Pioneer Anomaly Update

The Planetary Society has posted an interesting update on the Pioneer Anomaly especially about the fact that they’ve managed to recover almost all of the original telemetry data as well as the doppler shift information they were after.

The original tapes were to have been destroyed after 7 years, but as they say:

Fortunately, this is not what happened in the case of the Pioneer missions. Not only were the original magnetic tapes not destroyed but, in the early 1990s, before deterioration would have made the tapes unusable, they were copied to much more durable magneto-optical media. Since then, the files, about 40 gigabytes in total, have been copied to modern computers and we have now developed tools to extract information from them.
