ESA released new set of HRSC images from orbits 1225 and 1863, which are map projected and radiometrically calibrated. At this moment you have to get them through the PSA interface
A color composite of a stripe of Meridiani Planum (includes Victoria) can be found here (2MB) |

A color composite of a stripe of Meridiani Planum (includes Victoria) can be found here (2MB) In fact, this is a 90deg rotated analglyph ( )... I'm not able to identify Victoria, even though there are many simil-Victoria crates... could you kindly show me where should be? -------------------- I always think before posting! - Marco -

Actually, it's just simple color composite - exactly same as in Oppy subforum. I know the color doesn't feel right somehow but it's not rotated. Look for the 3 big lined craters on the right about 3/4 down the image. Then in the lighter "rectangle" left of the topmost crater, is Victoria. Pixelwise it's [1180;15588] Or look at the Victoria crop for context

Perhaps not intentional, but channel shift around this crater (located at 1/5th of image height) is really 3D if rotated 90deg clockwise and seen through 3D glasses

As with the calibrated MER images, there are radiance offsets and factors that need to be applied to get each image into absolute units. They are in the PDS tags. Hilariously, in the map projected images, there are two tags for offset and two tags for scaling, labeled identically. They are significantly different in value, and there's no mention of which is actually supposed to be used...but by trial and error, I think it's the second of each that is appropriate to the map projected images (could be COMPLETELY wrong about this.)
Here's a couple simple image->RGB channel color versions, but with the scaling factors applied (not even close to true color, but a step in the right direction) The Meridiani image, thumbnail is rotated (left is south), full size has an arrow pointing at Victoria: And a crop of the full swath containing the water-ice crater on Vastitas Borealis I'm surprised they didn't mention the larger ice sheet north of the crater in their original releases. It is quite a sight. |

Thanks Nix, Doug!
Doug: classical interface, searching by orbit number, which works like a charm. Having just discovered these radiometric map projected images (thank you jaywee!!!), well, I'm in 'little kid meets candy store' land to say the least Here's another from much earlier in the mission. In the Water at Martian South Pole image release, we saw an OMEGA false color image, and a b/w closeup of the South polar cap. Here's that same area, in color (cropped, and at half res): |

The middle part of that huge 70k tall Gusev observation Looking around, it seems that a lot more nIR,G,B obs have been done than RGB. The HSRC doc says it has following filters: nadir, outer stereo (2), photometric (2) 675±90 nm; blue 440±45 nm; green 530±45 nm; red 750±20 nm; near-IR 970±45 nm. I'm struggling to find meridiani obs using lat long search - what parameters are you using? I used the coords from Google Mars: -1.95 354.47 |

1087, 1154, 1096 - all polar obs with nIR, G, B - perhaps the ice acts as an 'auto-level' thus making these look reasonable sans-radiometric-calibration
1201 just doesnt quite work out right - it needs that offset and scale processing I would imagine - and just for the sake of looking, I did the 1201 Super-Res channel mosaic as well. |

Nix: those first couple were just me looking up the orbit number mentioned in the press releases, I'm just getting a feel for the interface now as well...
babakm: that wasn't the most appropriate word choice on my part, but if we aren't laughing then we're probably crying. I see this glass as being half-full of data (which, for the ESA, is pretty good!) Doug: 1201, with the scaling factors applied, looks...cartoonishly orange. I'm seeing a lot of individual images that are coming out that color, with almost no chromatic range at all. I'm not sure if a: I'm misapplying these factors, b: the factors are wrong c: it really did look this red from a high phase or illumination angle, both of which would exacerbate the atmospheric filtering or d: the red filter (which is realistically a Near-IR filter itself, with its center outside of human vision) is a bad indication of visible red. |

Here's some interesting stuff....
A volcano ( I thought Ol.Mons but I have no idea to be honest - it isnt Ol Mons, a metaphorical cookie for whoever identifies it first ) from the HRSC, showing the coverage of the SRC - and then the SRC mosaic to match. Because this is a stereo camera, and because there are some serious elevation changes in this lot, you get slight channel miss-match in places - especially with high altitude clouds ( as with some of the polar images ) The HRSC colour image is at a best res of 102 m/pixel - the SRC 3.5m/pixel ( but I've downscaled, so 7m/pixel ) |

Actually - I'm going to pitch for more like 12...and I've not highlighted them but there's potentially another 2 in there as well, possibly more. I used Blue, Green and nIR for these...
Blue START_TIME = 2004-12-25T00:55:56.360Z Green START_TIME = 2004-12-25T00:55:37.866Z nIR START_TIME = 2004-12-25T00:55:04.547Z So - given that the red image is 'leading' the blue by 52 seconds, the full res is 89.5 m/pixel, and I'm getting between 6 and 9 pixels of motion between thsoe two frames...I'd estimate a speed of between 10 and 15 m/sec in a SE direction - one problem would be figuring out how much of that apparant motion is because of the slightly different p.o.v. between filters - but I think 10m/sec is a fair estimation. Look at me, getting all scientific Sadly - they didn't do all the filtes for this obs, but there's a normal red, and an ND filter obs that I've not looked at, so I'll try and do the maths with those later - see how well it ties in with 10-15m/sec Doug |

If I said what I really though, I'd end up banning myself from the forum, which would result in a quantum administrative black hole and the forum would vanish in a cloud of irony.
As a heads up - the ND3 filter is much much higher resolution than the colour filters - me thinks colour overlay on greyscale is in order. Doug |

Emily will have some goodies to show you in the not too distant future re: the Dust Devils in the White-Rocks image...but meanwhile - another Gusev observation, this time Orbit 637, and I've changed my channel-mixing technique. I find using Colour Balance just on mid-tones is very effective ( +53, -10, -15 for those interested )

Wonder if I squeeze a paper out of it?
ANyway - meanwhile, after noting that my martian geography is so bad I couldnt tell the difference between the north and south pole, I thought I'd play with something a little less...'dynamic'... Thats just about every Val Mar image I can find from the first 1250 orbits, I may have missed a few - but as you can see then tend to drop into 'batches' of similar observations from which I could probably generate some nice regional mosaics.

Doug,
I just can't stress enough how magnificent the DD animations you made are. I wonder if ESA knows what they have (Have you shown them to Jim Bell?) Anyway, as I said before - the archive is now available at http://pds-geosciences.wustl.edu/geodata/m...approjected-v1/ it's biggest advantage is easy accessibility of the thumbnail jpg images. Oddly, eventhough the ESA page says it covers 1-1863, it ends at 1295. Have you found data from newer orbits in the PSA interface? |

Yup - via the psa you can get to 1800andsomething
The browse JPG's are utterly perfect - they're exactly what was needed, and being able to just grab an orbits data instead of using the lengthy convoluted pain-in-the-backside PSA system is a big big BIG bonus - if you can catch up to 1863, it would be great. Doug |

I got a reply from the HRSC data processing manager, Dr. Thomas Roatsch, about some of the map-projected PDS/PSA tag issues, which seemed appropriate to share here.
As to the duplicate RADIANCE_OFFSET and RADIANCE_SCALING_FACTOR tags, the second ones are correct to the map projected images. For anyone particularly interested in the reflectance data, there is a necessary tag which is missing (REFLECTANCE_OFFSET). Dr. Roatsch has suggested to the PDS/PSA that they deliver a new version soon to fix both of these problems. When considering the radiance information recoverable by applying the offset and scaling factors, a third tag becomes important as well. The radiance values are in units of Watts/m^2/sr, and is not spectral radiance (Watts/m^2/sr/nm). This means that the calibrated radiance values in the images are a summation across the whole bandwidth of the filter+ccd. This is important because bandwidths of the HRSC color filters differ significantly. The red filter is 48 nm wide, green is 88 nm wide, and blue is 76 nm wide. In other words, if one didn't take this into consideration, the green filter would appear almost twice as 'bright' as the red filter, since its radiance is considered across a spectrum twice as wide. So, to recover spectral radiance from the HRSC map-projected images, one must apply the offset and scaling factors, then divide that value by the bandwidth of the filter. |

Here's one for you Phil,
Deimos has, to me at least, looked to be a much smoother almost 'softer' looking body than Phobos. Is that a symptom of the common images we see being of lower resolution, or an actual property difference between the two. Doug |

It's not a resolution effect. The best Viking images of Deimos have higher resolution that the best Viking images of Phobos. Deimos is smoother because it's almost completely covered by a thick debris layer. Peter Thomas (Cornell) has argued, and I agree, that the debris is ejecta from a crater with a diameter almost as large as Deimos's longest dimension, which is visible to us as the south polar "saddle" of Deimos. Most debris from a crater like that is ejected at very low velocity (forming the heaped-up rim of a lunar crater, plus lots of that never gets outside the crater at all) and coated Deimos at once. The rest was probably re-accreted from Mars orbit. Phobos lacks a "giant" crater of the same relative scale.

Here's the saddle:
Phil PS one of the most amazing views in the solar system would be had from the righthand hill here, looking across the 10 km wide saddle to the other hill, with Mars in the background surrounding that hill like a halo. -------------------- ... because the Solar System ain't gonna map itself.

I'm getting closer but not quite there yet. Maybe I should change my avatar to Deimos

Here's another image of Phobos from the PSA. It's not so hard to use once you get into it. I was misled slightly by the image size in the label, as I had to open this as a raw image in Photoshop, but once you remember to add the line prefix pixels to the width of the image it's OK.
Phil If you compare this with the last one, it's a mirror image. This is the ND2 image and it's reversed. The previous Phobos post was SR2, and it's right-reading. -------------------- ... because the Solar System ain't gonna map itself.

I'm getting closer but not quite there yet. Maybe I should change my avatar to Deimos I was going to use the latest Deimos image but I really prefer Phobos. Luckily, ugordan made a nice PNG image for me based on my favorite MOC image of Phobos. Hopefully, this should alleviate the bandwidth issues some were having loading my previous Phobos avatar, which was an offsite image at MSSS. |

Uh, oh. I hate to point it out but I can see a face in that image! Not so much on the thumbnail version as on the fullsize one. It kind of pops out there. (It's on the righthand side looking toward the right: two eyes--one round, the other sort of orientalish--a flat nose, and the lefthand cheek, a kind of sneer or grimace for a mouth.) Maybe you shouldn't have shown us that pic! Now we'll be hearing about The Face on Deimos and how NASA tried to hide it from us. ====== Stephen |

There are probably faces all over it. The first one I noticed is facing to the left and down. Big white lips at bottom of image, teardrop-shaped eye above, nose in profile flush with upper lip. In fact the whole thing seems to be a giant head sculpture obviously made by the Roswell people (who also influenced the Olmecs) . . .

Check out this abstract from the new EGU meeting: Greg Michaels on a new HRSC data viewer. Very promising. Also news of the release of HRSC-derived topography data.

Hey, come on people, give us some simple URLs! All that search stuff is unnecessary or should be hidden. Phil -------------------- ... because the Solar System ain't gonna map itself.

This is great to see Phil. I think NASA and the various PI's (notably MSSS, THEMIS, the MER/Athena teams and the HiRISE team, Cassini to a lesser extent) have really set a high standard for outreach and no doubt the ESA is feeling some heat for keeping its data so close. But that is not to in any way discourage them from this generous initiative.
