Cassini Spacecraft Checks Out Titan’s Figure

NASA/JPL Cassini Titan FlybyToday in the journal Science, astronomers have released data and information derived from the Cassini spacecraft related to the detailed shape and size of Saturn’s moon Titan. Remember that Titan has a thick atmosphere, in fact it’s one bar, or the same atmospheric pressure as exists on the surface of the Earth at sea level. It’s surface is completely obscured from optical observations, so these results combine visible images with special radar images called synthetic aperture radar (SAR). Using these data, astronomers can conclude that Titan has some oblateness, that is, it has an equatorial bulge.
