Cassini
catches a pit twosome on Saturn's moon Dione that is superimposed on more
established, straight components. The upper of the pair, named Italus, is
overprinted on a gathering of antiquated troughs called Petelia Fossae. The
lower pit, Caieta, sits on a component named Helorus Fossa. Researchers are
certain that Helorus and elements like it are extremely old, both in light of
the fact that there are numerous old pits on top of it and as a result of the
way that material has evidently filled in the shallow valley, giving its edges
a gentler appearance. Fossae on Dione (698 miles or 1,123 kilometers over) like
Helorus are accepted to be tectonic elements, shaped when the territory between
tectonic flaws drops down into trough-such as structures. This perspective is
focused on territory at 22 degrees south scope, 73 degrees west longitude. The
picture was brought in obvious light with the Cassini rocket limited point
camera on Sept. 30, 2015. The perspective was gotten at a separation of
approximately 25,000 miles (41,000 kilometers) from Dione and at a
Sun-Dione-shuttle, or stage, point of 64 degrees. Picture scale is 804 feet
(245 meters) per pixel. /Nasa.Gov orginal post/
