The engineers at GSFC say you will need the DSN. The smallest DSN antenna is 26m and that is used only for LEO (a couple thousand km).

You talk about "red tape" like moving a huge radio telescope is some kind of formality, and you quoted a figure of 3.5m with no apparent engineering basis. I find this ridiculous.



The red tape isnt moving the dish - its getting someone to agree to let them mount a feedhorn for the proper band, and the needed radio hardware.

Moving the dish to me seems like the least difficult part, as it pales in the complexity to mounting the hardware.

For what its worth both Voyager probes feature S-Band Antennas - I have trouble believing we cant talk to those either on S-Band.
