That would be great, Fred. We have found some touchdown points by trial and error for the Saturn V and LM, but they definitely need some fine tuning as the vehicles will sometimes tip over when changing views or during time acceleration. Your input we be greatly appreciated!

Here are a few early samplers of what keeps me busy at the moment: incorporating the Mars Express HRSC (high resolution stereo camera) data into the Mars elevation and surface textures.

For the surface textures I am currently only using the panchromatic images from the HRSC nadir camera. These have been used to pan-sharpen the artificially colourized MOC (Mars Orbiter camera) data that are used as a colour reference. The next step will be to incorporate the HRSC colour channels as well.

MOC (Orbiter 2016)


MOC+HRSC (current development status)


MOC (Orbiter 2016)


MOC+HRSC (current development status)


Generating the mosaics from the individual HRSC fragments is a fairly elaborate number-crunching effort because of the sheer amount of data. Once I've tested the final processing pipeline it will probably have to run for a couple of weeks to generate the global map. I hope it's going to be worth it ...

Orbiter 2016 is reaching the threshold of not being able to tell screenshot from photo.

If the result looks anywhere near to those screenshots, then I'd say yes, it's gonna be worth it. I have tried to describe the two posted screenshots without using expletives, and failed miserably.

Do you have the necessary hardware freely available? Donation efforts for orbiter don't make much sense in most cases, but a few guys putting some money together to rent an amazon EC2 server for a month or two so you don't have to block your own hardware with such a process would sound like a sensible thing.

Thanks for the offer. I should be ok though. I can probably quietly use I slightly underused machine at work (128GB RAM, 32 cores, my favourite Linux box ). The problem with sharing out the workload is distributing the data. I've got about 1.5TB of HRSC source data at the moment, and that's only the level-4 processed images. If I decide to also include level-3 to improve coverage, it will be much more. And it wouldn't be trivial to partition the data into local chunks.

Oh yes. Especially depending on the overlaps of the different sensors.

Holy... How large is that final texture archive going to be?

Also, just made the "litmus test" with my wife. She totally thought that screenshot was an actual photograph of Mars.
