Cassini Images And The Pds, When ? Options

[Bjorn Jonsson]

Does anyone know when the Cassini images (including those of Jupiter) are scheduled to start appearing on the PDS ? Ages ago I read somewhere that the Jupiter images would be released a year after SOI. I wonder if some images of Saturn will be released then or not until late August (the start of Rev A) - it is now already well over a year since Cassini started imaging Saturn on a regular basis.

Good question.


Also was Venus also part of this image release?

Good question.


Also was Venus also part of this image release?

A line from the JPL RAW webpages has this:

This initial release of the web site includes data collected since May 14, 2004, but will eventually include the raw images Cassini has collected since the beginning of the mission.


But it's said that since July last year.

Here is the official line...

But as you will discover - neither of the interesting documents are available.

Might be worth an email - the PDS is usually quite repsonsive

I decided to email the PDS. Hopefully they'll reply.

There is a five year old version of "Cassini/Huygens Program: Archive Plan of Science Data" available here

It is the initial release version of this document, and was last updated in August of 2000.

According to the schedule listed in there, 3 cruise datasets, the SOI dataset, and the first regular submission (which seem occur once per Titan flyby) should have all been submitted by now.
I guess the timelines have changed. Hopefully we can find a newer version of the plan somewhere else that will give the updated timelines.

Apparently not in this case - three days since I emailed them and still no reply . And I'm pretty sure I emailed the correct address at the PDS Imaging Node.

[djellison]

Well - I got a great repsonse when I asked about MGS data releases a while back - so I will reply to that address about it.

I tried finding the email with all this info I could have sworn I had one with the PDS schedule...

Anyways, the first release, which covers all data from launch to SOI is on July 1. Each releases is 3 months after that, with releases coming every three months or so. The releases will come such that the last releases, cover the period to the end of the nominal mission, comes out three months after the end of the mission.

Some raw images are now available at this location:

http://pdsimg.jpl.nasa.gov/data/cassini/coiss_2001/

(I discovered this after downloading the entire collections of Viking Lander images).

Seems mostly calibration-related stuff but there are images there of Saturn and the rings that are helpful for figuring out the data format, PDS labels etc. (it looks like I'll have to make some modifications to my software to more easily handle Cassini images). I'm not sure this data is supposed to be 'official' yet though.

One rather frustrating discovery is that these PDS files do not contain any viewing geometry information.

Due date on the first of the month indicated

This should be quite a big release.

This should be quite a big release.

I think it's 11 DVDs. Fire up your computers!

[um3k]

When the images are finally released, will there be RAD images (or some equivalent) like they have with the MERs, or will we have to calibrate the images ourselves? And if we have to calibrate them ourselves, will there at least be software available that I can actually use to do so with?

[volcanopele]

I'm not sure. We have our own calibration software but I am not sure if that is being made available along with the PDS release. The guys who work on that software do read this board so maybe they can answer that. Unfortunately, I pay little attention to archiving when it comes up in telecons.
