PHX + HiRISE Options

[djellison]

There have been, as far as I can find, 8 HiRISE obs of PHX released to the HiRISE website at full res (i.e. not 2x2 binned)

Of those, 5 are really quite good, 3 are not so great.

So I've overlaid the interesting parts to see any changes. The parachute folds over a bit at some point between Aug 23rd and Sept 19th - other than that, nothing really to see.

The different observing angles are very very obvious when you look at the back-shell on its side. Have a go at convincing yourself you can see changed in the arm work-volume. I couldn't quite see anything.

I'm not sure what's going on with HiRISE. Looking at Opportunity and Spirit - the earliest images are the best. But there ARE images AS good as that in each months updates. PHX is an odd-ball because of low light angle, thus having to crank things up to get an image.

The first images released of the landing sites were stunning. But subsequent images from HiRISE show a lot of noise and banding.

Without going into the actual image and lighting geometry now, I'd venture a guess that's just a result of poor illumination and really marginal signal to noise ratio. No doubt detectors degrade over time, but this would be radical.
