While I was doing that, I noticed that the frames from their animation seemed to have been processed a bit to bring out more detail than is instantly visible in the individual frames as previously released.

Yeah, looks like they performed deconvolution on previous frames as well. Turned out nice - after all, they're the ones who know NAC PSF best.

I just received a cryptic comment from a MESSENGER worker I've been exchanging emails with, to the effect that "the flyby was even more successful than early indications (while the media were there) - stay tuned."

Tease!

Hopefully there's a nice fat belt of mountains on the equator of the unmapped hemisphere. wink.gif

Hmmm... To what effect more successful?! Only thing they have up until now is a beacon signal. Surely they couldn't have attempted a radio occultation with the weak signal and actually found out something useful?

Those teasers!

Early reports suggested that the C/A point ended up being a little further away from Mercury. Perhaps, after deconvolving their Doppler data, they determined they were almost spot on.

Any idea how much farther away? It's a longshot, but what are the chances they managed to squeeze a short, "undocumented" burst of high rate telemetry between Earth occultation end and solar occulation end?

Not sure. The Reuters article on the flyby mentioned that C/A altitude was slightly higher than expected (again perhaps this wasn't the case):

JRehling said: "... time for last-minute predictions. I'll stick my neck out and predict that there will be no major surprises. The unseen side (about 1/3 of which we'll see on the outbound view) will have a big basin (Skinakas) similar to Caloris,..."

I will stick my neck out and say Skinikas doesn't exist. It's just a random patch with fewer ray craters.

My hope is that they found some sort of unexpected terrain. Or a moon. Not likely, but given the quality of radar coverage, Mariner 10 limb coverage, and the gaps that exist, there would be places for unusual features to hide, particularly if they are not very big. I know that some have interpreted the feature I posted (my stacked 3rd encounter Mariner-10 view) feature, dubbed "Discovery Dome," as an old volcanic dome. Granted, the moon has plenty of nice domes too, but perhaps better examples were found. Anyhow, I will quit my wild speculating for now.

Just home from work; glad to see that everything went so well!!! smile.gif smile.gif

Speculation...I'm with Ted on cinder cones, but would love to see the blasted remnants of an ancient shield volcano...of course, that couldn't be the surprise that Emily alluded to.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Ummm... if CA was appreciably different from planned, doesn't that have a fairly significant effect on the trajectory?

By the way a strange faint dot can be seen in the last aproach image. Artifact, star or even MOON?
