Spirit's First Mars Images
An anonymous reader writes "First panoramic and overhead polar views of Mars, a quarter billion miles away are available. Some spectacular examples and accompanying commentaries are at NASA's Astrobiology Magazine, and JPL."
Details on the panoramic camera are available from Cornell. Check out the popup test image links which show the test shots they shot in the lab and at Cape Canaveral. They're pretty spectacular.

These are the real pictures: First Pictures. It should be noted that these are black and white and not color or false color, as the submitter may lead some to believe, to that magazine's tweaking of the original.
A blog like any other.
Here.
The pictures that have been released were taken by Spirit's Nav Cam, and at only 1/4th of the Nav Cam's maximum resolution. Remember, we weren't even expecting images at all yet. We were only able to take these because we only had a relatively small amount of time to transmit data (at 24 megabits per second). Larger images and color images from the Pan Cam will be coming by evening when Spirit's high gain antenna is directly in line with Earth. Then we'll have the bandwidth for the higer resolution (3 times the maximum resoultion of the Nav Cam, 12 times higher resolution than what we've seen so far) color images that the Pan Cam is capable of taking. It will probably take a few days to get an accurate full color panorama of the landing site.
There's loads of images here.
You are not alone. This is not normal. None of this is normal.
You are not seeing the curvature of the planet. You are seeing an effect of the wide angle lense that causes the picture to have a fish-eye like distortion.

It's almost certainly Sun CDE. CDE is (or at least was) used fairly extensively within NASA, and they have a great deal of Sun iron. For kicks, see this Google search which provides a bit of evidence as to the use of CDE within NASA. Note that the word "cosmic" has been excluded from the search, because NASA once had a project called "Cosmic Dust Experiment" or - you guessed it - CDE!
In any case, their environment is absolutely not Windows. Any number of choice quotes could be derived from this fact, not the least of which is, "When it's worth 400 million dollars, don't use Windows to keep track of it." If only the Fortune 500 were so savvy!
In case anybody wants to know what resolution the cameras will be taking the photos at you can get the whole technical specs for the pan cameras at

It's quite interesting actually. Real News for Nerds!
People keep commenting on the black and white quality of these pictures. AFAIK, these are lower resolution black and white photos taken for initial analysis to keep the file sizes low. The nice color pictures we all want to see should be here later today (around 12:00 P.M. PST 3:00 P.M. EST). Overall, i'm impressed that we have once again gotten something on Mars without unit conversion issues or just plain bad luck. Now it could only be topped if our President (or the next one) would announce a manned mission to mars challenge, similar to the one issued by Kennedy to go to the moon in the 60s.

According to another article on the same site HERE , the data transfer rate is exceeding their expectations 150% by sending "24 megabits per second" which certainly isn't broadband, but it ain't that bad either.
Paul Lenhart writes words!
Later on, they'll calibrate the camera using the color wheel on the sundial (yep another old technology that works ) and you'll get full color images that are very crisp. The color images will be composite images that are built from 3 separate shots of the same scene looking through different colored lenses.
Had they chosen instead to send a ccd that was wired like a digital camera, the images would have had 1/3rd the resolution they'll get this way.

The information in the article is incorrect. 24 Mbit (or 3 MBytes) of data were received in total over a couple of minutes at a speed of 128 kbps (This was for the first pass of the Odyssey orbiter). 128 kbps relates to the transmission speed from the orbiters to the Deep Space Network on Earth. That's not broadband, but it's not bad either, given the distance! The direct link from the rover to Earth will be much slower with around 12 kbps (but longer time periods of communication can be achieved each day compared to passes of the orbiters). However, this will only happen once the high-gain antenna is operable (which will probably be later today) and the Earth is visible from the rover.
All of the individual raw photos (which are clearer and in black & white) are available at:
