Titan Images 2019
The image above, obtained during the Cassini
mission in the Saturn System which started in 2004 and which ended in
2017, reveals a portion of Titan's atmosphere which appears completely
opaque from outer space in the visible spectrum. One can notice, in
particular, the detached haze layer evolving in the upper atmosphere of
Saturn's largest moon. That thin layer appears purple in this colorized
view and the color is close to what the human eye would see from outer
space. The original image was acquired with the Narrow-Angle Camera of the
Cassini orbiter on July 3, 2004, one day after the first flyby of Titan.
The view was captured at a distance of approximately 789,000 kilometers or
491,000 miles from the giant moon and at a Sun-Titan-probe, or phase,
angle of 114 degrees. The image was obtained on the basis of a spectral
filter sensitive to wavelengths of ultraviolet radiation centered at 338

The mosaic in the upper part of this table, generated on the basis of data obtained from the Huygens probe during its atmospheric plunge performed on January 14, 2005, unveils an aerial view of Titan's surface. One can notice, in particular, a remarkable contrast between a dark plain and brigh hills composed of a network of dark channels. Does the dark plain correspond to an ancient sea ? Does the plain undergo flooding events from time to time ? The dark channels are likely drainage channels or rivers. They may be closely related to meteorology or rainfall events involving liquid methane. The mosaic in the lower part of this table represents a colorized image of the upper view.

The view above reveals a mosaic of images
of Saturn's largest moon Titan in the infrared spectrum. Each disk of the
Opaque Moon Titan unveils surface features thanks to the infrared eye of
the Cassini spacecraft whose mission in the Saturn System started in 2004
and ended in 2017. The colors of each disk are artificial and are mainly
based on data obtained from the Cassini spacecraft and from the Huygens
probe during its remarkable atmospheric descent on January 14, 2005. In
the visible spectrum, the surface of Titan can't be discerned from outer
space due to the hazy atmosphere of the giant moon but in the infrared
spectrum, one can clearly see surface features and a major contrast
between relatively bright areas and relatively dark areas.

The image appearing in the upper part of this table represents a raw image of Saturn's largest moon Titan obtained on July 2, 2006 from the Cassini orbiter. The file name of the view is W00015711.jpg. The camera of the probe mobilized the CB3 and CL2 filters to acquire the raw image. The view had not been validated and calibrated at the time of the image release. A validated/calibrated view had to be archived with the Planetary Data System of NASA. The image appearing in the lower part of this table represents a colorized view of the upper view. One can notice surface features in the disk of Titan. The contrast between relatively bright areas and relatively dark areas on the Opaque Moon appears well pronounced.
