First Images From Phoenix
Monday, May 26th, 2008This 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:
The horizon from Phoenix. You can now see the features that made up the cantaloupe-like texture of the images of this region from orbit.

Mars Phoenix: May 25th Landing Site
Friday, April 25th, 2008![]()
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
Wednesday, April 9th, 2008This 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.
Hebes Chasma in Valles Marineris
Wednesday, April 2nd, 2008I 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.”

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.
IMAGE NOTE: The images above are listed as RGB, but the accompanying text describes all the images as “false color”. Guess – maybe it means the colors are natural but exaggerated? See below for 1440×900 landscape wallpaper.
Mars: Basal Unit and Dunes
Saturday, March 1st, 2008A 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

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

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.

Cassini has another go at Titan on March 25.
![]()
Yup – you guessed it. Cassini at Titan again on May 12th.

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.

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

Chandrayaan becomes India’s first planetary probe as it leaves for the moon in Early July (was April).
![]()
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 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 (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.
![]()
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.
![]()
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.
![]()
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.
Unusual Stains on Mars
Thursday, December 13th, 2007The iPhone Set 01: Bodies of Major Interest
Friday, November 2nd, 2007If 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.
