The planetary society may be checking it out... QUOTE 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 The Pioneer data exists on a few hundred ancient 7- and 9-track magnetic tapes, which can only be read on "antique" outdated computers.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! |

If you've got new scientist...there's an article about the pioneer anomaly:
http://www.newscientist.com/article/mg19025541.800.html I haven't actually read it, but maybe someone can tell us what it's about |

Oh, and the tracking data being used this time is for a much longer time period than previous analyses used.

Oh, and the tracking data being used this time is for a much longer time period than previous analyses used. Bob Shaw Anderson & company had trouble mapping solar wind acceleration coefficients for both Gemini and Galileo-They ended up adding an additional term that varied by ~1/r at a magnitude much greater than the Pioneer anomaly. Since this factor held an exactly solar vector, it is impossible to differentiate the 'unexpected force' from an unexpected attenuation in the solar wind. (Which could be as simple as deionization over time and distance.) If the bulk of the Pioneer data leads to a similar conclusion, the next step may be something to give us a better feel for the solar wind...Something like the Planetary Society's solar sail |
