You need to upgrade your Flash Player The theme of this blog is not only and obviously space, but in particular “terrestrial worlds”, places that tend to have surfaces on which one could walk or at least attach oneself to. These places sometimes also have other earth-like familiar features such as atmospheres, weather, volcanos, geysers and perhaps, we are finding, even exotic oceans, rivers or lakes that are not necessarily made of familiar materials we are used to here at home. The second theme is imagery. Occasionally I do some retouching of images when needed if an image is incomplete or sometimes “dirty” or noisy. I will attempt to correct image shortcomings based upon other images or well-accepted presumed attributes. When this is done, notes will be offered as to what was added, why and sometimes how it was done. This way no one should ever wonder if something they are looking at is real or photoshop.

An X Asteroid?

February 8th, 2010

What NASA thinks we might be looking at here is an asteroid that was recently shattered by another asteroid, giving it a comet-like appearance. It stays within the asteroid belt, so it cannot be a comet as those objects are known to be dusty ice-balls that stay in highly elliptical orbits around the Sun.

See the Hubble site for more.

Ross Berens Ruins My Dreams

February 3rd, 2010

I had really always thought it would be so cool to do a poster set with great design for each of the planets. I actually started a design for the Cassini at Saturn mission, but have yet to complete it. Sure enough someone comes along and knocks the whole system out in one fantastic series. Beat me to it!

The Art of Michael Paukner

January 24th, 2010

Admit it, deep down inside we (or at least I) all secretly want to explore the heavens untethered from the Earth and unlock all the mysteries of the universe. Perhaps that is why the beautiful info-graphic art of Michael Paukner is so appealing. His work focuses on many scientific themes such as space exploration, as seen in this poster of the Solar System as it is known today (above), to more conspiratorial “junk science” theories like numerology, the Doomsday Planet (follows the link) and that crazy Aztec calendar that ends in 2012.

Could the Phoenix Rise Again?

January 18th, 2010

It seems pretty unlikely to happen, but starting on January 18 the Mars Odyssey Orbiter will begin listening for signals from the Phoenix. The mission ended last November as the Sun became too dim to continue to provide the solar cells enough energy to keep Phoenix warm and operable. The lander was never intended to survive a Martian winter and has most likely been devastated by the extremes and unlike the rovers, Phoenix is in a polar region which makes those extremities of a Martian winter even greater. Now with the end of Martian winter comes the addition of more sunlight, comparable warmth and therefore a reason to think maybe we can grab enough power to wake up and resume operations. So nobody really expects a technical miracle to take place this week, but in the unlikely event that the lander has survived… the science teams already have a plan in place to take that advantage.

Above is an impressive mosaic image of the frozen water that was found beneath the lander later in the mission. It is thought that the thrusters (which enable a soft surface landing) kicked away the top soil on the way down, revealing a sheet of frozen ice water right underneath the lander’s feet.

Prometheus, Small Moon of Saturn

January 15th, 2010

Prometheus is the small moon that shepherds Saturn’s outer “F” ring and causes those crazy waves in the particles that make up the ring itself. The phenomenon has been the theme of at least 3 different animations here on wanderingspace.net. The image above is what that small moon in those animations looks like from 60,000 km taken by Cassini on Dec 26, 2009.

Back-Burner Image: Saturn Clouds

January 2nd, 2010


Haven’t come across too much lately. When that happens, I like to post these images that have been sitting around collecting virtual dust. Cloud top formations on Saturn taken by Cassini in 2009.

Beautiful set of posters by Simon Page. There are 10 total. See them all here.

GOOD on NASA Missions

December 8th, 2009

The site good.is has this great section called “Transparency” where they illustrate complex and hard to understand topics. Check out this magnificent chart of all the probes that NASA has sent past Earth orbit.

Through the Plumes!

Gordan of course.

The Fountains of Enceladus

November 27th, 2009

This has to be one of the greatest, most alien images ever taken from robotic spacecraft. It approaches how I might expect Enceladus to be depicted if it were in a Star Trek movie. As if the plumes at the edge of the disk back-lit by the Sun were not enough… the trail of smaller plumes breaking through the darkness is absolutely fantastic. The above is a real image but the color is an artistic interpretation by someone would know. Considering how little color is usually found at Enceladus, we can image this is really as good as if it were compiled from a full RGB set of filters. A larger monotone of the same image here.

This image was compiled by Astro0 on unmannedspaceflight.com. Also one of the best views staring down the length of one of Enceladus’ “tiger stripes”.

Ever so sharp look straight down on the South Pole of Enceladus from 1,855 km.

Rosetta Skims Earth

November 13th, 2009

On its way to a 2014 rendezvous with comet 67P/Churyumov-Gerasimenko, the European Space Agency’s Rosetta spacecraft, with JPL instruments on board, flew past Earth today to pick up energy.

The Plumes of Enceladus in Color (kind of)

November 6th, 2009

Like the Saturnshine image posted earlier, this is only an estimation of a true color image. Five sources were used to compile this image; clear 1, clear 2, red, blue and another clear filtered image was used to replace the missing green to round it out (this work by S_Walker from unmannedspaceflight.com). We then additionally cleaned out artifacts from the original images and blurred the surrounding geyser haze largely to eliminate posterization noise.

This is the first time anyone has been able to attempt a true color view of the geysers with the availability of the red and blue images. Also a bonus is the considerable amount of Saturnshine seen on the dark side of the moon.

Enceladus at 9,988 km

More coming. Looks like a nice encounter.

Dueling Enceladian Light Sources

November 2nd, 2009

Gordan U compiled this image of Enceladus lit both by Sun and Saturnshine. The side lit by reflected light from Saturn is in infrared and in the original appeared in a green hue. I took some liberties and imaged it as I would imagine it really would appear to the eye in Saturn’s more orange/yellow hues.

Worth noting tomorrow the images are due in from Cassini’s closest approach yet through its plumes. Hoping for some amazing material.

Umbriel, Moon of Uranus

October 31st, 2009

A view of Umbriel from Voyager 2 in 1986. Thanks to Ted Stryk who specializes in re-imaging images from old missions with today’s advanced computing. There are few images of this place and no missions planned any time soon… so these may be all we ever see of it in our lifetime.

The most interesting detail revealed in these images is the bright white disk that appears at the top of this image which is actually at the equator. Since the Uranian system is turned on its side almost 90 degrees to the rest of the solar system, Voyager passed all of its moons at nearly the same time. The orientation means we are actually seeing the southern pole nearly straight on in both these images. Such an unusually high-contrast feature reminds one of Saturn’s strange moon Iapetus. It could be the same phenomenon that made Iapetus look the way it does may have also been at work on Umbriel.
