[QUOTE="SelfSim, post: 77651145, member: 354922"] Thanks for that! :) The NASA Voyager site (FAQs) says: [I]'Even if science data won't likely be collected after 2025, engineering data could continue to be returned for several more years. The two Voyager spacecraft could remain in the range of the Deep Space Network {DSN} through about 2036, depending on how much power the spacecraft still have to transmit a signal back to Earth'.[/I] Notice the design of the DSN becomes the limiting factor here. My line of query here is really about the actual known maximum distance over which radio communications has been, (or will have been), achieved. SETI enthusiasts imagine far greater distance radios comms is achievable in order to establish dialogue with their believed-in, beloved ETIs. Nowadays, laser based comms is likely to expand these distances by orders of magnitude .. (albeit requiring a totally different bunch of ground segment limiting criteria). I think laser comms represents a major breakthrough, so SETI radio technology is now virtually obsolete in this particular modern-day hunt for the Holy Grail. [/QUOTE]
