Another "radar view" from Titan: the "arrow"
|
Occorre la Caption NASA originale per tentare di capire qualcosa di questa "oscura" (da tutti i punti di vista) immagine radar di Titano: "...the (arrow-like) "feature" is approximately 30 Km across and it is formed from 2 straight lines that intersect. Looking more closely, one can distinguish other linear features that seem to follow the left side of the "arrow" and perhaps interact in some way with a dark spot. Straight lines may represent fractures or faults in the icy crust, or they may form from material that has flowed or has been shaped by wind, either recently or in the distant past.
The area shown is about 115 Km wide and 170 Km high and is located near 52° North latitude and 73° West longitude. This radar image is part of a larger strip of data acquired on Oct. 26, 2004, as Cassini passed Titan at a distance of 1.200 Km".
Secondo noi il rilievo che alla NASA chiamano "freccia" potrebbe essere una sorta di ciglio roccioso ma, come vedete Voi stessi, con un'immagine così...ogni ipotesi è buona!
