Schiller Crater

Another lunar image (the one on the left) acquired last Friday evening from Melbourne, Australia.

The Schiller crater is an unusually elongate impact structure (179 x 71 km in dimension) near the southwest edge of the moon, surrounded by Rost, Weigel, Bayer and Noggerath and their respective smaller adjacent craters. Schiller formed either by the merging of two craters, or alternatively it is a single elongate crater formed from an oblique grazing impact. Schiller is 3900 metres deep on it's northwest side, such high-relief features are common on the lunar surface where there is no water-cycle to erode the surface.

Schiller is also the site of a dramatic close-up image by LROC (Lunar Reconnaissance Orbital Camera) that imaged a ~9m wide boulder and the track where it rolled down the side of one of the hills at the southeast end of Schiller, and while it looks recent, is potentially up to 50-100 million years old, likely dislodged by an adjacent impact, with it's track overprinted by several smaller craters.

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.
