I've had a go at cropping & enlargening some MESSENGER images from the outgoing part of last month's encounter.
Very interesting. I have reposted all images as the first ones were so healivy compressed that they were hard to look at. Andrew Brown.

A few more cropped & enlarged images from the outbound part of the MESSENGER encounter.
The smoothish plains are very interesting, volcanism after the main impact era was over. I have reposted all images below, as the first ones were so badly compressed, that were awful to look at. My originals are very sharp indeed, shame I cannot put them here. Andrew Brown.

Just seeing those pictures is amazing. I just feel this frission- yeah, I think that's the word.

Thanks KaiYeves.
I reposted them as the first ones I put on were compressed too far (didn't realise that I could post higher capacity images). I have thoroughly enjoyed the Mercury encounter & it is about time that we get full global coverage of Mercury, seeing as sometimes, it is the second closest major natural body after the Moon (when Venus & Mars are not aligned with Earth). It is a thought that Mars has had many landers & orbiters (rightly so really) & Venus too (though not so many as Mars), but Mercury has had none, only the historic Mariner 10 encounters that saw only 45% in detail. MESSENGER is going a long way to right that wrong. Mercury has so much to tell us about the evolution of the inner solar system & offers rare insights to out own Earth (very similar density & abundance of heavy metals). My hope was that JAXA would scrap its orbiter to accompany BepiColombo, but instead provide a companion Lander, equipped with PanCams & a seismometer. I think Mercury is a most fascinating planet that has been neglected for far too long. MESSENGER has proven last month that she is more than up to the task of revealing Mercury in a whole new way. Excellent stuff.  The only change to MESSENGER's mission in my opinion, is no changes to the spacecraft herself, spacecraft is perfect for the mission, but make the Hermeocentric orbit circular & lower than what it will be. I find it strange that Apoherm will be at 15,000 KM approx ober the southern hemisphere & that many longitudes will not be imaged at high resolution. I feel that is a great shame, the entire planet should receive the same high resolution coverage. Feel as though the current planned orbit is a bit of a missed oportunity.  A few more images here. I will be back with more. Andrew Brown.

Yes that one I cropped from the Narrow Angle Camera MESSENGER North Polar View of Mercury. It shows a few large craters with interconncting valleys, all flooded with basaltic lava, when cooled & solidified, does look like swampy terrain. Appearances like this are most deceptive.  But it was at one time liquid (molten rock) filling in the lower lying terrain (crater floors & valleys).It is observations like that, that will be able to reveal much about the Hermeology (Geology) of the first rock from the Sun & further refine the Hermeological events in sequence. I have a few more crops & enlargements here. The first one is a 100 KM wide crater on the newly imaged terrain, the others are inbound (on previously Mariner 10 imaged terrain) around the Mattisse, Sholem Aleichem & Sullivan Craters. The smoother lava plains are still quite interesting. Andrew Brown.

Hi Tricky Woo,
Yes, soon we will get to see some new views in October. Today's update: Dark haloed craters. Below my crop & enlargement of the featured 100 KM wide crater with dark ejecta. Andrew Brown.

A couple of images I have worked on.
Cropped from yesterday's update. 1). 300 KM wide area of lava plain. 2). Two 80 KM wide craters, eastern one terraces & with dark halo. Andrew Brown.

Today's Update.
Craters on N W Rim of Caloris Basin. Images I have worked on from today's update. 1). 60 & 70 KM wide craters. The 70 KM wide crater has a dark halo, wheres the 60 KM wide crater has a mottled floor. 2). Hills on the N W rim of the Caloris Basin. Perhaps created from impact melt from the Caloris Basin impact event? Andrew Brown.

Sorry if this is kind of a noob question, but how do they keep the probe from getting fried by the radiation near Mercury? Isn't their considerably more of it there than there is farther out in the solar system?
Similarly, does all of the radiation make it more difficult to communicate with the probe or to track it?

 I don't think the radiation is enough to fry the spacecraft directly, just overheat it if precautions hadn't been taken. And communications isn't a big issue so long as the spacecraft isn't in the same direction from Earth as the Sun (which is an issue for all the planetary spacecraft, not just this one.)

Yes that's it. During the recent encounter & the one coming up in October, MESSENGER & Mercury were / will be receiving approx 11.1 KW per sq metre, some nine times that, the Earth gets. So overheating is a bigger issue than hard radiation. Andrew Brown.

I hope we get to see the full size NAC frames in this MESSENGER approach mosaic.

Hi m1omg,
Mariner 10 did a superb job, considering the primitive technology compared to what we have now. MESSENGER will be absolutely fine, I am not worried, but of course, with something like MESSENGER, Phoenix (your avatar), Cassini, etc, these missions are so important to us, that we hate to see anything screw up. Latest update from MESSENGER. Making a mosaic 2. Andrew Brown.

The enigmatic spider pattern is now known as Parthenon Fossae. The crater itself is named Apollodorus, after a Greek architect from Damascus who was probably the designer of the Parthenon.
