Some think the 1971 Mars-3 lander, launched by the USSR may have been found by the NASA MRO.
"Russian space enthusiasts poring through photos from NASA's Mars Reconnaissance Orbiter have spotted what looks like the remains of the Soviet Mars 3 lander that arrived at the Red Planet in 1971.
The Soviet Union lander was the first spacecraft to survive a Mars landing long enough to transmit data back to Earth. However, after transmitting for just 14.5 seconds after landing on Dec. 2, 1971, Mars 3 went dark for unknown reasons."

The accompanying picture with this story does show some objects on the surface of Mars, but what they are is unknown at this point in time.
The Russians have contacted NASA's MRO Team and requested HiRISE images, which NASA has done. Further pictures of the site are planned.
If this is true, it is an in creditable find.
