“...Is the signal being received by the Hubble, one of those huge antennas on Earth? Curious.” [poconopundit, post 82]
The Hubble Space Telescope senses near ultraviolet (300-400 nanometer wavelength), visible light (300-700 nanometer wavelength), and near infrared (750-1400 nanometer wavelength). Nothing to do with Voyager, nor other spacecraft.
Voyager 1 receives commands at a radio frequency of 2100 MHz, and sends responses at 2300 MHz and 8400 MHz. NASA’s Deep Space Network receives Voyager’s transmissions: antennas are all on Earth’s surface, at Goldstone (near Barstow, CA), near Madrid, in Spain, and near Canberra, in Australia.
Thank you. I learned something. It’s interesting.
