To bad the NASA scientists, or upper brass, skipped the final testing, which would have found the spherical aberration error, prior to liftoff. 

It would have been interesting to see the photos, if it didn't have the corrective optical elements.

So why does NASA change past data values, particularly on temperature records? And how does one know if one is adding more errors to the data, when they don't know when, & how, the original data was taken.
