Mars

The Red Planet

Mars Animation of December 17th
This animation of Mars was made with 6 different RGB sets taken on the night of December 17 in good seeing conditions (8/10). The total time spawn is 20 minutes during the transit of the planet at the meridian.

Mars on December 17, 2022
This image of Mars was taken on the night of December 17 in good seeing conditions (8/10), with the planet transiting the meridian. At the left of the globe is visible the Sinus Meridiani ("meridian bay") with the characteristic double hook shape, the dark region on Mars originally chosen as the position of the prime Martian meridian by the first observers of the past charting the planet. The brighter large central area is "Arabia Terra", a mountainous region in the north of Mars, densely cratered and heavily eroded, presumably one of the oldest terrains on the planet. To the right of the globe is one of the most distinctive dark areas on the surface of the Mars, named Syrtis Major, extending approximately 1,500 km (930 miles) north of the equator and 1,000 km (620 miles) west to east. Below of it, in the southern hemisphere of the planet, lighter in color, is the huge, roughly circular basin named "Hellas" . This is the third largest known impact crater in the Solar System.

Mars on December 10, 2022
This image of Mars was taken in a brief moment of clear sky on the night of December 10 in medium-good seeing conditions (7/10), with the planet having just passed the meridian. From my observation site the Valles Marineris, the long network of canyons visible as a dark branching structure to the left, is starting to move toward sunset giving way to new features like Mare Erythraeum and Niliacus Lacus (respectively the dark areas below and above the center of the globe). The former is a very large dark and dark region of Mars whose name comes from the Latin Mare Eritreo, because it was originally thought to be a large sea of liquid water. To the right of the globe, the Sinus Meridiani ("Meridian Bay") is about to enter the scene with the characteristic double hook shape, an albedo feature on Mars originally chosen as the location of its prime meridian when the great observers of the past began to chart their observations of the planet.

Mars on December 05, 2022
This image of Mars was taken on the night of December 5, 2022 with mediocre seeing conditions (5/10). The dark branched structure visible in the center of the planet is the Valles Marineris, a system of canyons that runs more than 4,000 km (2,500 mi) along the Martian surface. Valles Marineris is the second largest canyons of the Solar System, surpassed in length only by the rift valleys of the mid-ocean ridge system of Earth. Just right of the canyons is Xanthe Terra, a large area centered just north of the Martian equator. Below and to the left of Valles Marineris is Solis Lacus, a dark feature on Mars once called "Oculus" and is still called "The Eye of Mars" because of its resemblance of a human pupil.
