Was Pioneer 10 driven off course by the Biefeld-Brown Effect?

Newton & Einstein, Meet Biefeld & Brown

(This is a repost of something that appeared in my WordPress dashboard that warrants a fresh look and some further exploration (original post dated May 17, 2008).  I have been thinking a lot about the ‘Biefeld Brown’ Effect – it’s curious history and the several occasions when knowledgeable observers said ‘yes, there is something there that conventional physics does not account for.’  And then I see where astrophysicists are unable to explain this ‘Pioneer Anomaly’ and have to wonder if a better understanding of The Biefeld Brown Effect (the “BBE”?) might solve the riddle.  So I’m fresh-posting this, and will return to it in the days or weeks ahead. – PS – February 17, 2023: )

…or do they just need to add Townsend Brown to their equations:

Beyond the edge of the solar system, something has gradually dragged two of America’s oldest space probes — Pioneer 10 and Pioneer 11 — a quarter-million miles off course. Astrophysicists have struggled 15 years in vain to identify the infinitesimal force at play. The Pioneer anomaly, as it is called, throws a monkey wrench into celestial mechanics.

The anomaly officially materialized in 1988, 16 years after NASA launched Pioneer 10 toward the outer planets. The 568-pound spacecraft had been designed to stay in radio contact with Earth just 21 months, time enough for it to become the first spacecraft to pass through the asteroid belt, the first to fly past Jupiter and the first to visit the outer solar system. The plutonium-powered probe, however, transmitted data 31 years until 2003.

As it sped through space, a specialist in radio-wave physics named John Anderson at NASA’s Jet Propulsion Laboratory noticed an odd thing. The spacecraft was drifting off course. The discrepancy was less than a few hundred-millionths of an inch per second for every second of spaceflight, accumulating year after year across billions of miles. Then Pioneer 11, an identical probe escaping the solar system in the opposite direction, also started to veer off course at the same rate.

I thought they solved this one a while back…. something to do with the Biefeld-Brown effect working through the spacecrafts’ solar panels. Anybody remember when that came up a while back?

  1. Neither of the Pioneer or Voyager craft have solar panels. They use radioisotope thermal electric generators. There are a lot of ideas and “explanations” to account for the slight accelerative anomaly, but no final word on it yet.
