Scarface Petavius (Guillermo Gonzalez)

Scarface Petavius

Acquisition type: Lucky imaging

Another image from the summer nights, this time with some images put together in a mosaic around Petavius. One of the complex craters with high terraced walls (towering up to "himalayang walls of almost 3.3 km) above the crater floor.

In the image and with the existing light there are several features worth mentioning:

It can be seen some of the evidences of the heavily modified by post-impact volcanism processes. Very clearly, the "first" one of the Rimae Petavius, with an inner third of its lengths about 4 kilometres wide, but then it narrows to about 2 kilometres and becomes deeper as it approaches the outer wall. There are a number of small dome-like hills on either side of this cleft.

Fairly central lies a large central, mountainous massif with multiple peaks, climbing 1.7 kilometers above the floor.

Snellius is the large crater, 83 km in diameter, lying south west of Petavius. The crater is located in the centre of Vallis Snellius, which runs across Snellius from northwest to southeast. The individual craters that combine to form Vallis Snellius (south of Petavius) are already heavily eroded. Vallis Snellius is orientated radially to the centre of Mare Imbrium, with its overall length of around 590 km, is one of the longest lunar valleys on the nearside.

Stevinus crater, 75 km in diameter, southwest of snellius, has a central peak, which looks beautifully clear under this light.

Last but not least, as it is very prominent on this image, it is the "railway", on the southwestern part of the rim of Petavius, there is this peculiar double ridge, rather long (150 kilometres long) which passes through Petavius C and ends at craters Hase (not visible in this image).

Happy to share it & hope you like it

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.
