New Tethys Image: Tethys Mysteries

Today's image of the day from CICLOPS is another view of Tethys, this time a crescent view from May 22, a couple of days after yesterday's daily release image. This view shows the region between Ithaca Chasma and Odysseus impact basin. Ithaca Chasma can be seen near the limb near 4 o'clock. The heavily crater region (the two large craters near the terminator at center are Mentor at north and Circe at south) also boasts a dark stripe that runs from Ithaca Chasma back to Odysseus. The exact nature of this stripe is currently unknown, though frequent reader Phil Stooke has proposed that the stripe is a cryoclastic deposit from geysers along Ithaca Chasma.
