An interplanetary spacecraft far beyond Earth’s orbit communicates with an equatorial ground station on the Earth. Calculate the maximum Doppler shift seen at X-band (8.4 GHz) due just to the Earth’s revolution around the Sun and Earth’s rotation (combined). (Ignore any component due to the velocity of the satellite.) -Assume the spacecraft in the question above is exiting the Solar System at the solar escape velocity and is 5AU from the Sun. Repeat including this effect.
