Good stuff Andrew! I'm assuming the are combining HIRISE and Shallow Subsurface Radar information for each potential landing site.

3488 · Jun 6, 2007

Hi portercc, Common sense would dictate probing any potential landing site. I have heard nothing of the SHARON results on board MRO. I think that they will be extremely careful. The landing site areas I posted, will shortly be entering the bitter cold of the Martian Winter. Soon, the observations made of the area of the failed Mars Polar Lander should be due. Will be good to see if it did land safely & did not talk for some reason, or it crashed!!!

I would like to see them merge the data into a single image. I don't see them taking any risks with this mission. My name is on the MPL too.

July 20, 2007 Mars Reconnaissance Orbiter Mission Status: Engineers are gathering and analyzing engineering data to understand the cause of a software error between NASA's Mars Reconnaissance Orbiter and one of its instruments. That event, on July 17, caused the spacecraft to turn off two of its science instruments--the Mars Climate Sounder and Compact Reconnaissance Imaging Spectrometer for Mars. The team expects to begin bringing the spacecraft and instruments back to normal operations on Friday, July 20, with normal science operations expected to resume early next week. The spacecraft itself remains healthy and its other science instruments are functioning normally. From JPL website.

I have looked through a lot of HiRISE images, but these are the oddest dunes I've seen yet. Very complex, linear dunes with 'combs'. Some of them are terminated by 'dove' like features. I don't know much about dunes but these might be the result of the wind direction changing a lot. Perhaps it has something to do with the elevation differences to the north and west of the dune field causing turbulence and eddies in the air flow. <div class="Discussion_UserSignature"> </div>

From the MRO JPL website. News Releases Mars Reconnaissance Orbiter Status Report: Camera Concern Resolved; More Than 3,000 Images Returned August 24, 2007 Diagnostic tests and months of stable, successful operation have resolved concerns raised early this year about long-term prospects for the powerful telescopic camera on NASA's Mars Reconnaissance Orbiter. The High Resolution Imaging Science Experiment (HiRISE) camera on the orbiter has now taken more than 3,000 images of Mars, resolving features as small as a desk in targeted areas covering thousands of square miles of the Martian surface. Already, this is the largest Mars data set ever acquired by a single experiment. The camera is one of six instruments on the orbiter. During the first three months after the orbiter's primary science phase began in November, researchers saw an increase in noise and pixel dropouts in data from seven of the camera's 14 detectors. The effects on image quality were small in all but two detectors, but the trend raised concerns noted in a February, 7 news release . Tests have yielded an explanation for the earlier pattern, and the camera's performance record shows the noise stopped getting worse after about three to four months of the science phase. Alfred McEwen of the University of Arizona, Tucson, principal investigator for the camera, said, "I'm happy to report that there has been no detectable degradation over the past five months." A team at Ball Aerospace & Technologies Corp., Boulder, Colo., designer and builder of the instrument, has used an engineering model of the camera's focal-plane system to successfully duplicate the problem. This has helped in understanding causes and in testing a procedure for warming the focal-plane electronics prior to each image. One cause is that an elect <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Some parts of Mars are the pits <img src="/images/icons/wink.gif" /> The High Resolution Imaging Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter has confirmed that a dark pit seen on Mars in an earlier HiRISE image really is a vertical shaft that cuts through lava flow on the flank of the Arsia Mons volcano. Such pits form on similar volcanoes in Hawaii and are called "pit craters." This view, a small portion of a HiRISE image taken on Aug. 9, 2007, shows a dark pit about 150 meters (492 feet) in diameter set in a lava flow. The image was taken with the camera pointing slightly westward, instead of straight down. It catches the eastern wall of the pit lit by afternoon sunlight. The image was taken at 2:34 p.m. local Mars time. The full HiRISE image that includes this view is online at http://hirise.lpl.arizona.edu/PSP_004847_1745 Credit: NASA/JPL-Caltech/University of Arizona /safety_wrapper> <div class="Discussion_UserSignature"> I'm a recovering optimist - things could be better. </div>
