The Center for Earth and Planetary Studies is a scientific research unit within the Smithsonian’s National Air and Space Museum. Established in 1973, CEPS studies the geology and geophysics of planets and satellites using spacecraft data, laboratory analysis, field analogs, mapping, and remote-sensing techniques. It also operates a NASA-supported regional planetary image facility.

Its researchers work on Mars, the Moon, Venus, Mercury, icy satellites, and terrestrial processes that help explain other worlds. Areas of expertise include impact cratering, volcanism, geomorphology, radar imaging and sounding, surface–atmosphere interactions, and geologic mapping. Staff participate in missions and instrument teams rather than functioning only as museum curators. CEPS staff have served on teams for missions including Mars Reconnaissance Orbiter, Curiosity, Europa Clipper, and Venus investigations. Their work with NASA data includes geological maps that become reference products for other researchers. Radar expertise is particularly useful for separating surface structure from effects introduced by wavelength, viewing geometry, and processing.

CEPS is relevant to questions about unusual imagery, planetary features, and life beyond Earth because it can place observations in geologic and instrumental context. The center is not a UAP investigation office, and an unexplained image feature is not evidence of an artificial structure until acquisition, processing, scale, and natural alternatives have been examined.

The center connects public museum collections with active planetary science. A CEPS attribution gains meaning through the responsible researcher, mission, dataset, and published conclusion. Those details separate institutional scholarship from an unsupported appeal to “the Smithsonian” and connect a striking image with its scientific interpretation.
