Chief O'Brien, who is also the role model for Chuck Norris, sits on a makeshift raft, legs half in water, is looking at his torn pants and says in dismay: "I don't believe it!"

Kanalizasyon deyince acaba 2014 mü dedim, öyleymiş. O zamanlar İznik'e çekime gitmiştim, her yer delik deşikti. Neyse ki arazi aracı kullanıyorum.

Huygens, too...😊
View of Titan's surface, as seen from the camera of Huygens lander. It looks like a dry lake bed with various size of pebbles. General colour is orange, because of the methane haze in the atmosphere of Titan.

APOD 79
2 Worlds, 2 Analemmas
apod.nasa.gov/apod/ap25062...

The Martian analemma was presented by @elakdawalla.bsky.social‬ here:
www.planetary.org/articles/a-m...
...Meanwhile, I had put together the Earth version while I was working in Baku, Azerbaijan:

The figure-8 shaped curve you get when you mark the position of the Sun in Earth's sky at the same time each day over one year is called an analemma, as seen in the left hand panel from Baku, Azerbaijan. Shape of the analemma depends on the eccentricity of a planet's orbit and the tilt of its rotation axis, so analemma curves can look different for different worlds. Mars' axial tilt is similar to Earth's, but its orbit around the Sun is more eccentric. As seen by Opportunity rover from Victoria crater in Mars, the analemma traced in the right hand panel is shaped more like a tear drop. Each world's solstices lie at the top and bottom of their respective analemmas.
