ESA releases images taken by BepiColombo during Mercury fly-by

The European Space Agency (ESA) yesterday released images taken by the BepiColombo probe as it completed its fourth fly-by of Mercury on its long journey to enter orbit around that planet.
The picture to the right, cropped, reduced, and sharpened to post here, was taken four minutes after the closest approach of about 103 miles.
Four minutes after closest approach, a large ‘peak ring basin’ came into BepiColombo’s view. These mysterious craters – created by powerful asteroid or comet impacts and measuring about 130–330 km across – are called peak rings basins after the inner ring of peaks on an otherwise flattish floor.
This large crater is Vivaldi, after the famous Italian composer Antonio Vivaldi (1678–1741). It measures 210 km across, and because BepiColombo saw it so close to the sunrise line, its landscape is beautifully emphasised by shadow. There is a visible gap in the ring of peaks, where more recent lava flows have entered and flooded the crater.
BepiColombo still has two more fly-bys of Mercury to do before entering orbit in November 2026. At that time the spacecraft’s two orbiters, one from Europe and the other from Japan, will separate and take up complementary orbits.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

Although pretty pock-marked, there are regions in the picture that appear fairly crater free, and with what seems mountainous terrain, rather than smooth plains one would expect from volcanic events…
I admit to having almost no knowledge about Mercury, other than it is mostly metallic core, but given that it is at the bottom of our solar systems gravity well I would expect more craters.
Is the surface churned up by many, many small impacts, or is something else at work here? Any links or knowledge much appreciated!
Lee S: Um, why don’t do what I do to start, do a search on BtB for “Mercury.” In my posts I always link to my sources, so the data mine will be deep.
