Rosetta Mars Flyby, Info and Links Options

[Ron Hobbs]

It is so amazing, the views you see on this forum. I had not seen the perspective looking out over Charitum Montes before.

From the google translation, "The picture shows such HRSC profile of the Martian atmosphere from December 18, 2004, recorded during the Mars Express orbit 1176." They were apparently planning to do joint observations of the atmosphere with Rosetta during the flyby. Has anyone done anything with those HRSC observations.

Gerald, did you do the colorization?

Yes, here a jpg-version using filters 88, 83, 84 for red green, blue, respectively, no cleaning or other post-processing (edit: ok, rotated 90°, like the previous stereo), colors as provided by the single channel jpg images:

You'll find the original images here and here, used in this article.
Both images have been taken by the High Resolution Stereo Camera (HRSC) of Mars Express.

Thanks, Gerald. Hmm, I see it's still only in German! Either way, amazing images. I had no idea they existed until last night.

That's a try to translate the caption of one of the images; a translation of the whole article is maybe a little too much to post:

With the stereo camera HRSC onboard the ESA mission Mars Express not just highly-resolved 3D image data of the red planet can be taken, but also the profile of the Martian atmosphere, when looking against the curved Martian horizon. Several such HRSC takes are planned for the hours of the Rosetta Mars fly-by during the second half of February 24, and during the first half of February 25; almost at the same time the camera system OSIRIS will record image data. The profiles of the Martian atmosphere acquired under several angles allow conclusions for the scattering behaviour of the aerosols in the atmosphere. The image shows such an HRSC profile of the Martian atmosphere of December 18, 2004, taken during Mars Express Orbit #1176. The vertical structure of the atmosphere lets discern a lower, denser layer of about 16.4 km thickness, which is covered by wafer-thin layers of haze, which reach up to about 25 km height. The horizon is located at about 66 degrees southern lattitude, close to the south-polar terminator and is 2,535 kilometers away, north is up in the image, the image resolution over there is about 100 meters per pixel. In the upper half of the image the shallow interior of the Argyre impact basin can be seen, which is bordered by the Charitum Montes below (southward), which rise up about six thousand meters above the Argyre plane. Right top at the eastearn border of Argyre half of the 230 kilometers-wide impact crater Galle can be discerned.

Oh, thank you once again for that.

Does anyone have a source for these two images? I've looked through the thread and the links they originally came from seem to be dynamic and have updated to an unrelated item in a language I do not speak. I gather that they have something to do with Mars Express. A friend posted the link directly to the attachment at this forum, which surprised me... and he got it from his friend so it looks like it may or may not now be viral and I have zero info on it!

Last year I worked with those images as I had plan to make very high definition animation from this sequence.
Because my work on this animation is now postponed I upload at least reduced version here.
But still even reduced version is in full HD (1080p).
