  • Mars Rover to Earth: "Where to now?"
    orientation is unknown. DSN antennas communicate with far-flung spacecraft at frequencies of 2.2, 8.4 and 32 GHz. The omnidirectional UHF antenna communicates through orbiters Mars Odyssey and Mars Global Surveyor passing overhead. About half of all communications will go through the HGA, a 0.28-m

    appliances. Antennas. Any conducting surface or mesh can act as a reflector for some ranges of frequencies. If the spacing in a conductive mesh is less than one quarter of the wavelength of a signal, it will be blocked. (Thank you Michael Faraday, 1791-1867). Those of us old enough to remember VHF and UHF
