to some of the close flybys of the Saturnian moons made by Cassini.
See here for Ted’s colorization of this image based upon his Mariner 10 work.
Mariner 10 Image Made New
According to Ted Stryk (a regularly featured imager) this image has been under construction for over a year (higher resolution available here). If you are unaware, to date… no color images have seen the light of day from the 1973 Mariner 10 encounter. So it is with unexpected shock that we are granted this fine image from an old encounter the night before we are expected to be dazzled with a plethora of new Messenger images.
Although different missions are handled differently than others, we may not be granted all images as soon as they are received here on Earth. For example, Cassini has its images open almost immediately through the raw files link… while ESA makes us wait (and still does) while they release “official” images and other reports to the press. The Cassini method is far greater an option as freelance imagers will get color composites up and available hours after an encounter while you may wait weeks for the official imaging team to get around to making color composites for public consumption. I fear the latter will be true of Messenger (especially as Mercury is not expected to be an overly colorful place), but most US based planetary missions have been great about sharing the wealth practically in real time… hopefully Messenger follows the trend.
So enjoy this for now — as stated by JRehling at unmannedspaceflight, “The best Mercury image in mankind's history -- for another week.”
F-Ring Animation
Prometheus disturbing the F-Ring as it passes. We have seen this animated before, but perhaps not from such a vantage point.
Improved Epimetheus Image Released
This improved image of Epimetheus was released to the Cassini site yesterday and as compared to this more raw image post from December 8, it is most notably cleaner, processed in color and appears to be much sharper.
This is a view of the moon’s more southern pole and there is speculation that covering a majority of this face is actually one large impact crater which could explain it’s flattened appearance. There also seems to be what looks like a deposit or “dusting” of material all over this face which seems to blanket flat areas and begins to fill some craters and other depressed regions. The moon is only about 70 x 50 km in size, approximately the size of a city such as Los Angeles.
Messenger at Mercury in 2 Days
Nothing to show at this point (except some distant calibration images), but Messenger will arrive at Mercury on January 14th. This is the first visit to the tiniest planet since 1973. On that visit the Mariner spacecraft flew by the same region 3 different times — therefore leaving more than 50% of this planet yet unseen by human eyes. With the arrival of Messenger, most of what has not yet been imaged will be revealed in 2 more additional flybys and surely 100% will be revealed once Messenger achieves orbital insertion in 2011. With the exception of Pluto and its partner Charon, Mercury represents one of the largest pieces of real estate not yet mapped or imaged by some kind of probe in all our solar system.
Earth Aurora and Crater from ISS
Above is an aurora as seen from The International Space Station. The large white circular feature seen at the top is the Manicouagan impact crater located in northern Canada.
NOTE: Some image alteration has been applied to remove a large amount of noise and discoloring largely from the area of black space below the Earth.
Wallpaper: Southern Saturn
The Gordan Ugarkovic fan club must be thrilled this week with all the recent Saturn images. This new one is among the best around, reminiscent of the fantastic Ian Regan composite. A gorgeous view of Saturn’s southern pole which has seen very little exposure in terms of global views (or near global) like this. The now famous “storm” dead-centered around the pole can be seen directly to the left of the image caption.

As always, the Ugarkovic flickr page for all the latest.
NOTE: An ever so slight amount of Photoshop image extension was applied to the far right side of the image only at the edge. Probably about .5% of the image.
My Sci-Fi Bookcover Past III
This one was fun as it was supposed to be based upon real science, so we were able to take advantage of more reality based imagery. The idea was to get a good image of an astronaut with a suitcase and just have that with the title. A google search for astronauts turned up this excellent image of a guy looking like he is literally truckin to the launch pad. So we switched the color of his uniform, darkened the visor (one of the only things you cannot do with NASA images is show an astronaut’s likeness) and tried to make the case look a bit more like a suitcase than an oxygen unit of some kind. It really was perfect, but not high resolution enough to go large… so to fill the frame other astronaut legs were added to suggest the story is about mankind, not just the dude with the case.
Of all the Tor Books Chopping Block executed, this was always a favorite of mine.
Saturnati IX
Gordan is having at Saturn again.
Wander In Space Tee at redbubble.com
We posted this tee available for sale at redbubble.com that borrows from the old NASA logo to create this visual play on words. The quality above looks a bit low, but see the link for a better representation.
This is the second tee we are posting here and due to a simple address error, we have not received either product to do a review. Once that happens we will post.
Saturn’s Southern Pole
And here we have another Ugarkovic gem.

Slow News Month (kind of)
I haven’t been able to keep up the site lately (and there really hasn’t been too much to post either). The intention is to continue the site as it had been maintained before the December slump after the new year. Happy Holidays.
Pluto Tee
Hard to find nicely designed planetary items. Too late maybe for Xmas, but certainly not too late to get it in time for New Horizons flyby in 2015!
