Richard Stephenson and Dave Jones tour the DSS43 dish in Canberra to explain how NASA communicates with the Voyager 2 spacecraft.

Detailed look at how the 70m DSS43 NASA Canberra Deep Space dish is used to talk to the Voyager 2 probe 17 billion km from earth. Part of the NASA/CSIRO Deep Space Communications Complex at Tidbinbilla in Canberra Australia. Huge thanks to Richard Stephenson who stayed back after a 12 hour night shift to record this!

On “After 37 years, Voyager has fired up its trajectory thrusters”

There are high gain antennas on both ends, and use of error correcting codes, as well as extremely high grade low noise amplifiers on the Earth side. The Voyagers have a 3.7m diameter parabolic radio dish, larger than the Hubble space telescope's mirror even. That alone provides a huge amount of gain on communications. Additionally, the spacecraft have 10s of watts of power available for transmitting signals, which is a fair bit considering (while on the other end the ground stations have up to hundreds of thousands of watts to transmit). The ground-stations in the deep space network (DSN) are tens of meters across, a small antenna is 34m, the biggest ones are 70m across. That also provides…

Haven't worked in this field, but here are some episodes discussing the topic: link link link link link link to this video I think what you are talking about is mostly just normal engineering in the sense that the process is similar. What really makes space unique isn't space as such but that there is no real-world (real-space?) testing, no inspections after the fact or do-overs.

Yes, there was even some new lately. "Voyager Spacecraft Detect an Increase in The Density of Space Outside The Solar System" link Dave Jones made a coupe of videos about the Deep Space Station in Canberra. link to this video

…the Voyager probes is 'only' 3.7 meters. Still... not a cell phone antenna. That said, the transmit power of the Voyagers is tiny in comparison to ours and it is closer to that of the cell phone analogy- still more, however, at about 23 watts 1. So, our end task of receiving that, by the time it gets to us, is damn impressive indeed I think. 0 link to this video 1 link…
