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.

Near True Color From Phoenix

Tuesday, May 27th, 2008

Phoenix Color by Gordan Ugarkovic

Near “true” color made by Gordan Ugarkovic using the only RED, GREEN and BLUE filtered images returned from the mission thus far. Additional adjustments were made by looking at the logo and the American flag (which we have an idea of what those color are supposed to look like) and adjusting the color of those items to appear as what we know are “true colors”. Logic then dictates that if those items are correctly balanced, then the Martian soil will also appear close to accurate.

Phoenix Landing as Seen by Mars Recon

Phoenix Landing as Seen by Mars Recon

This image represents the very first time we have been able to acquire a visual on any kind of probe landing on the surface of another moon/planet. What is (clearly) seen here is the Mars Phoenix lander in the parachute phase of its descent. You can even make out the shape of the thin threads that hold Phoenix tethered to its chute.

Normally a visit to another world is a solitary experience, but as many as 3 other probes already in orbit around Mars (Mars Reconnaissance, Mars Express and Mars Odyssey) were timed out to be in the general overhead vicinity of the Phoenix landing. It just so happens that one of them, Mars Recon, has very sharp eyes.

False Color From Phoenix

Until we locate some better “true color” images from Phoenix, this false will have to do.

First Images From Phoenix

Monday, May 26th, 2008

This mission is not likely to be very exciting in the imaging. So far most of what has been returned looks more like the more ordinary images returned by the Mars Rovers. The real excitement of this mission is drilling for the water ice. The first images are look a whole lot like an old moon mission from the early sixties:

Phoenix is on Martian Ground

After the failure of the original mission, Mars Polar Lander… the Mars Phoenix Lander is confirmed on the ground and nearly right on the exact spot it was expected to land in. Next trick is opening the solar arrays and starting up all the instruments.

Mars Phoenix: May 25th Landing Site

Getting ready for the next Martian visitor!

This image is taken within the region that Mars Phoenix is expected to land on May 25th, one month from today. The whitish areas criss-crossing the landscape here is the seasonal carbon dioxide frost that covers the Martian poles during the winter. Phoenix will represent the first ever landing in a Martian polar region and is expected to yield considerably different results than we have seen from any of the previous landers or rovers.

Phobos as Seen by MRO

Phobos from MRO

This is a semi-false color image as explained on NASA’s site, “The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter took this image of the larger of Mars’ two moons, Phobos… on March 23, 2008. Taken from a distance of about 6,800 kilometers (about 4,200 miles). It is presented in color by combining data from the camera’s blue-green, red, and near-infrared channels”.

So there is some exaggeration of color here by including the infrared. I am guessing that is what is making the contrast between the reddish hues and those whitish marking at the edge of Stickney Crater. Click to see the hi-res… this may be the sharpest most detailed of Phobos I have seen yet.

Mars Hebes Chasma in Valles Marineris

I have been very busy lately… this is from the Mars Express site, “Hebes Chasma is an enclosed trough, almost 8000 m deep, in Valles Marineris, the Grand Canyon of Mars, where water is believed to have flowed. The High Resolution Stereo Camera (HRSC) on ESA’s Mars Express studied the area providing new pictorial clues to its history.”

Phobos in 5 Frames

Found these images of the Martian moon being tossed about like loose change on unmannedspaceflight.com last week. Don’t think I have ever seen any of these. They are from the ESA Mars Express mission currently in orbit around Mars.

Martian Avalanche!

Martian Avalanche Zoom Out

In the referential image above, two avalanches were captured in action by the Mars Reconnaissance Orbiter. The larger of these two (B) is around 180 meters wide, extends about 190 meters and the cliff heights are around 700 meters tall. The White material on the top that appears as snow is actually carbon dioxide frost which is currently receding as the Martian Spring moves closer. It is this very process which may be the cause of such falls as the carbon dioxide frost expands and contracts with the changing seasonal temperatures. Despite these seasonal changes, most areas of the Martian surface have likely been unchanged for millions of years, so it is quite rare to capture such cataclysmic activities in a single image from orbit.

Mars: Basal Unit and Dunes

A recent post on unmannedspaceflight.com inquired “What’s your favorite view of the poles?” and Philip Descarfino (who did the colorization work) responded with the above image. According to Philip, “I find this image one of the best of HiRise so far. You really get the feeling of staring off into the distance from just above the surface instead of looking directly downward. It’s mostly an illusion, but it works quite well in this image.”

NOTE: Technically the image itself is interpretive in that it is not an RGB composite but instead a colorized black and white image based upon other color images from the same region. Usually you can almost tell from a glance when this is done, but this one looks spot on.

Highlights for 2008

Titan on Jan 05, Feb 22, Mar 25, May 12 and May 28

Cassini takes a pass at Titan on February 22 (already having made a pass this year on January 5th).

Cassini Goes Plume Diving

Soon after Titan, Cassini performs a truly unexpected maneuver and flies directly through the plumes of Enceladus on March 12th. This is a somewhat risky task for the probe as the particles it will surely encounter may pose some kind of impact threat to the spacecraft. Mission planners expect the risk to be low as they intend to turn the spacecraft around and let the less delicate side of Cassini bear the brunt of the material and photograph the geysers as it moves away from Enceladus. It should make for some of the most exciting planetary science planned for this year.

Titan Alt

Cassini has another go at Titan on March 25.

Titan Alt

Yup – you guessed it. Cassini at Titan again on May 12th.

Phoenix on May 25

The Phoenix lander arrives at Mars on May 25th and (hopefully) makes good on the failure of the Mars Polar Lander. It will be the first time a probe will attempt a landing on the Martian pole and will conduct a series of experiments looking for the existence of water ice.

Titan Alt

You can never have too much of a good thing. Cassini at Titan again on May 28th as well as July 31.

Chandrayaan on April 9

Chandrayaan becomes India’s first planetary probe as it leaves for the moon in Early July (was April).

Cassini at Enceladus Aug 11, Oct 9 and Oct 31

The extended Cassini mission has made Enceladus a prime target of investigation and the new encounters begin on Aug 11th and comes within 54km of the surface.

Rosetta at 2867 Steins on Sept 5

Rosetta still on its way for an encounter with Comet 67P/Churyumov-Gerasimenko in 2014, will make a close pass at an asteroid named 2867 Steins on Sept 5th at a distance of only 1700 km. Steins is a small asteroid measuring only a few kilometers in size and the craft will be traveling at a relatively slow speed which should allow for some good resolution images to be acquired during the encounter.

Messenger on Jan 14 and Oct 6

Messenger (having just completed the first encounter in 33 years this past week) has another go at Mercury on Oct 6th and flies past more uncharted territory on its way to eventual orbit insertion in 2011.

Cassini Enceladus Alt

Two more close flybys of the Saturnian moon Enceladus on Oct 9 and Oct 31. The first at hair-raising distance of 25km and the second around a more reasonable 200km.

Lunar Recon Orbiter on Nov 3

In an effort to recognize the International Lunar Decade (and intended manned Lunar missions within 15 years), the United States returns to the moon with the Lunar Reconnaissance Orbiter on Nov 3rd. It is expected to begin its scientific goals only 3 days after launch and is expected to look for possible deposits of water ice in permanently shadowed craters near the Lunar poles.

Titan Alt

And finally more Titan flybys on Nov 3, Nov 19, Dec 5 and Dec 21.

All this is in addition to the ongoing work of Opportunity and Spirit on the surface of Mars. Mars Express and Mars Reconnaissance in orbit around Mars. Cassini’s non-targeted continuing tour of other icy Saturnian moons. And who knows, maybe we will see more than 2 or 3 reports coming from the ever quiet Venus Express mission currently at Venus.

Sadly, some very exciting missions will be quietly traveling en route to their targets and are not expected to be heard from in 08 like the Dawn Mission to the Asteroid Belt, New Horizons mission to Pluto/Charon, the newly re-targeted Deep Impact mission (now known as Epoxi) as well as Stardust now on its way to a follow-up visit to Tempel 1 the comet that was smacked by Deep Impact in 2005.
