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 The Pioneer data exists on a few hundred ancient 7- and 9-track magnetic tapes, which can only be read on "antique" outdated computers.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.

My prefered non-standard explanation would be that a small amount of dark matter would be linked to the solar system, creating a gravitationnal field which would peak at the distance of Jupiter or Saturn, decrease in 1/r2 beyond, and be null around Earth, because we would be inside this mass. If dark matter is formed of material weakly interacting particules, they still obey to gravitation, and thus they must be in orbit around the galaxy, at speeds in the 200/300km/s range. So it is expectable that some were caugh by the solar system and may orbit around it. This said, I think we can seriously consider such kind of extraordinary hypothesis only after correct examination of all the existing data, and eliminating all the causes linked to the probe, solar wind, etc. Especially each hypothesis will have its own recognizable profile. |
