Planetary SETI
Planetary SETI is concerned with the search for extraterrestrial structures on the surface of bodies in the solar system. Claims for evidence of extraterrestrial artifacts can be divided into three groups, the Moon, Mars, and the other planets and their satellites.
Examples of sites of interest include the "bridge" sighted in the Mare Crisium in 1953, and the "Blair Cuspids" sighted in 1966. In 2006, Ian Crawford proposed that a search for alien artifacts be conducted on the Moon.
Percival Lowell's mistaken identification of Martian canals was an early attempt to detect and study an alien culture from its supposed physical remains. More recently, there was interest in the supposed Face on Mars.
The Society for Planetary SETI Research is a loose organization of researchers interested in this field. The organization does not endorse any particular conclusions drawn by its members on particular sites.

Famous quotes containing the word planetary:
“We cannot cheat on DNA. We cannot get round photosynthesis. We cannot say I am not going to give a damn about phytoplankton. All these tiny mechanisms provide the preconditions of our planetary life. To say we do not care is to say in the most literal sense that “we choose death.””
—Barbara Ward (1914–1981)
