Did anyone ever find out why pioneer 10 had an anomalous acceleration of 10^ - 8 cm/s/s towards the Sun?
AFAIK it's still an open question ... one of the few 'true anomolies' in astronomy/celestial mechanics/etc.kurious said:Did anyone ever find out why pioneer 10 had an anomalous acceleration of 10^ - 8 cm/s/s towards the Sun?

That would increase the force they exert on a star.
Wouldn't the effect be observable for other space probes too? For example, Voyager 1 and Voyager 2; maybe Ulysses? Even WMAP?? Do you think LISA could test your idea?Thomas2 said:As indicated on my page http://www.physicsmyths.org.uk/lightspeed.htm, the apparent anomalous acceleration could be due to a systematic error in relating the travel time of the communication signal to the distance of the spacecraft .
The Pioneer 10 spacecraft was a NASA space probe launched in 1972 to explore the outer solar system. It was the first spacecraft to travel through the asteroid belt and to encounter Jupiter.
Anomalous acceleration refers to the unexpected change in velocity of a spacecraft that cannot be explained by known physical forces. In the case of Pioneer 10, this anomalous acceleration was observed as a slight deviation from its expected trajectory.
The anomalous acceleration of Pioneer 10 was first discovered in the 1980s by a team of scientists led by John Anderson at NASA's Jet Propulsion Laboratory. They noticed that the spacecraft was deviating from its expected trajectory by about 400 miles per year.
There are several theories that have been proposed to explain the anomalous acceleration of Pioneer 10. These include the effects of solar radiation pressure, outgassing of gases from the spacecraft, and the presence of dark matter or a new force of nature.
The Pioneer 10 anomaly has sparked much interest and debate among scientists. If it is not due to any known physical force, it could indicate the presence of new physics that we do not yet understand. It also highlights the need for further research and exploration in the outer solar system to better understand the mysterious forces at play.
