Shrouded in a thick atmosphere, the surface of
Saturn's largest moon, Titan,
is really hard to see.
Small particles suspended in Titan's upper atmosphere cause an almost
impenetrable haze, strongly scattering light at visible wavelengths
and hiding surface features from prying eyes.
Still, Titan's
surface is better imaged at
infrared wavelengths, where
scattering is weaker and atmospheric absorption is reduced.
Arrayed around this visible light image (center) of Titan are
some of the clearest global infrared views of the
tantalizing moon so far.
In false color,
the six
panels present a consistent processing of 13 years of
infrared image data from the
Visual and Infrared Mapping Spectrometer (VIMS) on board
the
Cassini spacecraft orbiting Saturn from 2004 to 2017.
They offer a stunning comparison with Cassini's visible light view.
NASA's revolutionary
rotorcraft
mission to Titan's surface is due to launch no earlier than July, 2028.
