For those curious about the downlink data rates used by Voyager, it uses 40 bps for engg. data and 160 bps for science data. It requires use of the 70m antenna at the 3 DSN sites. A 1.4 kbps rate is supported with 5 arrayed antennas at Madrid.

Voyager 1 is 24 billion km away. Tx power = 23W. Rx power = -160 dBm (1e-19 watts). A WiFi signal is > 10 billion times stronger!

Earlier data rates (kbps) for V2:
From Jupiter: 115.2
Saturn: 44.8
Uranus: 29.9
Neptune: 21.6
