This is a Maya stone carving from Palenque, Chiapas, Mexico. After careful review, many believe it is a detailed representation of a space vehicle- with many recognizable parallels to our own space shuttle, such as the position of the astronaut. While stylized, many see clear depiction of antenna, flight direction system, turbo compressor, control panel, tanks, combustion chamber, turbine, and exhaust. Mayan Astronaut Mayan Astronaut
As a former field investigator for MUFON, I think this is great coverage! Thank-you on behalf of the rest of the population.
