Station Cassini took a picture of an unusual canyon on Saturn's satellite Tethys. As reported on the NASA website, Ithaca Canyon stretches for two thousand kilometers, that is, it occupies three quarters of the circumference of Tethys.

The depth of the canyon varies from three to five kilometers, and its width is about 100 kilometers. In places the canyon rises to a height of 0.5 kilometers.

Cassini took a picture on January 30, 2017, when the station was at a distance of 356 thousand kilometers from Tethys.

The space station Cassini-Huygens, worth more than three billion dollars, was launched into space in 1997 to study Saturn and its satellite Titan.

Cassini is named after the Italian scientist Jean Domenico Cassini, who proved that the ring of Saturn consists of two parts, separated by a dark strip (Cassini division) also assuming that the rings of Saturn consist of parts of various sizes.

Cassini-Huygens - one of the most ambitious space stations ever launched into space.

It is filled with a huge number of instruments and cameras for accurate measurements and high quality images in different atmospheric conditions and color spectrum. The space station consists of the Cassini orbital station (built by NASA) and the probe Huygens (European Space Agency).

Cassini's mission is a joint project of NASA, ESA (European Space Agency) and the Italian Space Agency.

One of the achievements of NASA scientists exploring photos with Cassini is the detection of liquid water in the depths of Titan. Also earlier, NASA published unprecedentedly clear photos of Saturn's rings.
