Projects: Pioneer Anomaly
Facts
At-a-Glance Technical Information
Until just recently, only about 11 years of the more than 30 years of Pioneer
Doppler data (velocity data derived from the Doppler shift of the received
frequency of the Pioneer signal) had been analyzed, and the Pioneer anomaly
remained. The Planetary Society stepped in and funded the effort to recover
and validate these precious data. We have recovered large parts of the
30-year histories of the two spacecraft, and the data are now being collected,
arranged, validated, and written to modern media. Here we present at-a-glance
technical information about the spacecraft and the data recovery. More »
Frequently
Asked Questions About the Pioneer Anomaly
Never, in 25 years, have we see seen such a response to a letter from The Planetary
Society. From around the world came letters and e-mails cheering us on
-- and asking for more information. To speed the flow of information, we’ve
compiled answers to the questions most often asked. More »
“What
is a New Physics?”
If the Pioneer anomaly can be attributed to the spacecraft or the way we track
it, it could refine our understanding of spacecraft and the way they fly. If
the answer lies in the solar system environment, it would be a new discovery
about the nature of our universe. More »
