So you want to track NASA at Mars? Here is an very interesting read from one amature work at receiving signal from NASA space crafts that are not only enroute to Mars but also in orbit around Mars. Just some of the spacecrafts that he has received are Bepi-Colombo, Mars Express, MRO, and OSIRIS-ReX to name some of the few. He still hope to expand his system even more to pick up Juno that is in orbit around Jupiter.
So do you think you have an antenna farm just read his white paper what he has done to do this impossible task.
