Catena Albufeda

The word "catena" is a Latin term defined by the International Astronomical Union to indicate a chain of small craters. A catena can have several origins, one of which is endogenous, it refers to volcanic activities along lines, where small eruptions occurred underground. As much as small catenas are still classified as collapse well chains related to volcanic activity, it is believed that most lunar catenas indicate the rebound points expelled by larger shocks. Some may indicate points where the Moon was hit by an object from space that broke before impact, as is often the case with comets.

A very significant chain of craters is the catena Abulfeda, shown in the photo. The Abulfeda catena, also known as "Abulfeda Crater Chain", is a crater chain approximately 210 km long. The four largest reference craters in the photo are; Abulfeda (on the right, 65 km), Almanon ( near the center, 49 km), Geber (at the bottom left, 44 km), and Tacitus (at the bottom right, 41 km) In 1976, the Abulfeda crater was named after the 14th century Kurdish historian Ismael Abul- fida.

We can easily see the Descartes crater, which is located just above, in the upper right corner of the Abulfeda crater. The Descartes A crater is located next to the right edge of the Abulfeda crater. A section of the outer edge of Descartes is covered by a region that has an albedo higher than the surrounding surface. It is worth mentioning that approximately 50 kilometers north of this crater was the landing site for Apollo 16. The irregular region around the landing area is sometimes called the Descartes Plateau or the Descartes Mountains.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
