Can someone help me get oriented here? I've always been fascinated by the Caloris Basin, and I'm looking forward to seeing it in more detail during the fly-by. So...

Attached Image


1. Have I labelled its location correctly in the top image (view pre-closest encounter)?

2. Where will Caloris Basin be on the images of Mercury we see post closest encounter? (if we're going to see it at all?)

Over to our magnificent map makers... smile.gif

n00b question -

How does a spacecraft like Messenger slew back and forth rhythmically as in this video? Does that targeting use propellant or can gyros or something else produce that motion?

Or should I go search through the comments on the death of the scanning platform thread?

Stu,

Check out the screenshot I've culled from the following animation:

The Caloris basin (or half of it) is visible inside the green circle. Messenger will have a good look at it on the outbound leg of the encounter.

This will give a rather poor, high-sun-angle view of Caloris on the limb. Some basin ring relief may be visible on the limb. Color differences will be more visible than near the terminator, complementing the mariner 10 terminator data and some indications of chemical differences of the smooth and fractured plains filling the basin from ejecta, etc.

Great explanation by Noam Izenberg about what will be the work done by MASCS and how this will occur.

MESSENGER Team Receives First Optical Navigation Images

But don't get your hopes up; as far as I can tell, the news release doesn't actually include the images huh.gif

EDIT: I've confirmed with the project that they don't plan to release the images until tomorrow's press conference.

We have an happy team over there...Ralph McNutt words:
"We have a beautiful crescent of Mercury centered in the imager field of view!"

He's teasing us...isn't he?... smile.gif

I know that at least one of the MESSENGER team has been lurking here for a while, so I'd just like to wish everyone involved with MESSENGER all the best for the fly-by next week.

Looking forward to those first images! smile.gif
