(1) What would be the data transmission rate?
(2) How big would the radio antenna be? How does angular resolution scale with the antenna's diameter? How does the thermal noise scale with the diameter?
(3) What kind of cryocooler can maintain the antenna at low temperatures?
(4) How would you protect the satellite against radiation effects?
