NIMA Locates The Mars Polar Lander 115
Skyshadow writes "Space.com is reporting that the National Imagery and Mapping Agency (NIMA) believes they've located the Mars Polar Lander, intact on it's landing legs. They've apparently had their people looking for the lander in photos taken by the Mars Global Surveyor, which has been tasked to take more photos of the landing area later this year."

The canals of Mars (Score:4)
That's OK; it's an honest mistake. An ironic one, too. Giovanni Schiaparelli (I would have never remembered his name; yay Google!) saw the optical illusion of lines criss-crossing Mars and called them "canali": a word that means "channels", but was mistranslated "canals". In English, "channels" generally means any fluid passage, but "canals" implies a water passage of artificial origin. So all the 19th century wonder about intelligent life on Mars was first sparked by an English mistranslation of someone else's language.
And doubly ironic, there are channels on Mars. They might be from lava flows instead of water, and they're much smaller than the optical illusions some squinting pre-Space Age astronomers saw, but they are there.

Disclaimer: I have no special knowledge in the areas of photo interpretation or geology, but to me there seem to be several common-sense reasons why good imagery doesn't give you all the answers.
Even if you had centimetre-resolution images of Mars, that's not necessarily going to tell you whether canals were formed by water. Why? Because it only shows what's there. It doesn't necessarily show you how it got to be that way.
Secondly, on Earth, you can use aerial imagery of well-known areas to learn what certain features look like, and then extrapolate to other areas. On Mars, we have (by comparison) bugger-all ground-based imagery, let alone extensive studies of geology and the like, to use to do extrapolation.

Yep. Actually, the bigger problem is that on Earth, we can observe features over time to determine how they are changing. There are geologic processes on Mars, but they will move glacially by comparison. We can't observe the Valles Marineris canyon system over time and see processes like erosion and sublimation, because they aren't happening -- or if they are, it's on a scale of tenths of a percent as fast as on Earth. So even observation over time is largely denied us as a tool.

Simple. You forget the camera resolution... with a surface resolution of only a metre or two, the entire lander would only take up one or two pixels at most, it may even be sub-pixel!
How do you look for something that small? You don't. What the NIMA guys are almost certainly doing is looking for the shadow of the lander! At certain lighting angles, the lander would cast a shadow 10s or even hundreds of metres across the surface.
NIMA looks for shadows, and estimates the size of the objects from the lighting angle. How do they tell if it's the lander and not a boulder, or if the lander is upright?
Come back later (like the scheduled observations in october?) when the lighting is at different angles, and take more pictures. From the way the shadow changes, you can guess the shape of the object, and if it's on the surface or a metre above it on legs.
The NIMA guys ovbiously have narrowed it down to a few likely candidates, and are waiting for more images.

These observers produced maps of the martian surface showing interconnected networks of canals, implying the presence of intelligent life on Mars. The intelligence which devised the canals was, however, on the terrestrial side of the telescope.

Seriously, it's called making theories based on observations. If you see a big rock with a big groove in the earth near it, you might conclude the rock was moved, say, by a glacier. On the other hand, if there's a nearby lava flow, maybe it was moved by volcanic processes.
That's a slightly silly example, but the point is that better data is really valuable. If anything, our experience correlating aerial views with ground views on earth provides a powerful reality check against our interpretations of mars photos from space.

The polar lander crashed. It was given up for dead. Have some respect for it.
There are several good reasons to find out if the lander really did crash as people had thought up until now, or if some other failure caused it to lose contact with NASA. Firstly, if it did land correctly, NASA would know that their design is sound, and they don't have to spend millions of dollars re-inventing a new landing system. They can just re-use the same technology from the polar lander. Secondly, if it lost contact for some other reason, surely it would be a good idea to find out what that reason is (to avoid wasting resources in creating a new lander that fails in exactly the same way).

It's mostly politics: JPL's Climate Orbiter failed, too, and JPL did one of the investigations into the two failures. Basically, they whitewashed their problems and crapped all over LockMart for what were very similar failings... not to excuse LockMart's bungling, just to point out another trait which NASA persistently exhibits.
If indeed the Young report's conclusions [space.com] were correct, a line of code in the system controller's program would fix the problem: basically, when the legs deploy they tend to set the switches which tell the vehicle it's landed, thereby shutting down the landing motors as soon as they ignite -- simply reseting the registers after leg deployment does the job. In this case, LockMart wants to fix the code, and wants NASA to launch it (well, at least some of the LockMart employees want this).
If NIMA has found the MPL as described, however, then something else is wrong and there's no point in launching another (possibly fundamentally-defective) spacecraft. The Young report was pretty scathing: both JPL's MCO and LockMart's MPL were built for less than the wildly-successful Pathfinder lander, and both projects suffered from lack of supervision by experienced planetary spacecraft engineers, and from inadequate testing. It's not clear that all the potential problems have been identified, so NASA's decision to cancel the 2001 lander's launch may be a good call -- I have mixed feelings about it.
But in any case, NIMA's "discovery" is extremely tentative (despite the ridiculously misleading headline (for shame, /.!), and I wouldn't base any decision on it at the moment. Something tells me that NASA won't launch it under any circumstances, especially given the Bush administration's attitudes toward NASA in general... more's the pity.

A world-class leader in imagery intelligence, NIMA routinely supports the operations of top-secret U.S. national security spacecraft. They employ specialists in maximizing information that can be gleaned from surveillance photography.
"Shortly after the loss of Mars Polar Lander, NIMA and NASA began working together analyzing images of the intended landing site and to try to locate the spacecraft," said Jennifer Lafley, a NIMA spokeswoman. "At this point, the results of this study are not conclusive, and the agencies are working together on resolving a number of technical questions," Lafley said.
NIMA experts believe they have identified the Mars Polar Lander. Furthermore, the source said that the lander appears intact on the surface, sitting atop its trio of landing legs.
