Cassini Spies Bright Features in Kraken Mare Possibly Related to “Magic Island” Observed in Ligeia Mare

Space scientists think could be floating debris or waves on the seas of Saturn’s moon Titan

Space news (November 18, 2014) – Sailing over Titan’s moons – 

Cassini sailed over Saturn’s moon Titan on August 21, 2014, to take a first look at the depths near the opening of a huge river valley along the eastern shore of Titan’s largest sea Kraken Mare. NASA space scientists collected data along a 120-mile shore-to-shore track of the hydrocarbon sea. One part of this track collected altimetry data along a 25-mile section indicating sea depths in this region of 66 to 115 feet (20 – 35 meters). This involves Cassini’s radar bouncing a beam off the bottom of Kraken Mare to determine an estimate of the depth in the region.

During this 25-mile section of the 120-mile track across Kraken Mare Cassini’s radar and Infrared Mapping Spectrometer (VIMS) detected bright features in the sea space scientists think could be similar to another bright, mystery feature previously observed in another of Titan’s seas, Ligeia Mare, researchers have called “Magic Island”. Detecting the features using both instruments gives scientists a better look and idea of the identity of these enigmatic features.

Space scientists at this time think these unknown features observed by Cassini’s instruments could be waves, floating debris or something else entirely. Unfortunately, it may be awhile before we know anything more about the bright features observed in Kraken Mare since this is the last chance for the spacecraft to observed the region.

Cassini will fly by Titan once again in January 2015, to take a closer look at the original feature spied in Ligeia Mare. At this time they’ll also attempt to measure the sea depth of Punga Mare, the only large sea in Titan’s far north Cassini hasn’t observed.
