This image shows the high northern terrain on Titan. In the high north lie the large, dark features thought to be seas of liquid methane or ethane. Along the bottom of the image are Titan's equatorial dark regions, also thought to be seas -- but instead of liquid, they are seas of longitudinal dunes.

The view is toward terrain centred at 34 degrees north latitude on Titan. The image was taken with the Cassini spacecraft narrow-angle camera on March 29, 2007 at a distance of approximately 1.5 million kilometres from Titan. Image scale is 9 kilometres per pixel. Due to scattering of light by Titan's hazy atmosphere, the sizes of surface features that can be resolved are a few times larger than the actual pixel scale.
Cassini's radar eyes will image additional regions near Titan's north pole during an April 26, 2007, flyby. The instrument will image the area slightly north of an area nicknamed the "black sea." The radar coverage will cross over four previous radar swaths and begin to fill in more of the gaps in the coverage of Titan's north pole. On this flyby, Cassini's infrared spectrometer will see the lit and dark sides of Titan, looking for hot spots and lightning. The imaging cameras will do global mapping and full-disk mosaics.
The view looks toward Titan's northern hemisphere centred at 45 degrees north latitude. The image was taken with the Cassini spacecraft wide-angle camera using a spectral filter sensitive to wavelengths of infrared light centred at 939 nanometers.
Cassini¿s next Titan flyby on April 10, 2007, will bring the spacecraft over new parts of familiar terrain ¿ the Saturnian moon's north polar region. During this radar pass, more lakes or seas are expected to be visible. Among the new parts of familiar terrain to be imaged will be the other side boundary of the 'black sea', which could tell scientists more about its size. Additionally, the radar team has aligned this pass slightly southward so that it will align up with a future altimetry flyby planned for May 12.
