Title
False-Color Lunar Image
Full Description
This false-color photograph is a composite of 15 images of the
Moon taken through three color filters by the Galileo
spacecraft’s solid-state imaging system during the spacecraft’s
passage through the Earth-Moon system on December 8, 1992. When
this view was obtained, the spacecraft was 425,000 kilometers
(262,000 miles) from the Moon and 69,000 kilometers (43,000
miles) from Earth.
The false-color processing used to create this lunar image is
helpful for interpreting the surface soil composition. Areas
appearing red generally correspond to the lunar highlands, while
blue to orange shades indicate the ancient volcanic lava flow of
a mare, or lunar sea. Bluer mare areas contain more titanium
than do the orange regions. Mare Tranquillitatis, seen as a deep
blue patch on the right, is richer in titanium than mare
Serenitatis, a slightly smaller circular area immediately
adjacent to the upper left o Mare Tranquillitatis. Blue and
orange areas covering much of the left side of the Moon in this
view represent many separate lava flows in Oceanus Procellarum.
The small purple areas found near the center are pyroclastic
deposits formed by explosive volcanic eruptions. The fresh
crater Tycho, with a diameter of 85 kilometers (53 miles), is
prominent at the bottom of the photograph, where part of the moon
disk is missing.
