See: http://www.msss.com/newhome.html Perhaps the best place to start "peeking" or exploring is at: http://www.msss.com/moc_gallery/narrowangles.html This presents a flat "mars" global image and one can pick a section, and then pick a "turquoise colored" dot or swath. At the moment, one of the most unusal photos is at: http://www.msss.com/moc_gallery/images/M0306104.html There one will see the MOC narrow-angle image M03-06104 on the left, and MOC red wide-angle context image M0306105, which shows the broad area, and high lights the area shown on the left image. Under the MOC narrow-angle image M03-06104 are photo "blow up" options, under "lossey JPEG, GIF, IMG, IMQ. This area also shows longitude, latitude etc, further down on the page. I prefer the JPEG images myself but I guess it doesn't really matter for simple viewing. I've tried to save GIF, and photo chop, but I got too many color errors, so I used JPEG on my web site. Judging from the MOC red wide-angle context image M03-06105 it would appear (via simple color texture), that alot of the area, has the rough same texture, this implys speculation that the same kind of view is rather common. Lacking more follow-up images (yet), of course it can't be verified immediately. The Mars Global Surveyor camera doesn't seem to be steerable from the satellite from what I've heard from others. The percentage of narrow-angle photos is very small compared to the land area, and so, areas of high interest may take many years to completely cover, or even add on to areas of higher interest. They have some 27,500 photos on the site at the moment, truly a massive giant byte collection. Even the one line per shot index takes up some ~ 13 meg, for the moment. Its really just a fun deal to see the images, if one has some spare time to explore whats there. More speculations says that there is likely alot more images with some startling visual impact. However, I think for one person, they could go on virtually forever and not see everything, then too, they add more every day....ha.
