Finally - I found an image of the Phoenix SSI with, I presume, two spare MER CCD's inside

http://www.lpi.usra.edu/meetings/lpsc2008/pdf/2156.pdf

It's sprouted a big lump on top of the white cylinder MPF and MPL design, due, I presume, to the use of two CCDs instead of one.

Oooohh...juicy info that only a true space enthusiast could love...

Decoding SSI filenames
Note that there's an indicator in the filename for whether the image is part of a mosaic or stereo observation (or both). Coool!

Et cetera...

And how the heck did I miss the fact that you were the lead for SSI, Mark? blink.gif

Is there anything you can tell us about the nominal plan for the pipeline for images? Peter Smith said at today's press briefing that "they will be made available on the Internet as they come down. You'll see them as I see them. We plan to operate the mission in an open manner." Which I had heard was true but it was very nice to hear him say that in the official context of the press briefing.

Can you hear that? That's the sound of me rubbing my hands and licking my lips -- I can't wait to see new data from a new spacecraft!

Also, in the downloadable version of the Phoenix clock, the index.html file gives the source code for converting to "Phoenix" time. Cool.

One question on the Phoenix filenames information: Is the spacecraft clock time interpreted the same way as MER's? Ie, "number of seconds since January 1, 2000 at 11:58:55.816 UTC".

Also, I could ask if there are any plans to release metadata, especially camera pointing information, for the images... but I don't want to bother Mark as we get into suspense time here.

Seems to be from 1980.0 (UTC).

In APG I handle the conversion from the system clock to Sol & Local time something like this:

#define SECSPERSOL 88775.244
#define PHX_SOL0 896166627//seconds since 1980.0
unsigned int uiSysClock,uiSol,uiH,uiM,uiS;
uiSol=(unsigned int) ((uiSysClock-PHX_SOL0)/SECSPERSOL);
uiSysClock=uiSysClock-(((unsigned int)uiSol*SECSPERSOL)+PHX_SOL0);
uiH=uiSysClock/3600;
uiSysClock=uiSysClock%3600;
uiM=uiSysClock/60;
uiS=uiSysClock%60;

I just figured this out from a variety of sources (and yes, the code could be a tad better optimized), but it seems to match the image products. One difference from MER is that the first Sol is Sol 0 for Phoenix as opposed to Sol 1.
