I know Ralph was trying to plug non-imaging data but I would have thought that the simplest way to track the sun would be to have a small camera pointing at a sundial.

Well I 'm hoping we'll see a release soon. It's been a month since HiRISE looked at us!

Is that not Endurance, with Erebus half cut off at the bottom?

Isn't this a job for HiRISE? They were able to point it at the Earth not long ago so why not Holmes. Should be able to get some decent resolution unlike most cameras out there.

Dust contamination? I was about to say what a pleasure it is to work with Spirit and her nice [relatively] clean lenses for a change.

Although I was also going to say what a right pain it is trying to process full resolution 360 degree panoramas using a P3 with 256Mb RAM, but that's all I have at the moment and at least it made me track down a few memory leaks.

Enjoy,

As soon as it's down and I have the time I expect I will, should be spectacular.

Aaagh! too much to do

J

Thanks for the heads up.

More information, inc finding chart here.

Now if only these dam clouds would lift.

For some unknown reason my dust flatfield doesn't seem to work on the right-most image so this isn't very good, but anyway...

Cape Verde - Sol 1329.

Actually my comment did come from Doug talking about it in the first video.

But I admit, I did then go, "Oooh Doug has some more videos" and watched parafoil tests and Gizmo.

Well, New Zealand - similar but with fewer rings.

I've found that thread now so i can catch up - silly me thinking that that there wouldn't be any images from the flyby yet, being that it's still the same year. #

Wow! Maybe I missed it - But I hadn't seen the stunning Philae image of Mars+Rosetta before!

Good show Doug.

Parafoils - Genius!

Coming back to the camera pointing issue that you talked about. With two cameras, I'm as torn as you are about having one landscape and one portrait vs both in portrait. I don't think there is a lot in it, and determining which is best is probably rather dependent on how much the gondola is swinging. At the moment I think I'm inclined to go with the 'double portrait' mode to, as you say, maximize the coverage from horizon to nadir. A slight clarification from what you said, you probably don't want to mount them to get from horizon to nadir in one shot, we really want to be getting the horizon in as much as possible. So the first should probably be mounted so that the image centre is pointed somewhat at the horizon (maybe a little below). Hence the bottom edge of the lower camera will be at 60-65 degrees, hopefully low enough so that with a few fortuitous swings we get some direct nadir imaging.

If you can do the tests on the field of view and get an idea of what frame rate we can manage (power, memory), I'll examine some images from other projects to try to get some better statistics on the expected gondola motion and then I'll run some more simulations.


Oh, and about mixing units - I now know who I'll be blaming when we loose it on EDL!

"Shark's Tooth Ridge" Sol 1344

Sol 1299 'Ingress Survey Right' - Looking back up to the entry point.



James

I think the tracking database needs a kick, even with light activity we would still expect to see a few sequences (like Tau) and lots of data is coming down so there doesn't appear to be any problems with Oppy herself.

Still a little more of the site 3 360 degree panorama to come down, but the L7 is all here.

This is just a quick test of the stitch really, so there is a lot of contrast mismatch, but I thought I'd post it to give you lot a quick preview.



James

A couple more mosaics.

Some old images coming down today.

This one caught my eye (lifted straight out of MMB):



You can see a reflection of the pancam/navcam bar silhouetted against the bright dusty sky.

And to start taking entries for the compulsory 'fly your name to...'

Sols 1305 to 1319 - L257 - Looking along the bright band.



James

Hurrah.

Just found out that I've won the second prize (Mars poster) last week.

I don't know how useful this is as I play a few tricks deep within my processing software, but this is my input flat-field:



I gave up using the sky-flats as well, the stretching does bad things I think. This is made from some fairly featureless ground pointing pancams in L1 from sol 1290 stacked and blurred. Properly used it should account for vignetting as well.

James

It certainly is.

Better late than never, here are my attempts at the 1294 ingress survey.



James

I'm going to wait for the missing data for that one i think.

Here is the view on the other side on the same sol. L7 only at this stage, I'll drop in the colour when it arrives.
