Not from the website directly. For the arm animation I made earlier I sorted the JSON entries on the spacecraft clock time which is given as "extended/sclk". (and can also be found as part of the image filename)

Does anybody know this plate's purpose?



Here are some other pictures:

It's a 'Bellypan' that protected the Adaptive Caching Assembly (ACA) since launch, but especially during the final part of EDL...

Surface operations on Mars require the Sample Handling Assembly (SHA) to extend approximately 200 mm (~8 inches) below the Rover’s bellypan. Therefore, an ejectable belly-pan was implemented directly below the Adaptive Caching Assembly (ACA) volume, which was released after landing to provide the SHA with an unobstructed volume to extend into during operations. Surface features are then assessed via Rover imaging prior to SHA motion to prevent contact with potential obstacles below the Rover.

Thanks!

FYI this event is discussed in the regular thread:
http://www.unmannedspaceflight.com/index.p...=8608&st=60

I think this thread here is supposed to be focused on imagery, e.g. technical discussion of processing, cameras, metadata etc.

ADMIN: Chris is correct. Let's please post mission event pictures such as the panel deployment in the real-time progress threads (Perseverance Early Drives being the current one) and reserve this thread for technical discussion of the imagery systems and methods.

After I installed the required plugins,how to perform batch debayer in ImageJ and GIMP software?

Need an installation script, right? How to do it?

I use FitsWork to debayer images. It's great!

Can it be processed in batches? How to do it?

use the command-line interface to your tool (if it has one) and a batch file.

I get it, it's great!

Yeah,I get it, it's great!

Do you have any insight into the MET portion of the filename. When did MET start (ie. when was it zero?)

At the moment its around 0669527872.

I would like to rename some of the raw images in the order they were taken and where pairs were taken keep those together - I think they would be taken at about the same MET anyway so sorting by MET should work to keep stereo pairs together.

MET seems to have been wrong on some images, or at least, the MET is the time the image was uploaded by the spacecraft rather than the time it was taken by the camera. Especially the EDL images. Or have they fixed that now?

Thanks!

The sclk (mission time) filename (and json) field appears to start on Jan 1st, 2000 - see here. And yeah, that field is still incorrect on at least some EDL camera images.

0 is 2000-001T11:58:55.816 ("epoch of J2000" in Coordinated Universal Time.)

This then drifts as a function of rover clock rate and is tracked by the NAIF file that Fred linked to, so you need to use the NAIF function scs2e or something like that to get a usable time. https://naif.jpl.nasa.gov/pub/naif/toolkit_...C/req/sclk.html

Hope this is the right thread for this question?

The SHERLOC imager is said to be a direct build to print version of the MAHLI imager on MSL. With MAHLI images the focus motor count is provided on the raw image server, using that count enables users to approximate the distance and scale of 'close-up' / 'in-focus' MAHLI images.

The SHERLOC images returned so far don't appear to have a motor count on the raw image server (that I can find)

Is the SHERLOC motor count provided on an image JSON feed somewhere? Any pointers would be appreciated, as I'd hope to check it's my use of the count using targets like the PIXL calibration target where its exact size is known. Then I can use it for scaling the geological targets in the future. TIA
