The Search for Extraterrestrial Intelligence (SETI) has a low probability of success, but it would have a high impact if successful.
Physicists Paul Davies and Robert Wagner of Arizona State University argued last year that it makes sense to widen the search to scour the Moon for possible alien artifacts. At Penn State, researchers propose the same type of search for Mars. To date, SETI has been dominated by the paradigm of seeking deliberately beamed radio messages.
The ASU team argued that Alien civilizations may have sent probes to our region of the galaxy, and that any mission to the solar system would probably have occurred a very long time ago. The lunar environment could preserve artifacts for millions of years due to the absence of erosion and plate tectonics.
Elswhere, two researchers at Penn State, are asking "why have we never found evidence of other civilizations in Solar System?" The team is approached the problem mathematically, which shows that we have not looked in enough places to ensure that no extraterrestrial artifacts exist in our solar system.
Even without actual contact, like us, other civilizations could be sending unpiloted probes to quietly peek at our civilization. These probes, like ours, would be small and might be hidden in a variety of places. In the asteroid belt they would probably go unnoticed, especially if these nonterrestrial objects are only 3 to 33 feet in size, weighing little more than a ton similar to our Voyager craft.
"Extraterrestrial artifacts may exist in the solar system without our knowledge simply because we have not yet searched sufficiently," said Haqq-Misra and Kopparapu. "Few if any of the attempts would be capable of detecting a 1 to 10 meter (3 to 33 foot) probe."
The moon and Mars have been searched to a small extent. An ongoing mapping project, the Lunar Reconnaissance Orbiter, is looking at the moon at a resolution of about 20 inches, so we may eventually be able to determine if there are no nonterrestrial objects on the moon. The researchers caution that surface maps may not be sufficient to distinguish between a space probe and a rock.
MastCam:
This system will provide multiple spectra and true color imaging with two cameras.[54] The cameras can take true color images at 1600×1200 pixels and up to 10 frames per second hardware-compressed, high-definition video at 720p (1280×720).
Mars Hand Lens Imager (MAHLI):
This system consists of a camera mounted to a robotic arm on the rover, used to acquire microscopic images of rock and soil. MAHLI can take true color images at 1600×1200 pixels with a resolution as high as 14.5 micrometers per pixel.
MSL Mars Descent Imager (MARDI):
During the descent to the Martian surface, MARDI will take color images at 1600×1200 pixels with a 1.3-millisecond exposure time starting at distances of about 3.7 km to near 5 meters from the ground and will take images at a rate of 5 frames per second for about 2 minutes.[56][66] MARDI has a pixel scale of 1.5 meters at 2 km to 1.5 millimeters at 2 meters and has a 90-degree circular field of view. MARDI will have 8 GB of internal buffer memory which is capable of storing over 4,000 raw images. MARDI imaging will allow the mapping of surrounding terrain and the location of landing.
Can you provide links to Google Mars and Google Moon?
They don't exist yet. But maybe if these physicists get their way, they will.
Note: These should not be used for serious research.

Look here for the Moon and here for Mars.
They may not be as flashy as Google's, but they have direct links to the original high resolution photos.
10k a year for annual membership fee?!
Um, what the hell is up with that?!

And, if I may ask, where are all of the tens of thosands of images--yep, that many--of Phobos.
Probably because they do not even exist.
...Not available to mere mortals that's where.

Nor will they ever. Any cartographic application will alter the original data. If you find something of interest, get its latitude and longitude and go to the source images.
