Did NASA give wrong pixel size for microscopic images of MER?
NASA said Mars Exploration Rovers (MER) Opportunity and Spirit take
microscopic images at 30 microns per pixel.
However, I often found that pixel size was about ten times too large
for many fossil cells/tissues discovered in the microscopic images
taken by the two MERs. One recent example is Figure 1:

In above Figure 1, I marked two complete osteons with Haversian
canals, lacunae,etc., but found they were ten times too large for
Earthly Haversian canals if I use the pixel size given by NASA.
Another example is Figure 2: http://www.wretch.cc/album/show.php?i=lin440315&b=20&f=1556215164&p=135
This discrepancy with reality has happened since day 1 of MER’s
landing on Mars. Something is terribly wrong.
Note 1: NASA recently made public many newly colorized microscopic
images taken by MER Opportunity, displayed at
