That means the ESA images are all mud! Make-believe stuff based on some 3D imaging software! So what are NASA and ESA up to? Billion dollar probes
with million dollar cameras on board just to see shoddy pics generated by some 3D software? Is this what our great scientists base their analyses on?
Was this the way imagery was planned to be got from those probes and processed as false CGIs?
I would like to point that the type of
photos that are taken by those missions are those that the scientists want (I hope

), not what the common people want, that is why they usually use
the red filter as the primary filter and never use a RGB filter, they use separate filters, and the case of HiRISE they do not even have a Red, a
Green and a Blue filter they have a combined Green+Blue one.
The 3D images are just a small (and not the most important) part of the data gathered by the 7 instruments:
- the High Resolution Stereo Camera (HRSC), with near infrared, red, green, blue, nadir, forward, backward and two photometry channels
- the OMEGA Visible and Infrared Mineralogical Mapping Spectrometer (used to analyze the surface composition)
- the SPICAM Ultraviolet and Infrared Atmospheric Spectrometer (uses the light from the stars that are seen through the atmosphere to look for Ozone
and water vapour)
- the Planetary Fourier Spectrometer (this uses the Sun light to analyze the reaction of the molecules on the atmosphere)
- the ASPERA Energetic Neutral Atoms Analyser (analyzes the effect of the Solar wind on the Mars atmosphere)
- the Mars Radio Science Experiment (MaRS) (uses the radio communications with Earth to analyze Mars' ionosphere)
- and the MARSIS Sub-Surface Sounding Radar Altimeter
With all this data available, 3D images are the less important.
PS: the camera was already developed, it was an adaptation from the original camera built for the failed Russian Mars-96 mission, so it was cheaper,
the Russians had already paid for it.
