"Blood Stains" on Tethys: Evidence for Recent Activity?
Abstract
A distinctive set of arcuate,reddish-colored lineaments has been identified on Tethys. These markings are slightly darker than adjacent cratered terrains but have a flatter green -IR spectral slope. The lineaments form an arcuate pattern centered on the tidal axis with Saturn. High-resolution image data show only the faintest traces of surface distortions, collocated with small,low-albedo spots <1 km in diameter. One possibility is that these markings may be nascent fractures, accompanied by relatively reddish discoloration from venting and deposition of material from the interior.
