I'm impressed you can see the coloured stripes on the parachute! HiRise just keeps amazing me.

Agreed. The latest shot is about the sharpest I've seen of all the landers, especially impressive is the red backshell and parachute with the lines clearly visible. You can clearly relate it to the ground view of the backshell. The lighting angle is excellent as well. Great stuff.

Thanks to slinted for sending me TIFF versions, much obliged.

Yeah, seeing the colored stripes is amazing. Also, you can see the lighter color at the center of the solar panels where there is more light-colored metal than dark-colored solar cells.

There is at least one more image of the landing site, taken 5 sols post-landing, but they don't have it on the release manifest, according to what I've been told. Fortunately the wait for PDS release is very short for HiRISE smile.gif

Will we be able to stack these images? Or are they taken from diffrent angles?

Could one of you post the (16 bit?) tiff crops somewhere?

Looks like as far as the chute stripes go, the most detail is in the blue-green image:

PSP_008855_2485_RED5_1.jpg:



PSP_008855_2485_IR11_1.jpg:



I guess that makes sense, as the stripes are red.

The above are crops from the EDR images (IMG), converted to JPG.

Speaking of different viewing angles, that's exactly what I am hoping for any pair of HiRISE images of the same target. Below is what results from making an anaglyph with the pre-landing image of the landingsite and the latest image with the hardware. North is up. The resolution is half of the normal HiRISE image. Added brightness and contrast.

Emily,

Looking at your blog, I found something very funny.
I first looked at the parachutte image and then sckroled down to "Buzzed by a binary" ...where the picture shown looks very much like the parachutte one with a poorest definition blink.gif

I noticed that too smile.gif It's especially funny because neither the subject nor the method of generating the images have anything whatsoever to do with each other.

Emily, thanks for posting/hosting them. I would have been happy to share them widely, but it might have melted lyle.org smile.gif

While we are all waiting for the TEGA team to catch a long deserved break, I thought I would post some of the work I have been doing. I have been playing around with a non linear focus/sharpen program. It goes in to recover high frequency information.

I used the Phoenix landing shot (22hours post EDL). The first image shows the top half processed and the bottom half in the original state. The sharpener/focuser separates the color image into 3 images (RGB) and processes them in isolation. Then I reconvert them back to a single 24bit color RGB.

I also zoom (3X) the lander. In the processed image you see that the shadow gap of the right hand solar collector has a better defined notch than in the original. I guess the next step would be to do identify real objects on the ground (from the SSI) to see if the resolution has been improved.

cheers

here is the zoomed lander from the original image but using the same zoom program.
(now you can actually compare them!)

I attempted to line up the HiRISE image with a vertically projected version of James Canvin's Peter Pan. I used the lander body as a reference, which was a bad idea, as the lander body is larger relative to the terrain than an orbital view would show since the camera has a perspective that cannot see terrain behind a solar panel or lander body. Still, some features are remarkably accurate. I attempted to match color and contrast as well. Anyone else who wants to try and make a better version can use the full vertical pan in the Peter Pan thread. Click to animate between the HiRISE and combined views. There are GIF posterization artifacts on the HiRISE view of the lander.
