Tilley enjoys tracking down signals from “dead” satellites, zombie satellites, and spy satellites, but the MRO was a first for him. “MRO’s signal is weak, but it is one of the louder signals in Mars orbit,” he said. “The spacecraft has a large dish antenna it uses as a relay for other Mars missions. With the proximity of Mars these days, it was the perfect time to try.” | Tilley enjoys tracking down signals from “dead” satellites, zombie satellites, and spy satellites, but the MRO was a first for him. “MRO’s signal is weak, but it is one of the louder signals in Mars orbit,” he said. “The spacecraft has a large dish antenna it uses as a relay for other Mars missions.
