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 The Pioneer data exists on a few hundred ancient 7- and 9-track magnetic tapes, which can only be read on "antique" outdated computers.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

Thanks jamescanvin for the image and the info it contains.
What would be fine is if somebody have the log-log plot, amplitude versus frequency, with expected domain for each gravitationnal wave source, and the expected sensitivity of each instrument. What I heard (to check) is that the LIGO gravitational wave observatory is curently reaching its full sensitivity, but it still detected nothing (the only thing it could detect, neutron stars spiraling, would happen only once a year in average). |

Yes, that was what I was looking for yesterday, but couldn't while rushing round. Couldn't have been looking very hard as a quick search this morning and, ta-dar! I think that curve is for Advanced LIGO , Standard LIGO is about one order of magintude less sensitive.

Yes, I don't think we need to start rethinking gravitational wave theory just yet, it's not too surprising that nothing has been detected by LIGO so far. Lets wait for Advanced LIGO first (2009) James -------------------- |
