East Limb View of Earth’s Moon as Seen by the Clementine Spacecraft
Caption:
About 50,000 Clementine images were processed to produce the four orthographic views of the Moon. Images
PIA00302
,
PIA00303
,
PIA00304
, and
PIA00305
show albedo variations (normalized brightness or reflectivity) of the surface at a wavelength of 750 nm (just longward of visible red). The image projection is centered at 0 degree latitude and 90 degrees longitude. The dark albedo features Mare Smythii (image center) and Mare Marginis (above Smythii) are just visible from Earth on the extreme eastern edge of the lunar nearside. Maria Crisium (directly west of Marginis) and Mare Fecuditatis (southwest of Crisium) are familiar nearside features as seen from Earth. Maria regions are believed to be large basins formed by impacts from cosmic projectiles later filled by basaltic lava flows from volcanic eruptions. Basaltic lava flows on the basin floors give maria their dark albedo appearance.
