The planetary society may be checking it out...

The Planetary Society has committed to raise the funds to preserve the priceless Pioneer data from destruction.


After years of analysis, but without a final conclusion, NASA, astonishingly, gave up trying to solve the "Pioneer Anomaly" and provided no funds to analyze the data. The Pioneer data exists on a few hundred ancient 7- and 9-track magnetic tapes, which can only be read on "antique" outdated computers. The agency is going to scrap, literally demolish, the only computers able to access and process that data in the next few months!

Could not the Pioneer tapes be saved on a more modern support, before scraping the computers which can read it? So far as we know there may be still valuable data to infer from them, especially with the affair of the "pioneer anomaly".

Much was already said about this anomaly:

-the gravitaion law working differently at great distance...
-effect of cosmological dark matter surrounding the sun...


or simpler:
-systematic mistakes somewhere into the measurement chain.


Perhaps the NASA and many scientists prefer the second set of explanations. But so long as the first set cannot be completely ruled out, the question remains open.
