The Mariner 10 spacecraft used to explore the planet Mercury in 1974 used BPSK with
to transmit image data back to Earth (a distance of about 1.6 × 108 km). The spacecraft transmitter operated at 2.295 GHz, with an antenna gain of 27.6 dB and a carrier power of 16.8 W. The ground station had an antenna with a gain of 61.3 dB and an overall system noise temperature of 13.5 K. Find the maximum possible data rate
