The Soviet probe Phobos 2 sent 38 photographs of the surface of Mars, some showing strange shadows. On 25 March 1989, pointing to the satellite Phobos, the probe took a last snapshot (left), in which the satellite can be seen together with a very elongated cylindrical object, whose shape coincided with one of the shadows. Marina Popovich, a colonel in the Soviet Air Force, showed this photograph at a press conference (right) at the USSR consulate in San Francisco in 1991. (Associated Press - The New York Times)
