Could Heat Radiation Solve the Pioneer Anomaly?

Click For Summary
SUMMARY

The discussion centers on the potential resolution of the Pioneer anomaly through enhanced heat radiation models. Participants reference improved measurements of the Earth's gravitational field and question whether these advancements could explain the observed flyby energy gains. The conversation also touches on the implications of special relativity as discussed in Jean Paul Mbelek's paper, which suggests that existing models may not fully account for transverse Doppler effects. Overall, the dialogue emphasizes the need for further investigation into these scientific theories and their implications for space exploration.

PREREQUISITES
  • Understanding of heat radiation models in astrophysics
  • Familiarity with gravitational field measurements
  • Knowledge of the Pioneer anomaly and its significance
  • Basic principles of special relativity and Doppler effects
NEXT STEPS
  • Research advanced heat radiation models and their applications in astrophysics

The very likely explanation of the apparent Pioneer anomaly through improved heat radiation models (https://www.physicsforums.com/showthread.php?t=486509".

As luck would have it, just today I stumble upon an article on improved measurements of the Earth's gravitational field by the http://www.cbc.ca/news/technology/story/2011/04/01/tech-earth-gravity.html". I'd imagine the differences between this new model and previous ones to be rather small, but still, could they be enough to account for the flyby energy gains?

Of course, I'm happy to hear about any and all related thoughts, as well.

Have you seen the paper "Special relativity may account for the spacecraft flyby anomalies" by Jean Paul Mbelek, http://arxiv.org/abs/0809.1888" ?

I'd seen the paper previously, but thanks for bringing it back to my attention. However, I was under the impression that NASA claimed that they did account for transverse Doppler effects, though I can't seem to find anything on that right now. It seems to me that this should be easy enough to settle if the paper is right, so why is there still talk about an anomaly?
